How we work

A mission that actually pulls people in

We make the microbiome measurable and actionable at every life stage, and real people write in to say it's life-changing.

Remote-first, real overlap

Our FTEs are based in North America and work core hours from 9am–6pm CST, shiftable by up to two hours either way — start at 7am or 11am, wrap at 4pm or 8pm.

Written first, huddle second, meet last

Default to a clear Slack post, huddle when a thread stalls, and meet only to make a real decision.

Fast, but never sloppy

Do the two-month thing in two weeks, then check the work—shipping errors is rework, not speed.

Shape what we build, not just how we build it

There's no playbook waiting for you, so write it—and bring the alternative, not just the objection.

Day One mentality

Fewer titles and layers; process is a guardrail where it counts, never the reason something didn't ship.
