What Guidea does

Guidea, legally Theresa Neil Interface Designs LLC, is a boutique product design agency founded in 2005 and headquartered in Austin, Texas. The firm specializes in UX research, product strategy, and design for regulated and complex digital domains, with stated vertical focus across Healthcare/Digital Health, FemTech, FinTech, EdTech, and Cloud & Cognitive Technologies. Its core offering is built around a proprietary four-phase Strategic Product Design methodology (Innovate, Launch, Sprint, Scale), supported by dedicated capabilities in design research, prototyping, validation including Human Factors Engineering, design systems, and DesignOps, plus a specialized SaMD (Software as a Medical Device) service line for FDA-regulated healthcare software.

The company's business model is professional services revenue, delivered through direct enterprise sales and inside sales for mid-market and startup clients, with quote-based project pricing initiated via 30-minute discovery calls. Customer logos include 20 of the Fortune 100 (Johnson & Johnson, Humana, IBM, PayPal, MasterCard, Nestle, Capital One, Visa, Google, Express Scripts, among others) and 8 unicorns, with a self-reported 85% client retention rate across more than 300 cumulative technology clients. Marketing relies on a thought-leadership content engine (Insights blog), direct outreach, and earned credibility from awards including Forrester Wave Leader (2021), Red Dot (2023), and Inc. 5000 (2023).

In 2025, Guidea was acquired by Invene, a strategic operating company seeking to integrate fullstack healthcare AI capabilities. The firm holds a U.S. SBA Woman-Owned Small Business (WOSB) certification. As a small 11-50 employee boutique, Guidea has historically been bootstrapped with no disclosed venture or private equity funding.
