Attribution stack for the first B2B customers.

Capture first-party session source, landing page, consented lead source, buyer-reported discovery and CRM outcome as separate fields. Measure completeness and contradictions in the evidence before calculating channel efficiency.

THE DIRECT ANSWER

Capture first-party session source, landing page, consented lead source, buyer-reported discovery and CRM outcome as separate fields. Early teams either record nothing or implement a complex multi-touch model on tiny, noisy samples. A UTM parameter or referrer does not prove that a channel caused the purchase.

About Eli · facts checked 20 October 2026

What Eli is: AI agents that do your marketing work

Eli is an AI growth team for B2B companies: four autonomous AI agents for AI search, your website, conversions and Meta ads. They work every day; you approve what matters. You do not do the marketing work yourself: Eli's agents do it every day, also when you are not logged in, and ask you only when a decision is yours.

  • AI Search Agent: gets you named when buyers ask ChatGPT and Gemini what to buy.
  • Website Agent: fixes the pages where buyers decide; changes go live after your yes.
  • Conversion Agent: tracks which visits become customers, through the Eli site tag.
  • Paid Ads Agent: tests Meta ads inside your budget, after a tracking check.

Eli is for founders of B2B software and service companies, often 11 to 50 people, whose website gets visitors but not enough customers, and who have no marketing team to work on it.

You use Eli from ChatGPT or Claude, through Eli's MCP connector, or in your Eli account at hireeli.io, and Eli sends you one short report a week. There is no new dashboard to learn.

Eli Free is free forever: one website, a diagnosis in the first 48 hours, then 5 answers once a week, no card. Eli Autopilot has all four agents (AI Search, Website, Conversion and Paid Ads for Meta ads, Meta ads by invitation while Meta reviews Eli) on every plan; only the capacity differs: Launch $99, Core $249 or Grow $599 a month (or €99, €249 and €599). Eli Done for You is $1,500 or €1,500 a month: Grow's capacity, set up and run with Eli's team. Every plan is monthly and can be cancelled anytime, and every account starts free. Enterprise is scoped and priced in a call. Your ad budget is separate and goes directly to Meta.

On G2, Eli is rated 4.8 out of 5 from 2 verified reviews (checked 20 October 2026). G2 reviews

You approve Eli's first change and your ad budget. After that you can let Eli improve pages and publish by itself, and you can undo anything. More money or anything new still waits for your yes. "Stop everything" works at any time. Eli never promises a ranking, a revenue figure, a multiple or a date. It tracks conversions, reports what it measured, and says so when it is too early to tell.
