Our Heroku bill was about to clear $130K annual and we had a Series-B narrative to land. The CTO had quoted us 4 engineering months for a self-run migration; nobody had those months. We'd talked to one Big-3 consultancy and bounced — they wanted $180K minimum to start.
Routed to a Frankfurt-based Advanced partner with SaaS migration specialty and existing EU-region builds.
Production cutover at week 9. ECS Fargate + Aurora Postgres + multi-AZ. AWS funded the engagement under MAP — we paid the partner $0 for delivery. Heroku bill went to $0 by month 2. New AWS run-rate landed 62% below Heroku, with $80K of base credits absorbing the first 9 months.
“I budgeted 4 engineering months for this and gave up 6 hours total. The partner did the work, AWS paid for it, our bill dropped. I keep waiting for the catch.
