Where “imagine if” gets to work. We've helped 500+ companies (like @NotionHQ, @Roblox, @Uber, @Square) take a straighter path from idea to product-market fit.

After @tobi published his now-famous AI memo, you probably saw similar posts from other founders and CEOs flood this platform. But most companies are still in the “memos and demos” phase — ambitious plans and mandates, “AI-first” roadmaps on board decks, flashy features and

The demand for clean, always-on power is exploding, and the grid can't keep up. The team at Endurance Energy is going after one of the biggest untapped sources on the planet: geothermal heat beneath the seafloor. They're building systems to deliver gigawatts of zero-emission

There’s no single archetype of someone who works at @AppliedInt. But most fall into one of three buckets: The domain specialists (like AV simulation PhDs), new talent (there’s always a big cohort of recent grads) and ex-founder or CTO types (they infuse the “startup” energy, even

I think this point from @malharhar, who is one of the earliest employees @AppliedInt is so right.

There are few people in the world I've met who are as dedicated, intense, and ambitious as @SurbhiSarnaSF. I had the honor of first getting to know Surbhi when we were both working at YC, and it was so obvious from my very first interaction that she was someone who would leave a

"The only team that sits at the intersection of product, revenue, users, perception, and community is marketing." Sheila Joglekar Vashee's definition of great marketing isn't storytelling. It's creating coherence. Excited to share our next episode of Executive Function with the

I remember first meeting @jakebolling & being 'wowd' by his desire to transform an otherwise overlooked industry. We knew we had to invest. 12 months later, Scotch launched. 3 months after that, pre-empted for their A. Now, Scotch has passed a $1B GPV run-rate. Scotch is

Today I’m thrilled to announce Scotch has raised a $20M Series A, led by VMG Partners, with participation from @firstround , @LererHippeau , and @TobaCapital . In 2024, we set out to fix something that's been broken for 30 years: the technology running America's 40,000+

Applied Intuition has a practice called the culture table. Co-founders @qasar and Peter Ludwig, plus a few other leads (specifically, not managers) meet regularly to make sure manager bloat isn’t creeping in as the headcount has scaled past 1,000. Every six months, ICs score

When I joined @AppliedInt, back in early 2019, it was just a handful of engineers working above a bar in Sunnyvale. The website didn’t really tell you what we were. We just wanted to build amazing products for the real world, from fighter jets to hundred ton trucks to autonomous

It’s rare to find a former CTO who’s both technically world-class and a commercial savant. @jgreze is one of the few I’ve worked with who’s both. He’s putting that combo to work building @TownAI with @tonydevincenzi, an insanely talented product thinker and designer. I've known

Back in February, I got early access to @TownAI. Now 93% of @firstround is using it. There was never a top-down mandate — it went viral inside First Round the way great products do. Today, Town announced its $55M Series A. Huge congrats to @jgreze, @tonydevincenzi and the whole
