The solution addresses the problem of the implementation of trained models and provides the possibility for AI agents to assess their performance and learn from experience. Highlighting this milestone, Manu Sharma, CEO and co-founder of Labelbox, noted, “Every company will soon run on AI systems that learn from their own work. Getting there takes innovation at every layer, from sandbox infrastructure and the agent harness to reinforcement learning post-training. Labelbox brings those layers together in one platform, and this funding lets us push each one further, so that frontier labs and enterprises can build AI that gets better with every run.” The fresh funding will support targeted engineering research across its core offerings while expanding the go-to-market and delivery teams bringing agentic AI solutions to enterprise clients.
