About the Company
What we do
ZionStar is the AI-first education-technology engineering company behind Sublime LMS and Sublime Intelligence.
What started in 2019 as a small engineering team is now a specialized partner to universities, EdTech companies, bootcamps and training providers — building and modernizing LMS platforms on Canvas, Moodle and Open edX, student portals, Zoho CRM automation and Ruby on Rails systems.
We believe learning software should feel like modern software. So we engineer connected, intelligent ecosystems — retention prediction, engagement automation, AI guidance — that make finishing the default for every learner.
Education firstWe design for learner outcomes, not feature lists. Every decision traces back to a student who finishes.
Engineering rigorSenior teams, clean architecture, tested code. We ship education software that holds up at scale.
Genuine partnershipWe embed with your team, share your roadmap, and stay accountable to the result — not the invoice.
Trust by defaultSOC 2, GDPR and WCAG 2.1 are the baseline, in every region we serve.

Leadership
The people setting the bar.
It began with an engineering bar.
Samuel founded ZionStar around a simple conviction: education deserves software built to the same standard as the best consumer products. That conviction still sets the direction — and the bar — for everything we ship.
