Fifteenth raises $8.25 million in seed funding to revolutionize tax preparation for tech professionals

SAN FRANCISCO: Fifteenth, a tax solution designed to meet the unique needs of founders, investors, executives, and tech professionals with complex financial situations, announced Tuesday it has raised $8.25 million in seed funding. The funding round was led by A and General Catalyst, with participation from SV Angel and several prominent angel investors, including Swapnil Jain, CEO of Observe.AI; Ryan Eisenman, CEO of Arch; and Akash Garg, advisor at Electric Capital.

The company, which aims to simplify tax preparation for individuals navigating complex financial landscapes such as equity compensation, liquidity events, and partnership income, has already helped employees from tech giants like Nvidia, Rippling, and Figma save an average of $10,000 to $20,000 annually through tailored tax strategies. Some clients have saved as much as $100,000 using Fifteenth’s custom scenario modeling for strategic stock option sales.

Fifteenth leverages cutting-edge AI technology, customized scenario modeling, and seamless integrations with enterprise platforms like Workday and Rippling, as well as fintech platforms such as Robinhood, Wealthfront, and Carta. The company offers unlimited, year-round tax advice and proactive quarterly planning starting at $1,000 per year, ensuring clients are covered every step of the way.

“With Fifteenth, April 15th is just another day – no stress, no chaos,” said Ankur Dahiya, CEO of Fifteenth. “Gone are the days of scrambling to find, enter, re-enter, and distribute piles of financial documents. We created Fifteenth to combine top-tier tax support with AI-driven solutions for tech professionals, and this seed funding is a key step in scaling the future of tax preparation.”

Dahiya, a second-time founder with a background in executive roles at Rippling, Flexport, X, and Meta, co-founded Fifteenth with Laura Moreno, the company’s chief tax officer. Moreno brings extensive experience in handling complex tax scenarios for high-net-worth individuals and tech professionals, having previously led teams at PwC, a billion-dollar family office, and Carta, where she built and managed the tax advisory team.

Fifteenth’s services include unlimited access to CPAs with experience at top-tier firms like Andersen and Apercen, tailored tax strategies for equity and liquidity optimization, and an AI-powered document vault to organize critical financial information. The platform also integrates with a wide range of financial tools, including Workday, Rippling, Robinhood, Wealthfront, Carta, Charles Schwab, AngelList, and Coinbase.

“Fifteenth is redefining the tax preparation landscape by combining cutting-edge AI technology with a deep understanding of complex financial needs,” said Gautam Gupta, co-founder and general partner of A*, who is also a Fifteenth customer. “The process of working with a CPA has remained largely unchanged for decades—dominated by email, manual data entry, and a lack of modern technology. Fifteenth’s unique blend of tax expertise and technical innovation addresses this long-overdue pain point, and we’re thrilled to partner as they redefine the tax experience for the modern professional.”

With its latest funding, Fifteenth plans to expand its services and continue transforming the tax preparation experience for tech professionals and others with intricate financial portfolios.
