In 2025, fintech startups have experienced a remarkable resurgence after a couple of slow years. According to recent data from CB Insights, fintech companies globally raised $10.3 billion in the first quarter of 2025, marking the highest level of funding since the first quarter of 2023. The average deal size, reaching $17.7 million, was the highest since 2021, signaling a strong investor interest in the sector. This resurgence is particularly noteworthy as many fintech companies are now receiving substantial funding after a period of cautious investments due to market instability.
While crypto-related fintech startups are seeing larger rounds of funding, there’s also significant interest in other types of fintech companies, such as those focusing on payments, banking, fraud prevention, and wealth management. Here’s a detailed breakdown of some of the most notable U.S.-based fintech startups that have raised over $50 million in funding in 2025, according to PitchBook data:
April Highlights:
- Plaid:
Plaid, the fintech giant known for connecting bank accounts to financial applications, raised an impressive $575 million in funding. The round was led by Franklin Templeton, with additional participation from new investors such as Fidelity Management and Research, BlackRock, and other notable investors. Despite initial confusion, Plaid clarified that this was not a Series E round, but rather a sale of common stock. This distinction is important because, in this type of financing, the company issues new shares directly to raise capital, as opposed to a secondary sale, where existing shareholders sell their shares to other investors. With this funding, Plaid continues to solidify its position as a leader in the financial technology space.
