Question 1

What is Column?

Accepted Answer

Column is a nationally chartered bank built specifically as developer infrastructure for the modern fintech ecosystem. Unlike traditional banks, Column combines a federal banking charter with a completely custom-built technology stack designed from the ground up to serve fintech companies and developers.

The bank positions itself as a "platform bank" that provides API-driven banking infrastructure, enabling technology companies to build financial products without navigating legacy banking systems or multiple middleware providers. Column offers FDIC-insured deposit accounts, payment processing, card programs, and lending facilities through developer-friendly APIs.

Question 2

When was Column founded?

Accepted Answer

Column was founded in 2019 by William Hockey and Annie Hockey, who serve as co-CEOs. William Hockey previously co-founded Plaid, the pioneering financial data connectivity company, where he witnessed firsthand the challenges fintech companies faced working with traditional banking infrastructure.

The Hockeys acquired Northern California National Bank in 2021 for approximately $50 million and spent three years building proprietary technology to replace the bank's legacy systems. Column publicly launched in April 2022 as the first nationally chartered bank purpose-built for developers. The bank charter itself dates to March 28, 2006, when the original bank was established, but Column's modern incarnation began with the 2021 acquisition.

Question 3

Where is Column headquartered?

Accepted Answer

Column is headquartered in Chico, California, located in Butte County. The bank maintains its main office at 1717 Mangrove Avenue in Chico, operating from what has been described as a "very adorable strip mall." While the headquarters remains in Chico, Column's technology-driven operations serve clients nationwide.

Question 4

Where does Column operate?

Accepted Answer

Column operates nationally across all 50 states as a federally chartered bank under the supervision of the Office of the Comptroller of the Currency (OCC). The bank maintains one physical branch location in Chico, California, but its primary operations are digital and API-based.

Column's client base is concentrated in major technology hubs, particularly serving fintech companies headquartered in San Francisco, New York, and other major metropolitan areas. The bank's infrastructure supports financial services delivery anywhere in the United States through its platform partners.

Question 5

What services does Column offer?

Accepted Answer

Column provides comprehensive banking-as-a-service infrastructure through developer-friendly APIs, including:

Payment Services: Direct connections to the Federal Reserve, The Clearing House, SWIFT, and card networks enable ACH transfers (utilizing all five settlement windows), domestic and international wire transfers, real-time payments, book transfers, and check processing with remote deposit capture.

Deposit Products: Programmable FDIC-insured bank accounts including checking, savings, trust, subledger, clearing, and sweep accounts. Developers can instantly create flexible account structures, from single accounts to millions of virtual account numbers.

Card Programs: End-to-end card issuance and management for debit, credit, prepaid, secured, and charge cards. Customers can launch card programs with dedicated BINs and choice of issuing processors while optimizing interchange revenue.

Lending Services: Credit origination, warehouse facilities, forward flow arrangements, and debt financing. Column provides capital to help partners scale lending programs faster with loan origination, purchase, and financing capabilities.

Digital Banking Platform: RESTful APIs with comprehensive documentation allow developers to integrate banking functionality directly into applications. The platform includes compliance tools, real-time transaction monitoring, and full ledger visibility.

Question 6

What makes Column unique?

Accepted Answer

Column's distinctiveness lies in its vertical integration model—it is simultaneously a nationally chartered bank and a modern technology company, eliminating traditional middleware layers.

Built-from-Scratch Technology: Unlike traditional banks, Column constructed its entire technology stack in-house, including its own core banking system, ledger, and data models. This provides unmatched speed, flexibility, and direct Federal Reserve connectivity without legacy system constraints.

Developer-First Approach: Column designed every aspect of its platform specifically for developers and builders, offering "financial services as code" with comprehensive API documentation and developer support.

Ownership Structure: Column is 100% founder and employee-owned, remaining profitable without venture capital funding. This structure allows long-term focus on infrastructure quality rather than short-term investor returns.

Blue-Chip Fintech Partnerships: Column powers major fintech platforms including Mercury (which processed over $156 billion in transactions in 2024), Brex, Ramp, Built Technologies, and Wise. These partnerships demonstrate Column's ability to handle enterprise-scale operations.

Regulatory Excellence: As a nationally chartered bank supervised by the OCC, Column maintains robust compliance infrastructure while moving quickly to help partners launch products. This regulatory positioning helps partners avoid the compliance pitfalls that have affected other banking-as-a-service providers.

Question 7

What type of financial institution is Column?

Accepted Answer

Column is a National Bank chartered under federal law and supervised by the Office of the Comptroller of the Currency (OCC). As a nationally chartered commercial bank, it holds Federal Reserve membership and provides full-spectrum banking services.

However, Column represents a unique hybrid category: it functions as a Banking-as-a-Service (BaaS) Infrastructure Bank specifically designed to power other financial technology companies. Unlike traditional commercial banks that serve retail or business customers directly, Column primarily serves fintech companies, developers, and enterprises building financial products.

This positions Column as both a regulated banking institution and a technology infrastructure provider—effectively serving as the "AWS of banking" for the fintech ecosystem.

Question 8

Who are Column's founders?

Accepted Answer

Column was founded by husband-and-wife team William Hockey and Annie Hockey, who serve as co-CEOs with clearly delineated responsibilities.

William Hockey co-founded Plaid in 2012 with Zach Perret, building it into a $13.4 billion company that became the backbone of fintech data connectivity. In 2020, Visa agreed to acquire Plaid for $5.3 billion before the deal was blocked by the Department of Justice. William stepped down from day-to-day operations at Plaid in 2019 but remains on its board. His experience building Plaid revealed the immense challenges fintechs face working with legacy banking infrastructure, directly inspiring Column's creation.

Annie Hockey leads regulatory, legal, accounting, and human resources functions at Column. She previously worked at Bain & Company and Goldman Sachs, and was an early employee at various Silicon Valley startups. Annie graduated with honors from Stanford University and Stanford's Graduate School of Business, where she was an Arjay Miller Scholar.

The couple's complementary skill sets—William's technical and product expertise combined with Annie's regulatory and operational acumen—enable Column's unique position bridging banking regulation and modern technology.

Question 9

What is Column's revenue model?

Accepted Answer

Column generates revenue through two primary streams that have demonstrated strong growth:

Interest Income: Column earns interest on customer deposits and loans, benefiting as fintech partners scale their customer bases. This provides stable, recurring revenue tied to deposit growth.

Non-Interest Income: Transaction-based fees including interchange revenue from card programs, API usage charges, payment processing fees, and lending facilitation fees. This revenue stream grew significantly as partners like Mercury and Brex increased transaction volumes.

In 2024, Column's revenue reached approximately $55.1 million, representing 126% year-over-year growth. The revenue mix is balanced between interest income ($28 million) and non-interest fees ($27 million), providing diversification and demonstrating the platform's value beyond traditional banking margins.

Question 10

How does Column differ from traditional Banking-as-a-Service providers?

Accepted Answer

Traditional BaaS providers like Unit, Synctera, or Galileo act as middleware, sitting between fintech companies and sponsor banks. This creates a three-layer structure: fintech → middleware → sponsor bank, with each layer adding cost, complexity, and potential points of failure.

Column eliminates the middleware layer entirely by being both the bank and the technology provider. Fintech partners integrate once with Column's APIs and gain direct access to a nationally chartered bank's capabilities—FDIC insurance, Federal Reserve connectivity, and regulatory compliance—without navigating multiple vendors or legacy core banking systems.

This vertical integration reduces costs, accelerates product launches from months to days, minimizes regulatory risk, and gives partners complete control over their customer experience. Column's model represents the evolution from "banking-as-a-service" to "banking-as-software," where the bank itself is the technology platform.
