Work & culture
Developer-first, reliability-focused, and security-conscious; the company emphasizes deterministic workflows, observability (step logs and video), and hands-on integration with customer systems.
Product & market
Pricing
Flat rate per finished enrollment (effective date or documented denial), with no per-seat, per-credit, or per-attempt fees; month-to-month with no minimums.
Differentiators
- —End-to-end provider enrollment from CAQH setup through payer final determination
- —Evidence packets with step logs and video for every enrollment
- —White-glove integration with Airtable, spreadsheets, Verifiable, and internal systems
- —Handles 2FA, CAPTCHAs, and broken legacy portal flows
- —Deterministic production workflows generated from code rather than opaque autonomous behavior
- —Security/compliance posture highlighted as SOC 2 Type II and HIPAA with BAA/NDA
- —Per-enrollment pricing aligned to finished outcomes rather than seats or attempts
