We are
SPEC Toolbox

We listen, understand, and create tools that truly support your journey.

We eliminate the technical barriers so you can specify modern manufactured products

Our Values

Solve The Problem Once, Use It Many Times.

In construction, we are used to the burden of unnecessary replication costs. For example, in a building, we put effort into design and then throw it in the bin after completion. We believe a better model is to solve the problem once and turn it into infrastructure for everyone to leverage.

Grow The Pie.

Mass timber construction is still a fraction of a percentage of the market share relative to concrete. The big opportunity is to grow the pie in multiples and generate mutual value for the industry. Growing the pie takes the industry forward, cutting the pie takes things to a halt.

Equal Opportunity.

We believe that everyone around the world who is talented and wants to work hard, should have an opportunity to enter the global market. As the world becomes more connected, we can provide opportunities to the most talented individuals to make an impact on the world.

Focus on the bottleneck

The bottleneck, sometimes considered the critical path, or the root problem, is what yields the biggest opportunities for change. Therefore once identified, we believe in pursuing and solving the problem quickly and aggressively.

Be Like Hydra

Inspired by the Hydra, we embrace the mindset of growing stronger from every setback. Mistakes happen, but we always come back stronger.
