Operator-Turned-Advisor for Deep Tech Founders

I'm Josh Geilhufe, Principal at 838 Advisory. I help deep tech companies sell to the multinationals of the world. When technology teams have solved the science but don't know how to navigate enterprise buying, they come to me.

I build the enterprise selling system for my customers: the market strategy, the partnership architecture, and the selling infrastructure. I've done it across agriculture, industrial decarbonization, bioprocessing, and advanced materials — and the structural patterns are remarkably consistent across all of them.

The commercialization playbook for discovering and developing a new biologic with one of Ag's Big 4 companies is structurally identical to selling a low-carbon cement manufacturing technology to Cemex or Holcim. Every technologist must map the buying committee, understand what a win looks like for each decision-maker, and position the technology to deliver on those individual needs. I've run that playbook across enough verticals to see the patterns that single-sector consultants miss.
