The development of the Simple Interactions approach included contributions from many individuals and institutions from around the world. We think of this work as an open-source, public domain development. Current active developers are Dr. Junlei Li from Harvard Graduate School of Education, Dr. Tom Akiva from University of Pittsburgh School of Education, and Dr. Annie White from the Fred Rogers Institute.

Support for Simple Interactions includes grants and gifts received directly or by partner organizations originating from The Heinz Endowments, Grable Foundation, Richard King Mellon Foundation, National Science Foundation, ​Pennsylvania Office of Child Development and Early Learning, Georgia Department of Early Care and Learning, Sprout Fund, Turrell Fund, and the Vanguard Group Foundation.
