Our story

Sleekflow Image

In 2019, SleekFlow founder Henson Tsai talked to 500+ businesses and kept hearing the same thing: commerce was moving to messaging, but no one had a way to manage those conversations at scale. The Imperial College London graduate and two engineers started SleekFlow to fix that.

What began as a messaging platform has become an AI suite for revenue-driving conversations. In 2025, SleekFlow launched AgentFlow, giving businesses the ability to build teams of AI agents that handle the full customer journey and get smarter after every conversation.

As Henson puts it, "Businesses are no longer buying software to make their teams more efficient. They're buying AI agents that function as a digital workforce."

Leading SleekFlow's technology is CTO Gao Lei, a 20-year Silicon Valley veteran, former CTO of LinkedIn China, and PhD in distributed systems from UT Austin. Today, SleekFlow powers revenue-driving conversations for 2,000+ enterprises across 80+ countries.
