Built to help small businesses slow down, protect their margins, and clarify the details before they sign.
Carsen Siri
Founder, SubShield
My name is Carsen Siri. I created SubShield after digging deep into government contracting opportunities and realizing how quickly prime contractor and subcontractor relationships can turn heavily lopsided.
My background is in purchasing and procurement across national medical and industrial supply sectors. In those high-stakes environments, details meant everything. A single overlooked line item or an unverified risk-shifting clause could easily wipe out an entire project's profit margin.
That foundational experience shaped the exact way I look at federal business agreements today: slow down, isolate the liabilities, verify the compliance paths, and never assume a verbal promise is enough.
SubShield was built directly from that operational contractor mindset. It is not a law firm; it is a direct tool to organize your contract review, protect your working capital, and help you ask the right questions before you involve legal counsel and begin performance.
