For YC founders
If you're 14 weeks into batch and your Oura score is a disaster…

A doctor that reads your entire chart in the thirty seconds between customer interviews.

An AI primary care doctor that auto-syncs 150,000+ record sources and reads your labs and wearables together. Built for founders who won't get a PCP this quarter.

Get started The batch timeline

"My Oura score has been a mess since batch started. Haven't seen a doctor in 4 years. Problem?"

Founder, ~week 11asking Clara

"Booking an SF PCP is a 4-month wait. Is the chest tightness on runs worth worrying about?"

Founder, ~week 9asking Clara

There is a pattern. You get into YC. You move cities. Your PCP is in your old city, or they were never a real PCP to begin with — they were the person you saw once when you thought you had mono in college. You tell yourself you'll sort it out after demo day. You do not sort it out after demo day.

"The only person who sees my medical data regularly is my wearable."

Meanwhile the 16-week batch compresses a normal year of founder stress into four months. Sleep craters. Caffeine triples. You develop the GERD. You notice your resting HR on Oura has drifted up by 12 bpm in a quarter. You Google things you should be asking a doctor and find ten conflicting Reddit threads. The YC alumni group chat becomes your peer-reviewed journal.

Clara is for that. Not because founders are a special medical category — they aren't — but because the format of modern primary care doesn't fit a founder's life at all. You can't take Tuesday afternoon off for a 15-minute visit that will involve the doctor reading your chart for the first time in the exam room. You can message a doctor who can actually see your data, and get a substantive answer in the gaps between your other work.

The batch timeline

When YC founders actually message a doctor.

Batch week 1–4

"My sleep is tanking. I can't tell if it's caffeine or something real."

Clara reads your wearable baseline against your last lipid and thyroid panel, correlates resting HR with HRV and sleep-stage data, and tells you whether the signal is "stress + caffeine" (most common) or something that warrants a workup. If it's workup-worthy, Clara drafts the labs.

WearablesSleep
Batch week 5–9

"Acid reflux. And this headache that's been there for a week. And I think I need a UTI script by tomorrow."

Acute founder medicine. Clara handles GERD, UTIs, sinus infections, headaches — takes intake in chat, sends the script to the pharmacy nearest your co-working space. No urgent-care trip in the middle of customer-interview week.

AcutePrescriptions
Batch week 10–14 · demo day run-up

"My resting HR has been elevated for 3 weeks. I have dress rehearsal Friday."

The pre-demo-day stress physiology shows up in Oura, Whoop, and Garmin data weeks before it shows up in the exam room. Clara cross-reads chart + wearable to surface pattern-level signals: sympathetic overload vs. thyroid drift vs. cardiac. If the answer is "this is stress," it says so. If not, Clara drafts the ECG + hs-troponin + TSH order.

CardiometabolicWearables
Post-demo day · the crash

"Everyone gets sick the week after demo day. I also want my labs checked."

Post-demo-day labs land here. Clara orders a lipid panel, TSH, A1C, and CBC (Standard and Concierge plans include 74 and 108 biomarker tests in the membership, bundled — no separate lab bill, not billed to insurance). See longevity labs. If something's off, Clara drafts the plan.

LabsPreventive
Seed round through Series A

"My LDL was 158 three years ago. I don't know what it is now."

Clara pulls every lipid panel you've had in the past decade from your prior PCPs into one trend. If ApoB is drawn, it's included in the picture. Drafts a plan — lifestyle first, atorvastatin if warranted — with an 8-week recheck on the calendar. Prescriptions are reviewed and approved by a licensed physician before they leave.

Batch will be over in 12 weeks. Your labs will still be 4 years old.

The work a 15-minute primary care visit was never structured to do.

YC founders aren't unusually hard to treat. What is unusual is the combination of data they produce — continuous wearable streams, scattered prior records across three cities, a schedule that won't accommodate a 45-minute in-person visit, and a density of questions a 15-minute visit literally can't answer.

Full-chart reasoning every turn

Can your old doctor read your entire chart, your wearable trajectory, and every lab you've had drawn across three cities, every time you ask them something? Clara does — in seconds. That's a category-of-work difference, not a time-management difference.

Cross-reads your wearables

Your Oura resting HR trajectory and your last lipid panel live in one reasoning pass. Clara reads them together — with prior meds and a 3-year visit history as context — and either reassures you with signal or escalates with a real plan.

Continuity the schedule can't break

Clara remembers the 8-week ApoB recheck, the 2-week stress-pattern follow-up, and the next-due screening, and pings you in the chat when they come due — whether you're in SF, on a red-eye, or at the YC summit.

Your chart, your wearable, your question, answered instantly.

YC founder FAQ

The questions founders ask before clicking "get started."

Is Clara affiliated with Y Combinator?
Clara is independent of Y Combinator. No endorsement by YC, its partners, or its portfolio is implied. This page is written for founders because YC founders are one of the groups where the mismatch between the 15-minute-visit format of modern primary care and the actual shape of a founder's schedule and data is largest.
Is this primary care, or a triage bot?
It's primary care. Clara's AI does the clinical reasoning end-to-end. Clara manages chronic conditions (hypertension, cholesterol, type 2 diabetes, thyroid, GERD, asthma), handles acute issues (UTIs, URIs), and orders labs. It replaces the 15-minute visit, not the specialist.
I moved to SF from another city and don't have a PCP here. Is Clara a real substitute?
Yes, for what a PCP does in the 15-minute visit format — chronic-condition management, acute low-to-mid-acuity issues, lab ordering, prescription writing, preventive-care tracking. Clara operates through affiliated professional corporations licensed in all 50 states, so the prescribing and lab ordering carries over when you travel. Clara refers you out to a specialist or in-person clinic when a physical exam, imaging, or procedure is required.
How is this different from One Medical?
One Medical is $199/year plus visits billed to your insurance. The substantive work happens in scheduled visits; the on-demand surfaces are wait-gated. Clara inverts the format: the substantive work happens in the AI chat, instantly. Clara's membership is cash-pay, HSA/FSA-eligible, not billed to insurance; what may be covered by your insurance are the prescriptions Clara writes and ad-hoc labs Clara orders. See the full comparison on Clara's AI primary care page.
What does Clara cost?
Free to connect records and chat. Paid plans: $25/month Basic, $50/month Standard (adds wearable integration and 74 biomarker tests included in the plan), $150/month Concierge (108 biomarker tests, unlimited messaging with the medical team). All plans HSA/FSA eligible. Biomarker panels on Standard and Concierge are included in the membership — not billed separately, not billed to insurance. Prescriptions Clara writes and ad-hoc labs Clara orders may be covered by your insurance at your pharmacy or at Labcorp/Quest.
Can Clara prescribe GLP-1s?
Yes — FDA-approved branded GLP-1 medications (Ozempic, Wegovy, Mounjaro, Zepbound) where clinically appropriate. Not compounded formulations. These may be covered by your insurance at the pharmacy.
Is Clara a real medical practice?
Yes. Clara operates through affiliated professional corporations licensed in all 50 states. A licensed physician reviews and signs off on diagnoses, prescriptions, and lab orders. Clara's AI handles the intake, clinical reasoning, longitudinal tracking, and follow-up.
What is my data used for? Is it private?
Clara is HIPAA compliant. Your records are used to personalize your care. They are not sold and not used to train public AI models.
