Clay is an impressive platform.
Built for a very specific kind of user.

Clay has built one of the most sophisticated GTM workflow tools in the market and earned a valuation that validates just how important B2B data has become. But it is a power tool — built for revenue engineers and agencies, not for everyday sales and research users.

Clay's achievement

A $5B valuation that validates the entire market.

Clay's success is worth acknowledging directly. Reaching a $5 billion valuation means investors and thousands of sophisticated GTM teams believe deeply in the value of structured B2B data and workflow automation.

That validation matters. It confirms that the problem Fullinfo is also solving — giving people access to better, broader, more structured company intelligence — is genuinely valuable and commercially significant.

Clay built something remarkable for a specific audience. Their platform connects 150+ data providers, automates complex prospecting workflows, and has created an entirely new category of GTM engineering. For the teams it was built for, it is genuinely powerful.

The question is whether you are that team — or whether you need something that works without the workflow.

The data underneath

150 providers. The same underlying data.

Clay's waterfall connects 150+ providers and tries each in sequence until one returns a result. But the vast majority of those providers draw from the same source — LinkedIn-scraped data from brokers like ProxyCurl or CoreSignal. More providers does not mean more unique coverage. It largely means more routes to the same records.

🔗

Patchwork of providers

When you stitch together 150 providers, you inherit 150 different data quality standards, 150 different refresh cycles, and 150 different interpretations of what a company record should look like. There is no single source of truth — just whichever provider happens to win the waterfall on any given record.

⚠️

Inherited LinkedIn limitations

Clay's core company and contact data inherits the same structural limitations as every other LinkedIn-derived tool. Single broad industry tag. Limited SMB coverage. English-language bias. The waterfall doesn't fix the underlying data model — it just adds more routes into it.

Google Maps — the SMB workaround

Clay added Google Maps as an acknowledgement that LinkedIn data misses local and SMB businesses. But Google Maps requires setting a location and radius — it is designed for "what's near me," not for market discovery. Finding pilates studios across North America means querying city by city, hundreds of times.

The TAM cost problem

In Clay, you enrich first.
Then you search.
That's an expensive order.

Clay's workflow requires you to pull a broad list of companies first, enrich each one with data from your chosen providers, and then apply filters to find the ones you actually want. The enrichment step happens before the filtering step.

If you are looking for a specific niche — say, independent vehicle inspection companies across Germany — you might need to enrich 50,000 records to find the 300 that match. You pay for all 50,000 enrichment calls. The 49,700 you didn't want cost just as much as the 300 you did.

Fullinfo inverts this entirely. You describe what you're looking for and receive structured results directly. You never pay to enrich records you don't need.

Clay — finding a niche TAM

Independent vehicle inspection companies in Germany

Starting list pulled from LinkedIn data ~50,000 companies

Enrichment calls required (pre-filter) 50,000 × cost per call

Relevant results after filtering ~300 companies

Records you paid for but didn't need 49,700

Wasted enrichment spend ~99% of total cost

Fullinfo — same search

"Independent vehicle inspection companies in Germany"

✓ Structured results returned directly — no enrichment step

✓ Only pay for the companies you actually want

✓ No workflow to build — one search, one result

Different tools for different users

Clay is a power tool.
Fullinfo is for everyone.

This is not a question of which tool is better — it is a question of which tool is right for you. Clay requires significant investment in learning, setup, and maintenance. The volume of supporting infrastructure they have built around the product reflects that honestly.

Clay is built for

GTM engineers and RevOps teams who build automated prospecting pipelines

Agencies managing outbound workflows for multiple tech-forward clients

Teams with the time and skill to complete Clay University and build and maintain complex table-and-waterfall workflows

Companies with large, predictable outbound volumes where the enrichment cost per record is justified

English-language, LinkedIn-visible markets with well-defined ICP

Clay University, cohort classes, a community Slack, a job board, an expert marketplace, and live events all exist for a reason — this tool has a steep learning curve.

Fullinfo is built for

Any salesperson, researcher, procurement manager, or recruiter who needs to find and understand companies

Teams doing niche market discovery where the target universe is small and the starting list is unknown

Organizations researching markets outside North America and Western Europe — where LinkedIn data is thin

Anyone who needs SMB, local, or B2C businesses that simply don't appear in LinkedIn-derived data

Users who want to search first and pay only for what they find relevant

No university. No pipeline to build. Search, find, use.

Feature comparison

Fullinfo vs Clay

A focused comparison on data, search, and accessibility. Clay's workflow automation, CRM integrations, and sequencing features are outside this scope — those are areas where Clay has no equivalent in Fullinfo, and Fullinfo has no ambition to replicate them.
