👇truth. It is/was actually mind-blowing.
our last Board meeting was a major turning point. every single question... "let's ask the product". every single answer made sense. it's the closest thing to "God view" I've seen in a business. just watch the video... it's hard to put into words what @markitecht and @MichaelPici are building at @Day_ai_app

Locked In Founders of the Day award goes to @markitecht and @MichaelPici 🏆 Congrats on @Day_ai_app's Series A!
Today we're announcing Day AI's $20M Series A led by @sequoia, and that we're now generally available. We've spent 18 months building what we believe is the Cursor of CRM. Here's what that means 🧵

Replying to @markitecht
@markitecht has done it again & it's high time for the world to experience it. We’ve treated CRMs like glorified databases for decades: useful, but passive. In an era where data is exploding and shared context is compounding, the way we work and make decisions has to level up... and fast. Christopher is reinventing the category he himself helped build by launching Day AI: the first CRM that is truly architected for LLMs. Built on a rich context graph with long running agents, @Day_ai_app can turn organizational relationships into decisions and decisions into action - across GTM, product, partnerships, hiring… wherever context is the unlock. Try it and you'll feel the difference. It's the first time I’ve seen the single pane of glass promise actually delivered. Congrats to the team on the Series A and public launch. Speaking for myself and @sound_ventures_, we're honored to be part of the journey.

Want to validate buyer personas in your current crm it’s a week of manual imports and exports and more work. @Day_ai_app it’s a simple question. That unlocks marketing, sales, and ops Congrats @markitecht and @MichaelPici Day is incredible.

sales led growth -> product led growth -> agent led growth
Sequoia partner @sonyatweetybird says we're going from the age of product-led growth to the age of agent-led growth. "You see this most clearly if you're using Claude Code actively. It says, 'Hey, for a database, you should use Supabase. For hosting, use Vercel.' It's choosing for you, the stuff you should be using." "Product-led growth brought us closer to the vision of 'best product wins,' but ultimately people are still lazy. They can't read all the reviews, and they kind of default to what looks cool on the website." "Whereas your agent has infinite time to go and make these choices for you. It can go and read all the documentation, read all the user comments, and figure out [what you need] for your use case."

✨ Systems of Action, Episode 1 ✨ feat. Christopher O'Donnell of Day.ai. “Anybody who says they’re doing AI-native CRM, I just buy them flowers and a big, 10-pound bag of coffee and I just say, ‘Absolutely, good luck, have fun.’ It’s brutal,” @markitecht told us recently. That’s exactly what he’s been doing for the past two years as CEO & co-founder of Day.ai. And while he’s aware of the massive effort it will take to challenge legacy CRM players like Salesforce, there are few people better equipped to take that on. 📺 Dive into the full episode with @MikeDroesch & @darsh_cp >>> bessemervp.team/43XfKLj

I've always wondered why CRM is such a gigantic and unassailable piece of software. @markitecht shares the story of building the only $1B+ revenue CRM challenger to Salesforce @HubSpot... and what's coming for self-driving CRM @Day_ai_app @gradypb seq.vc/189

"With Day.ai, we have seen a glimpse of the future." 🫡 i've learned to look forward to @gradypb and @sonyatweetybird's annual letter — a lovely new tradition. grateful for the thoughtful discussion of what it means to be an ai-native product at the application layer and humbled to be included as an example. the more we build at @Day_ai_app, the more clear it becomes that starting from scratch with LLMs as a given is not just a superficial change we could've bolted on to an existing system. it's a deep, counterintuitive shift in how we design and build *everything* all the way from UI, to data storage and privacy, and everywhere in between. the real magic has been to watch those shifts compound on each other with each new layer of AI processing we put on top of the last. getting the foundations right is the only way to unlock that compounding intelligence, and requires a willingness to set aside many of our assumptions about building products from past experience. link to article in replies.

@Day_ai_app is the real deal - very very impressed with the comprehensive approach and speed of development they are demonstrating. I suggest getting on their waitlist.
My calendar is packed with meetings across multiple companies. People wonder how I manage follow-ups and keep everything so organized. Now that it's coming out of stealth, I can reveal that the tool I use is Day. It takes meeting notes. Organizes followups. And even adds data to my CRM. It's people-centric, like me. I can get you access if you want to try it. Link in first comment. Congrats to Christopher & the team on the $4M raise.

I’ve had early access to this AI-based CRM and it’s a complete game-changer. No more updating records. What happens in meetings, email, etc, automatically gets summarized and added to the CRM. Get early access to Day.ai in my partner link below.

For several years I’ve been very curious about what might finally disrupt the CRM hundreds of attempts at a “better” salesforce have failed. It would have to be “different” Because different is better than better. I think it’s day.ai.
Day.ai is Reimagining CRM for the AI Age. Today, we’re excited to announce our $4M fundraise, led by @sequoia with participation from @pillar_vc, @w_conviction, @Stage2Capital, @InspiredCap, @20SALES_vc and a number of amazing angels.

For 13 years, I've witnessed @markitecht in action as a product visionary and @MichaelPici as a PLG whisperer. Today, the duo launched @day_ai_app to productize customer obsession. We couldn't be prouder to partner with them on this journey. sequoiacap.com/article/partn…
