Top Fintech Companies in the US
The fintech sector has gone through a wild ride over the past few years. After the hype and record funding rounds of 2021, the industry hit a major correction. Valuations dropped, venture capitalists got cautious, and several high-profile companies either imploded or scrambled to cut costs.
By 2026, the dust has settled quite a bit. The companies that survived are leaner, more profitable, and in some cases have gone public. Others that once made headlines are now cautionary tales. Here’s a look at ten fintech companies that have shaped the US market and where they stand now.
Top 10 Fintech Companies
1 – Stripe
Stripe was founded in 2011 and helps businesses of all sizes process online payments, manage business loans, and handle sales tax automatically. It remains the most valuable private fintech company in the US, though its valuation has fluctuated from a peak of $95 billion in 2021 to around $65-70 billion based on more recent secondary market activity.
Despite the valuation adjustment, Stripe’s actual business has grown significantly. The company processed well over $1 trillion in payments annually and continues to add new products for businesses. Stripe has repeatedly pushed back IPO timelines, but investors and analysts still expect it to go public eventually.
2 – Klarna
Klarna pioneered the buy-now-pay-later (BNPL) model and helped push consumers away from traditional credit card payments. The company lets shoppers purchase items and split payments into interest-free installments.
Klarna’s path has been a rollercoaster. After peaking at a $46 billion valuation in 2021, the company raised a down round at roughly $6.7 billion in 2022. Since then, Klarna has focused aggressively on profitability, cut staff, and leaned into AI-powered customer service. By 2024, the company filed for an IPO in the US. It’s one of the biggest BNPL players globally and continues to add retail partners.
3 – FTX (Collapsed)
FTX was once considered one of the largest crypto exchanges in the world, valued at $32 billion in early 2022. That all came crashing down in November 2022, when the company filed for bankruptcy after it was revealed that customer funds had been misused.

Founder Sam Bankman-Fried was convicted of fraud and sentenced to 25 years in prison in 2024. FTX’s collapse sent shockwaves through the entire crypto industry and led to tighter regulations. The company’s bankruptcy proceedings have distributed some funds back to creditors, but FTX remains one of the biggest financial frauds in recent history. It’s included here as a reminder that valuation alone doesn’t equal a solid business.
4 – Chime
Chime is the largest digital-only bank in the US. It grew popular by offering free checking accounts with no overdraft fees and early access to direct deposits.
The company was valued at $25 billion in 2021 and was expected to go public in 2022. Market conditions pushed the IPO back repeatedly. Chime has continued to grow its user base through word of mouth and low fees. For millions of Americans who don’t want to deal with traditional banking fees, Chime is their primary financial account.
5 – Ripple
Ripple focuses on international payments and remittances through blockchain technology and its associated cryptocurrency, XRP. The company has over 300 institutional clients, including MoneyGram, Santander, and Standard Chartered.
Ripple spent years in a legal battle with the SEC over whether XRP is a security. The case produced mixed results, with some rulings favoring Ripple on certain aspects. Regardless of the legal drama, Ripple continues to handle a significant volume of cross-border transactions, especially to Mexico and Southeast Asia.
6 – Blockchain.com
Blockchain.com is a British-founded crypto platform that’s also one of the most popular cryptocurrency wallets in the world. It lets users manage private keys for Bitcoin, Ethereum, and other major currencies.
Founded in 2011, the company claims to have handled well over 100 million crypto wallets and more than $1 trillion in transactions since launch. After expanding to the US, Blockchain.com now serves customers in dozens of states. Like most crypto companies, it has seen revenue tied closely to market cycles, with slower periods during crypto downturns and surges during bull runs.
7 – Plaid
Plaid was founded in 2012 and acts as the connector between fintech apps (like Coinbase and Venmo) and customers’ bank accounts. If you’ve ever linked your bank to an app, there’s a good chance Plaid handled the connection behind the scenes.

The company was valued at $13.4 billion in 2021 after a planned $5.3 billion acquisition by Visa fell through due to antitrust concerns. Plaid has continued to expand its services, adding identity verification and fraud detection after acquiring Cognito. It’s become a piece of infrastructure that a large portion of the fintech ecosystem depends on.
8 – OpenSea
OpenSea rode the NFT wave of 2021-2022 to massive heights. At its peak, the platform processed about $3 billion worth of NFT transactions per month. Its valuation hit $13.3 billion.
The NFT market has cooled down significantly since then. Monthly transaction volumes on OpenSea dropped by over 90% from their peak. The company has had to cut staff and restructure. While OpenSea still operates and remains one of the better-known NFT marketplaces, the broader market for digital collectibles hasn’t returned to 2021 levels. Whether NFTs make a meaningful comeback remains an open question.
9 – Brex
Brex offers corporate banking products aimed at startups and tech companies. Their lineup includes FDIC-insured corporate cash management accounts, corporate credit cards with no personal guarantees, and integrated expense tracking features.
The company has shifted its focus over time. In 2022, Brex stopped serving small businesses to concentrate on larger startups and enterprises. They’ve introduced lending services for venture-backed companies and acquired budgeting software to strengthen their product suite. Brex counts companies like Airbnb and DoorDash among its customers.
10 – GoodLeap
GoodLeap is a California-based fintech that finances green home upgrades. The company partners with banks like Goldman Sachs to originate loans, then securitizes the debt to sell to investors.
Contractors and vendors use GoodLeap’s point-of-sale app to get homeowners approved instantly for projects like solar panel installations. The company offers financing across more than 20 categories, including energy-efficient windows, battery storage, and water-saving turf. With growing interest in residential clean energy and home electrification, GoodLeap has positioned itself well in the green finance space.
What This List Shows
These ten companies represent different sides of fintech, from payments and banking to crypto and green energy lending. Some have thrived, some have struggled, and one collapsed entirely. The fintech sector in 2026 looks very different from the boom years of 2021, but the companies that adapted, cut costs, and focused on real revenue are still here and still growing.
