An AI SDR software alternative for a founder with no sales team
An AI SDR is a category of software that runs sales development, prospecting and outreach for sales teams. Their site
AI SDR software runs outbound at volume for a sales team: hundreds or thousands of researched contacts a month, sequences across email and LinkedIn, meetings booked into a CRM, priced by contact allowance or by quote. Kamu sends a few good emails a day and then does the rest of growth, for a founder who has no sales team to hand the meetings to.
An AI SDR agent does the job a sales development rep does: builds a list, researches each person, writes and sends the outreach, works the replies and books the meeting. Three vendors show what the category looks like from the buyer's side.
AiSDR sells self-serve. As of September 2026 its Solo plan is $250 a month for 200 AI-researched contacts, one user, one domain and three mailboxes, month to month. Explore is $900 a month for 800 contacts, billed quarterly, and Scale is $2,500 a month for 2,500 contacts with Salesforce sync. It sends by email and LinkedIn, syncs with HubSpot, and names revenue teams, sales leaders and founders as its buyers.
11x sells Alice, an outbound digital worker across email, phone, LinkedIn and SMS, and Julian, an inbound phone agent. There is no price on the site; you book a demo. It names sales, RevOps and marketing teams at mid-market and enterprise companies.
Artisan sells Ava, an autonomous AI BDR that finds and enriches leads, writes and sends, handles replies and books meetings, with data, deliverability, sequencing and a dialer in one platform. The homepage routes to a demo request.
The shape is consistent. AI SDR tools are metered in researched contacts or quoted per company, they assume a CRM to write into and someone to take the call, and the more capable tiers are sold through a conversation. That is the right design for a team with a quota.
Kamu is designed for the founder who has none of that. It writes between 10 and 200 emails a day depending on plan, one at a time, each to a person it found and verified and each opening on something that person shipped or wrote. It answers replies on its next run and stops when someone says no. There is no per-seat price because there is one of you. Outreach is one of six jobs: the same agent writes articles, posts from what shipped, keeps a landing page, files listings and builds a paused video ad. The plans are €25 to €349 a month, published.
Side by side
| Kamu | An AI SDR | |
|---|---|---|
| What it is | A growth agent: outreach plus content, social, a landing page, listings and ads, for one founder. | Software that runs sales development for a team: prospecting, sequences, replies and booking, into a CRM. |
| Who it is for | A founder with no sales team, who will take the reply themselves. | Sales and revenue teams with quota. AiSDR names revenue teams and sales leaders; 11x names sales, RevOps and marketing at mid-market and enterprise. |
| Volume | 10 to 200 emails a day by plan, one at a time. The category wins this row. | AiSDR meters 200, 800 or 2,500 researched contacts a month by plan; 11x and Artisan do not publish limits. |
| How you buy | Self-serve, monthly, cancel any month. €25, €49, €149 or €349. | AiSDR from $250 a month self-serve, with quarterly billing above that; 11x and Artisan by demo and quote, as of September 2026. |
| Channels | Email from your own domain, and LinkedIn messages when connected. No phone. | Email and LinkedIn everywhere; 11x adds phone and SMS, and Artisan includes a dialer. |
| Where the meetings go | Into your calendar. Kamu drops your meeting link into the thread when someone asks for a call. | Into the CRM: HubSpot and Salesforce sync at AiSDR, CRM integration at 11x, and a team to take the call. |
| What is refused | An unverified address, a follow-up after a no, any send to a suppressed address across every product you run, and open-tracking pixels. | Varies by vendor and is rarely published as a list. Check each one's unsubscribe and deliverability handling before you sign. |
| What else it does | Articles through Ghost or WordPress after approval, posts from what shipped, a landing page, directory listings and a paused Meta video ad. | Sales development, and the data and dialer around it. Marketing is somebody else's product. |
When An AI SDR is the better choice
Buy AI SDR software when you have a sales team. If reps carry quota, a CRM is kept clean and there are people to take meetings the moment they land, an agent metered in hundreds or thousands of researched contacts a month is the right instrument, and Kamu's cap of 200 emails a day on its largest plan is a ceiling you would hit in the first week. The category also wins on the machinery of sales: two-way CRM sync, a dialer, phone and SMS in the sequence, and at 11x and Artisan a sales-led onboarding with a named person accountable for making it work. If outbound is your only gap and a specialist beats something broader, AiSDR's Solo plan at $250 a month is a real self-serve option for a small team. And if what you want to buy is meetings, in volume, with a manager watching the funnel, none of that is what Kamu is for.
Questions
Is Kamu an AI SDR agent?
For one of its six jobs, yes. Kamu finds people, writes to them one at a time, answers replies and stops on a no, which is the sales development loop. It is not metered in contacts or seats and it does not write into a CRM. The same agent then goes and does the rest of growth. If you want only the SDR part at volume, a product built for a sales team goes deeper on it.
What does AI SDR software cost?
It depends on who publishes. AiSDR lists Solo at $250 a month, Explore at $900 and Scale at $2,500 as of September 2026, metered by researched contacts. 11x and Artisan do not publish prices and sell through a demo. Kamu is €25 to €349 a month with outreach included in every plan. Per contact reached the AI SDR tools cost less. Per month, for one founder, Kamu does.
Do I need a CRM to use Kamu?
No. Every person Kamu writes to has one row in its own leads list, with everything both sides said, and your meeting link goes into the thread when somebody asks for a call. AI SDR software assumes a CRM and a team behind it, which is why HubSpot and Salesforce sync sit on the front page at AiSDR and 11x. If you already run one, that is a point in the category's favour.
Which AI SDR tools does this site compare directly?
Artisan and 11x each have their own page, and Soleur, another autonomous agent, has one too. The sending platforms Instantly, Smartlead, lemlist and Reply.io are compared as tools you operate rather than as agents. Every figure on those pages was read from the vendor's own site on the date shown, and where a vendor publishes no price the page says so.
