Our History

Stallworth Enterprises, Inc. was founded by Rachel Stallworth as an independent technical library service for the building industry serving Northern California for over 30 years. In 1999, SEI provided an internet-based, inventory control systems called tradesources.net providing listings of over 5,000 building manufacturers with resources for points of contact. By 2006, SEI provided library services to 50 of the largest architectural and engineering firms in Northern California, New York, NY, Seattle, WA and Los Angeles, CA all of whom subscribed to tradesources.net.

From 2008 to 2012, the Great Recession hit, and the building industry was in turmoil. Libraries were starting to go away, and the market needed new technology to find the products they needed – especially with the growing commitment to sustainability and healthy building materials.

Our Mission

Stallworth Enterprises Inc. has organized and maintained reference libraries for over 30 years for some of the largest and most respected firms in the building industry. Through the development and use of online technology, SEI will become the building industry's leading internet-library management/database system. Our next generation system tool, DesignAsBuilt.com was created to serve the needs of architects, engineers, contactors, interior designers and facility planners. SEI is determined to facilitate increased use of green and sustainable products by supporting LEED, Mindful Materials, and other healthy building materials and wellness initiatives in commercial, healthcare, hospitality, as well as residential, new construction, maintenance and repair projects.
