Sock, a San Francisco-based company, has raised $2.8m in seed funding for its self-custodial crypto investment app. The app aims to help users build wealth through crypto investment and offers complete control over finances, including automated orders to minimize losses and take profit automatically. The funding will be used to cover operating costs, hire more technical and UX talent, and fund the go-to-market campaign. Despite being in the early stages since its launch last week, the company has seen promising growth and engagement from its community, with positive feedback received particularly in the App and Play stores. The company plans to respond to feedback and release a major app update before the end of the year.
