HoundDog.ai, Inc.

HoundDog.ai is the deterministic code context engine company. We build lightweight, Rust-based code scanners that deliver a living, code-derived view of the services, APIs, data flows, and integrations across the software organizations build.

ProtoMap: service graph for engineers and AI agents. ProtoMap maps every service, API, and field across monorepos and microservices. Engineers query their service graph in plain English and visualize the blast radius of a service, method, or field change, down to every hop and service owner. AI coding agents connect through an MCP server instead of rediscovering dependencies on every task.

Privacy Code Scanner: code-based evidence of sensitive data flows. The Privacy Code Scanner provides deterministic, code-level evidence of your applications' sensitive data flows across logs, storage, APIs, third parties, and AI integrations.
