Hi, I'm Aaron 👋🏻

I'm curious and love to make the ideas in my head real. I've cofounded seven venture-backed startups across enterprise SaaS, healthcare, publishing, consumer apps, and connected hardware.

Today I'm working on Positivesum, a stealth company building at the edge of what's possible. Previously I cofounded Evernow, a telemedicine platform for menopause care, and Doctrly, which automated patient data privacy inside hospitals. I run, bike, and walk my dog in San Francisco.

    A stealth company building at the edge of what’s possible.

    Evernow
    Cofounder

    Cofounded and led engineering at Evernow for five years, building a telemedicine platform for evidence-based menopause and aging care. Backed by NEA and 8VC alongside a remarkable group of investors including Cameron Diaz, Drew Barrymore, Demi Moore, Gwyneth Paltrow, Glennon Doyle, Abby Wambach, and SpaceX COO Gwynne Shotwell. We grew from an idea to a 50+ person team serving thousands of patients a month across the US.

    I built the product end-to-end: a proprietary EHR and customer platform spanning patient intake, provider tooling, pharmacy integrations, subscription management, and mobile experiences. I also scaled the engineering team as we grew. We were at the leading edge of AI in healthcare too, implementing early AI-powered clinical decision support and note-taking just as the technology was making its way to market. Healthcare software is a particular kind of hard: regulatory constraints, real clinical stakes, and patients who need things to work the first time. The experience taught me more about building reliable systems than anything else I’ve done.

    Doctrly
    Cofounder

    How do hospitals manage data privacy internally? Doctrly was an exploration into tools that automatically redact unnecessary personally identifiable information from devices inside the hospital IT ecosystem. Healthcare data breaches are almost always preventable. Doctrly was an attempt to stop them before they happen by making compliance automatic rather than aspirational.
