Where There's a Challenge, There's a STACK Solution.

STACK takes a wrecking ball to your most frustrating preconstruction obstacles.


I’m spending hours of my day downloading and evaluating project invitations.


With STACK, you can store plans and specs from any source in one central preconstruction hub and leverage our plan and keyword search tools to quickly find the details you need to determine your interest in bidding.



I’m having difficulty keeping my team aligned using email or shared servers.


With STACK, team members can stay in sync, always work from the same plans and communicate about key project details anytime, from anywhere – in the office, out in the field or even while working from home.



I’m working late nights because I don’t have time during the day to complete bids.


With STACK, you can bid more work, in less time. Spend a fraction of the time you spend today and complete bids 10x faster so you can spend more time focused on growing your business and enjoying your down time.



I’m missing things on bids due to a slow, inaccurate paper takeoff process.


With STACK, measuring even the most complex areas, volumes and pitches is fast and simple and you never have to worry about measuring on plans with an incorrect scale. Ensure your bids are competitive and eliminate risk.


When you win, we do too.
