Attio vs Clay

Clay finds and enriches records from 150+ data providers in a table, billed in actions and data credits from $185 a month. Many teams use both: Clay's official Attio app syncs records both ways.

Data credits pay for marketplace data, from $0.05 each. Bringing your own provider key skips data credits but still uses actions. Top-ups cost a 30% premium. | |
| Firmographics on records you hold, no emailsBuilt-in enrichment on records you hold: company name, description, logo, category, location, employee count, ARR and funding raised; person name, description, picture, social and location. No email or phone finding. | Emails and phones from 150+ providersEmails, phone numbers, company and people data from 150+ providers, run as waterfalls.

The HTTP API column and webhook automation need Growth. On reading table data by API, Clay's pages differ: the developer docs list Tables on Enterprise plans, while Clay University says basic row reads work on any plan and structured queries need Enterprise. | |

Apps used across workspaces use OAuth 2.0. | clay-api-key header, OAuth for MCPA clay-api-key header. You create the key in the app under API and CLI, pick its scopes, and it is shown once.

Each record created inline through a reference counts as one more write. | Not published; search caps by planA per-workspace limit with no published number; 429 comes with Retry-After, and X-RateLimit headers are sent when available. Search results are capped by plan: 500 per request and 1,000,000 per 30 days on paid plans. Going over a search cap returns HTTP 402. | |
| No batch endpoint; upsert by unique attributeNo batch record endpoint. Upsert one record at a time by a unique attribute (domain for companies, email for people), so a repeat write updates the same record. | Batch runs over JSONL; 50,000-row tablesRoutines can run in batch over an uploaded JSONL file. Tables cap at 50,000 rows on Launch and Growth. | |

Questions people ask
What is Clay com used for?
Clay is used to find people and companies and enrich them in a table, pulling from 150+ data providers and its AI agent, then sending the results to a CRM, a sequencer or its own email Sequencer. It is not a CRM; Attio is the CRM in this pair.
What is data enrichment in clay?
In Clay you add an enrichment column to a table and it fills each row from a data provider or a waterfall of providers. Each option shows its cost per row in data credits, for example about 1.1 for a work email waterfall, and rows where nothing is found are not charged. Attio's own enrichment fills company and person profile fields on records you already hold.
Can Clay and Attio work together?
Yes. Clay has an official app in Attio's app directory that syncs prospect and account data both ways. You import Attio records or lists into Clay, enrich and qualify them, and write the results back to Attio.
Which one is free to start?
Both have a free plan. Attio Free gives up to 3 seats, 50,000 records, the API, webhooks and MCP with no card. Clay Free gives 500 actions and 100 data credits a month and up to 200 rows per table, without phone enrichment or the HTTP API column.
Do both have an MCP server?
Yes, both are official and use OAuth. Attio's at https://mcp.attio.com/mcp reads and writes CRM records, lists, notes and tasks. Clay's at https://api.clay.com/v3/mcp finds and enriches companies and contacts and charges the same credits as the app.
