Investments Startups funded by Y Combinator (YC) 2026

Oasive helps bond investors decide what to buy and sell, and why. It unifies research, screening, analysis, valuation, and reporting in one platform, automating work that today takes teams of analysts. Live today across MBS and macro research, with municipal bonds, rates, ABS, and corporates next.

In investment management, every decision gets graded. The market prints the answer on a date known in advance, and nobody gets to argue with it. Kimpton is financial AI that answers to reality. Kimpton OS is the AI-native operating system for investment teams: it does the research and hands PMs structured trades. EarningsBench is a public benchmark where models forecast quarterly earnings before companies report and the reported numbers do the scoring. Koliseum is the set of point-in-time financial environments we build from that work, for labs to train and evaluate models on. The whole industry is fighting underperformance. Active managers trail their benchmarks, and capital keeps bleeding into passive. AI was supposed to fix that, but it hasn't. Funds either stitch together a dozen point tools or babysit general agents all day, and neither gets them to the trade. Kimpton OS goes straight to it. It ingests a fund's mandate, strategy, and positions, connects to the institutional data the fund already runs on, and returns a structured trade proposal built for that fund. It's built to disagree, because consensus is poison for investment decisions. Instead of telling a PM what they want to hear, it surfaces the breaches and risks they'd otherwise miss. That same work is how we grade AI. Static benchmarks leak into training data. Simulations reward what their authors imagined. A forecast sealed before the outcome exists and scored when the company reports can't be rehearsed or backdated. We started in markets because they're the one place reality answers on schedule. We're two ex-Goldman engineers and an ex-SpaceX engineer. We left to start our own quantitative systematic hedge fund, raised $10M from a family office at 21 and 22, and scaled it to $35M over four years. We learned to trust live results over historical fit. We built Kimpton inside that fund, then productized the stack. We're live with our first institutional client, a $3.3B manager. Our first market is fundamental equity funds from $1B to $10B, and the labs that need to know whether their models can do this work.

Zarna is private equity's first AI associate class. Built for BD teams at middle-market firms, our agents manage your CRM, source new opportunities, and prep you for every meeting. Runs natively in Outlook and Teams.

Backed by a16z and YC, Metal is building an AI-native operating system for founders raising venture rounds. Metal brings proprietary intelligence on the venture ecosystem, enabling founders to identify the "most likely" investors, research various firms, and identify who they know that can introduce them to specific investors. More than 100 YC founders have signed as paying customers.

InferEdge builds agentic AI for the buy-side - systems that run autonomously across research, portfolio management, and risk, for equity and fixed income. The point isn't generating a generic note - anyone can do that now. For example, when earnings season hits, our agents produce the quarter's coverage in your analysts' own tone and format, matching how your desk already writes, so it doesn't need a rewrite before it's usable. We build on top of LLMs, turning raw model capability into consistent and auditable workflows, not another stalled prototype.
