Sethi is no criminal, though, and the house is not just his home. It is also the prime outpost for Kraken, the longtime cryptocurrency exchange where Sethi, who draws few lines between his personal and professional life, is co-CEO. The gray-flecked 42-year-old, who favors plain t-shirts, may not be concerned what his neighbors think of him. But he does have to care about the opinions of another group: Kraken’s investors, who are expecting big things in the near future.

Founded in 2011, Kraken has long flown under the radar compared to its bigger competitor Coinbase, but has always commanded the respect of traders and crypto veterans. In the past year, the company has reached for a bigger share of the spotlight with high-profile acquisitions and product launches ahead on an IPO planned for next year. All of this will test whether Kraken can meet the lofty $15 billion valuation that came with a new funding round it closed this month.

Meeting that challenge will fall to Sethi who, despite an official title of co-CEO, is very much calling the shots at Kraken. An executive whose experience lies primarily in venture capital, he is an unusual choice to lead a company on the cusp of going public, but one very much in keeping with Kraken’s history as an unconventional company.

Building the future of trading

Sitting at a large desk plunked in the center of his sparse living room one August afternoon, Sethi patiently replies to my questions as random figures pop in and out of the garage. He has a wide range of intellectual interests—he dabbled in journalism in college and has read extensively on major religions—but for Sethi nearly everything comes down to data.

After founding a pair of startups and working as a senior product manager at Yahoo, Sethi co-founded the venture capital firm Tribe Capital. Even more than its peer VC firms, Tribe has a reputation for data-based decision making, which led to bets on Kraken, as well as on Carta, which makes cap-management software, and the cloud computing firm Docker, among others.

If the unsentimental Sethi has a passion, it is the idea of using blockchain technology to fix obstacles in the financial system that prevent people from tapping into collateral they own. He cites, for instance, the common conundrum faced by employees who leave a startup and must exercise their stock options and pay related tax within 90 days—resulting in many of them simply walking away from their equity. The solution, Sethi says, is tapping into the modular stack of services offered by decentralized finance (DeFi), which promises to give consumers an unprecedented degree of control over their assets, and let them lend or securitize them like never before.

“My hope with crypto is to distribute those benefits more evenly. We’re not all the way there, but the first steps are happening—stablecoins, then tokenized assets, and now tokenized equities,” said Sethi.

His vision is for Kraken to be a hub for all of these things, bringing the best elements of crypto and the traditional financial stack under one umbrella. To this end, the company spent $1.5 billion this spring to buy NinjaTrader, a platform for professional asset traders, in a move that boosted Kraken’s customer base by 2 million and represented, in Sethi’s words, the “largest-ever deal combining TradFi and crypto.”

Coinbase is the dominant player in retail crypto, but Kraken’s bread-and-butter has always been professional and institutional customers. Lately, though, Kraken has been pushing to expand its presence in retail, including with the launch of xStocks, which are shares of popular companies like Apple and Tesla, wrapped in crypto and tradable on blockchains.

The concept of blockchain-based stocks may seem exotic or downright unnecessary, but look closer and the early response to xStocks appears to validate Sethi’s views on where finance is going. He notes that xStocks, which will be available in the U.S. next year, are taking off in markets like South Africa where the fees to purchase traditional stocks from brokerages can still be over 10%. By offering shares on a decentralized blockchain platform—xStocks can even be traded outside of Kraken’s exchange—there is less opportunity for middlemen like brokerages to exact high fees.

Kraken is one of a handful of trading firms, including Robinhood, that are offering tokenized assets, and some big Wall Street names like BlackRock are doing the same. If this is indeed where the world is heading, it will be the latest instance of Kraken being ahead of the curve; previous examples include the exchange being one of the first to list Ethereum and to offer crypto derivatives.

Unlike most startups, Kraken made it this far with very little in venture capital funding, raising only $27 million from its founding until this year. That recently changed, however, as the company decided to raise a $500 million round as part of its final gear-up for an IPO. The Information reported in July that the company was seeking to raise that amount; this week Fortune learned, from a person who was not authorized to discuss the matter publicly, that it successfully closed the round this month. The round featured no primary investor with Kraken itself setting the terms, including the $15 billion valuation, said the person. Contributors included investment managers and venture capitalists, as well as Sethi’s Tribe Capital and Sethi in a personal capacity.

The investors are pouring money into a thriving business that pulled in nearly $80 million in post-EBITDA earnings, and over $411 million in revenue in the second quarter, according to figures published by Kraken. Those numbers, along with the firm’s longevity and strong reputation in the industry, put it in position to be one of the strongest of the crypto firms entering or on the cusp of entering public markets. If there is a wildcard, though, it may be the firm’s senior leadership.

Executive turnover at Kraken

Following our sit-down interview, Sethi and I take a turn around his Menlo Park neighborhood, and return to his house for dinner with a member of his team and a cousin who has turned up. The meal is delicious but unusual.

The cousin has arrived with coolers full of stone crabs, which he and Sethi scatter on plates of ice around the kitchen. There is a shortage of crab utensils but, since this is Silicon Valley, Sethi punches an order into an app and more appear at the door in a matter of minutes—a trick he performs several times over the course of my visit.

The main course comes in the form of thin, marinated filets of something (Sethi won’t say what) that have arrived in a same-day delivery from Wyoming. Sethi artfully grills the stack of filets in his backyard, serving them with a nice California red and that’s all.

The dinner was par for the course for how Kraken operates more broadly.

For its first decade, Kraken was defined by its co-founder, Jesse Powell. A soft-spoken philosophy major and self-described introvert, Powell steered the company through various crises that buffeted the crypto industry. At some point along the way, he took on a more abrasive persona on X, posting comments on topics like gender and pronouns that made him a villain among certain mainstream media outlets. A working-class kid from Sacramento, Powell has also been game to spar with San Francisco liberals, including by suing a co-op he says denied his bid to buy a unit on grounds of his politics. (The case is ongoing).

In 2022, Powell stepped down as CEO amid a federal investigation into his role at a Sacramento arts non-profit he had founded. The probe created a multi-year legal ordeal for Powell, including an FBI raid of his house that was leaked to the New York Times.

The Justice Department this summer acknowledged Powell had done nothing wrong, but the three-year legal cloud resulted in tumult at the top of Kraken. On stepping down, Powell named longtime lieutenant Dave Ripley as CEO, but last year the company announced Sethi had taken on the role of co-CEO.

A co-CEO arrangement is unusual at the best of times and, according to multiple people with ties to the company, it is basically a fiction in the case of Kraken. One former executive, who asked not to be named in order to speak candidly, said that on a Zoom call shortly after the co-CEO announcement, an employee asked Powell who would be making decisions; the founder stated definitely that Arjun would decide everything—even as Ripley, the now co-CEO, sat nearby.

That same person praised Sethi’s command of product, but also complained that the new leader appeared indifferent to staff morale, and has run Kraken more like a venture capital firm than a company, relying on outside associates more than longtime staff. The person added that Sethi’s ongoing ties to Tribe Capital, where he is Chairman, pose a conflict of interest.

“Arjun is Chairman of Tribe Capital, but doesn’t run [Tribe’s] business day to day. This arrangement was approved by both the Kraken and his LPAC [Limited Partner Advisory Committee] at Tribe,” said a Kraken spokesperson.

Sethi’s arrival also roughly coincided with the departure of a number of senior executives, including Kraken’s CTO, its COO, senior sales staff and its longtime lawyer. While executive turnover occurs at every organization, the scope of change at Kraken has likely contributed to the company’s IPO bid getting pushed to 2026 even as a spate of other crypto firms have gone public this year.

The Kraken spokesperson addressed the turnover by pointing to an October blog post by Sethi and Ripley titled A New Day, saying “we made a number of changes to the organization to eliminate layers and make the organization leaner and faster.” She acknowledged the shakeup had affected morale, but added that employees are not “energized and excited” as Kraken’s pace of shipping products picks up.

Another former executive contacted by Fortune, who asked not to be identified due to legal constraints, also made the case that Sethi’s disruptive management style was necessary to prepare the company for its IPO push. The person added that Kraken’s many years in business had resulted in more pre-IPO regulatory and operational issues than other firms, and added that the co-CEO role has served the company well, with Ripley excelling at internal operational issues and Sethi handling sales and public-facing roles.

For his part, Sethi described his co-CEO as a “multiplier of the strategy because Kraken has so many products” and said he is seeking to build a management structure similar to what Mark Zuckerberg has done at Meta, where dedicated teams serve each of the company’s discrete brands.

IPO clock is ticking

Following a period of investor exuberance that peaked in 2021, the window for new companies to go public all but closed as investors came to see startups valuations as overly inflated. That finally changed this year and, for crypto companies, a new appetite for public companies combined with regulatory tailwinds has led to an IPO bonanza.

In the last few months, stablecoin issuer Circle enjoyed one of the biggest same-day IPO pops in corporate history, while lesser lights of the crypto scene like Gemini and Bullish also made successful public debuts. For Kraken’s investors, the company’s decision to wait until 2026 to list publicly is likely a source of frustration and anxiety. Will the market still be eager for another crypto IPO?

There is cause for concern on this front. There are a growing number of indicators that current stock prices are overvalued and, in the case of the newly listed crypto firms, their business prospects appear tenuous. In Circle’s case, declining interest rates are a direct drag on the firm’s stablecoin revenue, while both Bullish and Gemini have far fewer customers than the likes of Kraken and Coinbase. If the current crypto bull run is followed by a crash, as has happened in numerous previous cycles, these firms’ share prices risk being clobbered.

All of this increases the pressure on Kraken to hasten its IPO. But if the bottom falls out of the market before it has time to list, Kraken investors can take comfort that—far more than most other crypto firms—it has a sound business model and multiple revenue streams. The company is also seeing growth in numerous key markets outside of its longtime strongholds of Europe and the U.K.

This means Kraken, regardless of how its IPO plans shake out, is built to play the long game.

“Our model’s built around pro traders and institutions,” says Sethi. “Features like Kraken Pro, our robust API, and advanced interfaces make us a destination for funds and high-volume clients—they use our exchange not because it’s flashy, but because it works and the liquidity is deep.”

In the future, Kraken will be in an even better position if Sethi’s vision of a total convergence of traditional finance and crypto comes to pass. If it does, the company’s investors and executives—especially Sethi—stand to make a tidy bundle. So much so that Sethi will have the resources to easily fund a charm offensive to win over his suspicious neighbors—provided, of course, that he cares about such things.
