# Evaluate CEOs and senior operators on Lovable, Obsessed, Chip-on-shoulder, Knowledge, Student

## Claim
Use a five-letter rubric for evaluating CEOs and senior operators: Lovable (would a 28-year-old version of you crawl across glass to follow them?), Obsessed (deep founder-market fit, evidence of going down rabbit holes), Chip on the shoulder, Knowledge of the domain, Student (learn-it-all, not just know-it-all). The Student dimension is the under-rated differentiator.

## Mechanism
Conventional CEO rubrics weight pedigree, charisma, and visible domain knowledge, all of which are pattern-matchable and easily faked. The LOCK+S rubric forces an operator to demonstrate the harder-to-fake dimensions: would the best people you have ever known follow them? Have they actually obsessed over their problem or are they performing? Are they still curious, or have they stopped learning? The Student check filters for operators who will adapt to the next era; the Knowledge check filters for operators who can lead today.

## Conditions
Holds when:
- The role is leadership or senior IC where adaptation matters as much as current execution.
- The hiring team has access to genuine references (people the candidate actually led).
- The team is willing to weight peaks (high L, O, S) over averages (no major weakness).

Fails when:
- The role is narrow, technical, and stable; raw current capability dominates.
- The references are sanitised and you cannot pressure-test L or O.
- The hiring team substitutes pedigree for the rubric and uses the letters as decoration.

## Evidence
> The rubric: L (Lovable) — would a 28-year-old you crawl across glass to follow them? O (Obsessed) — evidence of going deep. C (Chip on shoulder). K (Knowledge of domain). S (Student) — learn-it-all, not know-it-all.

Brian Halligan ran HubSpot for ~20 years and now coaches Sequoia portfolio CEOs. The rubric is what he uses across that cohort.

## Signals
- Reference checks return concrete stories on each letter rather than generic praise.
- Hires made with this rubric outperform pedigree-led hires over an 18-month window.
- Boards using the rubric kill candidates earlier when L or S are missing, regardless of K.

## Counter-evidence
The rubric encodes Halligan's preferences for founder-style leadership and may filter out steady operators who run mature companies well. Operators who succeed in turnarounds, regulated industries, or pure execution roles may not fit cleanly into LOCK+S.
