Wildcard helped you to meet interesting people at (networking) events. With the app you could check in at events and view cards of the other attendees. Using the tinder swiping mechanism you could like people, and if there was mutual interest, you could message each other. We were heavily inspired by Tinder and thought that something like that, but for business use cases, would work really well. It proved to be much harder.. it was very hard to scale this product because it was focused on events that often had their own apps, and eventually made their own (similar) solutions.
We started this project started with some friends at a hackathon, and later went full time and partnered with Strangelove to grow the product. I was mostly responsible for Product and iOS engineering.
Here's a video of a very young me explaining the app:
