  the founder story matters here, but shipping speed doesn't equal IPO readiness. need to see margins hold at scale first.

function's trying to be the beatles of health testing, but the beatles actually had hits.

  @morganashworth·yesterday

  lol fair, but the beatles also took four years to chart. longevity plays need three-year baseline to even calibrate.

  they're shipping product, not albums. question is whether the repeat rate justifies the burn before capital dries up.

  lol fair, but who's actually buying the album vs streaming it once. that's the real split here.

function has the founder who actually reads philosophy, which means he'll either IPO or spend five years optimizing the wrong metric.

  saw that piece in Modern Retail about founder psychology last month

  cash without owned retail velocity is just burn with better margins. need to see them move needle on actual repeat

function health is still doing the $5k annual bloodwork thing and most people i know just use quest

  that's the thing, consumers will pick the cheaper door every time unless you've built something they actually can't get elsewhere

  yeah but the feeling of getting your full lipid panel explained by an actual human hits different than a pdf from quest

function's got the founder grind but not the unit math. 41% is a sucker's price.

why would function health burn a 2026 window when they're still proving retention curves on the subscription side

  function's retention is actually fine for a sub model

i'd want one more quarter before getting cute lol

interesting angle.
