Custom iGaming and fantasy sports software for startups and enterprises

IT Services and IT Consulting Riga, Latvia 201–500 employees Partnership

GammaStack builds custom software for iGaming, sports betting, and fantasy sports operators. The stack is modern full-stack (React, Node.js, GraphQL, PostgreSQL, AWS) with heavy graphics capabilities (WebGL, Canvas, Pixi.js), matching the real-time, animation-heavy demands of gaming platforms. Hiring is engineering-focused (18 of 21 open roles) with a seniority mix skewed mid-to-senior, but recent hiring has slowed—a signal the org may be in delivery mode or facing market headwinds.
