Enterprise search and Day AI do different jobs.

What Day AI is: built for go-to-market.
Day AI is built for go-to-market teams. It reads the meetings, email, calls, and Slack a team chooses to connect, turns them into one shared customer record, and puts GTM AI agents to work on it.
Organized around customers.
Day AI is organized around customers, deals, and the conversations about them, so every rep and every agent starts from what actually happened with each account.
Every meeting, email, and call.
The record builds itself from the conversations your team connects, and each person decides what teammates and agents can see of their email and meetings.
Agents that do the work.
GTM AI agents turn the graph into finished work: the follow-up drafted, the next meeting prepped, the pipeline kept current, with every value showing its sources.
One GTM context graph for every rep and every agent.
A revenue team needs the whole picture of every customer: every meeting, email, call, and Slack thread with a customer, linked to the right people, companies, and deals. Day AI builds that GTM context graph for you and keeps it current as conversations happen, so nobody has to type it in.
Every rep and every agent reads the same graph, scoped to what each person is allowed to see. Edit a field or a permission and the change lands in every view and every agent right away. New hires inherit the team’s memory on day one instead of starting from zero.
GTM AI agents that do the work.
Day AI’s agents are standing teammates: each has a job description, a schedule, and skills, and works from the GTM context graph on the permissions of the person it works for. They draft the follow-up on the right thread, propose the record updates a call implied, and prep the next meeting, held for a person to approve wherever you want one. RevOps builds a role once and ships it to every rep. Our founder, Christopher, works closely with three every day. Open one to see what it had waiting for him.
Reviews my new-business pipeline every morning and flags the deals where my involvement would actually move them, with a specific action for each. Keeps my opportunities current as things change.
My BDR. Every morning he hunts for CEOs and CPOs who should see Day AI, researches each one, and hands me a prioritized list of demo targets, with a reason they’ll care and a clear way in.
Follows me through my day and mines my meetings for content, maintaining my ideas page, then fleshes the best ones into full drafts by evening. Also works my podcast and speaking pipeline: checking new invitations, prepping me for upcoming shows, and finding warm intros through my network.
What it’s worth, once it’s the whole team.
More capacity per rep
Prospecting, prep, and follow-ups run in the background, so reps spend their time on real conversations.
More deals moved forward
Agents catch the slipping commitment and the stale deal and hand reps finished next steps, so fewer opportunities stall.
Faster ramp
New hires inherit the team’s memory and a working roster of agents on day one.

Why us
Built by the person who built the last system of record that scaled.
Day AI’s founder, Christopher O’Donnell, was responsible for HubSpot’s product from 2011 to 2021. He built the Marketing Hub, built the Sales Hub and its CRM in 2014, and built and ran the team that shipped Service Hub and Data Hub. Building the system a revenue org runs on is the exact problem he has solved before. He has spent the years since ChatGPT launched building what comes after the system of record, for the age of agents.

What is Day AI?+
Day AI is the customer memory and agent platform for go-to-market teams. Even the best CRM only holds a fraction of what actually happened with your customers. Day AI is what comes after CRM. It builds a self-updating customer record from every meeting, email, and call, and runs governed agents that create finished work on top of it, with every fact and every action traced to source conversations. It does everything teams use a CRM for, without the data entry, and does what a CRM never could. Agents prospect, prep every meeting, draft follow-ups, keep the pipeline clean, and much more, giving every rep added selling capacity that used to require hiring additional people. It runs in place of Salesforce or HubSpot or as a layer on top of them.
