Empowering Innovation: Yohei Nakajima’s Transparent AI Revolution at Untapped Capital
A Seattle-based venture capitalist is gaining an edge in the competitive tech investment landscape by embracing artificial intelligence and maintaining transparent development practices. Yohei Nakajima of Untapped Capital has positioned himself as both an investor in AI startups and a dedicated practitioner of the
technology, having begun his exploration of generative AI tools well before ChatGPT entered the mainstream in 2022.
At Untapped Capital, AI has become integral to daily operations, with Nakajima and his team utilizing various AI tools for investment sourcing, due diligence, administrative tasks, and marketing efforts. What sets Nakajima apart is his commitment to developing and testing AI projects openly, sharing his progress with the public.
One of his notable public projects includes VCpedia, a startup intelligence platform he developed through “vibe-coding” earlier this year. He also gained significant attention for Baby AGI, an
open-source autonomous agent project released in 2023. The firm has further expanded its AI toolkit with custom GPTs, including a tool called “Mean VC” designed to help startup founders refine their pitches.
This transparent approach to development has yielded multiple benefits for Untapped Capital. Beyond providing access to developer communities and helping identify emerging trends, it has positioned the firm as an active builder in the space. The strategy has even led directly to investment opportunities, as demonstrated by their investment in Wokelo, a Seattle startup they discovered while developing similar AI-powered due diligence tools.
Nakajima, who has roots in the Seattle area and previous experience with Scrum Ventures and Techstars, advocates for leadership by example when implementing AI in organizational workflows. He personally demonstrates the value of AI tools like ChatGPT to his team by sharing his interactions with the technology, which has encouraged wider adoption among his colleagues.
Looking ahead, Nakajima predicts AI will become increasingly embedded in workplace processes, eventually surpassing human output in many areas. His investment interests include AI agents and authorization, corporate AI governance, and AI-native consumer applications in sectors like gaming, film, and music.
Untapped Capital operates as a pre-seed generalist investor focused on U.S. startups, having raised $9.5 million for its initial fund. The firm has made 36 investments to date, typically writing checks between $250,000 and $500,000 for companies valued at under $10 million.
Through this combination of hands-on AI development, public building, and strategic investment, Nakajima has created a unique position for Untapped Capital in the competitive venture capital landscape, while simultaneously gaining valuable insights into the rapidly evolving AI sector.
