How to Approach Prime Contractors for Subcontracting Opportunities

Do Your Research First

Before you contact a prime, know everything about their federal contracts. Which agencies do they work with? What are their largest contracts? What NAICS codes do they operate under? Check USASpending.gov for their contract portfolio and FPDS for recent awards. When you reach out and reference their specific $50M VA IT modernization contract, they know you're serious — not just mass-emailing every contractor in the database.

Find Their SBLO

Every prime contractor with federal contracts over $750K has a Small Business Liaison Officer (SBLO). This person's job is to find and engage small business subcontractors. They're literally paid to talk to you. Find their contact info on SAM.gov, the company's website, or through contractor databases. An email to the SBLO will always get more traction than a cold email to a generic company inbox.

Prepare Your Pitch

Your pitch should answer three questions in under 60 seconds: (1) What do you do? Be specific — "cybersecurity assessments for federal health IT systems," not "IT services." (2) Why you? Certifications, clearances, past performance, and niche expertise. (3) Which of their contracts could benefit from your capabilities? This last point shows you understand their business, not just yours.

The Follow-Up Is Everything

Primes are busy. Your first email might not get a response — that doesn't mean they're not interested. Follow up after 7 days with a brief email referencing your first message. If you see them at an industry event, introduce yourself in person. Connect with their SBLO on LinkedIn and engage with their posts. Building a relationship takes time, but once you're in a prime's subcontractor pool, you get considered for every relevant opportunity.

What Not to Do

Don't send a 3-page email with your entire company history. Don't ask them to do the work of figuring out where you fit. Don't lead with certifications alone — every small business has certifications. And never badmouth their current subcontractors. Position yourself as an addition to their team, not a replacement.
