AE is made-in-LA, fully bootstrapped (no VC, PE, or other pesky acronyms), and specializing in developing agency-increasing products. Our software engineers and data scientists are expertly cultivated to build and maintain extraordinary products for clients. Here’s where it gets interesting… The proceeds from this client work is channeled into a fascinating array of internal skunkworks projects, some of which themselves are sold, featuring AE-built founders. That’s right, we consult AND incubate. But wait, there’s more! The proceeds of THOSE efforts are channeled in part into the development of the first brain-computer-interface operating system (BCI OS). Our mission is to ensure that when human communication is wholly digitized, the technology increases, rather than inhibits human agency. Our worldwide team of clever, witty, original-thinking super-nerds are passionate about everything from mobile apps, complex data science problems, computer vision, VR, blockchain, and almost anything else challenging and world-altering.
