Interim CTO at PE-backed B2B SaaS company (Keensight Capital, prev.

Results: ✓ Tech Due Diligence report delivered to PE fund ✓ Cloud transformation roadmap (Azure/AWS) board-approved ✓ M&A integration completed – systems consolidated ✓ IT costs optimised, security governance established Insights: → Post-acquisition B2B SaaS requires immediate transparency on tech debt and cloud costs – investors need reliable numbers, not roadmap promises. → Multi-cloud consolidation is not a purely technical project. Without clear ownership and business alignment, every migration becomes a never-ending project. → M&A integration only succeeds when you stabilise and transform simultaneously – sequential approaches lose momentum and trust.
