Hi, I’m Dan Vallentyne.

A design leader who's great with people. I work with startups, enterprises, and studios to create products and meaningful user experiences.

Good with people

Software requires aligning diverse skills and expertise across business, technology, and marketing. A natural collaborator, I work across the organization to integrate these perspectives into a shared product vision. Great software comes from great teams, and my approach builds and amplifies great teams.

AI driven

In 2022 I began using AI to accelerate the analysis of large environmental datasets. Today, the diversity of AI tools has exploded and I use them in every step of software development. From engineering and design to marketing and operations, I'm now getting more done than ever.

Real research

My background in research informs my design process—from the collection and analysis of complex data to the synthesis and communication of results. This drives a clear, rational understanding of product performance. I quantify how features serve different audiences to help teams focus on weak areas, reinforce strengths, and invest resources efficiently.

Multi-sector experience

My background is broad. I’ve worked from finance to education and from environmental research to human health. This diversity of insight and experience means I have more solutions available and produce more creative works. Through the integration of insights across industries, I deliver more competitive results.
