Pulsatance
AI × Impact

I help mission-driven organizations figure out how to embrace AI for impact, aligned with their values — and then we build it.

Definition 1.1
pul·sa·tance
noun · Physics (archaic)
  1. Angular velocity; the rate of change of angular position with respect to time.
  2. The capacity to pivot direction without losing velocity: maintaining forward energy while reorienting trajectory.

Etymology: From Latin pulsare (to beat, to strike) + -ance (state or quality of). Mid-19th century term largely superseded by "angular velocity" in modern usage.

On the problems I solve

Helping visionary organizations move faster and scale their impact.

Our news cycles and social media are filled with AI hype, but most organizations haven't experienced the revolution and fear they are missing out. The models and tools have matured drastically in the past several months, creating enormous opportunity for organizations that can wield them. The hard part is knowing where to start without wasting time.

I help ambitious organizations figure out how to embrace AI to scale their impact without sacrificing their values.

The work is concrete. It starts with a needs assessment: sitting with your team, understanding what they actually do all day, and finding where these tools fit and where they don't. Then technical recommendations — what to buy, what to build, what to skip. Then training, onboarding, and custom tooling to meet your needs: workshops tailored to your team, software development and agentic workflows built for the nuances of your work.

Twenty years of work across science, technology, nonprofits, and philanthropy, plus daily hands-on practice with the latest tools — I've been the person adopting them and the person building them. And I bring all of it to your organization's toughest challenges.

On the author

Justin is deeply curious about how technology can advance science and serve the public good, and eager to share what he's learned. The curiosity and the generosity are backed by more than 20 years of work where science, technology, and the public good meet: shaping product, grantmaking, and research strategy at the Chan Zuckerberg Initiative, scaling open data generation and sharing at the Allen Institute, and studying bird brains as a "full stack" neuroscientist (hardware, software, bench) at UCSD. Along the way, he has helped launch nonprofits and startups in the same territory.

These days he builds with AI tools every day — agent workflows, skills, evaluation harnesses for the messy judgment calls in between — and teaches teams to do the same. He is known for moving comfortably between the lab, the boardroom, and the codebase, and for finding clear direction in problem spaces that don't yet have a name.
