Welcome to GoMonster Marketing, a growth-obsessed digital agency that helps SaaS founders and mobile-app builders turn traffic into recurring revenue.

We’ve quietly scaled Firebase-powered apps past $100k MRR and helped bootstrapped SaaS blogs add five-figure audio revenue streams — all without the bloated agency pricing or endless retainers.

GoMonster Marketing was started in 2019 by Alex Reyes and Sarah Kim — two ex-indie hackers who got tired of watching great products die because of bad marketing. After exiting their own Firebase-based tool for mid-six figures, they decided to help other technical founders who can build world-class software but hate (or suck at) customer acquisition.
Today, the team is still deliberately small (under 12 people) because we only take on clients and projects we can actually move the needle for — mostly no-code / Firebase app creators, SaaS tools, and content-driven products that need predictable, profit-focused growth.
