History

  • Co-CEO & CTO@TROOP (formerly TroopTravel)2017–2025Cited source

Notable work

  • TROOP (TroopTravel) — meetings & group travel logistics platformCited source

    Raised $19M+ including Madrona Ventures; scaled across South Africa and internationally; sold/exited 2025.

  • Stratafy methodology — strategy as codeSelf-attested

    Effect Schema implementation of typed strategic entities, four execution layers, homeostatic loop, validators, anti-pattern detectors.

  • Professional rally co-driverSelf-attested

    Competes in Dakar Rally and major South African cross-country events with Century Racing Team.

What I'm good at

  • Turning complex human processes (strategy, compliance, identity) into executable, auditable code via typed DSLs and validator systems.
  • Building opinionated, deeply consistent multi-repo TypeScript stacks with zero tolerance for architectural drift across 6+ projects.

How I think

  • Schema before story — settle the data model before the marketing copy.
  • Receipts on the table — every load-bearing claim ships with the evidence and the verifier.
  • Identity belongs to the person, not the issuer.
  • Ship before the meeting — group discussion without an artefact is the most expensive form of thinking in a startup.

Active projects

  • AetherID — build-and-test window, decision point 3 July 2026
  • Stratafy — pre-PMF, pushing toward first revenue (30-day horizon)
