We partnered with @nvidia to host a demo night at @ideo! 16 startups presented, ranging from agentic AI networks, to US-made drones, and everything in between. If you're an early stage startup focusing on emerging technologies DM me! We'd love to meet you at our next event.

This is such a great way to reduce the need for sequential miracles in product decisions especially for launching new product verticals, expanding to new customer bases, or testing market appetite ✨✨
Today, we’re introducing Tenera: behavioral simulations for product teams. Teams are shipping faster than ever, but product decision making hasn’t caught up. For every big bet, product leaders face the same binary choice: ship on instinct, or wait weeks for validation. Tenera predicts how users will react to software before it ships. We train a dedicated model per persona, grounded in customer evidence and behavioral data, so predictions reflect how your specific users behave, not a generic average. It helps teams prioritize, pressure test, and validate high-stakes product decisions - faster and at scale. The winners won’t be the teams that build the most. They’ll be the teams that know what to build first. Book a demo ↓ trytenera.ai

Typos and weird emoticons will no longer be an “unprofessional faux pas”, as they will be evidence of no AI involvement. And we wiLL bE fRee tO type hoWever we WANT! :D ~ sent from my ipad

hot take, the importance of brand and design is not a hot take 🥲

Building Digital Me by cross referencing 150+ biomarkers @sonatahealth, historical health data (tests, prescriptions, after visit summaries), items in my fridge, @ouraring data, my workouts, therapy notes, my journal, at-home sleep test, and recorded calls with my psychic

Currently very inspired by hand painted screens~ 18th century Venetian and French Renaissance @1stDibs (can use as: room divider, headboard, wall art, hang towels or clothes on.. the list goes on and on)

What if modern medicine felt like a work of art? Today @sonatahealth is live in NYC, SF, and LA, and we couldn't be prouder to have helped bring it into the world. Sonata maps your whole genome, hundreds of biomarkers, your cellular age, and then puts a real care team on top of the whole picture. Healthcare built for your biology, actually yours. When the founder, @SaganSchultz first walked us through his vision of concierge medicine, genomics, biomarkers, and contextual intelligence woven into one experience, we knew right away we wanted to make something harmonious, artful, and calm; a brand you'd trust with your body. A ‘sonata’ is a musical form built on structure: distinct movements, precise notation, played with feeling. That felt like everything care should be; mathematical underneath, human on the surface. We knew this name was perfect. Visually, we rendered a calla lily 🌷in cross-processed colors of petal blues, sunset corals, and an iridescent wash to give the data-heavy brand room to breathe in airy, open spaces. Then we built the counterpoints of exacting copy, fine atomic details of UI, data charts, and user flows. The elegant wordmark paired against against a living flower felt like the right balance. We carried that discipline into motion and the product itself. The flower breathes rather than spins. Interfaces settle with an unhurried weight.  The user flows follow the same logic: one step at a time, plain language, your results building into a picture as you go, a doctor visible at the end of every decision. We treated movement and flow as clinical trust signals: a system this confident doesn't need to shout. All of it is tuned to one job, helping you be present with your body's information. We aimed to make a new medicine brand that felt modern and timeless at once.  ~ @littleplainsxo helped create the naming, brand strategy, positioning, verbal system, visual identity, motion design, and product surfaces where the science becomes care. Grateful to Sagan, David, Hiya, Dev, and the @sonatahealth team for the trust. Your health story begins today. 🌸

AI was literally built for generalist sidequesters. In the entire time my website and images have been generating I've cleaned my room, read a book, made pancakes, and learned a song on the omnichord.

Excited to share that @sonatahealth is emerging from stealth today, and proud that @Lux_Capital is unveiling our investment. What impressed us from day one wasn’t just the product. It was the team. @SaganSchultz (physician + early product at @Linear) and David (Flatiron clinical genomics + early engineer at @tryramp) bring together medicine, product, and engineering in exactly the right way for this moment. SONATA is building preventive healthcare for the AI era: combining deep biological testing, longitudinal physician relationships, and clinical AI to help people stay healthier, longer. If you know me, you know I’m especially excited about what they’re building for women’s health, where longitudinal, context-aware care has the potential to be truly transformative. If you’re in NYC, SF, or LA and want to take a more proactive approach to your health, I highly recommend checking them out: sonata.health Congrats to the entire SONATA team. And a fun one to tag-team with my partner @lanjiang653 . 🚀

Today we're launching SONATA (@sonatahealth) , a doctor-led healthcare membership focused on preventing disease before it starts, backed by $7M from @Lux_Capital, @BoxGroup, @seedtosunflower the founders of @tryramp and @linear, and other angels and operators. I spent nearly a decade working in NYC restaurants through college, med school, and business school. Danny Meyer built that world on one idea, anticipating what someone needs before they ask. Every day I'd walk into the hospital and watch medicine do the opposite. Wait for disease, react to crisis, move on. I could never reconcile the two worlds. At Linear, we made the same bet, that people can feel craft. They can. Somehow that thinking has reached almost every industry except the one that matters most. I can't unsee it. Most people I know are already working hard on their health. They track their sleep, their training, their biomarkers. They read the studies. Their data is a thousand times richer than anything their doctor will ever see. They're trying to stay ahead of the problems they watched their parents face, willing to try almost anything. The system was never built to meet them there, so they've taken it on themselves. Interpreting their own labs, coordinating specialists who don't talk to each other, asking ChatGPT to make sense of it all. It's become a second job, and an exhausting one. We're trusting less than ever, spending more than ever, and we're still not well. SONATA is the version of care I couldn't find. Board-certified physicians who go deep into your whole biology, your genome, your biomarkers, how you're actually aging, and then stay with you over time. Behind them, clinical AI we built to connect the dots across all of it, surfacing patterns that would otherwise go unseen. Not a dashboard of endless vanity metrics, and not a set of recommendations you're left to execute alone. A care team that knows you deeply, anticipates what you need, and carries the complexity so you don't have to. Care that compounds. We are live in NYC, SF, and LA. You can learn more at sonata.health.

I was diagnosed with cancer in my 20s after finding a genetic variant. Without that, I'd have gone years undiagnosed. Longevity starts with knowing your own biology and tailoring care to it. I'm a big fan (& paying customer) of @sonatahealth. Comment/DM if you want to hear more x
SONATA is rebuilding concierge care for the AI era. Every member gets deep testing, a personalized care plan, and a doctor who walks them through it. AI is built into the workflow, so doctors spend more time on high quality care. Join now at sonata.health
