If the real job is finding emails for a list of people, find and verify them first, then load them into whichever CRM you pick.

[ Book a call ](/book)[ See case studies ](/case-studies) 05 ## Questions people ask Is Attio cheaper than HubSpot? At entry level HubSpot's list price is lower: Starter is $20 a seat a month, against $35 a user a month billed annually for Attio Plus. Higher up, Attio Pro is $79 a user a month billed annually and HubSpot Professional is $90 billed annually plus $1,500 onboarding. Both have a free plan. Which free plan gives more? Attio Free covers up to 3 seats, 50,000 records and up to 3 objects, with API, webhooks, workflows and MCP. HubSpot's free tools cover up to 2 users and 1,000 contacts, with API access and no workflows. How do Attio and HubSpot handle duplicate companies created by API? Attio treats company domain as unique: a plain create with an existing domain is rejected, and an upsert updates the existing company. HubSpot dedupes contacts on email, but companies created through the API are not deduplicated by domain, so search before you create. Can I bulk import records through the API? HubSpot has batch endpoints of 100 records per call and an Imports API that takes up to 80,000,000 rows a day. Attio's API has no batch record endpoint, so records go one per call within its 25 writes a second. Do Attio and HubSpot have MCP servers? Yes. Attio's is at `https://mcp.attio.com/mcp` and HubSpot's at `https://mcp.hubspot.com`. Both sign in with OAuth and can read and write CRM records. ## Related [![](/_astro/attio.CoO4UDxn_ZRTvHO.webp)Attio API review](/tool-directory/crm/attio)[![](/_astro/hubspot.ClO2484y_SluoY.webp)HubSpot API review](/tool-directory/crm/hubspot)[![](/_astro/apollo.DNg6-7d3.svg)![](/_astro/attio.CoO4UDxn_ZRTvHO.webp)Apollo vs Attio](/tool-directory/compare/apollo-vs-attio)[![](/_astro/apollo.DNg6-7d3.svg)![](/_astro/hubspot.ClO2484y_SluoY.webp)Apollo vs HubSpot](/tool-directory/compare/apollo-vs-hubspot)[![](/_astro/attio.CoO4UDxn_ZRTvHO.webp)![](/_astro/clay.CHDKXtEw_Z1QRVH4.webp)Attio vs Clay](/tool-directory/compare/attio-vs-clay)[![](/_astro/attio.CoO4UDxn_ZRTvHO.webp)![](/_astro/salesforce.C2obBAuF.svg)Attio vs Salesforce](/tool-directory/compare/attio-vs-salesforce) Read from [attio.com/pricing](https://attio.com/pricing), [hubspot.com/pricing/sales](https://www.hubspot.com/pricing/sales?currencyCode=USD&overrideLocale=en-us) and each tool's API docs.
