AiSDR runs your outreach. Sellton runs your whole GTM.
AiSDR is a sharp AI SDR for sending email and LinkedIn and handling the replies. Sellton is Autonomous Revenue Infrastructure that owns the entire lane, research to pipeline, in your own captured voice.
What AiSDR does well
Give AiSDR real credit. It is one of the sharper AI SDRs on the market. It researches prospects on live buying signals like funding rounds, hiring surges, and tech-stack shifts, builds lead lists from a plain-English description, writes researched multichannel messages across email and LinkedIn, handles replies and objections, and books meetings straight onto a rep's calendar. Setup is fast, pricing is published openly, and on the send side it genuinely runs without a rep babysitting it. If what you need is an outbound engine that sends and replies, it is a legitimate pick.
Where the tile ends
AiSDR owns outbound execution and replies. It does not own the front of the lane or the tail. It personalizes from a persona you configure rather than your actual captured voice, so the words come out polished but not quite yours. Its AI Strategist proposes campaign angles fast, but it does not extract durable positioning from how you really win deals. And once a meeting is booked, managing the pipeline drops back to your CRM and your team. To run the full lane you still stitch AiSDR to a strategist or agency for positioning and voice, plus your CRM and ops for everything after the meeting.
The GTM lane, covered
Eight stages from research to execution. AiSDR owns its tile. Sellton runs the whole lane.
| Stage | AiSDR | Sellton |
|---|---|---|
| Research | Partial Strong prospect-side research on buying signals. Understanding your own business comes from settings and a persona. | Full |
| Positioning | Partial The AI Strategist spins up campaign angles fast. It does not pull durable positioning from how you win. | Full |
| ICP | Full Defines your ICP and builds lists from a plain-English description. Genuinely good here. | Full |
| Brand / voice | Partial Personalized per prospect, but written from a generated persona, not your own voice. | Full |
| Outbound | Full Multichannel email and LinkedIn sequencing, executed. This is the core. | Full |
| Follow-up | Full Handles replies, objections, and conditional follow-ups without a rep touching each one. | Full |
| Pipeline | Partial Books meetings and syncs to your CRM. Managing pipeline stays with your team. | Full |
| Execution | Full Runs the outreach autonomously once set up. Set-and-go on the send side. | Full |
The differences that matter

What it really costs
AiSDR's Explore plan is $900 a month for 800 researched contacts, and Scale is $2,500, both on quarterly contracts with contact caps. That price covers the send. It does not cover the strategist or agency who feeds it your positioning and voice, or the CRM and ops work to manage what comes back after a meeting is booked. Add those pieces up in the GTM cost calculator and you land right back near the agency number the tool was meant to replace, roughly $2,500-plus a month for the work plus the tools around it. Sellton is pay-per-use across the entire lane, so you pay for what it actually executes, not a seat and a contact cap you hope to fill.
Do not buy a tile. Own the lane.
