About Brittany Sigler, MPH, DrPH

I believe the biggest lever for improving population health isn't inside the healthcare system — it's upstream, in the consumer products people actually use every day. My work sits at the intersection of consumer experience and clinical credibility, helping health tech teams build products that change real-world behavior and hold up under scrutiny.

What I've built

Over 12+ years, I've led product across startups, government, enterprise, and academia:

• CVS Health/Aetna: Led Attain, the Apple × Aetna wearables product, scaling it to 13M members with 68% year-over-year revenue growth. Directed product strategy across ActiveHealth's consumer engagement suite.

• NYC Department of Health: Built digital mental health tools for one of the largest public health agencies in the country.

• Startups: Fractional product leadership for Seed–Series B health tech companies navigating product-market fit, evidence strategy, and commercialization.

• Academia: DrPH from Johns Hopkins, MPH from Columbia Mailman. My doctoral research focused on leveraging consumer technology as an upstream intervention for population health, and how to get investor buy-in to this thesis.

How I work

I embed with your team — typically as a fractional product lead — and operate like an insider, not an outside advisor. I bring product strategy, UX research, market research, and data science tooling (ML, NLP, GenAI) together to make decisions that are evidence-backed, not gut-driven. I've led cross-functional teams from 5 to 100+ across engineering, design, product, and go-to-market — and I work in phases with clear deliverables, so you always know what you're getting and when.
