Episode notes
Benchmark Identity With A POC
- Always run a POC to benchmark identity providers against a truth set like logged-in users or customer databases.
- Reject vendors that fail your match-rate benchmarks during the POC.
Scale And Network Effects Matter Most
- Global footprint and match rates drive competitive advantage more than selling a single method.
- Network effects make a small set of IDs valuable because publishers and buyers need common currency.
Acquisition Grew ID5 30–40%
- The TrueData acquisition increased ID5 headcount and revenue by roughly 30–40%.
- Mathieu described an intense transatlantic diligence with multiple law firms and months of work.
