Astor
AI Investment Advisor for Retail Investors
Last verified August 18, 2026 · Updated daily
What Astor is building
Astor is an AI investment advisor that gives retail investors the same kind of real-time market tracking, deep research, and personalized alerts that institutional investors rely on. Their AI agents uncover opportunities, decode emerging trends, and deliver tailored analysis, basically a personal Goldman Sachs research desk for everyday investors. The product (available at joinastor.com) lets you call or chat with your AI advisor anytime, 24/7. It's a voice + chat interface, not just another stock screener or charting tool. Note: Astor was previously called "Gaus" (joingaus.com still redirects to the product), they recently rebranded, which is itself a signal of market positioning refinement and upcoming growth push.
Why this matters
Retail investors now account for 25% of all U.S. trading volume, nearly double from 2012. But 56% still don't feel confident in their investment decisions. There are 160M+ stock-owning Americans, and the tools they use (brokerages, news sites, Reddit) haven't fundamentally changed in 15 years. The AI advisor category is heating up, but Astor has an unusual founder combination: one founder was a data scientist at Nubank (building ML models for millions of users) and a fintech VC at monashees (Brazil's top VC, $2B+ AUM), while the other was an engineer at Stripe, Robinhood, and Amazon building production AI systems. They've seen the institutional edge from the inside and the retail struggle from the user side.

With only <50 employees, Astor doesn't have dedicated recruiters. Founders review applications between running the company. The challenge isn't competition — it's visibility. Direct outreach wins.
Who to contact at Astor
Founding team
Stanford GSB MBA (Class of 2025) and Botha-Chan Fellow - a program sponsored by Sequoia's Roelof Botha that selects only 30 students. Before Stanford, he was a data scientist at Nubank from 2018 to 2020, building ML models that impacted millions of users. He then joined monashees, Brazil's leading VC ($2B+ AUM), as a Senior Associate where he led deal teams for 8 seed/Series A investments, including two companies now valued over $1B (Merama and Clara), and deployed $180M+ across 15+ follow-on rounds. Deeply connected to the LatAm fintech ecosystem - Nubank's CEO David Vélez is also Stanford GSB, and Bruno interviewed Vélez at Stanford. His communication style is very active on LinkedIn: substantive posts about VC, fintech, and entrepreneurship. He engages thoughtfully with comments, is approachable, but expects substance. He values people who have conviction about a market.
Ex-Stripe, Robinhood, and Amazon software engineer who's been building production-ready AI agents and scaling systems for years. At Robinhood, he scaled systems during the meme stock booms and volatile markets, exactly the kind of high-throughput, high-stakes engineering that Astor needs. At Stripe, he worked on core infrastructure. When YC S25 accepted them, he posted on LinkedIn: "After helping Robinhood scale during some of the wildest markets in history, we're building the AI advisor that every retail investor deserves." His communication style is more technically oriented than Bruno's, and he's likely the person evaluating engineering candidates.
What to show them
Build a mini AI investment chat interface. Use the OpenAI or Anthropic API paired with a financial data source (Alpha Vantage, Polygon.io, or Yahoo Finance API) to create a conversational AI that can answer portfolio-related questions. Bonus points if you add voice input/output to match Astor's actual product. Skills that matter: React Native or Flutter for mobile, Next.js for web, API integrations with financial data providers, WebSocket for real-time data, and experience building consumer-facing products at scale. Reach Daniel directly on LinkedIn.
A cold email that works at Astor
What Astor screens for
Astor AI (YC S25), a lean 5-person fintech squad fresh off Demo Day in late 2025, is screaming "hiring spree ahead" via the classic post-YC playbook: snag a $3-6M seed round fast (often from networks like Sequoia's) and explode headcount to 15-20 within 6 months to capitalise on momentum. Plus, their accelerating product traction (e.g., early beta user growth or API integrations hinted in YC updates) is likely fueling burn-rate needs for engineering). CEO Bruno Koba supercharges this - Stanford Botha-Chan Fellow (Roelof Botha's direct Sequoia scout pipeline), ex-Monashees deal lead behind $1B+ exits - while his recent LinkedIn fires up Brex/Nubank scaling tales and VC/founder chats, pure pre-raise signaling for Q1 2026's aggressive growth phase before that seed PR hits (think Monashees or Sequoia announcements greenlighting AI-fintech hires).
Don't send a generic CV to Astor. Mirror the job posting's language to get past automated screening.
Don't make these mistakes
Don't send generic AI enthusiasm. Lead with specific proof of work - a demo, a growth plan, or sample research briefs. Reference the rebrand from Gaus to Astor, the Robinhood scaling experience, or the monashees portfolio work. Show you understand the retail investor pain point.
Mistakes that kill Astor applications
At <50 people, a copy-paste CV is immediately obvious. It's an instant no.
Lead with their problem, not your ambition. Astor is focused on Retail investors now account for 25% of all U — show you understand that.
Don't apply and wait. The median Fintech, Consumer Finance application gets no response ever. One follow-up at day five roughly doubles reply rates.
