Zellerhaus is the studio behind everything Preston Zeller builds.

Some of it is software. Some of it is film. Some of it is harder to categorize. What connects it is a consistent obsession with the gap between what exists and what should - and the discipline to close it.

The operator track: 15 years scaling high-growth technology companies from Series A to IPO. ZoomInfo, A Cloud Guru ($2B acquisition), BatchService. Revenue infrastructure, AI workflows, GTM strategy, and the kind of growth work that shows up on a P&L.

The builder track: Founder of Psalmlog, Deadband, Lockout, and a portfolio of software ventures - each one started from a real problem, not a market opportunity.

The creative track: Producer and director of The Art of Grieving - a feature documentary seen in 40 countries, licensed to Amazon Prime, Apple TV, Tubi, and Plex. 34+ podcast appearances across growth, grief, faith, and AI. A memoir in progress.

The throughline across all of it: find the human problem underneath the surface problem, then build something for it.
