Moonbounce, the AI control engine that ensures systems behave exactly as designed at any scale, launched with $12 million in funding. Lead investors include Amplify Partners and StepStone Group, with participation from angel investors PrimeSet and Josh Leslie, former CEO of Cumulus Networks and Gremlin.

As generative AI scales across industries, traditional content moderation approaches based on retroactive review, rigid policies, and manual oversight cannot keep pace with systems that are making thousands of decisions per second. Operational, reputational, and regulatory exposure grow alongside a business in the face of moderate uncertainty. Moonbounce closes that gap with its patented control engine that converts content policies into consistent, predictable AI behaviour.

“Most companies know what they want their AI or platform to do. The hard part is making sure it actually does it – every time, without exception. That's the problem Moonbounce solves,” said Brett Levenson, Co-founder and CEO of Moonbounce. “We give teams precise control over behaviour at the moment decisions are being made, so they can focus on growth instead of firefighting.”

Moonbounce is already used by customers across dating platforms, AI chat applications, and generative content sites, including Civit.ai and Dippy. The platform has processed 1T+ tokens across a customer base of 250 million monthly active users, evaluating 50 million pieces of content daily. Teams can develop, test, and deploy content policies in days or weeks instead of months without extensive custom engineering.

The team is led by Brett Levenson, former head of Meta’s Integrity unit, alongside co-founder and CTO Ash Bhardwaj, previously an engineering leader at Apple who built large-scale cloud and AI infrastructure across the company’s core offerings.

“Content moderation has always been a problem that plagued large online platforms, but now with LLMs at the heart of every application, this challenge is even more daunting,” said Lenny Pruss, General Partner at Amplify Partners. “We invested in Moonbounce because we envision a world where objective, real-time guardrails become the enabling backbone of every AI-mediated application.”
