Clay builds the list. Then the real work starts.
Clay is the best data and research layer in outbound. But data is one tile. Positioning, voice, sending, follow-up, and pipeline are still yours to build. Sellton runs the whole lane.
What Clay does well
Give Clay its due. It is the best programmable data engine in go-to-market, and it is not close. Waterfall enrichment chains 150-plus providers, so you still find the record when any single source comes up empty. Claygent research agents run AI on every row. Signals catch job changes and promotions the moment they happen. If your problem is finding accurate, enriched, deeply researched data at scale, almost nothing does it better. That tile is theirs, and they earned it.
Where the tile ends
Clay hands you a beautifully enriched list and a set of tables you built. It does not decide how you should be positioned. It does not interview you to sharpen your offer or ICP. It does not learn to write in your voice. Its Sequencer sends email, but LinkedIn and most volume sending still live in HeyReach, Smartlead, or Instantly, and reply handling and pipeline live somewhere else again. You are the one stitching the data tile to five other tools and doing the strategy by hand. Clay is the engine. You are still the whole rest of the car.
The GTM lane, covered
Eight stages from research to execution. Clay owns its tile. Sellton runs the whole lane.
| Stage | Clay | Sellton |
|---|---|---|
| Research | Full Waterfall enrichment across 150-plus providers plus Claygent AI research. Best in class. | Full |
| Positioning | None Does not define your positioning, offer, or messaging. You bring that. | Full |
| ICP | Partial Sources and scores lists against an ICP you define. It does not build the ICP strategy for you. | Full |
| Brand / voice | None Generates AI copy, but not your own captured LinkedIn and email voice. | Full |
| Outbound | Partial Native email Sequencer. LinkedIn and volume sending run through HeyReach, Smartlead, or Instantly. | Full |
| Follow-up | Partial Scheduled email follow-up steps. Autonomous reply handling is not its job. | Full |
| Pipeline | Partial Enriches, routes, and scores leads into your CRM. It feeds pipeline, it does not manage it. | Full |
| Execution | Partial Executes the tables and plays you build and maintain. A human operates the whole thing. | Full |
The differences that matter
Clay
You define the positioning, offer, and ICP. Clay executes against what you decided.
Sellton
Sellton researches you, runs an agency-style AI interview, and builds your Brand DNA, positioning, offer, and editable ICP for you. You approve, you do not author.
Clay
AI-generated copy that reads like AI unless you engineer the prompts.
Sellton
Sellton captures your real LinkedIn and email voice and writes as you.
Clay
The data tile only. Sending, replies, and pipeline live in HeyReach, Smartlead, Instantly, or your CRM.
Sellton
One system: research, positioning, ICP, voice, outbound on LinkedIn and email, follow-up, and pipeline.
Clay
A powerful builder you operate. Someone designs the tables, owns the credits, keeps the plays running.
Sellton
Runs autonomously, 24/7, with humans approving strategy.
Clay
Two credit meters, Data Credits and Actions, that you budget and watch. Cost climbs fast at team scale.
Sellton
Pay-per-use for what it executes. No seats, no retainer, no lock-in.
What it really costs
Add it up honestly. Clay's paid self-serve tiers run roughly $150 to $500 a month, and that is before the data credits, the sending tool, the LinkedIn tool, the CRM, and the person who runs all of it. At team scale, real Clay spend climbs into the tens of thousands a year. An agency doing this whole lane charges $2,500-plus a month on top of around $4k of tooling. Run your own numbers in the GTM cost calculator: the fragmented stack you assemble around Clay versus Sellton's pay-per-use, where you only pay for what it executes.

Is Sellton just another Clay?+
No. Clay is a data and enrichment engine you operate. Sellton is Autonomous Revenue Infrastructure that runs the entire outbound lane, from research and positioning to your voice, outbound, follow-up, and pipeline, with humans approving strategy.
Does Clay send outreach for me?+
Partly. Clay added a native email Sequencer, but LinkedIn and most volume sending still run through tools like HeyReach, Smartlead, or Instantly. Sellton sends on both LinkedIn and email, in your captured voice.
Can I use both Clay and Sellton?+
You can. Some teams keep Clay as a pure data source. But if the goal is one system that runs the whole lane without stitching five tools together, Sellton replaces most of that stack.
How is the pricing different?+
Clay meters Data Credits and Actions across tiered plans, and real cost climbs with team size. Sellton is pay-per-use with no seats, no retainer, and no lock-in.
