Maxim AI
End-to-end AI evaluation platform with pre-production agent simulation and production observability
Description
Short Intro: Maxim AI is a proprietary AI development platform built by H3 Labs Inc., founded in 2023 by Vaibhavi Gangwar and Akshay Deo, both of whom worked at Google and Postman. The company raised a $3M seed round in June 2024 from Elevation Capital, alongside angel investors who are among the founding teams of Postman, Chargebee, Razorpay, and Groww. Maxim operates from Mountain View, California with an engineering office in India and had 34 employees as of April 2026.
Key Capabilities:
Agent simulation engine that tests multi-turn AI agent behavior across hundreds of user personas and scenarios before production deployment
Closed-loop Data Engine that routes production failures into evaluation datasets and simulation scenarios
LLM-as-judge, deterministic rule, and human-in-the-loop evaluators configurable at session, trace, and span level
Pre-built evaluator store including third-party evaluators from Google Vertex and OpenAI
Prompt Playground++ with version control, visual editing, and side-by-side prompt comparison
Bifrost LLM gateway with automatic failover, MCP integration, and native observability
Real-time production alerts routed to Slack, PagerDuty, or webhooks
SDK, CLI, and webhook integration for connecting existing applications without code changes
