AI (Artificial Intelligence) Startups funded by Y Combinator (YC) in New York 2026

WithAI helps institutional investors research stocks and track their portfolio using AI. Today's agents are powerful but insufficient. The training data quality and customization schlep prevent them from being seriously useful for investors. But WithAI has found the right form factor, context management, and consultative sale to help independent asset managers hold their own against the huge platforms' in-house projects. Our first client is "tremendously accelerated" (their words) when months ago they were "existentially threatened." Ben and Ian became fast friends at Princeton co-founding a technology investment firm. Ben became the founding researcher at unicorn Sentient Labs, where he built LLM coordination and security tech. Ian became an investor at Bridgewater Associates, where he spearheaded "how will AI affect the economy?" and "how can we use LLMs to invest?" His contrarian conclusion: the future of work isn't just "managing agents." That form factor works for coding, but non-verifiable work is structurally different. You check whether code is good by running it. But do you check whether a stock is good by shorting it? Fundamental equity hedge funds are elite, time-constrained, un-automatable knowledge workers in dire need of AI augmentation, so they make an ideal customer. But the combination of customization lock-in and huge ACV is not the real prize. If human knowledge work survives this decade, it will be AI-augmented. We're building that augmentation.

Foresight builds AI-powered simulations of human behavior to help companies predict how people will think, react, and choose before making real-world decisions.

Autonomous is a superintelligent financial advisor at 0% advisory fees. Today, managing your money means one of two bad options: DIY your money: You end up with accounts everywhere (401k, IRAs, brokerage, crypto, savings, equity, secondaries). Your spreadsheet is always wrong. You make expensive mistakes because this isn't your full-time job. Hire a financial advisor: They'll manage your money and charge 1-2% of assets annually. Run that math over multiple decades and you're handing over half your net worth to fees. Neither path can economically deliver the sophisticated, personalized strategies the ultra-wealthy use to compound wealth: strategic tax-loss harvesting across individual securities, systematic risk management, portfolio-backed borrowing to defer capital gains, access to alternatives, etc. These aren't secret – they're just economically impossible to deliver at scale through traditional human advisors. Robos were supposed to fix this, but they were designed in a pre-AI world. In practice they just manage cookie-cutter portfolios. They don’t coordinate across your 401(k), taxable accounts, mortgage, equity, and cash flow, they don’t help with real decisions like job offers, windfalls, or concentrated stock, and they don’t deliver institutional strategies. That’s why, even after a decade plus, the biggest robos are still <$100B AUM while old-school advisors like Raymond James / Edward Jones sit on trillions. We’re doing for financial advising what Robinhood did for brokerages. Think of it as a full-stack, AI-native wealth strategist that brings billionaire-style playbooks to ordinary investors. Autonomous is built around a frontier-scale reasoning engine—an AI that perceives global events as they unfold, understanding their deeper implications for markets and and most importantly, how these events will impact your investments.

DiligenceSquared delivers AI-powered market due diligence for investment decisions - like the $500k McKinsey reports, but automated, auditable, and at a fraction of the cost. When Private Equity funds evaluate deals, they pay firms like McKinsey, BCG, and Bain $500K-$1M for market due diligence. The process takes weeks, and the output is a static PowerPoint that's impossible to audit. A single large-cap PE fund can spend >$30M annually on this and the total market is $10B per year. Our AI agents conduct expert interviews and synthesize insights with every claim linked to source transcripts. No black box, no "trust me" slides, and no 10x mark-up for human labor. Frederik bought these reports as a Principal at Blackstone. Soren sold them as a Principal at BCG. Harshil is a repeat founder and former Software Engineer at Google. We've seen both sides and know what matters in due diligence - and now we automate it. Our clients already include 8 leading private equity funds with over $2.4 trillion in combined AUM.

Feedback becomes immediate, instruction adapts weekly, and learning iterates (measure, adjust, improve) so every student progresses faster with less teacher burnout. Frizzle was named an official White House AI Education Partner alongside OpenAI and Meta: https://www.whitehouse.gov/edai/. Frizzle was co-founded by Abhay Gupta and Shyam Sai, who met in high school over 10 years ago.

Fleetline is building the first complete-context algorithmic load planner for mid to large-sized trucking fleets. Today’s dispatchers face an overwhelming task: balancing regulations, customer demands, live fleet data, and individual driver needs, all while coordinating across siloed tools and teams. Mistakes run rampant, and each mistake is thousands of dollars. Even the select fleets using algorithms that have fleet-wide context struggle: the outputs are rigid, hard to interpret, and are blind to real-world nuances like driver preferences and schedule exceptions. Fleetline solves this by combining advanced optimization with LLMs that can easily adapt algorithms to each fleet’s needs and capture driver-specific information. The result is smarter planning truly optimized for every fleet and its drivers.

Channel3 is building a database of every product on the internet. Google and OpenAI maintain vast product graphs, but keep that valuable data to themselves. Channel3 gives every developer access, opening a world of possibility for new shopping experiences across any vertical. For instance, developers could build AI fashion stylists or give their agents shopping capabilities. We don’t just collect product data; we actually understand it. With the latest image classification and reasoning models, we can match products across merchants—even when listings and images differ—recognize variants, and surface the perfect matches for every search. As we grow, we’ll capture unique insights into what users want, click, and buy. As AI models get smarter and cheaper, our flywheel accelerates: our catalog will improve, and it will be even easier for developers and vibe-coders to build on our infrastructure. To further incentivize building on Channel3, we provide built-in monetization; developers earn commissions on sales they drive. Alex discovered this need while building an AI tutor that could recommend products and earn affiliate revenue. When no solution existed, he persuaded his smartest friend from Duke and former co-founder George to leave Palantir and build Channel3 together.
