Thomas Steinacher

Thomas Steinacher is the co-founder and Principal Engineer at Close, where he leads R&D. He went through Y Combinator in 2011 with Steli Efti and Anthony Nemitz, and was the technical force behind turning the internal sales tool their team built at ElasticSales into Close — writing much of the original product. Over more than a decade, he has shaped Close's engineering culture and its open source work, contributing to projects like Flask-MongoRest and quotequail used by developers well beyond Close.
