You found a contract you'd love to win. Then you read the fine print: it's a $40M multi-year job, they want five past-performance references at that size, and a full team on day one. You're a five-person shop. On paper, you're out.
Here's what most small businesses don't realize: you were never supposed to win that one alone. The company that wins it won't do all the work — it'll subcontract big chunks of it to smaller firms. Getting onto that team is one of the fastest, most underused ways into federal contracting. This guide shows you how to find those teams, using real public data — not who-you-know.
Why teaming is the small-business shortcut
Most federal work above a modest size is done by a prime contractor plus a team of subcontractors. The prime holds the contract and the relationship with the government; the subs do defined pieces of the work. For a small business, subcontracting solves the three problems that keep you out of prime contracts:
- The past-performance wall. You can't win big prime work without a track record, and you can't get a track record without winning work. Subcontracting is how you build past performance — real federal experience, on a real contract, that you can cite on your next bid.
- Capacity. You don't need to staff the whole job. You deliver your slice.
- The relationship. You get in the room with the prime and, often, the government customer — which is where the next opportunity comes from.
There's a tailwind, too: large primes are frequently required to subcontract a percentage of their work to small businesses (and to specific categories like veteran-, women-, or HUBZone-owned firms). They have small-business subcontracting goals they must hit and report. In other words, primes are often actively looking for firms like you — the hard part is just finding the right ones and reaching them.
The problem: how do you find who to team with?
This is where most owners get stuck. The advice is always "network" and "go to industry days" — real, but slow, and it depends on who you happen to meet. What you actually want is the data: which primes subcontract the kind of work I do, and who do they use?
That data exists, and it's public. Every time a prime subcontracts part of a federal contract, that prime → subcontractor relationship is reported in the government's spending data (USAspending.gov). Aggregate enough of it and you get a map of who teams with whom, by industry. That map is exactly what tells a small business who to call.
What the sub-award data actually shows
Pull the real records for an industry and the picture is strikingly clear. A few examples from actual federal sub-award data:
- In research & development, one prime subcontracted over $350 million to 54 different firms in a single window. You don't need to beat that prime — you need to be one of those 54.
- In shipbuilding, a major shipbuilder spread subcontract work across 48 different firms — valves, controls, specialty fabrication, the kind of niche work a focused small business does well.
- In defense systems, a single prime used 93 subcontractors on its programs.
Each of those is a door. And the data shows you not just that a prime subcontracts, but who it uses — which tells you whether your capability fits and gives you a concrete way to open the conversation.
The two sides of the teaming map
When you look at teaming data for your industry, there are two lists worth studying:
1. Primes who hand out subcontracts ("who to sub to"). These are the companies winning the big prime contracts and pushing work down to subs. Ranked by how much they subcontract in your industry, this is your target list for capability statements. The bigger the number and the more distinct subs they use, the more room there is for a new firm.
2. Active subcontractors ("who to team with"). These are firms already winning subcontract work in your space. Two uses: they're potential teaming partners if you want to go after a prime role together or complement each other's capabilities — and they're a benchmark, showing you the kind of firm and work that's winning, and where you could slot in.
How to actually use it to win work
Finding the names is step one. Here's the play:
1. Build your target list. Identify the primes who subcontract the most in your NAICS. Start with the ones using many different subs — they have the most room and the clearest small-business need.
2. Find the small-business liaison. Large primes have a Small Business Liaison Officer (SBLO) whose job is exactly this. Most publish a "supplier" or "small business" page. This is a warm door, not a cold one.
3. Send a one-page capability statement. Who you are, what you do, your relevant experience, your NAICS codes, and any set-aside status you hold (veteran-, women-, HUBZone-owned, 8(a)) — because that status helps them hit their subcontracting goals.
4. Reference the work. "I see you subcontract [type of work] on your [agency] programs — that's exactly what we do" beats a generic intro every time. The data gives you that specific hook.
5. Register where they look. Make sure you're in SAM.gov and, where relevant, the prime's own supplier portal, so you're findable when they need your capability.
Common mistakes to avoid
- Waiting for the RFP. Teams are formed before the proposal is due — often before the RFP even posts. By the time you see the solicitation, the prime has usually locked its team. Reach out early and stay on the radar.
- Only chasing prime work. Newer firms burn months losing prime bids they were never positioned to win. A subcontract you can actually get builds the past performance that makes the next prime bid winnable.
- Generic outreach. "We do great work, please consider us" gets ignored. Specific, capability-matched, set-aside-flagged outreach gets a reply.
- Ignoring the relationship after. One good subcontract, delivered well, is the start of a repeat relationship — primes reuse subs they trust. That's the compounding part.
Where AskTuvo comes in
AskTuvo's Teaming Finder turns the public sub-award data into a simple, industry-specific map. Tell it your NAICS codes and it shows the primes who subcontract in your space (ranked by how much they hand out), the firms active as subcontractors you could partner with, and — crucially — who works with whom, so you know exactly who to approach and how. It's built entirely from public federal records, so you're seeing real relationships and real dollars, not a guess.
You don't have to win the whole contract. You have to get on the team that does — and now you can see exactly which teams to aim for.
