Hi I'm Duncan, and I am the founder OpenShiro, and lead developer of Shiro TMS, a training managment system for renewable energy companies. OpenShiro is organized as an Open Startup and Oregon Benefit Company. We have committed to publish our revenue and expenses, operate with integrity and balance our impact on people, planet and profit.

OpenShiro is built around 3 core values:

1. Empowering renewable energy companies

2. Operating in the open for public benefit

3. Creating quality software with ethics and integrity

My Story:

I am a social entrepreneur and software developer specializing in renewable energy and education technology.

In 2016 I founded HeatSpring to modernize training and certification for the building trades on topics like Solar PV, Geothermal Heat Pumps and Green Building which has reached over 100,000 professionals, offering over 200 courses maintaining a 4.6/5 average student rating.

In February 2023 I sold my ownership in HeatSpring with an intent to create a new software business focused on apprenticeships and training management for renewable energy companies.

Let's work together!
