What is Clay, exactly?
Clay is a data enrichment powerhouse. It connects to over 100 data sources — LinkedIn, Apollo, Clearbit, Crunchbase, and more — and lets you build automated workflows to research and enrich prospect data at scale.
In the right hands, with the right RevOps team, Clay is impressive. It can pull company funding rounds, detect hiring signals, find contact emails, and feed that data into your outreach sequences.
The catch: Clay builds the list. Clay enriches the data. Clay does not write the messages. Clay does not send anything. Clay does not book meetings. You — or your team — still does all of that.
Formula. goes further — all the way to the booked meeting
Formula. starts where Clay stops. The agent identifies who to contact, detects real buying signals (who liked your competitor's posts, who visited your profile), writes a personalized message for each prospect, sends it on LinkedIn and via email, follows up at the right time, qualifies the conversation, and when the prospect is ready to meet — proposes slots from your calendar and books the meeting automatically.
You get a notification. You swipe to validate. That is it.
Who is each tool built for?

- You have a validated B2B offer generating revenue
- You want qualified meetings without managing a tool
- You have no RevOps team or engineering resources
- You want results in weeks, not months
- You want to control everything from your phone
Clay is built for you if...
- You have a dedicated RevOps or growth engineering team
- You need highly customized data enrichment workflows
- You already have a strong outreach stack and just need better data
- You have technical resources to build and maintain automations
- You are comfortable spending weeks on setup before seeing results
The key difference
Clay is a tool for people who know how to prospect and want better data to do it. It assumes you know what you are doing. It amplifies an existing process.
Formula. replaces the process entirely. You do not need to know how to prospect. You do not need to write messages. You do not need to manage sequences. The agent handles all of it.
One line: Clay gives you data. You still do the work. Formula. does the work for you.
If you have a RevOps team and an existing outreach stack, Clay can make it sharper. If you are a founder, consultant, or sales team who just wants more qualified meetings without the overhead — Formula. is built for you.
Frequently asked questions
What is the fundamental difference between Formula. and Clay?

Does the agent book meetings automatically?
