Jesse Sherlock

Director of Technology

Jesse joined OPEN in August 2022 as the Director of Technology, where he leads the development of database and data visualization tools for the building energy industry.

Jesse brings over 20 years of experience in software development, mostly in web development, distributed systems, web crawling, data pipelines and developer tools. He is passionate about code simplicity, free and open source, data privacy and mentoring the next generation of developers. Jesse converted to Clojure 10 years ago and it has ruined other languages for him.

Outside of work, he enjoys running, hiking, backpack camping, meditating, reading and spending too much time building developer tools.


Our team has decades of experience in green building innovation, software development, and business development.

With executive and management level experience in policy-making, real estate development, property management, architecture, energy modelling, product management, and business management, we have a holistic understanding of the building sector and the leverage points to create positive change.

OPEN Technologies grew out of the OPEN Green Building Society, a non-profit organization that has been developing open source software tools for the green building space since 2013. Today, OPEN Technologies and OPEN Green Building Society are affiliated organizations with a shared goal: to use data to shape a regenerative future for our cities.
