← All the people Dennis builds with

Co-founder at Gantry Technologies

Mark Wagner

Mark Wagner sits at the top of Dennis’s Google Photos “People & pets” list, right after Dennis himself. The photo cluster Dennis opened for Mark runs from 3 February 2025 through 25 July 2026, capturing portraits and videos that include Christmas Day 2025. Mark is one of the first sixty names Dennis chose for his people directory.

Six years ago, Mark had a mission to build a software company. He put that goal on a YouTube live stream. Today he is a co-founder at Gantry Technologies, creating dashboards for companies who want to get the most out of their Kubernetes infrastructure.

In August 2020, during the pandemic, Dennis and Mark talked through their predictions for the next few years. They agreed to check back and see what came to pass.
