What it does
Prospector builds a lookalike fingerprint from a reference company and returns the rest of the Mergr universe that matches it. The fingerprint isn't just "same sector" — it includes the niche specialty terms that distinguish a real peer from a vague sector match (e.g., sheet metal and commercial HVAC, not just industrial services).
Use any reference: a portfolio company you already own, a target you're chasing, a competitor you want to map around, or a prospect you found on LinkedIn. Prospector accepts both Mergr-listed companies (autocomplete search) and off-database companies (paste a description; the tool extracts the specialty terms for you).
When to use it
Source add-on acquisitions for a platform. Filter to PE-backed companies in the same niche, owned by smaller sponsors, held 2+ years.
Build an M&A target list around a thesis. "Show me companies that look like our last deal, but unowned or held by a tired sponsor."
Scout roll-up activity in a category. Filter by Has Acquired in the last 12–24 months to find the consolidators.
Generate net-new outreach for BD or sales. Drop in your best existing client; get a ranked list of companies that resemble them.
Map a competitive set or peer group around any company in seconds.
How to use it
Prospector accepts two reference modes — pick one, then refine the chips.
Pick a Mergr-listed reference
Start typing a company name in the Pick a Mergr-listed company box. Choose a match. Prospector reads that company's profile, runs its description and press releases through Claude to extract niche specialty terms, and pre-fills the full criteria strip: sector, specialty, geography, and current ownership state.
This is the fastest path when your reference is already in Mergr.
2. Describe an off-database company
For prospects, competitors, or targets that aren't in Mergr, paste a short description into the Describe a company box.
Example: Acme HVAC Inc — commercial HVAC services for office buildings andschools in the Midwest. Specializes in chiller maintenance and emergency repair.
Click Parse. The tool extracts 3–5 narrowing specialty terms and seeds the criteria. You can edit any chip after.
3. Refine the criteria
Everything in the criteria strip is editable. Changes re-run the search automatically.
Sector — broad industry. Add or remove to widen/narrow.
Specialty — the niche terms that actually narrow the pool. This is where Prospector earns its keep; spend most of your tuning here.
Geography — countries or regions where the company operates.
Ownership — multi-select: PE-backed, Public, Private/Independent, Corporate-owned, etc. Picking PE-backed exposes three sub-filters including Owner Size, Hold Age, Owner HQ
Once everything looks good select Find Lookalikes.
Reading the results
Each result row shows:
Match score — how closely the company aligns with the reference fingerprint, based on sector, specialty overlap, ownership, and geography.
Reasons — the specific chips that drove the match.
Ownership badge — current owner and hold age (when applicable), so add-on candidates are easy to spot.
Profile link — opens the Mergr company page.
Two view modes:
By Company — flat ranked list (default).
By Sponsor — groups results under their PE owner, useful when you're hunting platforms with multiple add-on candidates or trying to spot a roll-up in progress.
Sort by Score (default) or Most Recent (recency of last transaction event). Download visible results as CSV for your pipeline or CRM.
Tips
The Specialty field is everything. Generic terms like software or services won't narrow the pool. Use 2–3 niche terms that actually distinguish the business.
Add-on hunting recipe: PE-backed + Owner Size = Small/MM + Hold Age 2+ years. This is the classic platform-fatigue window.
Roll-up hunting recipe: Activity = Has Acquired + Last 12 months. Surfaces the active consolidators in a category.
Net-new BD recipe: Leave ownership open, focus on Specialty + Geography. You're looking for fit, not deal status.
Use the off-database mode liberally. You don't need a Mergr profile to start — a two-sentence description gets you 80% of the way there.
Reset link (top-right of the criteria header) clears everything and starts you over.
FAQ
Q: How is Prospector different from Buyer Match?
Buyer Match starts with a target and finds *acquirers*. Prospector starts with a reference company and finds lookalike companies (targets, peers, prospects). Different question, different tool.
Q: Why isn't a company I know is a peer showing up?
Two common reasons. (1) The specialty chips are too narrow — try removing one. (2) An ownership or activity filter is excluding it. Toggle Ownership to "Any" and see if it appears.
Q: What's the "By Sponsor" view for?
It groups lookalikes by current PE owner. Useful for spotting platforms with multiple add-on candidates under the same sponsor (a roll-up in progress), or for understanding which sponsors are most active in a niche.
Q: Does the score mean two companies are economically comparable?
No — Prospector is a similarity score, not a comparables style score. It tells you "this company resembles the reference," not "this company trades or is valued at the same multiple."
