Sean Patrick Coon, product design and research leadership

I work within ecosystems of possibility, moving between human goals, the price they demand, and the solutions that might fulfill them. Design is how we whittle our way toward viability. Building used to be the slow part. When anything can be made in an afternoon, the work is deciding what deserves to be made, for whom, and when it’s enough. That’s Design.

Principles

  1. 01 / AGENTS

    Design the conditions, not the prompt.

    I design what an agent works within: the instructions it follows, the routes it takes, the gates it has to clear, and the record it leaves behind. Get those right, and the agent learns from its own work.

  2. 02 / PERSPECTIVE

    A solution has to hold up at every altitude.

    I move between human needs, market forces, business realities, and interaction details. What makes sense from one vantage point can fall apart from another, revealing assumptions worth questioning.

  3. 03 / INQUIRY

    A problem space has no fixed boundaries.

    I explore what’s known, what’s assumed, and what hasn’t yet been considered. The work often changes shape as relationships emerge and new possibilities come into view.

  4. 04 / PURPOSE

    Complexity belongs to the system.

    People have things to get done. I build tools that help them work quickly and well at a fair cost, without forcing them to shoulder complexity the system should handle.

  5. 05 / SYSTEMS THINKING

    Every solution rearranges the problem.

    I look beyond what a change fixes to understand what it sets in motion. The tradeoffs become the solution, and the consequences inform what comes next.

  6. 06 / TECHNOLOGY

    The material changes; the discipline doesn’t.

    I start with human goals, context, and scenarios to understand what a product needs to do. That interaction design work is just as essential when shaping how agents behave.

Work

I’m drawn to green fields, domains where Design is still taking shape. From the inside, they rarely look green: where there’s revenue, things seem to be working. But what’s easy to count often passes for what counts, and the work of finding the real numbers, let alone moving them, is invariably the hardest to fund.
