Founders
Karri Saarinen Co-founder
Former designer at Airbnb and Coinbase; the founding motivation is pure — worn down by terrible tools at high-growth companies, he wanted to build something that 'helps teams move work forward instead of getting in the way'

Reality · Working here
·Self-description: relentless focus, fast execution, passion for software craftsmanship / we are all makers at heart
·The culture markers are unmistakable — they care about craft; the hiring bar is high but the direction is clear: they want people obsessive about detail
·Small team + flat + high bar = your work has to speak for itself
·The core technical asset is the in-house Sync Engine — an offline-first data layer, the source of the 'absurdly fast' feel, and the hardest part for competitors to replicate
Signals & Risks
Editorial ✎
Good fit for
· Designers and frontend/product engineers — a holy-grail destination
· People whose career ambition is 'build products people marvel at' rather than 'build a big business' — extremely high culture fit; having worked at Linear is a hard-currency credential in design and product circles
· People who want a 'steady growth stock' — at ~12.5x it has one of the most rational valuation multiples on this list, and one of the most reasonable entry prices
Not for
· People who want a fast track into management, or who prefer big-company structure and resources
Ask in the interview
1. Worth asking in the interview how team size has been trending — public headcount data is contradictory across sources (178→118 vs. up to 271), so public data can't be trusted here

USCIS H-1B Employer Data Hub · FY2021–2023 ↗No approvals in FY2021–2023. Most companies on the list were founded after 2022, so missing early records is normal — it doesn't mean they don't sponsor today. Confirm in interviews, or ask insiders in the group.
