Astor, an SEC-registered investment advisory platform powered by artificial intelligence, has successfully secured $5 million in seed funding to create greater access to personalized financial advice for average American investors.
The funding round was spearheaded by Monashees, with additional contributions from Y Combinator, Goodwater Capital, Gilgamesh Ventures, 468 Capital, Valutia, Sunshine Lake, along with individual investors from Stripe and OpenAI.
Since its launch, Astor has attracted thousands of users, linking over $200 million in brokerage accounts to its platform. The new capital will be utilized to enhance Astor’s product development, engineering capabilities, and growth initiatives, while also expanding its service offerings.
The company was co-founded by Bruno Koba and Daniel Tulha, who were raised in Brazil, where it is customary to be matched with a financial adviser when opening a brokerage account, regardless of wealth. Upon moving to the United States, they were surprised to find that most Americans manage their investments without professional assistance.
The duo participated in Y Combinator’s Summer 2025 program to develop their solution. Koba previously worked as a FinTech investor at Monashees and as a data scientist at Nubank, where he focused on utilizing machine learning to enhance credit access. Tulha has a background in engineering from his tenure at Stripe and Robinhood, where he contributed to financial infrastructure projects.
Astor aims to address a significant gap in the market. Traditional financial advisers often require clients to possess a minimum of $500,000 in assets, leaving many Americans without access to tailored professional advice.
The platform directly connects to users’ existing brokerage accounts, assessing their portfolios based on performance, risk, and diversification. It then provides personalized recommendations while adhering to a fiduciary duty that mandates it to act in the best interests of its clients.
Bruno Koba, co-founder and CEO of Astor, remarked, “We observed that many people around us were investing independently, with numerous individuals treating their brokerage accounts like a casino. In our home country, even the most basic advisor offers the reassurance that someone is overseeing your finances. In the U.S., without wealth, this support is largely absent.”
Fabiola Quinzaños, a partner at Monashees, stated, “Most individuals do not require more investment products; they need effective guidance. Astor empowers people with the knowledge they need to take control of their financial future.”
She further noted, “Bruno offers the perspective of an investor from his time at Monashees while also personally understanding this issue, and Daniel provides the technical expertise from developing financial products at Stripe. It’s a full-circle story that we are pleased to support.”
