Combine abundant power, free cooling, and nearby fiber, and entirely new infrastructure becomes possible.

[Sundeep Peechu @speechu]

The bottleneck in AI isn't models anymore. It's power.

Land is too contested. Space is too expensive.

There's a third way: the seafloor. ~400°C heat half a km down, 2°C water on top — the best thermal gradient on Earth, and the cheapest electrons on the market.

@ngavini Let’s go!!

[Peter Deng @pxd]

Tomorrow is Humans in the Loop, and we @Felicis are thrilled to featuring @extradotemail on stage as one of the companies pushing what's possible in consumer AI.

@ngavini, is an n=1 leader: one of Pinterest's earliest and most tenured product execs, who helped build the company from a small startup to a public company that's defined a new kind of consumer interface.

With Extra, Naveen is doing it again, but this time building an inbox for your life, starting with email. Extra takes a widespread pain of keeping up with your personal inbox and turns it into something intelligent and delightful.

And today, Extra is launching "handle it". Now, you delegate tasks to Extra - whether that's scheduling a meeting, confirming an appointment, or coordinating with friends, Extra will handle the back and forth. Extra is your life’s inbox and your life’s assistant. They are also removing the waitlist; Extra is now available on iOS and web.

Extra will be one of 20 companies taking the stage at Humans in the Loop in a rapid-fire demo showcase of some of the most creative, ambitious early-stage startups, all nominated by all the cohosting VC firms.

Join us on June 10th!

@ml_angelopoulos I feel lucky to partner with you and the @arena team. 🙏

[Felicis @felicis]

Two in five home health patients get turned away, not because care isn't available, but because the admin overhead costs more than the agency gets paid.

$40B in referrals are rejected every year. That's the problem @AlexRWendland and Ryan Tolsma are rebuilding from scratch with @joinAdaptive.

AI-native operations. 100K+ visits delivered. 4.9% rehospitalization rate vs. 12.9% state average.

@Felicis investors @Pxd and @EricFlaningam sat down with Alex and Ryan to discuss the future they're building with Adaptive.

[Peter Deng @pxd]

Excited that https://t.co/lVwd3uR1OG can now do a lot more!

[Arena.ai @arena]

Introducing Agent Mode: Agentic AI is now measured in the Arena.

Agent Mode can do deep research, create reports, generate images, build websites, debug code, and more.

It completes more complex tasks by using tools like web search, bash in a sandbox environment, image generation, file writing, and asking follow-up questions.

Frontier models are waiting for you in Agent Mode to take on real-world tasks. GPT-5.5, Claude Opus 4.7, Gemini 3.1 Pro, and top open models. Test them yourself.

@AlexRWendland @ryanatolsma @joinadaptive @49ers 😣

[Peter Deng @pxd]

“How badly do you want this deal?” Ryan, our general counsel, called me while I was at dinner.

Turns out @joinAdaptive redlined the term sheet we sent them to lead their Series A, and they put in a clause that gave me second thoughts.

For context: I’m a die-hard @49ers fan. Beating the Cowboys is always a good feeling. Winning the last 4 games against the Dallas Cowboys including 2 playoff games? The best.

The clause they inserted was a tough one to accept. We ultimately agreed that when the company reaches a significant revenue milestone, @Felicis board members will attend a Cowboys game in Dallas with the founding team… in full Cowboys gear.

Today, over 40% of patients referred to home health don’t get the care they need. Adaptive is using AI to help home health agencies serve more patients, reduce overhead, and expand access to care.

AI has been transforming the digital world, but is only just beginning to change the physical world. Home health is the fastest-growing outpatient sector, on pace to nearly double over the next 5-6 years. The current foundation of fragmented small home health providers is not ready for that influx. Adaptive is rebuilding from the inside out to lay a foundation for an industry positioned to scale.

I’d prefer to keep my 49ers loyalty intact. But if wearing a Cowboys jersey is the price of helping build a company that improves healthcare for millions of people, I’ll survive. To @AlexRWendland, @ryanatolsma, Logan, and Hunter, I’m rooting for you...but not your football team.

[Peter Deng @pxd]

@ryanatolsma @joinadaptive @49ers My hope is that we reach the number quickly and get it over with.

[Felicis @felicis]

Two in every five patients referred to home health care in America never get the care they need.

Not because clinicians aren't available. Not because the patient doesn't qualify. They get turned away because the paperwork costs more than the visit pays. Roughly $40B in referrals get rejected this way every year.

So the agency says no, and the patient ends up in a nursing facility or gets sicker at home until the ER takes over.

We led @joinadaptive's Series A because they stopped trying to sell better software to broken agencies and became the provider instead. AI runs the intake, scheduling, prior authorization, documentation, and billing that traditional agencies burn $.60 to $.90 of every clinical-labor dollar on. When those costs collapse, the patients who would have been rejected instead get the care that they deserve.

So far in Adaptive's first market: Patients served by Adaptive have a 4.9% rehospitalization rate compared to the 12.9% Texas state average and 10.2% national average. More than 95% of patients see improvement in ambulation, meaning they are back on their feet, no longer homebound, compared to an 89.5% national average. Patients are set up with a home care provider extremely quickly, with 99% of patients admitted within 48 hours of referral. They have a 4.5-star CMS quality rating against an industry average of around 3.

Hear from co-founders @AlexRWendland and @ryanatolsma on the future they're building with Adaptive. 👇

Excited to share Adaptive Innovation’s (@joinadaptive) $50M Series A led by @felicis and $10M Seed led by @BainCapVC.

Adaptive is an AI-native healthcare provider rebuilding the way care is delivered in America, starting with home health

1/ Today we're announcing Gigascale Capital's $250M first institutional fund to back early-stage founders rebuilding the physical economy.

[Peter Deng @pxd]

The best part of being at a generalist firm is the freedom to refresh your mental model for where the world is going without being constrained by a predetermined worldview.

The most interesting companies right now don’t fit neatly into a single category. They blur the lines between software, services, infrastructure, consumer behavior, and the physical world.

Today we're publishing the @Felicis Forecast: nine themes we keep coming back to and that keep showing up in the companies we're most excited about.

[Felicis @felicis]

1/ Today we launch the @Felicis Forecast. It's our map of the changes that defy neat categorization but matter most to what’s next. Where AI’s potential cuts across industries to collide with consumer, organizational, and socio-economic fault lines. Where the old structures have ruptured, and new ones are just coming into view.

Because even to people like us – generalists who’ve spent the past 20 years studying change – this moment feels different. Everything’s up for grabs. Rules, tidy bell curves, and comfortable patterns no longer apply.

So instead of following patterns, we forecast: 9 themes we just can’t get out of our heads, that seem to pop up everywhere once you notice them.

@joannejang So true. Those who work for fun are playing infinite games. Infinite gamers generate motivation from within and rarely burn out because the game itself gives them energy.

[Peter Deng @pxd]

@zolotokrylin @HoldexIo They're complementary. When you're operating as if you've already won, the trivial decisions resolve fall away very quickly.

@roeytechai By waiting for consensus, you're outsourcing your conviction. By the time the world agrees you're allowed to do something, someone else with the right mindset has already done it.

@nmasc_ This is the year.

@TBVNetwork Thanks!

@joannejang Best limited-edition sweatshirt I own.
