Event app Vamos is adding more functionality than crowdsourced Facebook events, plugging into services like Eventbrite, Ticketmaster, and Ticketfly. The reasoning is pretty straightforward – there are more events out there than what’s on Facebook, and plugging into paid events can generate some revenue.

I find Vamos to be one of the stickier apps out of all the apps I’ve reviewed, but it’s likely because I fall squarely into their demographic of bored 20-somethings. Their app provides an easy way to see what’s going on at the moment, and the Facebook integration gives you an easy way to see what your friends are up to.

Converse became Vamos’ first paying customer in May promoting 3 events taking advantage of their promotion suit of mobile banners, newsletters and web event pages.

Plugging into more services is something they’ve had in mind all along, but part of it comes down to wooing investors by showing some money moving through the service. The team of Swedes are located in Berlin, which offers cheap office space and great networks, but in co-founder Luis-Daniel Alegría’s opinion, Germany very difficult place for a consumer product to get investment, given that investors there prefer to invest in predictable business models. “Vamos is a product with the potential to be huge, but bigger risk. What we’ve noticed is that the more international the perspective, the easier it is to sell the story of Vamos,” he says.

But despite that, they’re still pushing. Alegría says, “we’re full of belief in that Vamos will become the go-to-source for events much like what Google is for websites today. Just like them, our engineering challenge will lie in crafting better and more personalized event results for our users.”
