Three29 is a digital marketing agency for architecture, engineering, and construction (AEC) firms, law firms, and other B2B companies. We build websites that turn visitors into clients. We also run GEO (Generative Engine Optimization) and SEO programs that help firms get found in search and recommended by AI. Many clients now ask ChatGPT, Gemini, or Google's AI Mode for a shortlist before they ever visit a website. If your firm isn't on that list, your site never gets a chance. If it is, your site has to pick up the conversation AI started and give people a clear reason to reach out. That is the work we do. Our GEO and SEO team helps AI tools and search engines understand who you are, what you do, who you serve, and where. Our designers and developers build fast, accessible websites that guide visitors to the next step. When a project needs more, we build custom web and mobile apps. We also measure the results. We built Vzibl, our own AI visibility platform, to track how often AI tools recommend our clients over their competitors. It also shows which pages need work. That way you can see what is changing for yourself. Since 2010, we have launched more than 500 websites and earned a 4.9-star rating on Clutch. Clients include Scolaro Law, Mark III Construction, Bogle Vineyards, and the Sacramento Kings. Three29 is led by co-founders Kevin Howe and Joshua Hanosh. Josh speaks on GEO at industry events, including SMPS National. We have offices in Sacramento, CA and Jacksonville, FL.
