About us

Richard Crowley founded Source & Binary in 2020 as a consultancy and began development of Substrate to codify the best AWS architectures he’d used leading operations engineering at Slack for six years plus a few patterns he wishes he’d implemented earlier.

Travis Cole joined Source & Binary in 2023 to transform the company from a consultancy to a product company centered around Substrate. He led the network and datacenter engineering teams at Square, the SRE team at Segment, and the cloud infrastructure team at Confluent over the previous decade.
