Hi—I’m Cian Brennan, Founder of Quantum Contracts

I wasn’t always on the side of Contractors, Subcontractors, and Suppliers.

For almost two decades, I worked for the very companies that engage you.

Being a subcontractor or supplier should mean building your business, not battling unfair practices or high-risk contracts.
At Quantum, we understand the challenges you face because I’ve seen them firsthand.
Too often, subcontractors unfairly lose money or go out of business because of poorly negotiated contracts.
That’s why I founded Quantum in 2019—to change the game for subcontractors and suppliers.

Our approach is simple:

We focus on helping you succeed by giving you the tools to navigate contracts with confidence.

It’s not about doing more for less; it’s about creating a system that protects your business, your margins, and your future.

We don’t ask, “How can we lock you into risky agreements?”

Instead, we ask, “How can we help you secure low-risk, fair contracts quickly and easily?”

With Quantum, it’s about proven systems, expert advice, and efficient processes—

So you can focus on what truly matters: running your business.
