Industry Overview & Funding Trends

The fintech industry experienced a volatile period between 2021 and 2025, moving from a period of “easy money” to a “harsh funding winter” before stabilizing in the last year. While venture capital investment in private fintech companies increased by 35% to $53 billion in 2025 – the first gain in four years – it remains significantly below the $152 billion raised in 2021. A major factor influencing this shift is the dominance of Artificial Intelligence (AI) companies in attracting venture capital. In 2025, AI companies secured $226 billion in funding, representing nearly $1 of every $2 invested in venture capital overall. This has led to a “dispersion in valuations” within the fintech sector. Publicly traded fintech companies like Block, PayPal, and Coinbase experienced stock declines exceeding 10% in 2025, while Robinhood saw a surge of nearly 200%. Five companies from the 2025 Fintech 50 list went public, but four are currently trading below their Initial Public Offering (IPO) prices.

The 2026 Fintech 50: Focus on B2B & Enterprise Solutions

The 2026 Forbes Fintech 50 list reflects a shift towards companies serving other businesses. Specifically, Business-to-Business (B2B) banking, Wall Street, and enterprise-focused fintechs comprise 20 of the 50 spots – a significant portion of the list. B2B banking startups hold the largest representation with 11 companies, many of which are repeat appearances from previous years.

• Column: An FDIC-insured bank co-founded by Plaid co-founder William Hockey, doubled its revenue to over $200 million in 2025 and made the list for the third time.
• Mercury: Offering a range of services from business checking to working capital loans, Mercury achieved its third consecutive year of profitability and appeared on the Fintech 50 for the fourth time, with revenue reaching $650 million.
• RAMP: A corporate credit card startup, experienced a valuation increase from $22.5 billion in July 2025 to $32 billion in November 2025, marking its sixth year on the Forbes Fintech 50.

Wall Street & Enterprise Software

Startups providing software solutions for Wall Street firms also performed well.

• Antithesis: Utilizing AI, this Virginia-based company stress tests software for bugs, assisting trading firms in avoiding potentially costly errors. Quant powerhouse Jane Street became a customer in January 2025 and subsequently led Antithesis’s $15 million Series A funding round in December.
• Mayburn: Based in New York, Mayburn automates accounting processes for private market funds. It serves over 20 customers, including real estate and private equity funds managing a collective $80 billion.

Personal Finance & Consumer-Facing Fintech

Eight companies focused on personal finance made the list.

• Monarch: A budgeting app that gained popularity after Intuit shut down Mint in 2024. Monarch offers features like goal setting, category budgeting, and an AI assistant, serving over 500 paying subscribers and raising funding at an $850 million valuation.
• Possible Finance: Provides small-dollar loans ($50-$500) to low-income consumers in 33 states, offering a flexible alternative to payday loans with installment payment options and rescheduling capabilities. Since its founding in 2017, Possible Finance has loaned over $1.75 billion to 1.5 million people.

Payments Landscape

The payments sector experienced a mixed year. While some established players like PayPal saw stock declines, certain private startups showed resilience. The number of payments companies on the Fintech 50 list decreased from 11 to 7.

• Rain: A newcomer to the list, Rain facilitates the movement, storage, and utilization of cryptocurrency-based stablecoins, experiencing a tripling of its valuation to $1.95 billion between 2025 and January 2026.
• Stripe: The payments giant achieved its highest valuation ever at $17 billion in 2025 and made the list for its 11th year.
