According to Chen, there are six primary reasons why investors don’t fund dating startups. While he notes that there are very exceptions to those points (like Tinder and Coffee Meets Bagel), the majority of dating startups are affected. Here are six reasons why investors don’t fund dating startups:

1. Built-In Churn

According to Chen, dating startups have churn rates (the rate at which users stop subscribing to or using a product) of 20 to 30 percent. And, what makes it worse, because of the nature of dating startups (primarily: to help people find others to date and get into relationships with), there’s a built-in churn; naturally, once someone finds the “love of their life”, there’s no longer any reason to use the dating startup’s services.

2. Dating Has a Shelf-Life

Hence the second issue with dating startups: they have a limited shelf-life; no one is looking for dates forever. There’s also limited scope in shareability because most people would rather not invite their friends onto a dating app or let the world know that they’re still single.

3. Paid Acquisition Channels are Expensive

Chen notes that dating startups have historically depended on paid acquisition channels to drive user growth – and it’s a trend that continues to this day. However, it’s a costly and unsustainable strategy; the only way it would ever really work out is if the company managed to get itself a low enough churn rate while also generating a lot of revenue from each user (which, honestly, is unlikely).

4. City-by-City Expansion Sucks

Dating startups are still largely reliant on local marketplaces, and launching the product from one market to the next is costly.

5. Hard to Exit

Most successful dating startups inevitably get acquired by IAC. From Match and OKCupid to Tinder and HowAboutWe, IAC has acquired them all. Outside of that, it’s difficult for dating startups to make an exit. Chen does note that this may be more a result rather than a cause of disinterest from investors.

6. Demographic Mismatch with Investors

Simply: dating is a more a problem for Millennials; most investors simply don’t match (punny). According to Chen, most investors (the ones who actually write the checks) are already married and have kids – there’s a large disconnect between what dating startups are pitching and what investors see as actual needs. So, yeah, your dating startup probably sucks and likely won’t get funding (or will get very little funding). You can read the full post from Andrew Chen on his blog.
