Company Overview
About Teller
Teller is a US-focused banking API that gives developers direct, real-time access to bank account data and payment initiation without relying on screen scraping or batch-updated aggregation services. Unlike legacy financial data aggregators that use credential-based scraping and update account data nightly, Teller establishes direct connections to major US financial institutions and retrieves live transaction and balance data. This approach results in higher data quality, faster refresh rates, and more reliable connections that do not break when banks update their web interfaces.
Business Model & Competitive Advantage
The platform covers accounts at major US banks including Bank of America, Chase, Wells Fargo, Citi, and hundreds of regional institutions. Teller exposes a clean REST API for retrieving account balances, transaction histories, and identity information, and supports payment initiation through ACH and real-time payment rails. Its developer experience is deliberately simple — authentication, account linking, and data retrieval are designed to require minimal code, with comprehensive documentation and a sandbox environment for testing.
Competitive Landscape 2025–2026
Teller competes with Plaid and MX in the US open banking infrastructure space, differentiating through its direct bank connections and emphasis on data freshness. The platform is well-suited for personal finance apps, cash flow lending products, payroll verification tools, and any application where stale or inaccurate bank data creates user trust issues. Teller has attracted developer-centric fintech teams that have experienced reliability problems with incumbent aggregators and prefer a technically transparent alternative with straightforward, usage-based pricing.
