How It's Built

Full-stack voice SaaS on Next.js App Router. Vapi handles the phone layer with custom assistant configs per practice. Supabase stores leads, practices, calls, TOS acceptances, and the Minions job queue. Stripe Connect in LIVE mode handles checkout and per-practice billing. Resend sends transactional + drip email. Public marketing surfaces (pricing, FAQ, legal), partner landing pages at /for/[slug], and authenticated client dashboards at /client/[slug]/dashboard coexist in one Next.js app behind a middleware that gates admin + client routes.
