I ve been thinking about the tension between single-player mode and multiplayer mode in SaaS (especially in the days of LLMs & user context).

On one hand, founders (myself included) often hear: Don t just build for one user, build for teams. That s where the revenue and moats are.

Everywhere else I look podcasts, social media, even casual discussions  longevity is a hot topic. Bryan Johnson, for example, shows up in my feed constantly.

For me, health-tech feels like the most valuable thing we could be building. Not just extending life expectancy, but actually improving quality of life.
