AI to Power the Healthcare Revolution

1 in 31 kids has autism.

In today's system, the path to a genetic answer takes years.

With Sunstone's AI, it's 12 weeks.

$1M left to close our Series A. $8.5M valuation set by Saturn Partners. 6.5M+ lives in our pipeline. Pilots live now.

What we do.

We end the diagnostic odyssey — years of wrong specialists, wrong tests, and wrong treatment. It's the single biggest cost sink in genetic disease.

How we do it.

We sell self-insured employers a benefit for their employees' families.

Our AI finds the kids in the claims data. Broad Clinical Labs sequences their genome. Our doctors deliver a plan to their doctor.

12 weeks, end to end. Not 7 years.

Why autism is broken.

1 in 31 kids. ABA therapy costs employers $40K–$60K per child per year.

Autism is deeply genetic. About 30% of cases have an identifiable genetic cause today, and that number grows every year as the science improves. But fewer than 20% of kids with autism ever get a genetic test — even though every major pediatric board recommends it.

So therapy gets built on guesswork. A child gets the wrong care for years. One undiagnosed case can cost $3.1M over a lifetime.

The kids are in the data. Nobody is looking.

Christopher. Age 7.

Before Sunstone: 40 hours of therapy a week. No plan. No genetic test. $58,400/year.

After Sunstone: Fragile X found. Therapy rebuilt around it. Real progress in 6 months. $21,200/year.

64% less money. A child with a plan. A family with answers.

How we make money.

$10,000 per case we solve. Flat fee. Paid only after we deliver the doctor-to-doctor care plan.

One case that breaches a $250K stop-loss = 25× ROI. And the employee gets something priceless: real answers for their kid.

60%+ gross margin at scale.

Autism today. Every genetic disease tomorrow.

We start with autism — the pain is real, the market is big, the genetics are clear.

Then: pediatric epilepsy. Rare disease. Adult genetic conditions. The identification layer we build for autism becomes the layer for every genetic disease in employer health plans.

Where we are.

1. 6.5M+ lives in active pipeline
2. Fortune 50 telecom — NDA signed, principal benefits buyer
3. National grocery chain — pilot exploration
4. Care management platform — 200K lives, contract finalization
5. Broad Clinical Labs — signed lab deal with the institution behind the Human Genome Project
6. Advisors from Mass General Brigham, Medco, Illumina, Proteus, Alva10

We have contracts on the table.

Why I built this.

I'm Joshua. Biomedical engineer, Harvard-trained. My son has PFAPA — a rare autoimmune condition with no treatment.

I know what the system does to families who don't fit its script. I lived it.

So I built what we all needed.

The round.

Why community.

We could have closed this with institutions. We chose you.

Because the people who understand why Sunstone matters are the ones who've lived it. Parents. Clinicians. Benefits pros. Anyone who's watched the system fail a kid.

We want you in. Not for the check. For the army.
