    Our Story

    We started Olearis in 2013 with a small crew that’s still with us today. Some of us have been building together for the full 12 years-through first releases, pivots, tough launches, and big wins. That history matters: we know each other’s strengths, we ship faster, and we own the outcome together. We keep learning. We use AI in our day-to-day work (code reviews, tests, analytics, research)to move quicker and make better decisions. We’ve also launched our own startups, so we understand both sides
