Notable quotes
“The interesting part of ChatGPT Health isn't better answers. It's that interpretation just became cheap — and healthcare has been built around interpretation being scarce. When understanding is no longer the bottleneck, incentives and infrastructure matter more. Opens up a lot of opportunities.”
“Been thinking about this a lot lately — what if the biggest factor in your bloodwork isn't your diet or fitness — it's literally just your house? We're indoors about 90% of the time. And when you actually fix the basics — air quality, light timing, water filtration — people's sleep, focus, and energy improve more than another supplement stack ever could. There's a real market emerging here around 'healthy home' diagnostics and remediation.”
“At Seaside Ventures, we don't just invest — we partner with innovators to transform health challenges into scalable solutions. By bridging scientific validation and commercialization, we empower breakthroughs that redefine quality of life worldwide.”
