About Cobalt

Partners Matt McCormack and Zack Gelfer started The Cobalt Companies in 2003 as two guys with enough passion for building stuff to turn loose couch change into a thriving community-based building company.

We build cool, functional, and creative living spaces in Austin’s thriving urban core for folks who love the vibrant offerings of city living. We also provide construction management services to clients and their designers for custom homes, major remodeling/additions, and commercial site, shell building and tenant finish-out construction. We pride ourselves on superior quality while simultaneously maximizing value using a distinctive set of 4 core competencies.

Our Core Competencies


We’re passionate about making each project unique. During our initial evaluation, we view a particular site as an existing portrait where design and building elements can add to its best qualities to achieve optimal building potential.


We incorporate and standardize selective green building practices into every project that affords real comfort and true cost savings that our clients can recognize immediately — not at some distant point many years down the road.


We all hope to get more joy out of our everyday lives. For some, that means less time commuting and more time doing the things we enjoy. It means appreciating that sometimes less is more, and this philosophy inspires sustainable infill living.


Our team-based approach to the building process recognizes that open communication among client, architect, engineer, designer, and builder is the most important component of a successful collaborative building process.

A Word from Cobalt Home Owners

“We loved using Cobalt Companies for our home remodel and addition that got us the home of our dreams. They were on-time and on-budget which is unheard of!! Their stellar design team provided guidance that helped bring the house together beautifully. We could not be happier working with them and highly recommend them.”

Tracey + Roger L.

“I just wanted to take a minute and send you all a BIG THANK YOU note and let you know that we are very happy and excited in our new home. The house is beautiful, full of light and has a great serenity to it. You deliver something very positive to people in a very personable way.”

Hasim M.

“We really enjoyed buying a new home from Cobalt. Matt, Zack and their team were open, communicative and responsive throughout the entire process. We couldn’t be happier with our new home!”

Collin D.

“It goes without saying that working with Cobalt has been a great experience for us. We were able to stay on budget largely because Cobalt kept an eye on things so conscientiously, and because they handle the snags that come up in construction so effectively (and honorably). We are truly grateful for that.”

Adam + Meg H.

“Working with Matt and Zack at Cobalt was an overwhelmingly positive experience. We would not hesitate to build another home with Cobalt!”

Alana M.

“Hey Matt & Zack, thanks for a great project… We are so happy with the outcome for our home! You guys rock. Muchas gracias.”

LA & Michael.
