How Trapped Are You By Your Vendors?

Vendor lock-in is invisible until it becomes expensive. A 40% price increase when you have no exit plan means you pay it. A vendor acquisition that changes your product roadmap means you scramble.

Most teams evaluate vendors before signing but never assess lock-in risk during the relationship. By the time they need to leave, migration costs have grown 5-10x what they would have been with proactive abstraction.

Questions CTOs ask

How do you assess vendor lock-in risk?
Evaluate lock-in across six dimensions: data portability (can you export in standard formats), API dependency (proprietary vs standard interfaces), feature exclusivity (vendor-specific capabilities you rely on), switching cost (migration effort estimate), alternatives availability (viable competitors), and knowledge lock-in (team expertise specific to this vendor). Score each 1-5 and weight by annual spend to calculate risk exposure. This tool flags a vendor as high risk above 65/100, and critical above 80/100 when exit readiness is below 30 — those are the ones that warrant exit planning now rather than at renewal.
When should you start planning a vendor exit?
Start exit planning proactively — before you need it. Key triggers include: price increases exceeding 20%, repeated service degradation, vendor acquisition by a competitor, contract renewal approaching within 12 months, or identifying a significantly better alternative. The best practice is to maintain abstraction layers around critical vendors from day one and review lock-in risk quarterly. The cost of planning an exit you never use is negligible compared to the cost of an emergency migration.
