Astor Secures $5 Million Seed Round to Scale AI-Driven Investment Advisory Platform

New updates have been reported about Astor.

Astor, an SEC-registered, AI-native investment advisory platform, has raised a $5 million seed round led by Monashees with participation from Y Combinator, Goodwater Capital, Gilgamesh Ventures, 468 Capital, Valutia, Sunshine Lake, and executives from Stripe and OpenAI. The capital will fund expansion of Astor’s product, engineering, and growth teams as the company broadens its service lines to address a large segment of U.S. investors currently underserved by traditional advisors.

Since launch, Astor has attracted thousands of users and more than $200 million in connected brokerage accounts, signaling early traction for its model of delivering personalized guidance at scale via AI. Co-founders Bruno Koba and Daniel Tulha, who previously held roles at Monashees, Nubank, Stripe, and Robinhood, designed Astor to fill the advisory gap for investors who lack access to human advisors, a market where typical minimums often start at $500,000 in assets.

Astor’s platform links directly to users’ existing brokerage accounts, evaluates portfolios across performance, risk, and diversification, and then issues tailored recommendations aligned with a fiduciary duty to act in clients’ best interests. This approach positions the company as a regulated alternative to social media-driven investing and generic chatbots, a critical distinction as a growing share of younger investors rely on online content for financial decisions.

The company is targeting a structural shift in U.S. retail investing, where participation has increased but behavior often resembles speculative trading in meme stocks, crypto, and prediction markets. By combining conversational AI with direct portfolio analysis rather than pushing new products, Astor aims to become a scalable, low-friction advisory layer on top of existing brokerage infrastructure.

Koba and Tulha’s experience building data-driven financial systems at scale underpins Astor’s technology and its ability to systematize advice that has historically been delivered through high-touch, high-cost human advisors. For investors and partners, the seed round underscores confidence that tech-enabled fiduciary advice can reach a broader base of households, with Astor positioned to capture demand as regulatory scrutiny of unregulated advice and speculative behavior continues to rise.

Looking ahead, Astor plans to deepen its AI capabilities, expand the range of portfolio insights and recommendations it provides, and grow distribution to reach millions of U.S. households currently managing investments alone. If execution matches investor expectations, the company could emerge as a key intermediary between mass-market investors and the broader capital markets, potentially pressuring traditional wealth management models that rely on high asset thresholds and manual service.
