Solution Tree

What Solution Tree does

Solution Tree is a privately held educational publisher and professional learning organization headquartered in Bloomington, Indiana, with a Canadian operation in Mission, British Columbia. The company sells a portfolio of trademarked frameworks — most prominently PLC at Work® and RTI at Work™ — alongside adjacent solutions in accelerated learning, assessment, behavior, mathematics, school culture, educator wellness, and literacy (following the 2026 acquisition of Dirigo Literacy). Its primary customers are K-12 schools and districts, served through a consultative regional sales director motion that pairs customized on-site professional development with virtual coaching, keynotes, and coaching academies.

The company's business model spans four revenue streams: (1) one-time sales of more than 600 book, video, magazine, and toolkit titles via an e-commerce storefront; (2) quote-based professional development services delivered on-site or virtually under multi-year contracts; (3) institute, summit, workshop, and portable event package registrations, with 60,000+ educators attending events annually and 12,000+ PD days delivered per year; and (4) digital subscriptions through the Avanti online learning platform for individual teachers and the Global PD Teams collaborative platform for districts. Supporting go-to-market includes content marketing (blog, white papers, podcasts including 'Beyond the Pages'), webinars, social media, and a regional representative network. Recent product expansion includes the AI Ed solution and free AI Assistants targeting AI integration in K-12 classrooms, plus two completed acquisitions (Results Coaching Global in 2022 and Dirigo Literacy in 2026).
