Day.ai raises $20M from Sequoia to build an AI-native CRM that thinks like Claude, not a spreadsheet

Feb 2, 2026 with Christopher O'Donnell

Key Points

  • Day.ai raises $20M from Sequoia to build a CRM optimized for LLMs rather than human workflows, positioning AI as a foundational architecture choice instead of a surface layer.
  • When tested against HubSpot, Claude described Day.ai as naturally queryable while calling HubSpot 'like a spreadsheet,' giving O'Donnell an unsolicited product comparison he now uses in pitches.
  • O'Donnell is selling primarily to CEOs by demonstrating Day.ai as a live assistant that answers board questions in real time, departing from his HubSpot playbook of bottoms-up adoption through frontline reps.

Summary

Christopher O'Donnell, former head of product at HubSpot for roughly a decade, has raised $20 million for Day.ai, an AI-native CRM built from the ground up to serve AI agents rather than human data-entry workflows. Sequoia led the round, joined by Permanent Capital, Conviction, Sound Ventures, and Green Oaks.

O'Donnell argues that the CRM category is underestimating how much AI changes what's possible. Most incumbents treat AI as a layer on top of existing data structures, automating manual entry and improving integrations. Day.ai is built differently at the storage level, capturing and indexing everything said or done at a company in a format optimized for LLMs to explore relationships and answer questions in natural language.

The clearest illustration came from a customer who connected Claude to both HubSpot and Day.ai simultaneously. Claude described HubSpot as "like a spreadsheet" and Day.ai as everything it needs to answer any question. O'Donnell now uses that unsolicited review as a core piece of his pitch.

Go-to-market

The entry point is a meeting recorder that auto-updates deals, drafts follow-up emails, and surfaces workflow actions in real time. Most users unlock the deeper value within a week: the ability to query anything happening across the business. O'Donnell ran his own board meeting without slides. The Day.ai assistant was live on screen the whole time, fielding questions from the board instantly rather than queuing them for ops follow-up later. Sequoia partner Pat Grady, a Day.ai board member, posted about the experience.

O'Donnell is running two distinct go-to-market motions in parallel. Bottoms-up adoption through frontline reps remains important, the playbook he ran at HubSpot. But he is spending most of his time right now demoing the product personally to other CEOs, arguing the tool is most legible when you watch someone use it. The pitch lands as a chief of staff that watches everything, synthesizes it, and is always available.
