Backed @tienlan_sun early at Foresight Health and posts like this are why. The thesis is right: prevention beats treatment, but it's been bottlenecked by clinician hours. Pairing licensed care infrastructure with agents that actually learn from outcomes is the unlock. Proud to be partnering with @tienlan_sun for this ambitious build!
Congrats to @RichardSocher and the @Recursive_SI team on emerging from stealth.
As an investor, I’m thrilled to be a small part of the journey alongside @RichardSocher, @_rockt, @timshi_ai, @josh_tobin_, @CaimingXiong, @jeffclune, @tydsh, and Alexey Dosovitskiy.
Recursive is pursuing one of the most ambitious ideas in AI: recursive self-improving intelligence that can automate knowledge discovery.
If they succeed, we could move from AI systems that help us reason about known problems to systems that continuously generate, test, and refine new ideas, accelerating scientific discovery itself.
The ambition is enormous, but so is the team. Excited for what’s ahead!
The biggest risk in AI is not the failure you catch. It is the one you never see.
A review of hundreds of thousands of real AI conversations by @mmooritz and @ChrisGPotts from @stanfordnlp found that 78% of failures are invisible — no complaint, no escalation, no obvious signal.
This is a problem.
In this piece, I shed light on what this means for teams deploying AI in the real world and how they can address it.
Congratulations @alexmashrabov and the team at @higgsfield_ai on surpassing a $200M run rate in under nine months—faster than any GenAI company we’ve tracked! It’s been a privilege to be part of this journey with you from the very beginning as an investor, and I couldn’t be more excited to watch you continue redefining the future of video production.
Higgsfield is officially the fastest-scaling GenAI company in history, doubling from $100M to $200M in just 2 months.
$200M annual run rate in under 9 months.
We have raised a $130M in Series A at a $1.3B valuation, backed by Accel,
AI Capital Partners (Alpha Intelligence Capital's US-based fund), and Menlo Ventures.
To the creators and partners who built this with us: thank you for making Higgsfield a global movement.

[ SUPERPOWER'S VISION ]
The human story is a story of progress.
And while every system and institution has been accelerated by technology and AI...
We forgot human health itself.
Somewhere along the way, the health system became about treating sickness rather than improving life.
So we asked –
How might we build a new system for health?
There are a few parts.
A new health system will:
1. Be the front door – before doctors or Google
2. Prevent disease & enhance human capability
3. Deliver care via AI
4. Feel more like Apple or Tesla than a hospital
5. Put power into the hands of people
6. Lower costs, in line with physics not incentives
7. Bring frontier therapeutics to everyone, far faster
Within this new system, our lives begin to improve.
Health becomes a tool that helps us be happier, more energetic, smarter, fitter, more vibrant, and live longer.
HOW DO WE GET THERE?
Our three-step plan:
STEP 1 — deliver the world’s best lab testing
STEP 2 — build the full action layer (protocol, RX, supplements)
STEP 3 — use a self-learning healthcare system to create a superior model of medicine
INTRODUCING SUPERPOWER
Superpower is your home for health.
We give you the best tests, protocols, therapeutics, peptides, and AI.
You tell us your goals, preferences, budget, health history; we tell you what to do. We test your body, aggregate your data, and build a protocol to put your health on autopilot.
Practically, we give you:
+ Blood draws
+ Biological age
+ N of 1 protocols
+ Health records storage
+ Personalized supplements
+ Advanced therapies
+ GLP-1s & peptides
+ RX prescriptions
+ Cancer testing
+ Toxin testing
+ Gut testing
+ And more
93% of our members say we're better than their doctor or life changing.
Our goal is to help you feel great. You should look younger, have more energy, sleep better, and live longer.
We remove the thinking. We provide the system. Health finally becomes easy. In time, the system will know what you should do better than any doctor, concierge, or human on the planet.
How?
In the process, we build a digital twin of your health that improves with time so that we can move towards a new, superior model of medicine.
We create a learning healthcare system, which takes us to the final step of our three-step plan (more on that soon).
WHAT'S NEXT
This is the start of multi-decade journey. We aren’t done until the human health is transformed for the better.
Over the coming weeks, I’m going to be sharing weekly shipping updates to show how we’re achieving this vision.
Follow along!

Big congrats to @function on a successful fundraise — love seeing the category grow. 👏🏿
My bet is on @superpower because:
- One blood draw at 3,000+ labs or home phlebotomy
- Advanced and actionable insights + digital twin
- Real medical team + smart AI 24/7 to guide change
- Personalized protocols + Rx + peptides
- 3x more value for nearly ½ the price
I think it is critically important that we all become more proactive around our health. Testing is step one. Action is what changes health. 💪🏿
Congrats on the fundraise Function. In case you're wondering, here's how @superpower sets itself apart (tl;dr we do 3x more for half the price) 🧵

👏 Huge congrats to @superpower for making health more accessible than ever.
For just $199, you get testing, records, an AI health guide, and a medical team in one place.
There’s no better ROI than investing in your health — and now there’s no excuse not to. 🚀
BREAKING:
Superpower is now available for only $199
almost every American spends a few hundred $ per year on things like:
– Netflix
– Spotify
– Amazon Prime
– Dating or meditation apps
– Annual credit card fees
and never thinks twice.
but there has never been an accessibly priced,
canonical consumer membership for the most important thing of all:
YOUR HEALTH.
it’s our goal to build the most valuable, lowest price health membership in America.
and now it’s never been simpler to get started:
– full body health testing (100+ labs annually)
– one home for all of your health records, unified in one place
– a personal health LLM to chat with and make sense of it all
– plus a human medical team + marketplace for anything you need, like prescriptions, supplements, tests, or health answers – all at 20% cheaper than elsewhere
all for only $199.
it pays for itself. it’s taking control of your health.
“But Jacob — I have a bit more budget to spend on my health, this feels too cheap”
feedback we get often.
however it’s our belief the greatest consumer companies are built with low floors ⬇️ and high ceilings ⬆️;
accessible enough to welcome anyone in, yet expansive enough to grow with those who want to invest more deeply.
(eg. almost every American has an Amazon account, half of which pay ~$200/yr for prime, and 30% of which account for 70% of sales. our top superpower member has already spent over $30k on their health within the ecosystem)
this moment has been a long time coming
and couldn’t be more thrilled to unveil it to the world alongside such an incredible team.
ps – we’ve also just launched the mobile app, DM if you’d like the test flight!

Consumer AI is the next frontier.
Come see what’s next on June 26th in SF. ↓
Congrats @KianSadeghi5 and the team at @nucleusgenomics! It is incredible to witness the convergence of AI, genomics, and ambition in real time. The frontier of longevity isn’t just lifespan — it’s pre-life design.
Longevity is now for embryos.
Nucleus Embryo is the first-ever genetic optimization software that helps parents give their children the best possible start in life — long before they’re even born.
Longevity was never just about health. It’s about thriving.
That’s why this announcement also marks the first time in human history a company has openly partnered with a couple to help them optimize their embryos based on intelligence.
Big congrats to the @RilletHQ team on the $25M Series A! We backed them at the seed because we believed in the vision—and the grit. ERP isn’t a “move fast” category, but they built patiently, listened deeply, and earned every bit of this momentum. Onward. 👊🏿
This quoted post is unavailable.
Big congrats to @superpower on launching The Founder Health Coalition!
As a previous founder and operator, I’ve felt the highs of building—and the quiet toll it can take on your health. This movement is a reminder: we don’t have to trade our well-being to build something great.

Today, we are launching the first publicly available AI Scientist, via the FutureHouse Platform.
Our AI Scientist agents can perform a wide variety of scientific tasks better than humans. By chaining them together, we've already started to discover new biology really fast. With the platform, we are bringing these capabilities to the wider community. Watch our long-form video, in the comments below, to learn more about how the platform works and how you can use it to make new discoveries, and go to our website or see the comments below to access the platform.
We are releasing three superhuman AI Scientist agents today, each with their own specialization:
A general-purpose agent (Crow);
An agent to automate literature reviews (Falcon); and
An agent to answer the question “Has anyone done X before” (Owl).
We are also releasing an experimental agent, Phoenix, that has access to a wide variety of tools for planning experiments in chemistry. More on that below.
The three literature search agents (Crow, Falcon, and Owl) have benchmarked superhuman performance. They also have access to a large corpus of full scientific texts, which means that you can ask them more detailed questions about experimental protocols and study limitations that general-purpose web search agents, which usually only have access to abstracts, might miss. Our agents also use a variety of factors to distinguish source quality, so that they don’t end up relying on low-quality papers or pop-science sources. Finally, and critically, we have an API, which is intended to allow researchers to integrate our agents into their workflows.
Phoenix is an experimental project we put together recently just to demonstrate what can happen if you give the agents access to lots of scientific tools. It is not better than humans at planning experiments yet, and it makes a lot more mistakes than Crow, Falcon, or Owl. We want to see all the ways you can break it!
The agents we are releasing today cannot yet do all (or even most!) aspects of scientific research autonomously. However, as we show in the video, you can already use them to generate and evaluate new hypotheses and plan new experiments way faster than before. Internally, we also have dedicated agents for data analysis, hypothesis generation, protein engineering, and more, and we plan to launch these on the platform in the coming months as well. Within a year or two, it is easy to imagine that the vast majority of desk work that scientists do today will be accelerated with the help of AI agents like the ones we are releasing today.
The platform is currently free-to-use. Over time, depending on how people use it, we may implement pricing plans. If you want higher rate limits, especially for research projects, get in touch. @m_skarlinski, @andrewwhite01, @_tnadolski, Remo Storni, @semajazarb, @ludomitch, @MichaelaThinks, as well as @jasonjoyride and his team for making such fantastic videos of us!
