BoxGroup Founder David Tisch: Financial AI Company Rogo's Series A Round Faced Collective Rejection
David Tisch, founder of early-stage investment firm BoxGroup, publicly stated that the Series A funding for financial AI company Rogo was "one of the most unexpected outcomes" of his career. He mentioned that almost all investors rejected Rogo at the time, and it was only Keith Rabois who stepped up to lead the investment after others had given up, "seeing the magic in it."
Tisch's post was prompted by Rogo co-founder and CEO Gabe Stengel publicly recounting this funding experience. Tisch noted that Stengel had "long moved past that moment" and believed that it was his persistence that found an investor willing to step in when others had given up. BoxGroup was an early investor in Rogo, participating from the seed round and later in the Series A and D rounds.
Rogo's Series A round raised $18.5 million, led by Khosla Ventures with Keith Rabois as the lead partner. Co-investors included Jack Altman's AltCapital, Original Capital, and Mantis VC, founded by The Chainsmokers, while existing investors AlleyCorp, BoxGroup, and ScOp Venture Capital also increased their stakes. At that time, Rogo's product was an AI tool that automatically drafted memos, built financial models, and created presentations for investment banking personnel, handling tens of thousands of queries daily. Within five months of its establishment, it achieved a seven-figure annual recurring revenue (ARR) with just one salesperson.
After the Series A, Rogo's funding pace accelerated significantly. In April 2025, Thrive Capital led a $50 million Series B round, post-money valuation reaching $350 million. In January 2026, Sequoia led a $75 million Series C round, post-money valuation reaching $750 million, while the company also entered the European market. In April 2026, Kleiner Perkins led a $160 million Series D round, with a valuation reaching $2 billion, and institutions like J.P. Morgan Growth Equity Partners participated, bringing total funding to over $300 million.
On the business front, Rogo has served over 35,000 professionals across more than 250 financial institutions, including clients like Rothschild & Co, Jefferies, Lazard, Moelis, Nomura, and GTCR. Industry estimates show its ARR grew from about $15 million at the end of 2025 to about $53 million by August 2026, with an annual fee of about $3,300 per seat, plus separate charges for professional data access. It launched the AI platform Felix, covering processes such as deal screening, CIM (Confidential Information Memorandum) generation, buyer outreach, data room due diligence, and research automation, and also acquired UK financial market tracking company Plux AI and AI agent company Offset.
Founded in January 2022, Rogo's three co-founders, Gabe Stengel, John Willett, and Tumas Rackaitis, are all Princeton University alumni. Stengel worked as an investment banking analyst at Lazard from 2020 to 2022, and the inspiration for the startup came from the release of GPT-3 and his undergraduate thesis on an econometric chatbot.
In terms of market mechanisms, this is a typical valuation path of "early rejection followed by late funding influx." At the Series A stage, mainstream institutions were generally skeptical about "vertical AI for investment banking," fearing that large banks would build their own tools, and data giants like Bloomberg and FactSet would also enter the fray. A few contrarian investors like Khosla secured low-priced stakes. As revenue validation occurred, large funds like Thrive, Sequoia, and Kleiner Perkins entered at higher valuations, resulting in significant paper gains for early investors. The parties under pressure are traditional financial data and terminal providers like Bloomberg, FactSet, and S&P Capital IQ, as well as outsourced research service providers, along with the hiring scale of junior analyst positions in investment banks.

Keith Rabois is a member of the "PayPal Mafia" and has held executive positions at PayPal, LinkedIn, and Square. He left Square in 2013 due to a workplace lawsuit controversy and joined Khosla Ventures the same year. He co-founded the real estate transaction platform Opendoor, moved to Founders Fund in 2019, and returned to Khosla in early 2024. During his time at Founders Fund, he invested in corporate spend management company Ramp, which grew into a fintech company valued at over $10 billion. His investment style has always been to "bet on a single strong founder rather than consensus sectors." David Tisch comes from the Tisch family of Loews Corporation and previously led Techstars New York. His firm, BoxGroup, primarily focuses on seed rounds and has early investments in Plaid and Airtable, excelling at small-scale investments before consensus forms.
From a capital path perspective, Rogo's funding trajectory exemplifies the relay of capital in vertical AI: the seed and Series A rounds were risked by early-stage firms like BoxGroup, AlleyCorp, and Khosla, while from the Series B onward, large funds like Thrive, Sequoia, and Kleiner Perkins took over, with the Series D round bringing in J.P. Morgan's growth fund, effectively turning clients into shareholders. The underlying strategy is clear. Investment banking clients are willing to pay for saving junior analysts' labor hours, and once Rogo integrates into their trading data, CRM, and data rooms, the switching costs will rise rapidly. Its acquisition of Plux AI enhances market data capabilities, and the acquisition of Offset strengthens execution capabilities, aiming to upgrade from a "research assistant" to an AI operating system for investment banks.
The closest historical analogy is the Bloomberg Terminal. In 1981, Michael Bloomberg founded his company after leaving Salomon Brothers, with Merrill Lynch as his first major client. Merrill Lynch invested about $30 million for a 30% stake in Bloomberg in 1985, becoming a shareholder while also a client, and the terminal quickly became a standard on Wall Street. Similar vertical AI cases include Harvey in the legal field, which was also initially questioned with the concern that "law firms would build their own tools," but later saw its valuation rise to billions. On the other hand, large banks are pursuing in-house development: JPMorgan launched its internal tool LLM Suite to about 200,000 employees in 2024, and Goldman Sachs also launched its own AI assistant. AlphaSense acquired Tegus for about $930 million in 2024, indicating that data and research platforms are consolidating through mergers and acquisitions. Currently, financial vertical AI is in a stage of "independent platform expansion, with giants pursuing in-house development and acquisitions in parallel."
Essentially, this is a technological substitution. The traditional organizational structure of investment banks is a pyramid: a large number of junior analysts handle modeling, presentation preparation, and due diligence work, trading low wages and long hours for promotion opportunities, allowing banks to dilute delivery costs. A first-year investment banking analyst in the U.S. has a base salary of around $110,000, while Rogo's annual fee per seat is about $3,300, a price difference of over 30 times. As long as AI can complete some of the standardized work, banks have a strong incentive to shrink the base of the pyramid. Investors generally rejected Rogo at the Series A stage because they valued it based on the market size of "tool software"; the later influx of funds was due to the market re-pricing based on "substituting junior labor costs." The valuation logic shifted from selling software to replacing labor, which is why Rogo's valuation jumped to $2 billion within two years.
