Astor Raises $5M for AI Advisor to Tackle US Investment Advice Gap

SAN FRANCISCO, CA – April 23, 2026 – Astor, an AI-native investment advisory platform, today announced it has secured a $5 million seed round to democratize access to financial guidance for millions of Americans. The round was led by Latin American venture capital firm Monashees, with significant participation from Y Combinator, Goodwater Capital, and prominent executives from Stripe and OpenAI.

Registered with the Securities and Exchange Commission (SEC), Astor operates as a fiduciary, a legal standard that obligates it to act in its clients' best interests. The company’s platform connects directly to users' existing brokerage accounts to analyze their portfolios and provide personalized, data-driven recommendations. This new capital injection will fuel the expansion of Astor’s product, engineering, and growth teams as it aims to scale its services. Since its launch, the platform has already gained considerable traction, attracting thousands of users and connecting to over $200 million in assets.

The Rise of the Casino Market

The funding arrives at a critical juncture for the American retail investor. While more people are participating in the market than ever before, the landscape has become increasingly speculative. The rise of meme stocks, volatile cryptocurrencies, and social media-fueled trading has transformed investing from a long-term wealth-building strategy into a form of high-stakes entertainment for many.

According to a recent study by the Financial Industry Regulatory Authority (FINRA), a staggering 61% of investors under the age of 35 now rely on social media for investment decisions. This trend creates a fertile ground for misinformation and herd-like behavior, often leading to poor financial outcomes. Meanwhile, the traditional source of sound advice—human financial advisors—remains largely inaccessible. Most wealth management firms enforce high asset minimums, frequently requiring clients to have $500,000 or more to invest. Consequently, only about 35% of Americans work with a financial advisor, a figure that plummets to below 5% for adults under 30, leaving a vast advice gap for the majority of the population.

An AI Fiduciary to Bridge the Gap

Astor aims to fill this void by leveraging artificial intelligence to deliver institutional-grade guidance at scale. Unlike generic AI chatbots or the unvetted advice circulating on social media, Astor is an SEC-registered investment adviser. This registration is not merely a formality; it legally binds the platform to a fiduciary duty, ensuring its recommendations are tailored to the user's specific financial situation and long-term goals, free from conflicts of interest.

The platform works by securely linking to a user's existing brokerage accounts, such as those with Fidelity, Schwab, or Robinhood. Its AI then performs a comprehensive analysis of the user’s holdings, evaluating them on key metrics like performance, risk exposure, and diversification. Using a conversational AI interface, Astor delivers its findings and tailored recommendations, helping users understand the strengths and weaknesses of their current strategy and suggesting concrete steps for improvement. This approach empowers users to make more informed decisions with the assets they already own, rather than pushing them into new, proprietary products.

A Founder's Journey and a Full-Circle Story

The inspiration for Astor stemmed from the personal experiences of its co-founders, Bruno Koba and Daniel Tulha. Having grown up in Brazil, they were accustomed to a financial system where it is standard practice for investors to be paired with a financial advisor upon opening a brokerage account, regardless of their net worth. Upon moving to the United States, they were struck by the stark contrast.

"We looked around and everyone we knew was investing on their own, with many treating their brokerage accounts like a casino," said Bruno Koba, co-founder and CEO of Astor. "Back home, even the most basic advisor gives you the sense that someone is paying attention to your money. Here, unless you're wealthy, nobody is."

This observation spurred the pair to join Y Combinator's Summer 2025 batch and build a solution. Their backgrounds provided the perfect blend of expertise. Koba previously served as a fintech investor at Monashees—the firm now leading Astor's seed round—and as a data scientist at Nubank, where he developed machine learning models for credit scaling. Tulha brings deep engineering experience from his time building financial infrastructure at both Stripe and Robinhood.

Fabiola Quinzaños, a Partner at Monashees, highlighted this unique synergy. "Most people don't need more investment products, they need someone in their corner. Astor gives people the knowledge and guidance to actually take control of their financial future," she stated. "Bruno brings the investor perspective from his years at Monashees and the personal conviction of having lived this problem, while Daniel brings technical depth from building financial products at Stripe, and Bruno going from Monashees investor to Monashees-backed founder is the kind of full-circle story we love to be part of."

With its new funding and a clear mission, Astor is poised to challenge the status quo, offering a powerful tool for the millions of investors navigating an increasingly complex market on their own.
