Bold Agent Kit vs AiSDR is a comparison of two AI SDRs built for different lists. AiSDR finds and researches prospects, works them by email and LinkedIn with call steps through Aircall, and sizes its plans by researched contacts a month; Bold Agent Kit works the list you already have by email, text and a call the agent places itself, answers inbound on the same agent, and books the meeting. At the time of writing, AiSDR's published plans start at $250 a month; Bold Agent Kit is $25 a month for the whole account, with no cap on contacts or mailboxes.

AiSDR sizes its plans by AI-researched contacts a month. At the time of writing, its published plans start at $250 a month for 200 researched contacts, one user, one domain, three mailboxes and one LinkedIn account, and its larger plans raise each of those numbers. All of its plans are billed monthly, the two larger ones on quarterly contracts, with a discount for paying annually.
Bold Agent Kit has no allowance, because it does no per-contact research. You bring the list, and contacts and lists are unlimited. The plan is $25 a month, or $200 a year, for the whole account: every agent, every channel, every mailbox and every contact, with a client login for each agent you choose to share. Your AI provider bills you for the model and your carrier for texts and calls, both at cost.
So the month's volume is set by your list and the sending caps you choose, not by the plan. The dashboard shows what the month produced, in replies, meetings and value won, and there is no count running down in the background.
AiSDR's plans include email through Gmail or Outlook, LinkedIn connection requests, direct messages and InMail, and AI call steps in sequences using the Aircall dialer, with call scripts and follow-ups based on the conversation. Its largest plan adds AI videos in messages and AI voice notes in LinkedIn messages.
Bold Agent Kit's sequence is email, text and call. The email goes from your own mailbox, the text from your own account with one of nine SMS carriers, and the call from your own Twilio number, where the agent speaks in real time from your script, answers from your knowledge base, and books the slot if the person agrees. Each step has its own delay and send condition, opened, not opened, clicked or not clicked, inside the days, hours and time zone you set.
Bold Agent Kit does not send LinkedIn messages. If LinkedIn is where your buyers answer, that is a real difference, and it is covered honestly further down this page.
AiSDR's plans include automatic replies or a co-pilot mode, with objections and questions handled and meetings booked, and it lists Calendly and HubSpot calendar integration. In Bold Agent Kit, a reply on any channel stops the sequence for that person and the agent answers it, from your Q&A pairs, documents and data points and the pages of your site it may link to, once per thread.
When the person is ready, it offers real open slots from Google Calendar, Microsoft 365, Calendly, Cal.com, Acuity, Zoho Bookings, Square Appointments or HubSpot Meetings, and books the one they pick. It cannot book a time that was not free. Every reply, email, text or call transcript, lands in one inbox, newest first, tagged by channel. Reply yourself and the agent stands down on that thread; hand it back when you are done.
Outbound sends people to your site and your phone. In Bold Agent Kit the same agent is waiting there: the website chat, through one line of script, in your colour with your greeting; inbound calls to your Twilio number, answered in real time with a recording and transcript; texts to your number; and DMs on Messenger, Instagram, WhatsApp, Telegram, LINE, Viber, Slack, Discord, Bluesky, Reddit and X, on your own app credentials.
It answers from the same knowledge base as the campaign and reads the same record for that person, so the prospect who ignored three emails and then asked a question in the chat is one row with one history. An agent can also run inbound only, with no campaign at all, on the same subscription.
AiSDR is an AI SDR that finds prospects and works them. Its site describes live AI lead search from a plain-language description of your ideal customer, a native database of more than 300 million leads alongside Sales Navigator data, and prospecting on signals such as company news, hiring, job changes and the technology a company uses. It researches each lead before writing, sends email through Gmail or Outlook, runs LinkedIn connection requests, messages and InMail, adds AI call steps through the Aircall dialer, handles replies and objections, and books meetings. It syncs with HubSpot and Salesforce, and it creates mailboxes, warms domains and rotates inboxes for you.
AiSDR publishes its prices. At the time of writing, its published plans start at $250 a month, and each plan is sized by AI-researched contacts a month, with a set number of users, domains, mailboxes and LinkedIn accounts. The entry plan runs month to month; the two larger plans are billed monthly on quarterly contracts. That fits a product built around finding and researching each prospect. It is a different model from the one a business with its own list needs, and that difference is usually why people compare the two, or go looking for an AiSDR alternative.
Bold Agent Kit is built for the business with its own list. It has no contact database and no research service. Your list comes from a CSV, a segment of a connected CRM, or the Chrome side panel, which pulls email addresses, phone numbers and social profile links off the pages you browse. One agent works it by email, text and call as one campaign, on as many mailboxes as you connect and your own number, answers the replies from your own material, and books real open slots in your calendar. The same agent answers the website chat, inbound calls and social DMs.
The plan is $25 a month or $200 a year for the whole account, with unlimited agents, contacts, lists and mailboxes, and a 7-day free trial. You pay your AI provider for the model and your carrier for texts and calls, both at cost, usually a few dollars a month. Nothing is counted per contact, per mailbox or per seat.
Each is about scope and pricing structure, and whether they fit the list and the channels the business actually has, not about whether AiSDR does what it says.
Every AiSDR plan comes with a number of AI-researched contacts a month. For a team prospecting net-new accounts, the research is what the contacts are for. For a business working its own customers and leads, the count sets how many people it can reach in a month, and a bigger list points to a bigger plan, whether or not those people needed researching.
Each AiSDR plan sets how many domains, mailboxes and LinkedIn accounts it includes, starting from one domain and three mailboxes on the entry plan. Teams that want to spread their volume across more addresses, or run several brands or clients each on its own domain, find themselves planning around those numbers rather than around the list.
AiSDR's entry plan runs month to month, and its larger plans are billed monthly on quarterly contracts, a choice its pricing page explains by the time outbound takes to warm up and produce results. A business that wants more volume without a longer commitment, or an agency whose clients come and go, may want those two things kept apart.
Outreach sends people to your website, your phone number and your social pages, and that is often where they answer: a chat at 10pm, a call back on Thursday, a DM on Instagram. A team that wants the agent that sent the emails to answer all of those too, from the same memory of each person, wants outbound and inbound on one agent.
Bold Agent Kit does not research prospects or send LinkedIn messages. It works the list you have on email, text and phone, answers everything that comes back, and books the meeting.
Connect every mailbox you want on every domain you own, and a campaign rotates across the healthy ones inside hourly caps per mailbox and a daily cap per sender. Add a number from one of nine SMS carriers, and Twilio for calls. Nothing is counted against an allowance: the only limits are the caps and schedules you set.
Email on day 0, text on day 2, a call on day 5, and on for as long as you want, each step with its own delay and send condition. A reply, a booking or an opt-out on any channel ends the sequence everywhere and cancels anything queued, and a campaign sends nothing until you press Start.
Campaign replies, website chat, inbound calls, texts and DMs are answered by the same agent from your material, once per thread, and the threads you named go to a person. When they are ready it offers real open slots and books one, and the booking shows in the funnel against the channel that won it.
The biggest structural difference is where the limits sit. AiSDR plans set a number of researched contacts a month, and a number of domains, mailboxes and LinkedIn accounts. Bold Agent Kit sets none of those. An agent holds every mailbox you connect, on any domain, Gmail and Outlook by app password and anything else by SMTP and IMAP, and a campaign rotates its sends across all of them. Contacts and lists are unlimited, and twenty mailboxes across four domains cost the same as one.
Each mailbox that opts in warms up on a ramp that starts at five a day, and carries a health score out of 100 built from SPF, DKIM and DMARC on its domain, seven days of real sends and bounces, and where its warm-up mail is landing, with the reasons listed. When a mailbox's bounce rate or spam placement passes a threshold, it leaves rotation on its own before it damages the domain, and the campaign carries on through the others. Every campaign email carries a one-click unsubscribe, honoured on mail already in the queue.
Four things, each answering one of the reasons above. The sequence and the reply handling will feel familiar; the limits and the channels change.
Unlimited contacts, mailboxes and domains. The month's reach is set by the caps and the schedule you choose, not by an allowance.
Email, text and a call placed by the agent itself, in one campaign, on your own mailboxes, carrier account and Twilio number.
$25 a month or $200 a year for the account, cancel any time, with a 7-day free trial. No quarterly term for more volume.
Campaign replies, website chat, calls and DMs answered by one agent from one knowledge base, with a person able to take over any thread.
Every send, reply, text, call, visit and booking is recorded against a person and reported as a funnel, per agent and across all agents. What you measure is what the list produced, not how much of an allowance it used.
The funnel counts people rather than messages: how many the agent reached, how many replied, how many went on to visit your website and how many converted, with the total value won and the median time to convert. Opens and clicks are recorded per campaign and written to each person's history, so a step conditioned on "opened" has real data behind it. Set a goal with a dollar value, as a page rule or a manual "won", and each campaign reports what it made.
Below the funnel, a channel table shows where each person first responded and which channel they were on when they converted, so you can see whether the email books meetings on its own, whether the text on day 2 is doing the work, or whether the call is what closes. One row per person shows every send, reply, text, call, visit and booking in order, and visit triggers follow up when a known person returns to a page you named, after a delay and on the channel they last used. Page goals and triggers need a one-line snippet on your site.
Built from the cookie, email address and phone number attached to that contact, so activity months apart on different channels appears on one row.
Page goals and visit triggers require a one-line snippet on your website. Conversations, bookings and manually marking a deal won work without it.
What each does for the jobs an AI SDR is bought for. The AiSDR column is taken from AiSDR's own website, feature pages and pricing page on the date shown below the table.

AiSDR and Bold Agent Kit share the middle of the job, the sequence, the replies and the booking, and differ at the edges. AiSDR finds and researches prospects, works LinkedIn as well as email, and sizes its published plans by researched contacts a month, with set numbers of domains, mailboxes and LinkedIn accounts. Bold Agent Kit starts from a list you already have, adds texts and agent-placed calls, answers inbound on the same agent, and costs $25 a month or $200 a year for the account with no contact or mailbox cap, plus your AI provider and carrier at cost.
We checked AiSDR’s public website on 11 September 2026 for this comparison. Plans and features change, so check aisdr.com for the current detail. AiSDR is a trademark of its owner, and Bold Agent Kit is not affiliated with or endorsed by it.
Three situations people are in when they compare the two. The honest answer is different in each.
You have run AiSDR on email, most of your meetings come from people who were already in your CRM, and you are planning around a contact allowance and a mailbox count you no longer need. Your contacts are in HubSpot, your openers and objection answers are proven, and what you want now is the same follow-up on your own accounts, with a text and a call added and no cap on the list.
Some teams keep AiSDR on LinkedIn-led prospecting of new accounts and put a Bold Agent Kit agent on the rest: the customers already in the CRM, the website chat, the phone and the social inboxes. The two never share a list. AiSDR works the accounts it found; the agent wins back past customers by email, text and call, and answers whoever comes in through your site, your number or your DMs.
If your buyers live on LinkedIn and you need them found, AiSDR is built for that. It runs LinkedIn connection requests, messages and InMail from one sequence, with voice notes and video on its largest plan, searches for prospects live from a plain-language description of your ideal customer across a 300M+ lead database and Sales Navigator, tracks signals such as job changes and hiring, researches each lead before it writes, and syncs with Salesforce as well as HubSpot. A B2B team that sells through LinkedIn may well be better served there.
Connect the tools you already run and the agent works them like an assistant would: it takes appointments straight into your calendar, writes notes and outcomes back to the CRM, and reads your store to see what somebody has bought before it answers them.
Bookings are real, not guesses. It is only ever given slots that are genuinely free, and it can only take one it actually offered — so it cannot invent a time or double-book you. The same connection pulls a segment of past customers into a list when you want to run a campaign at them.

Any OpenAI APIA new address sending forty cold emails a day gets filtered, and takes the domain with it. Mailboxes that opt into warm-up send each other ordinary mail on a ramp, starting at five a day. The receiving mailbox finds each message, moves it out of spam if it landed there, marks it read and replies to a share of them.
Each mailbox carries a health score out of 100 — SPF, DKIM and DMARC on the sending domain, seven days of real sends and bounces, and where its own warm-up mail is landing — with the reasons listed. A mailbox whose bounce rate or spam placement passes a threshold is pulled out of campaign rotation automatically, before it damages the domain.
Three steps. The campaign is created as a draft and shows every contact, every mailbox and every step on a review screen before anything leaves.
Name the agent, choose a model and paste your API key from one of 16 providers. Then give it what your AiSDR campaigns relied on: the value proposition for each persona, the objections you hear and your answers to them as Q&A pairs, your prices and terms as data points, your case material as documents, and the pages of your site it may link to. If you ran several personas, consider one agent per offer; agents are unlimited.
Save the email templates, the text and the call script once. Write the instructions last: tone, the offer it may make, the questions it asks before it offers a slot, and the replies it should hand to a person rather than answer.
Add every mailbox you want the agent to send from, on as many domains as you own, with an app password for Gmail and Outlook or SMTP and IMAP for anything else. Switch warm-up on so each ramps from five a day, check the health scores, and fix any SPF, DKIM or DMARC record they name. Add a number from one of nine SMS carriers, and Twilio for calls.
Connect the calendar the agent books into and the CRM that holds your contacts. Load the list from a HubSpot or GoHighLevel segment, a CSV, or what the Chrome side panel extracted from the pages you browsed. Add the chat snippet and social accounts if the same agent should answer inbound.
Build the sequence: the email on day 0, a second email to the openers, a text on day 2 to those who did not open, a call on day 5 to whoever is still silent. Set the days, hours and time zone, the hourly caps per mailbox and number, and read the whole plan on the review screen. Nothing sends until you press Start.
Then work the inbox. Replies and inbound messages are answered by the agent, the threads you named come to you, bookings land in the calendar, and opt-outs are honoured on every channel. When the funnel says it works, widen the list: there is no allowance to upgrade.
One account runs unlimited agents, one per client, and nothing is shared between them. A knowledge base belongs to a single agent, and content from one agent is never used to generate replies for another.
Invite a client by email address and they get their own login, which opens onto the one agent you gave them: its conversations, its numbers, its analytics and a reply box. They cannot see your other clients, your API keys, your settings or your billing. Access is deny-by-default.
No seat tiers, no credit packs, no per-agent or per-channel pricing, and nothing held back behind an enterprise call.

It depends on the buyer. For a B2B team that sells through LinkedIn, needs prospects found and researched, and runs Salesforce, AiSDR covers ground Bold Agent Kit does not: LinkedIn steps, a lead database, live search and research on every lead. For a business, agency or small team that already has its list and wants it worked by email, text and a call the agent places itself, with inbound chat, calls and DMs answered by the same agent and no cap on contacts or mailboxes, Bold Agent Kit is the better fit, at $25 a month for the whole account.
AiSDR finds and researches prospects, from live AI search, a 300M+ lead database and Sales Navigator data, and works them by email, LinkedIn and call steps through the Aircall dialer, on plans sized by researched contacts a month with set numbers of domains, mailboxes and LinkedIn accounts. Bold Agent Kit has no database and no LinkedIn: it works the list you bring by email, text and a call the agent places itself, answers inbound on the same agent, and costs $25 a month or $200 a year for the account, with unlimited contacts and mailboxes.
At the time of writing, AiSDR's published plans start at $250 a month. Each plan is sized by AI-researched contacts a month and includes a set number of users, domains, mailboxes and LinkedIn accounts. All plans are billed monthly; the entry plan runs month to month, the larger two are on quarterly contracts, and annual billing carries a discount. Bold Agent Kit is $25 a month, or $200 a year, for the whole account, with unlimited agents, contacts and mailboxes. Your AI provider and carrier bill you directly, at cost, for the model and for texts and calls.
Start with the contacts. AiSDR syncs both ways with HubSpot, so if your contacts are there, Bold Agent Kit can import a HubSpot segment straight into a contact list; otherwise, upload a CSV. Use only contacts you are free to keep using under your agreements. Then connect your own mailboxes on your own domains and switch warm-up on, move your objection answers into Q&A pairs, and rebuild the sequence as email, text and call steps. Run the 7-day trial on a slice of the list nothing else is working, and compare the funnel before moving the rest.
When LinkedIn and prospecting are the job. AiSDR runs LinkedIn connection requests, messages and InMail inside its sequences, searches for prospects live from a plain-language description of your ideal customer across a 300M+ lead database and Sales Navigator, tracks signals such as job changes, hiring and LinkedIn engagement, researches each lead before it writes, and syncs with Salesforce as well as HubSpot. It also lists managed service options. A B2B team whose buyers answer on LinkedIn, and who need them found, may well be better served by it.
No. Bold Agent Kit does not send LinkedIn connection requests, messages or InMail, and it does not connect to LinkedIn. Its outbound channels are email, text messages and phone calls, as steps in one campaign. For inbound and replies it also covers website chat and DMs on Messenger, Instagram, WhatsApp, Telegram, LINE, Viber, Slack, Discord, Bluesky, Reddit and X, each on your own app credentials. If LinkedIn is where your buyers reply, that is a genuine reason to choose a tool that works it.
No. Contacts and lists are unlimited, and an agent holds as many mailboxes as you connect, on as many domains as you own, with no per-mailbox fee. Agents are unlimited too. What limits a campaign is what you set: the days, hours and time zone it may send, the hourly cap per mailbox and per number, and a daily cap per sender. Each mailbox is warmed, carries a health score out of 100, and leaves rotation automatically if its bounces or spam placement pass a threshold, so volume spreads across healthy addresses.
No. Bold Agent Kit has no lead database, live lead search or per-lead research. Lists come from a CSV you upload, a segment imported from a connected CRM such as HubSpot or GoHighLevel, or the Chrome side panel, which extracts email addresses, phone numbers and social profile links from the web page you have open, with a deep scan of a domain and a queue for a CSV of sites. Before it writes or replies, the agent reads the contact's record in the connected CRM or store, and answers from the knowledge base you gave it.
