Jonathan Leftwich

Director of Engineering

Guillermo joined Untapped at a unique inflection point: we were shedding the technical debt of our Seed days and required a leader that not only understood the complexity of our code base, but had a vision for how we could build and actualize as we relentlessly pursued our mission. Uninterested in ego or the politics of a growing organization, Guillermo rallied the team, got to work and transformed the way we build at Untapped.
