Muna Harrington, Chief Executive Officer and Co-Founder of Yellow Duck.

In his new role, Grace will lead Yellow Duck's technology strategy and product execution, building a scalable platform designed to streamline day-to-day operations for childcare providers and simplify communication with families.

At Toast, Grace was part of the engineering team that developed the technology, including POS, payments and ordering operations, which powered its growth to an over $10 billion platform. He later served as CTO of Hone and VP of Engineering at KitchenSync.

That experience is central to Yellow Duck's vision. The childcare industry faces the same operational challenges restaurants once did: fragmented systems, no purpose-built infrastructure and providers spending more time on administration than care. At Yellow Duck, Grace will build the back-office platform that changes that.

For Grace, the opportunity is as personal as it is professional. A father of three, he has experienced firsthand the friction between parents and childcare providers around scheduling, daily management and communication.

"The systems supporting families and childcare providers were not built for the way they operate today. I say that as both an engineer and a parent," said Grace. "Yellow Duck has the opportunity to give providers the infrastructure they need to run their businesses effectively, while making it easier for families to get the care they need. I am excited to build that alongside Muna."

"I went to Boston looking for the right CTO. When I met Archie, I knew I had found a co-founder," said Muna Harrington, CEO and co-founder of Yellow Duck. "He helped build the infrastructure that laid the groundwork for Toast's success. Childcare needs that same transformation. Archie has already done it once. Now, we are going to do it together."
