Pick Relay if…
The Profit-First-aligned multi-checking neobank — 20 real checking accounts (not virtual envelopes) and 50 debit cards under one login, with granular multi-user roles. Where Mercury / Bluevine / Novo all give you one operating account plus virtual sub-pockets, Relay gives you 20 separately-FDIC-mapped checking accounts that auto-transfer between each other on percentage- or amount-based rules. That is the structural fit for Mike Michalowicz's Profit First method (Income / Profit / Owner's Pay / Tax / OpEx envelopes), and Relay has been the official Profit First banking platform since 2023. Sponsor bank is Thread Bank (TN-chartered) with a $3M sweep — Thread's May 2024 FDIC consent order was terminated December 2025 with no customer-funds incident at Relay.
