Hidden Brains is an AI-enabled software development and product engineering company that works with businesses through every stage of their technology journey — from consulting and strategy to development, digital transformation, modernization, maintenance, security, and compliance.

We work with startups, scale-ups, enterprises, and Fortune 500 companies, helping them build technology around the way their business actually works. Instead of forcing standard solutions into existing operations, we design and engineer software around real workflows, business rules, users, integrations, and long-term growth plans.

Whether it is building an MVP, modernizing a legacy platform, creating a new digital product, strengthening enterprise architecture, improving data foundations, or introducing AI into existing processes, our focus is on creating solutions that are practical, scalable, secure, and easier to evolve.

Idea Maker is a US based software development company headquartered in Irvine, California, with additional offices in Los Angeles and Dallas. The company builds custom software and mobile applications for organizations that need systems built to their own requirements rather than configured from a template.

Supporting services span UI/UX design and prototyping, full stack development, third party and systems integration, ongoing maintenance, and search engine optimization.

Being US based means projects are built to domestic compliance standards. Clients track progress through Slack, Loom, and ClickUp.
