About #Open

#Open, also written Hashtag Open, is a dating and social networking app for people who practise or are curious about ethical non-monogamy. Its website describes it as a non-monogamous social networking experience and lists the audiences it serves as swingers, the polyamorous and the poly-curious. The app is listed on the Apple App Store as "#Open: ENM IRL".

According to a Multiamory podcast episode about the app, #Open was developed by Amanda Wilson and David Epstein, who designed it around negotiation, consent and boundaries and asked users to sign a code of conduct. The same episode says the founders had self-funded the app and had been refused advertising on some large platforms. These details date from the podcast episode and may not reflect the current ownership or funding.

The app is tied to real-world events. Its website says events are hosted through a club network across the United States and Canada, covering swinger and non-monogamy events, kink events and online events. The site reports 516,000 downloads, a figure supplied by the company.
