Bio
Co-founder and longtime CEO of HubSpot, now an in-house CEO coach at Sequoia Capital. Public reference voice for the LOCK+S CEO evaluation rubric, the spiky-vs-un-weakness hiring frame, and peer-room learning models for executives.
Operating themes
- LOCK + S rubric. Lovable, Obsessed, Chip-on-shoulder, Knowledge, Student.
- Hire spiky. Real strengths and real weaknesses beat well-rounded averages.
- Hire slow, fire fast. Most teams do the opposite.
- Peer rooms learn faster than coaches. Misery loves company; same-stage CEOs teach each other best.
- Distribution is the new moat. Starting has never been easier; scaling has never been harder.
Cards
- Evaluate CEOs and senior operators on Lovable, Obsessed, Chip-on-shoulder, Knowledge, Student — Five-letter rubric weighting Student as the under-rated dimension [Tier B]
- Hire spiky candidates with real strengths and real weaknesses, not the un-weakness average — Hire 4s and 2s, not 3s across the board [Tier B]
