Market mapping is one of the most time-consuming parts of deal sourcing. Here's how AI tools are making it faster without sacrificing depth.
Market mapping is where investment theses get validated or killed. A good map tells you whether a market is as fragmented as you think, whether your target has real differentiation, and where the add-on opportunities are. A bad map tells you what Google told the last three firms that looked at the same deal.
The problem is that the traditional process for building a market map almost guarantees gaps. Here's how agentic tools are changing the workflow.
The standard approach is familiar to every associate in PE: open PitchBook, search for the sector, export to Excel, supplement with Crunchbase and LinkedIn, Google the gaps, ask the management team who they compete with, and spend the next three days formatting a spreadsheet.
This process is slow for a reason. Each company requires individual research. You're reading descriptions, checking headcounts, verifying funding history, looking up investors, and trying to figure out whether a company actually fits the thesis or just uses the right keywords. Multiply that by 50 or 100 companies and you're looking at a week of analyst time for a single sector.
The bigger issue is that by the time the map is done, it's already aging. New companies have entered the space. Existing players have pivoted or been acquired. The snapshot you built is static, and the market is not.
The fundamental problem is keyword dependency. When you search PitchBook for "fleet management software," you find companies that PitchBook has tagged with those words. You don't find the company that describes itself as "connected vehicle analytics for commercial operators." Same market. Different vocabulary. Invisible to your search.
This gap gets worse in fragmented markets where there's no standard terminology. A sector like compliance automation might include companies calling themselves "regulatory technology," "policy management," "audit workflow software," or "GRC platforms." No single keyword catches them all.
Database coverage compounds the problem. PitchBook has strong venture-backed coverage but limited visibility into bootstrapped businesses and international players. SourceScrub covers the lower middle market well but misses the venture end. LinkedIn gives you headcount signals but no financials. You end up patching together three or four sources and still missing companies that aren't well-represented in any of them.
The result is a map that captures the obvious players and misses the interesting ones.
Semantic search matches on meaning, not terminology. Instead of searching for a keyword and hoping companies used that word, you describe the market in natural language and the system finds companies whose descriptions are semantically similar to yours.
In Radar, this works through a chat interface. You describe what you're mapping the way you'd describe it to a colleague: "B2B software companies that help logistics providers optimize last-mile delivery routes using real-time data." Radar converts that into a vector query and searches across millions of companies for the closest matches in meaning.
The company that calls itself "dynamic dispatch optimization for courier networks" shows up. The one that describes its product as "intelligent routing for final-mile carriers" shows up. Neither would appear in a keyword search for "last-mile delivery software," but both are clearly in the same market.
This is where most of the value is. The obvious competitors are easy to find. The non-obvious ones that use different language, serve adjacent customer segments, or approach the problem from a different angle — those are the ones that make a market map genuinely useful for investment decisions.
One of the most effective ways to build a market map is to start with a company you already know belongs in the space and find everything similar.
Similar company search uses vector similarity to find companies that are close in meaning to your anchor. If you know one fleet management company, you can find every company in the database that's doing something meaningfully similar — even if they describe themselves completely differently.
This is particularly useful for add-on identification. You have a portfolio company, and you need to map the full universe of potential acquisitions. Starting from the portfolio company's vector representation gives you a more complete view than starting from a keyword, because it captures companies that are operationally similar rather than just terminologically similar.
In Radar, you can run multiple anchors. Start with two or three known companies in the space, find similar companies for each, and merge the results. The overlap tells you where the market core is. The non-overlapping results tell you where the edges and adjacencies are. That's the kind of insight that turns a list into an actual map.
Once you have 50 or 100 companies on the map, you need data on each one. Revenue model. Customer type. Geographic focus. Key investors. Recent leadership changes. Strategic partnerships. The information that lets you segment the map and prioritize targets.
Doing this manually means opening each company's website, reading their about page, checking LinkedIn, scanning recent news, and recording what you find. At five minutes per company, 100 companies is eight hours of work — and the output is inconsistent because different analysts capture different things.
Agentic enrichment handles this differently. In Radar, you add custom columns to your company list and define what each column should answer. "What is this company's primary revenue model?" or "Who are their largest disclosed customers?" Radar researches each company and fills in the answers with source citations, across every company in the list at once.
The columns are flexible. You can ask questions that are specific to your thesis rather than being limited to whatever fields the database happens to track. A PE firm looking at veterinary services roll-ups can add a column for "number of clinic locations" that no standard database would have. A growth equity firm evaluating developer tools can add "primary programming language ecosystem" as a column. The enrichment adapts to the question.
A market map built in January is partially wrong by March. Companies raise rounds, get acquired, pivot their positioning, hire aggressively, or shut down. The map you spent a week building is a snapshot of a moment that has already passed.
The traditional response is to update the map manually on some periodic basis — quarterly, or when a new deal comes in. In practice, the map sits in a shared drive and slowly becomes unreliable until someone rebuilds it from scratch.
Monitoring solves this by keeping the map alive. Radar lets you set up ongoing monitoring for a defined market, so you get notified when new companies enter the space, existing companies change in meaningful ways, or signals appear that indicate a company is at an inflection point. The map stays current without requiring someone to manually re-run the process.
This matters most for firms running sector-focused strategies. If your thesis is industrial automation and you've mapped the space, you want to know when a new company appears that fits your criteria, not discover it six months later when a banker sends you the deck. Continuous monitoring turns a static deliverable into an ongoing intelligence layer.
The full workflow in Radar looks like this:
The result is a market map that's more comprehensive than what manual research produces, built in hours rather than days, and stays current rather than decaying in a shared drive.
The gap between firms that map markets this way and firms that are still doing it manually will only widen as the tools improve. The information advantage isn't in having access to better databases. It's in being able to see the full market, including the parts that standard searches miss, and keeping that view current over time.
Radar makes market mapping faster and more complete — from semantic search to similar company expansion to custom enrichment columns. Try it on a sector you're actively mapping or book a demo.
