Industry-changing web app company needs a stand-out logo

DoubleCheck

We have created a web app designed to allow marketers to chat instantly, in real-time, with their target demographic at a fraction of the cost of traditional research. The IM style chat gives marketers the chance to DoubleCheck their concepts and media with their target market prior to launching to the public, or prior to sending their concepts to a full-blown traditional research.

Our brand will be real, grounded, down-to-earth, fast, trustworthy, smart yet not intellectual, and friendly.

Our core brand message will be around immediacy of information, low cost, and vetting ones work in real time.

We are not researchy or academic.

The target for DoubleCheck is marketing professionals who work for companies with yearly revenue of $100 million to $1 billion+. These marketers are users of technology and want to be on the cutting edge of marketing techniques. They value information and the ability to reduce risk in the decisions they make. They are creative individuals.

Secondary audience includes advertising and PR agencies.
