# Use peer mentorship instead of HR overhead to scale supply quality

## Claim
For marketplace supply scaling, paid peer mentorship beats centralized onboarding. Lyft paid top drivers $35 per mentor session to onboard new drivers, share routes, tips, contact info. Community advocacy outperforms marketing copy. The pattern was ~10x more efficient than Uber's office-based DMV-style approach.

## Mechanism
Centralized onboarding (offices, training videos, support agents) scales linearly with cost. Peer mentorship scales with supply itself, every new top performer becomes a potential mentor. The mentor's tacit knowledge transfers in a single session in ways no curriculum captures. Quality stays high because mentors stake their reputation in the community. Cost stays low because per-session pay beats fixed staff overhead.

## Conditions
Holds when:
- The supply side has natural community signals (forums, top performers, peer recognition).
- Top performers will accept mentor pay as worthwhile relative to their core earnings.

Fails when:
- The supply side has no community structure. Peers don't know each other; no mentors exist.
- The mentorship turns into informal labor exploitation, mentors feel underpaid and disengage.

## Evidence
> "Lyft paid top drivers $35/mentor session. Mentors shared routes, tips, contact info. Community advocacy beats marketing copy. 10x efficiency vs. Uber's office-based onboarding."

## Signals
- New supply onboarding cost per active provider falls relative to traditional approaches.
- Activation rate of mentor-onboarded supply is higher than self-serve onboarded.
- Mentors report it as a revenue line, not a chore.

## Counter-evidence
The pattern requires a critical mass of top performers who care about the community. Early-stage marketplaces don't have that yet, they need centralized onboarding until peer mentorship is feasible. The transition point is non-obvious and easy to miss.
