![Rainmaker completes your contacts with a single mouse click [$30k API Contest]](https://img-cdn.tnwcdn.com/image?fit=1280%2C720&url=https%3A%2F%2Fcdn0.tnwcdn.com%2Fwp-content%2Fblogs.dir%2F1%2Ffiles%2F2011%2F05%2FScreen-shot-2011-05-27-at-5.13.20-PM.png&signature=36f191985c08c8db9466c428a9157023)
How many address books do you have? Personally, just with Google accounts, I have three and they are also synchronized to my Android device. Almost every entry that I have is incomplete, consisting only of a name and an email address. Sometimes you need more than that.
There are great solutions such as Rapportive and Xobni for pulling in contextual information and Googleβs newly-announced sidebar for Gmail will help as well. But for that other information, there hasnβt really been a solution until Rainmaker.
Rainmaker is a startup thatβs presently working its way through the TechStars program in Boulder, but part of its product is already live via the Rainmaker website and Chrome app. The micro-scale idea is that it pulls in publicly-listed information for your Google contacts and then syncs them back in real time. The effects are pretty astounding, if you have someone with a hefty amount of public information, but even those with light information get relevant, up-to-date details added.
Need an example? I found a good one in Barry Schwartz from Search Engine Land. Hereβs the before:


I had a chance to talk today with Dan Lynn, the CTO of Rainmaker and what the company has going on is really impressive. First off, Lynn clarifies what Rainmaker is wanting to do on a more macro scale:
βWeβre effectively building a people search engine. Weβd love to be able to provide information like βhey, we found this information about you, and we found it in these placesβ. We want to do all of this in a white-hat sort of way.β
We talked for a bit on privacy, and this is something that Lynn says is vitally important to the Rainmaker team. By the teamβs estimation, about 40% of people simply donβt know and donβt care about their information being on the Internet. Another 30% vehemently protect that information and the remaining 30% are the more social types who see the Internet as a personal branding opportunity and so they regulate the information that is available.
βWe donβt want to market fear. Weβd rather empower people to know where we found information and then have them be able to correct it or opt out of it completely.β
As for the money? Right now, youβre given 25 Raindrops for signing up and another 25 for verifying your email address. That should be a decent start for you to decide whether or not itβs worth the few cents per contact to have full information. Beyond that though, there is an API that is bringing in cash for the service. Non-commercial use of the Rainmaker API is free, and commercial use is only $.01 per match.
The team has put together a contest (details here) surrounding that API and there are over $30,000 in prizes available for it. The only rule? Build something cool. The first place winner will get $2,500 in cash, plus mentorship from TechStars, books from Brad Feld and David Cohen plus a huge list of other niceties.
Iβm about as OCD as could be when it comes to keeping my contacts tidy. Rainmaker solves so many issues for me with a single button click that Iβll be using it for everyone in my most contacted list. As we push ourselves toward more transparent online identities, I think that itβs critically important to have information at hand. The beauty of Rainmaker is that a single click of the mouse can replace countless time spent digging for information.
Give it a shot. Iβd love to hear your thoughts, even if youβre just telling me to stop being so anal-retentive.
Which wonβt happen, by the way.
