Most contractors first engage an opportunity when the solicitation drops — far too late to influence it. Sources sought notices and RFIs (Requests for Information) are the government inviting you in earlier, while the requirement is still being shaped. Responding well is one of the highest-leverage, lowest-cost moves in federal BD.
What they are
- Sources sought — a market-research notice asking which companies can do the work, and often whether enough small businesses exist to justify a set-aside. It is not a solicitation; you can’t win an award from it.
- RFI — a broader request for information or input: capabilities, approaches, pricing ranges, draft-requirement feedback. Also not a solicitation.
Both are pre-solicitation. Their purpose is to inform the agency’s acquisition strategy — which is exactly why they matter to you.
Why responding is worth it
- It can trigger a set-aside. If enough qualified small businesses respond to a sources-sought (the “rule of two”), the agency can set the work aside — turning a full-and-open fight into one you can actually win. Your response is a vote for that outcome.
- You can shape the requirement. RFIs often include a draft SOW/PWS. Thoughtful feedback — pointing out an over-specified spec, an unrealistic timeline, or a requirement only one incumbent meets — can move the final solicitation toward your strengths.
- You get on the radar. A sharp response introduces your firm and capability to the contracting and program office before the competition starts.
How to write a strong response
- Follow the instructions exactly — answer every question asked, in the order asked, within any page limit. Same discipline as a compliance matrix, in miniature.
- Map your capability to their requirement — concrete, in their language, with relevant past performance and your NAICS + socioeconomic status front and center.
- State your small-business status clearly — it’s the data point the agency needs to justify a set-aside.
- Attach your capability statement.
- Be helpful on the requirement — if there’s a draft, give specific, constructive input, not a sales pitch.
Where it fits in capture
Sources-sought/RFI responses are an early stage of capture — they come after you spot the work in an agency forecast and before any bid/no-bid on the eventual solicitation. Treat them as relationship + shaping opportunities, not paperwork.
The bottom line
Responding to sources-sought and RFIs is how you stop reacting to solicitations and start influencing them: trigger set-asides, shape the requirement toward your strengths, and get known before the competition begins — all for the cost of a focused one-to-three-page response.
