According to people familiar with the matter, the US database software company Couchbase has secretly submitted an IPO application. It may go public in the first half of this year, and its valuation may reach up to 3 billion US dollars.

According to a source, the company's annual revenue has exceeded 100 million dollars. The source requested anonymity because the company's IPO documents filed with the US Securities and Exchange Commission (SEC) are confidential and have not been made public.

Couchbase was founded in 2011 and has raised $294 million from investors so far. According to PitchBook, the last time the company raised 105 million US dollars was in May of last year, when the valuation reached 580 million US dollars. GPI Capital, North Bridge Venture Partners, and Accel are all its investors.
