We are Hitosea
A group of engineers who believe open source can change enterprise software.
Our mission
Use open-source, modular products to help teams spend their energy on what truly creates value — not building infrastructure, but shipping better products and serving more customers.
What we're doing
We build three product lines that reinforce each other: enterprise collaboration (centered on DooTask), AI & developer tools (Happy Next, eeui, DooPush), and vertical AI products (MenuRay, Qiujian, TTPOS). Every product is open-source, self-hostable, and enterprise-ready.
