Meet the team
behind it all.

We are a vibrant and diverse team of software engineers and designers with roots at UC Berkeley and in Silicon Valley.

Who We Are

Geekbears is a boutique web and mobile development agency based in Silicon Valley. We are recognized as one of the top 25 California Web Design Companies on DesignRush. We specialize in building web and mobile apps for ambitious entrepreneurs disrupting an industry. We have assembled an agile team of software engineers and designers to help fellow entrepreneurs fulfill their visions.

Our motto, Dream. Design. Develop. was inspired by our founder and CEO Marcos Mena-Brena’s own experience starting a company from the ground up.  Like many entrepreneurs, he was full of inspiration and drive, but was hindered by technical setbacks on the road to the first prototype for SchooLinks, an education based startup he co-founded. After overcoming these technical challenges, his startup later won an incubator program (Capital Factory) and secured funding ($1.5 Million USD).

As VP of Technology for UC Berkeley’s Entrepreneurship Association, Marcos served as a mentor to entrepreneurs launching their startups, and helped them gain the skills and resources needed to plan, design and launch their products online.

“Our passion is to help ambitious and talented entrepreneurs build their visions from the ground up” says Marcos, who carries the same commitment into client work.

Geekbears was born out of this ambition, and with a roster of top talent, we have brought more than 70 client projects to life since our 2015 inception, including startups emerging from the Haas School of Business and Harvard Business School.  From engineering and design to digital marketing, we provide our clients with the tools to grow and succeed.

Whether you’re working on your MVP (Minimum Viable Product) or already have an existing product, we believe in the spirit of innovation and entrepreneurship and will work diligently to help you build and scale your product.
