Today, Chime’s annualized revenue is running at a $600 million rate, according to a person familiar with the private company’s numbers. At its eye-popping new valuation of $14.5 billion announced along with a $485 million fundraise in mid-September, venture capitalists are valuing the company at 24 times its revenue. Some investors are asking if Chime should get such a lofty value when Green Dot, a publicly traded fintech that offers checking accounts and prepaid debit cards for low-income customers, trades at two times revenue. “We really look more like a payments-processing business,” answers Britt. That’s because virtually all of Chime’s revenue comes from interchange—the fees merchants pay when Chime’s users swipe their debit cards. The company doesn’t make money on interest through its new secured credit card (that’s a starter card where the holder puts up money to cover his or her credit limit), although Britt says he doesn’t rule out lending in the future.

Now Britt himself has sailed into the “three-comma club.” Forbes estimates his Chime stake is at least 10%, meaning his holdings are worth $1.3 billion-plus (Forbes applies a 10% discount to all private company holdings). And he’s planning an IPO. “Over the next 12 months, we have a number of initiatives to get done to make us even more IPO-ready,” he says.

Then there’s the Robinhood phenomenon. The boredom of being stuck at home, wild stock market swings and government stimulus checks have turned some Millennials and Generation-Zers into day traders and options players. Robinhood’s most recent fundraising round in September gave it an $11.7 billion valuation and its cofounders a paper net worth of $1 billion each. But considering Morgan Stanley’s $13 billion February acquisition of E-Trade and Schwab’s earlier purchase of TD Ameritrade for $26 billion, some think Robinhood could garner a $20 billion valuation if it went public or were acquired.

If there’s one fintech segment that has been an unalloyed pandemic winner, it’s the business Afterpay is in: online point-of-sale installment financing. It’s benefiting from both consumers’ shift to online buying and their reluctance, in these uncertain economic times, to take on new credit card debt.

While Afterpay’s Nick Molnar and Anthony Eisen hit billionaire status in July, their competitors aren’t far behind. Take Klarna, which was founded in Stockholm in 2005 and entered the U.S. market in 2016. Two of the three founders, Sebastian Siemiatkowski and Niklas Adalberth, met while flipping patties at a Burger King in Sweden. They pioneered the buy-now, pay-later model in fintech, calling it “try before you buy” and letting people own products for 30 days before making their first payment. (That’s a lot more attractive than old-fashioned layaway, the store system once popular for Christmas gifts and large appliance purchases, in which buyers had to make all their installment payments before getting an item.)

Klarna charges retailers 3% to 4% of each transaction—slightly lower than the 4% to 5% Afterpay charges—to offer its service. One key difference that separates the two companies: Klarna is becoming a full-fledged financial services business. It became a licensed bank in Sweden in 2017 and offers longer-term financing of up to 24 months, with interest charged, for high-ticket items like laptops sold through a small number of retailers. Siemiatkowski has already turned Klarna into a digital bank in Europe with a debit card for spending on everyday purchases. He’ll likely do the same in the U.S. soon.

The pandemic has catapulted Klarna’s business onto a steep trajectory. By the end of 2020’s first half, its U.S. customer base hit 9 million, up 550% from the same period the year before. Globally, 55,000 consumers are downloading the Klarna app every day, more than two times last year’s pace. Klarna is now available in 19 countries, has 90 million users and expects to bring in more than $1 billion in revenue this year. When it raised a new round of funding last week, its valuation nearly doubled from a year ago, hitting $10.7 billion.

Cofounder Victor Jacobsson has a 10% stake, while Siemiatkowski’s has 8% in the still-private company. (Niklas Adalberth retains just 0.4% after selling some shares to fund his philanthropic organization and investing in startups. Neither he nor Jacobsson are still involved in Klarna.)

Not surprisingly, as the installment purchasing fintechs gain more customers and attention, they’re also facing additional scrutiny from regulators. In March, Afterpay agreed to fork over $1 million, including $905,000 in consumer refunds, after California’s Department of Business Oversight (DBO) concluded the late fees Afterpay charges meant it was running an unlicensed lending business. “Afterpay rejects the view that the Company operated illegally,” the Australian company said in a statement. “While Afterpay does not believe such an arrangement required a licence from the DBO, Afterpay has agreed to conduct its operations under the DBO licence as a part of this settlement.” A spokesperson adds that Afterpay “has been applying for, and has been granted licenses [in other states] where needed.” In 2017, Klarna was fined $15,000 in New Hampshire for operating without a lending license. Today Klarna has such licenses in every U.S. state.

Another fintech winner in the installment-payment business is Silicon Valley-based Affirm, the creation of serial entrepreneur Max Levchin, a founder of PayPal, which itself jumped into the installment business just last month. Between November 2019 and July 2020, Affirm nearly doubled its U.S. users to 5.6 million. It raised $500 million last week at a valuation of more than $5 billion, up from $2.9 billion last year. While Levchin’s exact stake is undisclosed, it’s likely worth hundreds of millions.

Affirm has also enjoyed a special Covid kicker from pricey home fitness gear. Since 2015, it has powered financing for Peloton, whose sales have surged as affluent young consumers, missing the motivation of group exercise classes, have flocked to buy the $2,000-plus stationary bikes with their streaming workout classes. Affirm also now finances purchases of Mirror, the hot $1,495 in-home fitness coaching device acquired by Lululemon this summer.

Of course, the fintech companies’ current lofty valuations depend on consumer spending staying strong and consumers retaining some of the online shopping habits they’ve developed over the past six months. With a preelection agreement between Congress and the White House on a new stimulus package looking unlikely and the future course of Covid-19 unknown, there are no guarantees. But for now, these fintechs are riding high.
