How Foursquare bought my domain to steal my idea

A timeline showing how my idea made it into the hands of Foursquare

Today is May 1st, 2014— the day Foursquare announced they are creating a new service called Swarm app.

The problem is that I have had a very similar idea since 2010. You will learn on this page that I spoke to the Founder of Foursquare prior to them pursuing the same idea almost four years later.

Why did I sell the domain? The money would go towards finally funding the development of Swarm. After the sale of the domain, I would just need to secure a different URL. I previously owned, and

As a lot of web designers, developers, and other creatives would attest to, it’s not easy to get funding without proof of concept. We were in the middle of developing a beta version for the application and still are.

I created this dropmark account to share some of my files that once were secret:

Hopefully this story helps you to protect your next idea.

I email Naveen, founder of Foursquare

First off, I want to say congratulations on creating such a life-changing app as Foursquare. It’s a pleasure to know that you can be reached directly, and it’s very impressive. You’re basically living my dream. Anyways, I have an idea for an app that could possibly use Foursquare’s API or maybe even just be built into Foursquare. The problem is I don’t know programming too well, I’m just a full-time designer and frontend developer. Obviously I want to protect my idea, but if you’re interested, can I send you an NDA first? I’d love to talk to you about it and see what you think and if it’s something you might be interested in. Thanks again for your time and I look forward to talking with you!

Naveen responds to email

hmm, i usually don’t do NDAs — it’s something i learned from working with a lot of other guys in the tech industry ☺ let me know, even if at a high level, and how i might be able to help provide feedback. it’s not like i’m going to go out and do it — i have a full time job that eats up my weekends too ☺ and agreed on the dev experience: it’s hard to get started. but sometimes the only way to try something out is to just hack away and it and try to get it to work by yourself. i think you’d be surprised how much you can get done even if you only have a little background on development

I begin searching for developers

Here’s a snippet from an email to a local friend/developer:

I started calling this app “Treehouse” from the beginning since it was focused on hanging out. Now I’m leaning towards “Swarm” so it can have a theme and be fun. It’s not set in stone yet though. Here’s what I jotted down on the plane this weekend. Hopefully you can understand it and kind of get a more in-depth idea.

I receive an email from a personal email account asking about the domain

Hi Sean, I am trying to get in contact with you regarding your domain to see if you wanted to sell it. I tried emailing you directly but didn’t hear back. Are you still using the domain? Let me know! Thanks, Jon

I ask what the purpose of the domain is via email

Do you mind if I sign an NDA and know the purpose of the website? I want to make sure that the product we are building doesn’t fall within a similar scope before we agree on anything.

I receive a reply via email about the purpose of the domain

I also am in a bit of jam around any kind of information of signing an NDA as I signed a MNDA (Mutual) with my client and cannot relay any info (their rules!). I can see about signing if you want, but my thinking is that I won’t be able to. This is fairly common as its part of most consulting agreements.

My idea has been stolen by Foursquare

Was my idea patented? No. But, Foursquare did see the idea since it was clearly stated on the website ( prior to them purchasing it. Even if they have similar idea, why target my name and domain? When asked, why weren’t they willing to sign an NDA to make sure the idea wasn’t similar? Usually people will not sign an NDA if they know their idea is similar to the one discussed in the NDA. This alleviates the person of any restrictions and/or conflict that it may place on producing their own idea.

It’s myself against an enormously funded company. I work 8-5pm to make sure my bills are paid. I don’t have people throwing millions of dollars at me to back my idea.

All I can do is continue to build— build a better product.

What’s next?

We are still building Swarm.
