Apollo vs Attio

Attio scores higher on the AgentReady, 88/100 against 64/100. They differ on 11 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Apollo. The AI sales platform for smarter, faster revenue growth.

Attio. Attio is the CRM that builds pipeline, advances deals, and grows accounts around the clock.

Where Apollo is ahead

Apollo passes search discoverable, clear canonical domain and public docs discoverable, and Attio does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: limits / constraints documented. Attio misses it.

And on adopt, official typescript sdk, official python sdk and cli available. Attio misses those.

Finally, on operate, canonical workflow succeeds and observable execution. Attio misses those.

Where Attio is ahead

Attio passes llms-full.txt / full agent docs, and Apollo does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: structured api reference. Apollo misses it.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, no mandatory sales call, programmatic credential creation, fast time to first request, copyable quickstart, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable. If your agent needs any of those, you will be building it yourself either way.

Score, pillar by pillar

The AgentReady splits into four pillars, scored separately, because a product can be easy to find and still impossible to adopt.

Discover. Apollo leads 93 to 92. Apollo misses llms-full.txt / full agent docs; Attio misses search discoverable, clear canonical domain, public docs discoverable.

Understand is whether an agent can read the docs and work out how the API behaves before calling it. Attio leads 83 to 38. Apollo misses structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented; Attio misses openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. Attio leads 88 to 70. Apollo misses no mandatory sales call, programmatic credential creation, fast time to first request, copyable quickstart; Attio misses no mandatory sales call, programmatic credential creation, fast time to first request, copyable quickstart, official typescript sdk, official python sdk, cli available.

Operate. Attio leads 89 to 56. Apollo misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable; Attio misses canonical workflow succeeds, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution.
