TL;DR
- Flex wins below 30 seats, under 18-month horizon, in any major market.
- Traditional lease wins above 75 seats with a 5-year+ horizon — the breakeven is consistent across markets.
- Mixed strategies (HQ lease + flex satellites) increasingly dominate enterprise occupiers.
- Use the Atlas's Lease vs Flex tool to model the breakeven for your specific city and headcount.
When flex wins
Flex providers (WeWork, IWG, Industrious, The Office Group) are structurally cheaper at small headcounts and short horizons. The flex per-seat-month price embeds the landlord's lease, the build-out, the furniture, the tech, and the management — all without the upfront capital. For 10 seats over 12 months, flex is rarely beaten. Flex also wins on optionality: scaling up or down within 30-90 days is impossible on a traditional lease and trivial on a flex contract.
When a traditional lease wins
Above ~75 seats and ~5 years, the per-seat-month economics flip materially in favour of a direct lease. The amortised fit-out">fit-out and lower per-foot rent overwhelm the flex provider's margin. A traditional lease also gives the tenant the right to brand and customise — flex floors are by definition standardised. For tenants whose office is part of recruiting and culture, this matters.
The mixed strategy
The dominant enterprise pattern in 2026 is HQ on a traditional lease + satellite presence on flex. The HQ captures the per-foot economics; the satellites capture the optionality. Companies in growth markets (India, the Gulf, Southeast Asia) often run flex-only for 12-24 months before signing direct leases.
