GLIDR is a product discovery and validation platform built to help your team 1) build a shared understanding of customer needs, 2) prioritize what to build, 3) calibrate your go-to-market strategy, and 4) make smarter decisions across your innovation portfolio.

In 2012, co-founders Jim Hornthal and Steve Blank discovered the need for software to power the National Science Foundation’s I-CORPS Program. Since then, we've built on our initial MVP and GLIDR is now a leading product discovery and innovation management tool.
