Jason Lange

Chair of the Board BloomBoard

Last Reviewed: September 18, 2026

Executive Summary

Jason Lange co-founded BloomBoard in 2010 with Eric Dunn and now chairs its board, having previously led the company as Chief Executive Officer. BloomBoard began from a straightforward observation that Lange arrived at by interviewing teachers directly: schools ask teachers to differentiate instruction for every student, then send those same teachers to one-size-fits-all professional development. BloomBoard’s purpose was to invert that, using observational and evaluation data to build individualised development plans for educators. The company has since grown beyond coaching into a professional-learning platform that partners with universities, so that K-12 districts can offer teachers credential-bearing pathways as a retention tool rather than a compliance chore. Lange came to the problem from finance and education philanthropy, working in private equity and then at NewSchools Venture Fund while taking a joint MBA and MA in education at Stanford.

Career Highlights

• Co-founded BloomBoard with Eric Dunn in 2010 and led it as Chief Executive Officer before moving to Chair of the Board.
• Built the product on the premise that the principles of differentiated instruction for students should be applied to teacher development and support.
• Designed a go-to-market strategy around state mandates, giving states and districts free compliance tooling in a category that dozens of states require, which aligned purchasing to mandate timelines and shortened sales cycles.
• Grew BloomBoard from a teacher-coaching product into a platform for professional learning delivered in partnership with higher-education institutions.
• Worked at NewSchools Venture Fund, contributing to the early education-technology investment thesis for its seed fund, while completing his Stanford degrees.
• Went through the Imagine K12 education-technology accelerator in 2011 and was profiled as a member of the Young Entrepreneur Council.
• Began his career in private equity and also consulted with charter school networks before founding BloomBoard.

Professional Journey

Lange took a BA at Yale and then went into private equity. His move toward education came through NewSchools Venture Fund, a venture philanthropy organisation focused on education reform, where he worked while pursuing a joint MBA at Stanford Graduate School of Business and MA in education at Stanford Graduate School of Education. At NewSchools he contributed to the early thinking behind the organisation’s education-technology seed investing, which gave him a view across the sector’s problems rather than a view from inside a single school system. He also consulted with charter school networks during this period.

BloomBoard grew out of primary research rather than a market map. Lange interviewed educators at length about what actually obstructed them, and the recurring answer was professional development: mandatory, generic and largely useless. Since teacher quality is the strongest school-controlled determinant of student outcomes, the inefficiency was consequential. He and Eric Dunn founded BloomBoard in 2010 to build a teacher coaching platform that would take the principles of differentiated instruction, which teachers are trained to apply to students, and apply them to teachers themselves, using observation and evaluation data to generate individualised development plans. The company joined the Imagine K12 accelerator in 2011.

The commercial insight that followed was about timing rather than product. Most states mandate teacher evaluation and development tooling, so BloomBoard offered compliance functionality free to states and districts, which put the company in front of buyers at the moment a mandate forced a decision and removed much of the friction from an otherwise slow public-sector sales cycle. From that position the company expanded into a broader professional-learning platform, working with higher-education partners so that districts can offer teachers pathways that carry real credentials, which addresses retention as well as development.

Lange has since handed the chief executive role to Jill Prather-Cowart and serves as Chair of BloomBoard’s Board. He is also associated with QofAI, a platform offering AI-driven consulting and forward-deployed engineering aimed at EBITDA growth for middle-market private-equity portfolio companies, a line of work that connects back to his own start in private equity. That association is reported on his own professional profile rather than by QofAI itself, whose site names no leadership, and it should be treated as unconfirmed until a primary source establishes it.
