Status
Live as a product — public signup open
ShiftBook is L7's only productized SaaS — multi-host booking with payments built in, designed as a Calendly replacement and shipped as a public sign-up product. It doubles as proof-of-build for the methodology: the same Next.js + Supabase + Stripe stack as Scat Pack, repurposed as a SaaS others can use.
What L7 built
01Multi-host booking surface (one workspace, individual branded host pages)
02Stripe Connect integration for charging time, deposits, or full session fees at booking
03Calendar integrations: Google Calendar + iCal, with conflict detection
04Magic-link signin (no passwords) and host onboarding wizard
05Brand customization per host (colors, logo, copy)
06Self-serve signup flow at shiftbook.l7shift.com level routing
Outcomes
✓L7's internal Calendly subscription cancelled day one
✓Built and shipped end-to-end in days, not the months a traditional SaaS rollout assumes
✓Public signup live as a real product — not a demo, not a mockup
✓Documented build log published as the "Killed Calendly" insights article

How L7 ships at this pace
Every engagement runs through Kenneth Leftwich (Founder & Principal — ex-Gartner Fortune 50 partner, $106M optimized at Lowe's), AI-accelerated execution via L7's internal agents, and an operator-stays partnership. The SymbAIotic Shift™ is how the work ships in days, not quarters.
