If you're of the (closed) mind that two's company and three's a crowd, dating app 3nder, pronounced "Thrinder," would like you to "Kink Different." Like Tinder, but with a partner or solo, you can peruse and chat up another potential partner (or partners), and in this case if all parties approve you've got a match for your possible ménage à trois.

As Re/Code writes, the London-based app, which has options for a variety of sexual orientations and gender identities, has itself just gotten lucky to the tune of $500,000 in angel investments from undisclosed parties.

Privacy is important in such matters, of course — and Thrinder vows to protect yours. Further, really sticking it to the binary system, you can even wipe in a variety of directions. Your information is culled from Facebook, but you can choose to use a name other than the one you've got on Facebook if you choose.

The New York Post reports that Bulgarian-born Dimo Trifonov, the app's 25-year-old founder, has achieved one million downloads on 3nder, which he founded in part because of his girlfriend's expressed interest in another woman. Now, users the world over are sending about 1.2 million messages a month on 3nder — and though that's small relative to the likes of its namesake Tinder, revenue is up 500 percent since 3nder's 2014 launch. Subscribers pay about $13 month for the privilege, after all.

Tirfonov points to the relative seediness of his competition as the impetus for his clean, clear design. “I wanted to create this minimal, futuristic product," he tells Re/code. "All these sites for swingers, “have-a-threesome-dot-com” and all this kind of crap — they all use super-outdated technology. They have this scammy business plan where they create fake users to generate revenue from men, so this is how they survive... We create this thing that’s affordable, there’s nothing sexualized. We don’t have naked girls, we don’t advertise naked girls.”

Venturebeat rung a note of doubt about 3nder last year, with J. O'Dell writing as "possibly the most sex-positive person on our team" that "I think using technology for a situation as delicate as a threesome just zaps the humanity right out of it — as well as the mystery — rendering the whole experience less pleasurable for all parties involved."

You know, they used to say that about Tinder, too.
