J Cornelius speaking

Better products.
Smarter decisions.

Product strategy and leadership for companies that need to move forward with clarity & confidence.

Start with the real problem. Everything else follows.

Every engagement starts with understanding your problem — not your feature list, not your competitor's product, not the thing your board is excited about. Your actual problem. Once that's clear, the path forward gets simpler.

The approach is grounded in human-centered design, behavioral economics, and three decades of building real products and companies. When AI can accelerate the work, you'll see where and how. When it can't, you'll hear that too.

No fluff. No frameworks for the sake of frameworks. Just clear thinking applied to your specific situation.
