Premium flex in San Francisco runs around $1,280/seat/month — the breakeven against a traditional 7-year Class A lease typically lands between 30 and 50 seats over a 3-year horizon.
Flex per-seat-month aggregates to a 3-year cost of $46,080 per seat. Equivalent lease economics are the sum of base rent + opex + amortised fit-out">fit-out. The Lease vs Flex Comparator runs both at the same horizon.
Short horizons (under 24 months), uncertain headcount trajectory, satellite or project-based teams, requirement under 30 seats. Flex also wins on optionality — month-to-month exits versus a 10-year termination negotiation.
Long horizons (5+ years), stable headcount, brand requirement, hardware-heavy team, or any requirement above ~50 seats in a market with active landlord competition.
