The verdict
Increase appears in 5 AI-ranked categories — best position #2 for banking-as-a-service apis for embedded finance startups.
Clean, exceptionally well-documented API over direct bank rails with a reputation for correctness and uptime; exposes primitives (ACH, wires, real-time payments, checks, cards) without hiding them, idempotency and reconciliation done right. Best fit for a startup that treats banking infrastructure as a serious engineering dependency.
Where Increase falls short, per the models
- Claude Premium, opinionated, and not the cheapest or fastest-to-first-launch; minimal hand-holding and no rich pre-built UI, so under-resourced teams needing a fast MVP will struggle.
Top alternatives per the models: Column · Unit · Stripe Treasury · Treasury Prime
Best US-first banking infrastructure for teams needing precise control: unified accounts, ACH, wires, RTP, FedNow, checks, and Visa issuing, with unusually granular network data and strong reconciliation primitives; ranked assuming a technically capable team building embedded business accounts at scale
Gemini Exceptional developer-first APIs and virtual ledger primitives mapping directly to banking rails with complete operational transparency, high performance, and multi-bank redundancy.
Claude Developer-grade API with unusual depth on the actual payment rails (ACH, RTP, wires, checks, lockbox) and direct Fed-adjacent infrastructure rather than reselling a processor; near-tie with Column for engineering quality — ranked below because its bank footing is less self-contained and its product surface for full business-banking programs (cards, lending) is narrower.
Where Increase falls short, per the models
- GPT Its low-abstraction design shifts more compliance, operations, and product assembly onto the customer
- Claude Rails-first and minimalist — you're assembling a banking product from primitives with little program-management or compliance scaffolding; wrong choice if you need a packaged BaaS program.
- Gemini Lacks a turnkey compliance program, shifting the integration and regulatory burden entirely onto the client.
Top alternatives per the models: Column · Unit · Stripe Treasury · Treasury Prime
API-first, direct-to-bank integration with famously precise, well-documented primitives (ACH, wire, RTP, real-time card, check) and event-driven design; issues business accounts with less abstraction leakage than middleware. Trusted by serious fintechs for correctness and reliability.
Gemini Delivers exceptional developer experience with precise, low-level programmatic primitives for ACH, FedWire, RTP, and business checking accounts alongside realistic sandbox testing. Flagged near-tie with Column on developer ergonomics, but ranked second because it relies on partner bank charters rather than owning a national bank license.
Where Increase falls short, per the models
- Claude Selective and premium — courts established programs over pre-revenue startups, offers less of a full self-serve compliance/onboarding layer, so scrappy early-stage teams may not get in or served well.
- Gemini Lacks pre-built white-label UI components and fully managed compliance programs, so it is not for non-fintech SaaS platforms needing plug-and-play regulatory coverage.

Bank-grade ledger exposed through a clean, well-documented API with direct rail access (ACH, wires, RTP, cards), giving real balances backed by an actual bank so internal wallet entries reconcile against real money movement.
Where Increase falls short, per the models
- Claude US-only and effectively a BaaS/bank whose ledger is oriented around funds on its own rails, not an arbitrary general ledger — poor fit for global marketplaces or purely internal multi-currency wallet accounting.

Top alternatives per the models: Formance · TigerBeetle · Modern Treasury · Fragment
Best when the ledger and the money are the same system — a direct bank-connected API where ledger primitives (accounts, entries, holds) are backed by real settlement, giving unusually tight consistency between recorded and actual balances for US-based programs.
Where Increase falls short, per the models
- Claude It's a banking/BaaS platform first, US-centric, and you effectively adopt its rails — not a standalone, provider-agnostic ledger you can put over arbitrary payment sources.
