About the Team:
Created by best friends, Geoff McIntyre and Aiden Reeves, tinyCore came from a shared vision to bridge the gap between engineering academia and industrial application.
As graduates from CU Boulder and Colorado School of Mines respectively, they have experienced firsthand the challenges new engineers face: entry-level positions demanding years of experience, and career-changers struggling to enter the field without clear pathways.
Together, they founded MR. INDUSTRIES (pronounced "Mister") guided by three core principles:
Integrity, Excellence, and Progress.
By building in the open and putting humans first, MR.INDUSTRIES is making professional embedded development accessible to everyone.

tinyCore is an engineering learning platform built around a truly open-source (open-knowledge) microcontroller, empowering the next generation of embedded engineers. Our mission is to bridge the gap between university and industry, equipping makers, students, and professionals with the tools, knowledge, and community they need to build their portfolio and bring their ideas to life. Every schematic, PCB, and line of code is open and accessible; because innovation should be for everyone.
