Excited to announce our $12M Seed Round led by @LongJourneyVC
We’re an applied AI Lab building operational intelligence.
We're thrilled to work with incredible startups like @UseCorgi , @slashapp , @agentmail , and many more.
Our mission is to turn all of enterprise software into a prompt.
We do this by using frontier models and post training specific models on company data.
Thanks for the coverage @TimFernholz and @TechCrunch

I joined @GradientVC at the start of 2024 after 10 years as an operator or founder at Jobr, Newfront, and Vial.
I wasn’t sure if venture would be for me, but the chance to build the best platform for early AI founders was too compelling to miss.
Today marks another step in that journey; we’re launching Fund V: $220M, as a fully independent firm.
We sit in a unique spot: we take bets before ideas are obvious, lead rounds, and partner closely with founders through the highs and lows of building.
Our team is all former operators and engineers, so we bring real empathy for how insanely hard it is and a lot of curiosity for what’s next.
It's an absolute pleasure to work with @darian314 @thezbg, @Cdpetty, @denise_teng25, @EylulKayin, @jackie_eicholz, @kylerduffy, @vigsachi, and devon jarred!

My heart is with friends and all people of Lebanon. They are being subjugated to terror, and it is not even getting discussed in the media/news.
Entire region is suffering because of a few monsters. 💔

Will be the most impactful use of AI

Patrick Collison on what changes when biology becomes programmable: "We, humanity, have never cured a complex disease." "Most cardiovascular disease, most cancers, most autoimmune disease, most neurodegenerative disease... For none of them can we really say that we've cured it, that we understand the causal pathways in meaningful detail." "Then over the last 10 ish years... we’ve gotten three new classes of technology in biology." "If you put those together, you now have the ability… to read, think, and to write. And this starts to really feel like a new kind of Turing loop." @patrickc with @mntruell

One of the best AI products I've ever used built by the world class team at @yutori_ai
Scouts now available at yutori.com
Abhishek Das@abhshkdz
Today, we're making Scouts available to everyone! Earlier this year, Scouts was born out of a simple observation — that so many of life's background (or even foreground!) tasks have a recurring flavor, e.g. house hunting, early stages of travel planning, sourcing leads, discovering rare products, job search, staying on top of niche news / research / podcasts, discovering local events, etc. It's been gratifying to see all the love and feedback from our closed beta users who've helped shape the product over the last few months ❤️ With just a simple query, Scouts lets you deploy a team of AI agents to monitor anything for you. Running 24x7 in the background on the web. So you have the mental space to focus on what's most meaningful to you. The underlying agent architecture is incredibly powerful — subagents all the way down, powered by our own web navigation agent, and with access to way more tools / APIs than before. This what the future of interfacing with the web looks like. Where you're not sitting there manually browsing and refreshing, buried in tabs, ads, noise, distractions, context switches. Think Google Alerts on steroids. This has been, hands down, the most fun and challenging release from our team. As with all things agentic, there's a lot of noise out there, and every micro-decision matters in shipping reliable agents. To celebrate this release, we're offering all paid plans at 50% off, and here's a video we recently shot. Hope you like it.

Excited to share that I’ve joined @a16z as an Investment Partner.
I’ll be focusing on early-stage investing as part of a16z @speedrun, where we invest $1M in new startups and help them scale.
I first got to know a16z when I joined Lyft in 2019, where the firm was a major investor and Ben was on the board. I’ve always admired their unique approach to venture as a product, focus on content marketing, and culture of deep respect for the entrepreneur.
I’m thrilled to now join and serve founders alongside @andrewchen, @Tocelot, @JoshLu, @tkexpress11, @emilybenn12, @custo_lejla, @samshank, @far33d, @marcussegal, @ndrewlee, and the rest of the team.
Thank you to the incredible team at @BainCapVC – who gave me my first introduction to venture and the best training I could’ve asked for.
If you’re working on something new – I’d love to hear from you. It’s time to build!

The fundamental challenge with the sleep thing is that if I have 8 hours sleep 2 nights in a row I can't get to sleep the next few nights.
It used to take me 3 hours to get to sleep, and the only thing that drove a material delta in sleep onset time was sleeping less.
I get there sleep hygiene, CBTI, supplements, etc – I've tried everything for 10 years – but none actually work that well.
I suspect we need some sort of therapeutic intervention to actually solve sleep – a peptide or potentially headband are my top bets.

wow, I had more than 8 hours sleep for the first time in a while and I feel incredible. this sleep thing works
