Ravenbrick LLC.

INITIAL LIGHT BULB:

While serving as an editor for Wired magazine in 2001, journalist/aerospace engineer Wil McCarthy wrote a story on "programmable matter"--objects that could be altered via an external input of some kind--which he followed up with a book, "Hacking Matter," published in 2003.

Later that year, Michael Barnstijn, cofounder of Blackberry maker Research In Motion, read the book and was so impressed that he staked McCarthy with $1 million to start a programmable-matter company, the aptly named Programmable Matter Corp.

Emerging as the self-described "de facto expert" on programmable matter, McCarthy left his full-time gig at Wired to focus on the startup. He first turned to his aerospace engineering background to develop a backup spacecraft sensor made of programmable matter.

However, the narrow focus and lengthy sales cycles led the company toward other commercial possibilities in the field. In 2006, McCarthy connected with serial entrepreneur Alex Burney. After consulting for Programmable Matter Corp., Burney started a second company, RavenBrick LLC, which bought Programmable Matter and targeted the construction-materials market. Burney is chief executive officer; McCarthy serves as president.

IN A NUTSHELL:

Slated for a 2008 market debut, RavenBrick's two key products, RavenWindow and RavenWall, are windows and wall panels made of proprietary "magic sauce" of filters and films, Burney said.

Both products make for much more energy-efficient buildings by reflecting light when it is hot outside and allowing light in when it is cold. RavenWall goes a step further, absorbing heat during peak afternoon times and radiating it after the sun has gone down, lowering demand for both air conditioning and heating.

"Johns Manville would view this as disruptive," Burney said. "We've always been focused on keeping the elements out, but why? Sometimes that is the opposite of what you want to do. Let's harness the energy outside and bring it inside."

Insulation holds in summer heat, added McCarthy, "increasing your disconnection with the outside. Extreme weather is not happening most of the time." He noted that a RavenWall's surface temperature holds "very steady" year-round when compared with traditional materials; a building that utilized the product on just 25 percent of its surface would no longer need utilities at all. "That means no furnace, no air conditioning," McCarthy said.

Burney said there is no need for retrofitting buildings to accommodate RavenBrick windows or walls, and contractors will not have to change their ways to install them on new projects. "It fits nicely to the existing building world," he said.

The plan calls for RavenBrick to open a 20,000-square-foot factory in Denver and be in production by spring of next year. Similar fabric and plastic products--to be used as roofing materials--are currently in development.

RavenWindows will cost $100 per square foot, versus about $80 for the most energy-efficient windows on the market. Burney said the return on investment due to energy savings will typically make up for the difference in a mere three years.

THE MARKET:

The multibillion-dollar construction materials market is especially ripe for RavenBrick's products in Europe and other regions where energy costs are high and environmental standards strong.

FINANCING:

RavenBrick released a private placement memorandum in mid-September with the goal of raising $4 million.

When transistors were invented, if someone asked what they'd be used for and you answered, 'It'll be in everything,' well, that's not a very good answer. But it's true."--RavenBrick President Wil McCarthy
