Tech startups have reaped the benefits of investor interest for the past two decades now. Ever since home computing truly revolutionized the information age, the real money in the business world has gone into technological innovation. Sometimes it’s something as big as the internet, or a social networking site that grows to claim the comparable population of a whole nation. At other times it’s simply a great idea that fulfills a need within a niche market. Houzz, a mobile app and website that helps people design home renovations is one such targeted idea. And as with any quality app in the mobile market, investors are paying attention. According to a recent press release, the makers of Houzz have just received $35 million in their Series C financing round.

The new investors in co-founders (and husband and wife) Alon Cohen and Adi Tatarko’s company join current stakeholders Sequoia Capital, and include GGV Capital, David Sacks of Yammer and Comcast Ventures, and Kleiner Perkins Caufield and Byers. It’s an impressive roster of investors for a startup that’s a little more than two years old. But all you have to do is turn on the television to see how huge an industry home remodeling is. And Houzz has managed to tie together business interests and social networking in a way that’s got app experts buzzing.

Houzz currently features in the neighborhood of 12 million unique users each month, which is a 450% increase in its year-over-year. Those millions of dedicated fans use Houzz as a Pinterest-esque board of images culled from the internet and their personal projects, and to research and trade ideas for projects with other users. There are forums for discussion divided by topic, as well as active boards where professional home remodelers can promote their businesses and make suggestions.

That professional element may be one of the reasons Houzz was able to pull together such an aggressive financing raise. The app is used by major design houses, contractors and architectural firms as a marketing tool. Showing off current work and answering questions posed by Houzz users allows these businesses to attract a huge amount of new customers. With more than 160,000 professionals currently using Houzz, it’s clear that this free resource is worth its weight in gold.

Folks in the remodeling business looking for something a little more full-bodied should be thrilled with the upcoming release of Houzz Pro+. It’s a marketing engine for businesses that is accessed by subscription, and offers a whole slew of new features as well as increased exposure amongst the general Houzz audience. Another significant revenue generator for Cohen and Tartarko is an advertising tool that slips targeted product campaigns in and amongst the content posted by private individuals. So if Ikea or Lowe’s has some new carpet products they’re looking to move, they can promote those offerings amongst images of carpeting projects taken and submitted by users. It’s a much more seamless way to advertise than other sites have managed to utilize, and should prove hugely beneficial to the larger brands.
