Card Software

Custom software your business runs on, and the team that keeps it running.

We design, build and support the systems behind real operations. In textiles, our platform runs Sierra's 4 plants from fiber to fabric, and Aetnis traces garments back to the cotton.

What We BuildFrom idea to every day after

Founders Program

Building a new product?

We took Aetnis and Kept from first idea to launch. Founders get the same thinking that built SIERRA Nexus, from scoping to MVP to launch.

Sierra Logo

Sierra Textiles runs on SIERRA Nexus, the textile MES, ERP and data analytics platform we built, covering production from fiber all the way to finished fabric. It replaced two legacy systems, connects with Monday.com and Aetnis, and runs 4 plants and 250+ users.
