Raised from Clients

Geekbears is a boutique web and mobile development agency based in Silicon Valley and Mexico City. We specialize in WordPress and MEAN Stack development, and have assembled an agile team of engineers and designers to help our clients fulfill their visions.

Our motto, Dream. Design. Develop, was inspired by our CEO Marcos Mena-Brena’s own experience starting a company from the ground up. Like many young 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.

Geekbears was born out of this ambition, and with a roster of top talent, we have brought more than 65 client projects to life since our 2015 inception. From engineering and design to business development and digital marketing, we provide our clients with the tools to scale and succeed.

Whether you’re a Fortune 500 company or starting from scratch, we believe in the spirit of innovation and entrepreneurship, and will work diligently to help you build your product.
