B2B Prospect List: How to Build One for the Space Industry
TL;DR: A good B2B prospect list for the space industry starts with a tight definition of your ideal account, not a big download. Define the segment, size and trigger events that make a company a fit, then build the list from free public sources like USAspending.gov, SAM.gov, conference exhibitor lists, industry news and LinkedIn (researched by hand, not scraped). Add the buying roles for each account, score accounts by fit and timing, and keep everything in a CRM so the list stays clean and useful.
Key takeaways
- Quality beats size: a focused list of well-matched accounts outperforms a large generic one.
- Define fit and trigger events before you start collecting names.
- Free public sources go a long way in the space industry.
- Respect platform rules and email laws from the start.
Why does a B2B prospect list matter in the space industry?
The space market is small and specialized. Your real buyers may number in the hundreds, not the hundreds of thousands. Every account you contact should be a genuine fit, because the same people meet at conferences, talk to each other and remember who wasted their time.
A good list also makes everything else work better: outreach, ads, events, content and partnerships. Our guide on how to get leads for a satellite company shows how prospecting fits with other channels.
How do you define your ideal accounts?
Start with a short written profile:
- Segment: satellite operators, launch providers, primes, ground segment, EO analytics, government programs.
- Size and stage: startups, growth companies or large enterprises.
- Geography: where you can sell and deliver, including export-control limits.
- Needs: the problem you solve and the signs that an account has it.
- Trigger events: funding rounds, contract awards, new programs, launches, hiring sprees or leadership changes.
Look at your best current customers. What do they have in common? Our guide to lead qualification for space companies covers how to turn that into criteria.
Where can you find free data for a B2B prospect list?
Government spending and contract data
USAspending.gov describes itself as the official source for spending data for the U.S. Government. Under the federal transparency law it cites, federal contract, grant, loan and other assistance awards over $25,000 must be displayed on a public, searchable website. You can search awards by agency, recipient and keyword to find companies already winning work in your area, and to spot primes that may need suppliers.
SAM.gov's contract opportunities lists federal procurement notices, including pre-solicitations, solicitations and awards. Following notices in your area shows which programs are active and who is bidding.
For defense innovation, SpaceWERX uses SBIR/STTR funding as the Space Force's innovation arm, and its topics show where the Space Force wants new capabilities. See our guides on how to sell to Space Force and how to sell to NASA.
Conferences and events
Exhibitor and speaker lists from industry events are some of the best prospect sources in the space industry. Our space industry conferences and trade shows page lists events to start with.
Industry news
Funding, contract and launch announcements are trigger events. Track trade publications and add companies when news makes them a fit. Our breakdown of Space Force demand signals shows how to read news for sales opportunities.
LinkedIn, researched by hand
LinkedIn is useful for finding the right people at each account, but research it manually. LinkedIn's User Agreement prohibits using software, scripts, robots, crawlers, browser plugins or similar tools to scrape or copy the Services, including profiles.
Partners and primes
Prime contractors, integrators and distributors can lead you to their suppliers and customers. See our guide to selling to prime contractors.
How do you find the right people at each account?
Space deals usually involve several roles. For each account, try to identify:
- Economic buyer: the person who owns the budget.
- Technical evaluator: engineers or program leads who judge fit.
- Users: the team that will work with your product.
- Procurement or contracts: who manages the buying process.
- Champion: someone who wants the problem solved and will push internally.
You don't need all of them on day one. Start with one or two, then expand as conversations grow.
How do you score and prioritize accounts?
Use a simple two-part score:
| Factor | What to look for | Score |
|---|---|---|
| Fit | Segment, size, needs, geography | 1–3 |
| Timing | Recent trigger event or active program | 1–3 |
Accounts scoring high on both get personal outreach first. High fit but low timing go into nurture. Low fit accounts come off the list.
How do you keep a B2B prospect list clean?
Store your list in a CRM, not a spreadsheet that goes stale. Track:
- Account details: segment, size, location, source and score.
- Contacts: role, how you found them and consent status.
- Trigger events with dates.
- Activity: who contacted them, when and what happened.
Review the list regularly, remove companies that no longer fit and update contacts who change jobs. Our space startup CRM guide and comparison of the best CRM for space startups can help you pick a tool.
What rules apply when you contact prospects?
Different countries have different rules for business email. In the UK, for example, the ICO's guidance on electronic mail marketing says you can email corporate bodies, but sole traders and some partnerships are treated as individuals, and it recommends keeping a "do not email" list of businesses that object. Check the rules for every country on your list, and include opt-outs in every message.
What does a first prospect list look like?
A hypothetical example for a ground station software startup:
- Ideal account: small and mid-size satellite operators with growing constellations.
- Sources: recent launch announcements, conference exhibitor lists and public award data.
- First list: 60 accounts, each with one technical and one business contact.
- Scoring: 20 accounts with recent launches or funding get personal outreach first.
Sixty well-chosen accounts are plenty to start learning what messages work.
Where does prospecting fit in your wider plan?
A prospect list feeds outreach, ads, events and content. Our space industry lead generation page covers the channels, and our space marketing guide shows how prospecting fits into a complete marketing system.
What B2B prospect list mistakes should you avoid?
- Buying large generic lists that don't match your buyers.
- Scraping LinkedIn or other platforms against their rules.
- Skipping the ideal account definition.
- Ignoring trigger events and timing.
- Letting the list go stale.
