Buildbridge
A two-sided home-services marketplace with Stripe milestone escrow, atomic role-based user provisioning, multi-county permit-portal integrations, a regionally-defensible Storm Mode feature, and native iOS and Android wrappers. Built as the Platform tier exemplar for B2B2C marketplaces in coastal markets.

Marketplace mechanics
- Atomic role-based user provisioning (bb_provision_user_atomic): single-transaction User + UserRole + role-profile creation
- Stripe milestone escrow — funds held, released per phase signoff
- Bid request → contractor matching → quote → award flow
- License + insurance verification gate on contractor onboarding
- Multi-step project state machine (request → bid → award → milestones → close)
- Dispute escalation flow with operator-facing resolution panel
Regional moat — Storm Mode
- NOAA storm RSS + active-storm RPC feeds
- Pre-approved Storm Mode contractor panel with on-call opt-in
- One-tap mobilization — operator triggers the response panel

A real marketplace, with real defenses.
Buildbridge proves Day14 can ship the most operationally complex tier — two-sided marketplaces with escrow, native mobile, and region-specific integrations that lock out generic out-of-state competitors. The Storm Mode and multi-county permit pieces are non-trivial to reproduce and locally defensible for years.
