How much did 37signals actually save by leaving the cloud - and does that math apply to mid-market companies?
CTOs and CFOs evaluating whether the most-cited cloud-exit case applies to them.
The short answer
By its own published figures: a $3.2M annual cloud bill, about $700K in servers recouped within a year, roughly $2M/year in savings, and a projected total bill well under $1M after a full exit. The caveats are the transferable part: self-reported by a vocal advocate, built on stable workloads, and backed by a strong in-house ops team.
What informs this answer
Selected results from related operator-led engagements, by industry and scale:
- 28,000-user migration with zero downtime
What to ask next
What preconditions made the 37signals exit work?
Stable, deeply understood workloads; spend material enough to justify ownership; and an operations team capable of running hardware. Companies missing any of the three usually do better with optimization or a partial move.
Do the giant repatriation numbers - like Dropbox's - apply to mid-market companies?
Directionally instructive, directly no. Dropbox reported nearly $75M saved over two years in its SEC filing, but that reflects hyperscale storage economics. Below that scale, ops staffing fixed costs dominate and the math must be rebuilt per company.
