GFT Ventures

Investment decisions are led by Co-Founders and Managing Partners Jeff Herbst and Greg Castle. Herbst previously spent nearly two decades as Vice President of Business Development at Nvidia, where he also ran the GPU Ventures program. Castle worked alongside him as an investment manager at Nvidia GPU Ventures before founding his own early-stage fund.

GFT Ventures is an independent firm and not a corporate venture arm of Nvidia. However, both co-founders are Nvidia alumni with deep professional histories at the company. Their investment philosophy and network reflect that tenure, and the firm actively invests in startups building on or adjacent to the GPU computing ecosystem that Nvidia dominates.

GFT leans on the co-founders' two-decade network within the accelerated computing industry. Jeff Herbst's tenure running Nvidia GPU Ventures gave him early access to hundreds of technical founding teams. That alumni and founder network now provides proprietary visibility into stealth and seed-stage companies in AI, robotics, and enterprise infrastructure.

The firm invests primarily at the seed, start-up, and early-growth stages. Its strategy supports companies from pre-product engineering through initial commercial scaling. GFT does not publicly indicate participation in later-stage growth equity or buyout transactions.

The firm's primary focus is North America, with offices in San Francisco, Palo Alto, New York, and Atlanta. While global deep-tech opportunities are within scope, GFT Ventures' portfolio concentration and sourcing activity appear oriented toward US-based frontier technology startups.

The firm does not publicly list exclusionary sectors. Based on its stated strategy, GFT is unlikely to invest in sectors distant from its computational core — such as consumer packaged goods, traditional retail, or therapeutics — but no formal negative screens have been disclosed.

GFT Ventures has not publicly disclosed specific fund closes or fundraising targets. The firm emerged publicly in 2022 with a debut early-stage vehicle. Details regarding fund size, subsequent vehicles, or current fundraising activity remain undisclosed as of mid-2026.
