Both original showrunner/developer Drew Goddard and showrunner Steven S. DeKnight were writers for Mutant Enemy, production company of Joss Whedon. Both Goddard and DeKnight wrote for Whdon's shows Buffy the Vampire Slayer and its spinoff, Angel. All three are, as of 2015, developing Marvel properties; The Avengers: Age of Ultron, The Sinister Six, and Daredevil for Whedon, Goddard, and DeKnight, respectively. Daredevil and The Avengers are property of Marvel Studios and exist in the Marvel Cinematic Universe (MCU) while The Sinister Six is a spinoff of Sony's, currently, abandoned The Amazing Spider-Man series. As of the deal made between the two studios on February 2nd, 2015, Spider-Man, along with all of his side characters, will become canon in the MCU. Whedon, Goddard, and DeKnight are now, again, contributing to the same intellectual property.
