Bangalore: Facebook’s sudden buy of Instagram for a whopping $1 billion has everyone wondering ‘what next?’ and then again, it underscores the culture of innovation in the US.

Silicon Valley in itself is a place that startups can build to sell, and build some more. And this way, everybody gets what he or she wants, right? Too bad for innovative minds in China though-- if you know what we mean.

Anyhow, if you were wondering about the other tech startups that could share the same fate of Instagram and make its founders ‘insta-billionaires’, this list (as compiled by Business Insider) should help.

Here is a list of the most promising tech startups that could sell for about $1 billion, and the tech giants that would lap up their geek brains.

1. Startup: Square

What it does: Jack Dorsey’s Square, a mobile payment solution lets you access your credit card information, make payments and check your bank balance.

How much it’s valued at: $1-2 billion

Tech Giant that could buy it: Square currently has Visa as an investor, but it would be much more valuable to either this credit card company or American Express if one of them bought it—and especially since they don’t have an efficient mobile solution.
