Code over cash: How builder VCs are forging AI’s future

Imagine a world where the most effective VCs in AI aren’t only funding startups but also actively building products themselves.

You don’t have to imagine too hard because that world is here today.

Called “tinkerer VCs,” these funders are hands-on, writing code for AI algorithms and troubleshooting hardware issues in real time. Their prevalence marks a new era where deep technical expertise is as important as capital, and venture capital is evolving into a craft that demands deep involvement.

Through my work at Golden Gate Ventures, I’m seeing an increasing number of VCs taking this hands-on approach in tech ecosystems from the US to Southeast Asia.

I myself have tried this approach while leading our data-driven sourcing platform – which involves experimenting with APIs and building in-house tools to fuel machine learning models that spot top startups – while collaborating with founders on pre-launch products to provide user feedback before investment.

I think this trend is only the beginning, and tinkerer VCs will soon be the norm, not the exception. Let’s dive into why.

The rise of the builder VC

Venture capital is no longer just about writing checks. Today’s builder VCs immerse themselves in the startup journey – from prototyping new features and debugging product roadmaps to spinning up GPU clusters.

This approach is especially crucial in AI and other deeptech sectors, where capital and connections alone are not enough.

Founders increasingly look for partners who can understand model architectures, troubleshoot data pipelines, and advise them on scaling complex prototypes like those in quantum computing.

The market correction between 2022 and 2024 shattered the “growth-at-all-costs” mentality, introducing a period where capital efficiency and sustainable growth are paramount.

While valuations may stabilize in 2025, I think only startups with robust operations and the right builder VCs guiding them are likely to thrive.

As fields like AI, biotech, climate tech, and quantum computing become more complex, financial modeling without hands-on technical expertise risks missing opportunities and stalling innovation.
