Cowboy Raises $5 Million Seed for an App Store for AI Agents. What New York Developers Should Know
New York startup Cowboy emerged from stealth with $5 million in seed funding for Cowboy Cloud and the Cowboy General Store — a marketplace where developers can host and monetize AI agents without handing over code or data. Here’s what the model means for NYC founders.

NEW YORK — Building an AI agent is getting easier. Getting paid for one — without giving away the code, the API keys, or the customer data — is still hard.
That is the gap Cowboy is trying to fill. The New York-based startup emerged from stealth on Nov. 4, 2026, with $5 million in seed funding and a simple pitch: an app store for AI agents where developers build, deploy, and monetize, and buyers hire agents that run as private copies in isolated sandboxes.
Investors in the round include Nebular, Compound, Semantic Ventures, Anagram, Shine Ventures, and Uncommon Projects, along with angels Farnaz Azmoodeh (SVP of engineering at Function Health), Mats Olsen (co-founder and CTO of Dune Analytics), Aashay Sanghvi, Kevin Kwok, James Smits, and Ian Lapham, among others, according to the company blog and a BusinessWire announcement. The raise was also noted in AlleyWatch’s New York tech funding report.
From Stealth to a Live Marketplace
Cowboy was founded in 2025 by CEO Chad DePue, who previously held engineering roles at Whisper, Snap, and Uniswap, according to Dealroom, and whose path includes Uncommon Projects incubation. In a company blog post published under his byline, DePue describes hitting the same wall many New York builders know: agents that were useful on a laptop but had nowhere to live, no clean way to stay up without renting a server, and no way to hand them to another developer without handing over the code.
The product answer is two pieces that are live today: Cowboy Cloud, which runs the compute, and the Cowboy General Store, where agents are listed for hire. When someone hires an agent, Cowboy says they get a private copy in an isolated sandbox. Buyers do not see the developer’s code; neither side sees the other’s data; and the developer gets paid. The company says creators can also sell data feeds, skills, compute, and fine-tuned models — not only finished agents.
At launch, Cowboy reports more than 100 agents for hire and more than 10,000 data feeds, spanning trading agents on Hyperliquid and Polymarket as well as everyday work agents. Pricing is subscription or per-use; Cowboy handles payments and refunds. Users can sign in with Google and pay with a card. The Cowboy Chain testnet is live, with mainnet planned later this fall.
Why the Marketplace Model Matters in New York
New York’s developer and founder community is deep in AI agents — from fintech workflow bots to trading and ops tools — but monetization often forces a bad trade. Open-source contributors get adoption without revenue. SaaS wrappers get revenue but pull customer data onto the vendor’s stack. Cowboy’s published thesis is that agents need both AI’s capability and a more permanent, developer-owned runtime: build it, own it, get paid for it, without two platforms owning all of the data, compute, and intelligence.
For practical New York founders, a few product claims stand out:
- Code stays with the creator. The sandbox model is meant to let you sell the behavior of an agent without shipping the repo.
- Data isolation is part of the sale. If you are selling into finance, media, or enterprise buyers in NYC, “neither side sees the other’s data” is a diligence talking point, not a footnote.
- Idle agents should be cheap. Cowboy’s ambition — a million developers and a billion agents on a shared runtime — assumes agents spend most of their time waiting, so hosting does not require a dedicated server per bot.
- Payments are built in. Handling subscriptions, per-use fees, and refunds removes a chunk of marketplace plumbing founders usually rebuild.
None of that replaces product-market fit. A marketplace with 100-plus agents is still early. But for developers who already have agents that only run when their laptop is open, a hosted, paid channel is the missing piece the company is selling.
Takeaways for NYC Developers and Founders
If you are building agents in New York this fall, Cowboy’s launch is less about one seed round and more about a category bet: that agent monetization will look more like an app store than a consulting engagement.
- Inventory what you can list. Agents, data feeds, skills, and models are all in scope per the company. If you have a Hyperliquid/Polymarket bot or an internal ops agent, ask whether the sandbox model fits your IP and compliance needs.
- Treat data isolation as a feature, not a slogan. Ask how sandboxes are enforced, what logs exist, and how refunds work before you put customer workflows on someone else’s cloud.
- Watch the chain roadmap. Testnet today and mainnet later this fall matter if your go-to-market assumes on-chain permanence rather than a hosted SaaS alone.
- Do not confuse launch inventory with distribution. More than 100 agents is a start; distribution, trust, and repeat hiring will decide whether the General Store becomes a real channel for NYC builders.
Cowboy’s seed check will not settle who wins the agent marketplace. It does put a New York company in the race with a clear offer for developers who want to monetize without giving away the code — and for buyers who want to hire an agent without inheriting someone else’s data mess. For founders already shipping agents from Brooklyn lofts and Midtown co-working desks, that is a product category worth testing with eyes open.
