Signl vs Clay: tables or a data layer for agents

Clay orchestrates providers in a spreadsheet. Signl answers a question when an agent asks. Two different jobs, compared with our bias stated up front.

Clay is a table where you assemble data providers and run lists through them. Signl is a query interface an AI agent calls mid-conversation. The overlap is narrower than the category page suggests: one is built for repeatable bulk work, the other for open-ended questions asked once. Most teams that need both are not confused, they have two jobs.

Disclosure: Signl is ours. The criteria below are the ones we think matter, and where Clay is the better answer we have said so.

What each one actually is

Clay is an orchestration surface. You build a table, add rows from a source, and add columns that call providers, run conditions, or invoke an AI step. It has a waterfall model so a column can try several providers in order. The mental model is a spreadsheet that can call the internet, and it is a genuinely good one.

Signl is a data layer for agents. It runs as an MCP server exposing five read-only tools. There is no table, no canvas and no workflow builder. Your agent asks a question, gets structured rows back, and carries on in the same conversation.

The difference is not depth of features, it is where the work happens. Clay is a place you go. Signl is something your agent calls from wherever you already are.

Where Clay is genuinely better

We would rather say this plainly than have you discover it after signing up.

Bulk list work. Ten thousand rows through a defined sequence of steps is exactly what Clay is for, and pointing an agent at that job is the wrong shape entirely.

Repeatable workflows. A table that runs the same way every week, with conditions and branching, is deterministic work. Determinism is not what a model gives you.

Provider choice. Clay exposes the providers and lets you assemble the waterfall yourself. If you have opinions about which vendor to try first for which segment, that control is real and we do not offer it.

Breadth of integrations. Clay connects to far more sources and destinations than we do, and we are not trying to catch up.

Self-serve access. You can start today, with a card and no conversation. Signl starts with a demo call, which is a real cost to you if you would rather just try something this afternoon.

If your GTM motion is fundamentally list-based, Clay is the better purchase and this comparison should end here.

Where we are actually different

The work happens where you already are. No context switch into a data tool, no export, no re-import. The research and the writing sit in one conversation. For ad-hoc account work, that is most of the friction in the job.

Signals are native, not assembled. Funding, hiring and technology adoption are first-class types with an ICP score and two timestamps: when the event happened, and when we first detected it. You do not wire that up. See buying signals for what each type predicts, including what it does not.

You pay for results, not attempts. Credits are charged only when a verified contact comes back. A search that returns nothing is free, and so is a lookup that misses. We still pay providers for those misses, which is why we publish an enrichment attempt cap separately from credits on the fair use page. The distinction is worth understanding in any credit system: metering that counts attempts means you fund the failures.

Nothing writes anywhere. All five tools are read-only. That is a limitation and, we would argue, the right one for a model-driven surface.

Honest limits on our side

We are not a workflow tool and will not become one. No bulk export. Industry filtering covers 35 categories rather than an open taxonomy, and an unrecognised value returns an error listing what we accept rather than an empty result. Person-level signals cover contacts you have already enriched, not the whole market. Technology and department-headcount filters are Unlimited-plan only, capped at 30 searches per cycle. The full list is on what Signl covers, including the things people ask for that we do not have.

And access starts with a call rather than a signup form, which is a real barrier if you would rather evaluate on your own time.

The pricing comparison people actually want

Not directly comparable, and pretending otherwise would be the dishonest version of this page.

Clay meters actions and data credits separately. An action is a step your table performs; a data credit is consumed when a provider returns enrichment. The two decouple, which means a table can burn actions on rows that produce nothing usable. That is not a criticism, it reflects real underlying cost, but it does mean the sticker price is a floor rather than an estimate.

Signl meters one thing: verified contacts delivered. Searching is unlimited and costs nothing. Our pricing is not published; it is set on the call.

So the comparison depends entirely on your hit rate and your volume, and the only way to know is to run both against fifty accounts from your real ICP. That takes an afternoon and tells you more than any table on any vendor's website, including this one.

Using both

A stack we would consider sensible: Clay for list building and the repeatable weekly table, an agent-facing layer for the ad-hoc questions that come up between those runs. They fail at different things.

The mistake is running both against the same task, because you then pay two providers to find the same person. If you do use both, split by job, not by preference.

Frequently asked questions

Is Signl a Clay alternative?

Only for part of what Clay does. Clay is an orchestration surface: a table where you assemble providers, run enrichment in bulk and build repeatable workflows. Signl is a query interface for an AI agent. If your work is running a list through a sequence of steps, Clay is the better tool and we would say so.

How much does Clay cost?

As published on 25 August 2026, Clay has a free tier with 500 actions and 100 data credits per month, Launch starting at $167 per month, Growth starting at $446 per month, and custom Enterprise pricing on an annual commitment. Annual billing lowers the monthly-equivalent entry price. Check their pricing page, since these change.

What is the difference between actions and data credits?

In Clay's model an action is a step your table performs and a data credit is consumed when a provider returns enrichment. They are metered separately, which means a table can consume actions on rows that never produce a usable result. Understanding that split is the main thing that determines your real bill.

Can you use both Clay and Signl together?

Yes, and it is a reasonable stack. Clay handles list building and bulk workflows; an agent-facing data layer handles ad-hoc questions in the moment. The failure to avoid is running both against the same task, since duplicating enrichment across two providers means paying twice for the same contact.

Give your agent the whole market.
