Backing the next generation of Carnegie Mellon–founded companies.

Plaid Matrix Fund is a Carnegie Mellon University–backed seed and pre-seed venture fund investing in exceptional Carnegie Mellon founders across computing, robotics, AI, and engineering.

Supporting Carnegie Mellon University founders building category-defining businesses

Carnegie Mellon University is one of the world’s most concentrated sources of technical talent and innovation. Plaid Matrix Fund works closely with the CMU entrepreneurship ecosystem — including VentureBridge, the Swarts Center for Entrepreneurship, and the university’s alumni and research network — to help founders turn technical insight into category-defining companies.

What we do

Partnering with exceptional technical founders to build category-defining companies

Plaid Matrix Fund partners with exceptional Carnegie Mellon founders at the earliest stages of company formation. We support founders with aligned capital, experienced guidance, and access to the broader venture ecosystem—so technically ambitious ideas can grow into durable, category-defining companies.

Capital

Plaid Matrix Fund provides fast, founder-friendly seed and pre-seed capital to Carnegie Mellon–affiliated teams. Initial investments typically range from $100K to $500K, allowing founders to move quickly while staying focused on building. We invest early, with conviction, and with a long-term orientation around exceptional technical talent.

Partnership

Founders work directly with the General Partners and a trusted network of Carnegie Mellon alumni, operators, and investors who have built and supported dozens of early-stage companies. Our partnership is practical and hands-on, focused on product strategy, fundraising, hiring, and early go-to-market execution—tailored to the needs of technically driven teams.

Access

Plaid Matrix Fund helps founders build trusted relationships beyond the University. Through deep connections across the national venture and technology ecosystem—particularly in San Francisco and New York—we facilitate high-quality introductions to investors, partners, and customers as companies prepare to scale.

He went on to co-found HalloApp, raising $14 million from Sequoia and other leading investors, and has built a personal portfolio of more than 60 pre-seed investments, including Motion AI, Frame.ai (acquired by HubSpot), and Addy AI.
