Attack Capital is a YC-backed venture builder and AI fund that operates as an integrated capital platform. We build AI companies from scratch in 30 days and invest in the most promising YC-backed startups across AI, vertical SaaS, robotics, and deep tech.
Traditional VC wasn’t built for AI’s rapid experimentation cycles, deep technical demands, or fast-moving product loops. Attack Capital solves this by merging:
We generate ideas, validate them, build the MVP, acquire first customers, and prepare for fundraising all in 30 days. Ready to build your AI company with the #1 YC-backed AI venture studio? We provide the capital, team, and playbook to turn your ambition into a market-leading company.

Our unique hybrid model delivers unmatched advantages.
The only AI venture studio + AI fund backed by Y Combinator, giving our founders and LPs unmatched access to one of the world’s strongest startup networks.
Unlike generalist VC funds, Attack Capital invests exclusively in AI companies, vertical AI, applied AI, agent workflows, robotics automation, and infrastructure.
Our studio model transforms raw ideas into launched companies in one month. This speed advantage attracts top founders and creates institutional-grade opportunities early.
Attack Capital companies show strong early revenue, enterprise adoption, and clear technical differentiation.
Traditional VC was not built for AI’s speed or complexity. Attack Capital’s AI fund + venture studio model delivers advantages generalist funds cannot match:
| Traditional VC | Attack Capital (YC-Backed Studio Model) |
|---|---|
Invests after the product exists | Builds companies from zero with founders |
Slow validation timelines | 30-day AI build and launch cycle |
Limited technical support | Full AI engineering, product, and GTM team |
Generic deal flow | YC-backed, AI-first, deeply vetted founders |
No structured zero-to-one process | Proven studio model of venture |
Our selection framework reduces early-stage risk and ensures only the strongest AI opportunities move forward.
Attack Capital invests in founders and companies with technical defensibility, strong market demand, and clear pathways to enterprise adoption. Every opportunity undergoes structured validation across problem severity, customer willingness-to-pay, data availability, AI feasibility, and long-term venture-scale potential. We build and invest in:
HealthTech AI companies
FinTech AI companies
Supply Chain AI companies
B2B SaaS AI companies
AI automation companies
AI agent platforms
AI for enterprise operations
Applied AI robotics
“Attack Capital is the only fund that actually builds with you. Their 30-day studio cycle gave us a working MVP, our first enterprise customer, and a Seed round in motion. No other VC moves with this level of speed, conviction, and hands-on execution.”
— Lauren Chen, Founder & CEO, SynapseOps (YC S24)
“We spoke with traditional VCs for months. Attack Capital built our entire company in four weeks. Their engineers, designers, and GTM operators felt like a true co-founding team. We wouldn’t be in YC today without their studio model and early capital.”
— Dr. Michael Ross, Co-Founder, MedVector AI (YC W25)
“I invested in Attack Capital because their hybrid model is the future of venture capital. Their studio-born companies are de-risked, their YC access is unparalleled, and their AI fund gives LPs exposure to the strongest early-stage AI deal flow in the market.”
— Sarah Kapoor, LP & Ex-VP Product at a $10B SaaS Unicorn
