Sezmi has raised $17.3 million in funding, according to documents filed with the Securities and Exchange Commission.
The company raised the money from two unnamed investors, according to the filing, first reported on by the San Jose Business Journal.
Sezmi is offering a set-top box, available through retail outlets, with which subscribers can access a limited number of both over-the-air and premium channels, as well as over-the-top content.
The company is still in the process of a market-by-market rollout, with a goal of making the service nationally available.
