Tom Happ has worked on may different "triple-A" games for both PC and consoles, such as Grey Goo, Tiger Woods, and NFL Street, to name a few. He began work on Axiom Verge as a part-time hobby in March 2010. Working alone, he is responsible for all art, code, music, and game design. In April 2014, he was selected for Sony's pub fund, which resulted in him being able to work on it full time - as well as a torrential flood of media exposure, awards (GameSpot's Best of E3 2014!), and rapid progress on the game itself. He still works part-time as an engineer for Petroglyph Games in Las Vegas, Nevada.
Dan Adelman is the guy who brought games like Cave Story, Shovel Knight, Retro City Rampage, the BIT.TRIP series, and World of Goo to Nintendo platforms. He worked there for 9 years, and his name is basically synonymous with Nintendo indies; he's facilitated the launch of hundreds of titles. Business development, marketing, negotiating - all those things that indies themselves tend to be weakest in - are his expertise.
