Meet Our Latest Batch of Startups: Cohort 22-1

Why 22-1? Historically, our cohorts were named for the year’s peak atmospheric carbon dioxide concentration (in parts per million [ppm]), based on the Keeling Curve.

We're a bunch of science nerds at D3, but we realized this was just a little too wonky—so we’re switching our cohort names to represent the year and quarter of their launch.
