Contest Time! Build an App with IndexTank and Factual

It’s time for our new contest. The theme for this one is: local businesses! By hacking up an application that uses both IndexTank real-time custom search API and Factual’s dataset of 14M US businesses.

You could win:

  • A new iPad 2 + Smart Cover (1st place)
  • A Parrot Quadcopter Air Drone (2nd place) Check out the views from above while you hover your new toy from afar. You’ve seen the ads — now’s your chance to get one.
  • An Amazon Kindle (3rd place)
  • Plus all live apps will get a free t-shirt from IndexTank & Factual and featured in IndexTank’s App Gallery

IndexTank ( is Real-Time Custom Search API that allows you to quickly aggregate, index and search many different collections of data and APIs faster than ever.

Factual ( has amassed a monster database of all your favorite stores, restaurants, dry cleaners — heck, it’s all here!

Combine the two and POW you could be creating the new Yelp for your town, Foursquare – whatever your imagination can conjure. Mashing big data has never been easier.

What We Provide: Free Accounts and Lots of Data

You’ll get to use IndexTank’s premium plan. You get real-time search for up to 1 million documents, 1GB storage and all the benefits of snippets, geo-location and faceting. So go after large data, and show us what you can do.

Factual datasets will be limited to 1M businesses. You can create a web app of your local business, or go deep in one category and walk away with the top prize.

With IndexTank and Factual, you can search full-text across different datasets such as user created reviews or descriptions.

Don’t believe you can get something going in no time? This is what Chris Dellinger a previous contestant had to say.

“Overall I was very impressed with the ease at which I could develop an application …I went from zero knowledge to having something running in the cloud in hours!”
