Estimated — public data is not fully disclosed.
- Concentrated focus on B2B enterprise categories rather than broad generalist investing
- High scrutiny on retention, payback, and ICP clarity even at early stages
- Preference for domain-expert founders with credible enterprise buyer access
- Diligence often includes real market validation through the CXO Advisory Board
Sierra is accessible to strong early-stage founders and regularly writes first institutional checks, but its focus is narrow: enterprise-oriented B2B companies with clear ICP, strong retention potential, and efficient go-to-market signals. Its sector specialization and hands-on diligence, including customer validation through its CXO network, raise the bar meaningfully.
