One post tagged with "ICP"

Your best customer — the one that closed fast, expanded twice, and has never complained — is not unique. There are hundreds, maybe thousands of companies that look just like them: same industry, similar size, comparable tech stack, facing the same problems.

If you could find those companies systematically, you'd have the most productive prospect list in your entire pipeline.

That's the idea behind lookalike company finding: start with your best customers, identify what makes them great, and find more companies that match. It's how Facebook Ads (now Meta) revolutionized advertising — and it works just as well for B2B sales prospecting.

Yet most B2B sales teams still build prospect lists the old way: filtering by industry and company size in a database, then hoping for the best. It's a blunt instrument. You end up with thousands of "technically-fit" companies, most of which will never buy.

This guide explains how lookalike modeling works for B2B sales, compares the tools available, and shows you how to find companies similar to your best customers — starting for free.

What Is Lookalike Company Finding?​

Lookalike company finding is the process of identifying companies that share key characteristics with your existing customers — particularly your best customers.

Instead of defining your ideal customer profile (ICP) from scratch using industry, size, and location filters, you let the data tell you what your best customers have in common. Then you find more companies that match those patterns.

How It Differs from Traditional Prospecting​

Traditional approach:

1. Define ICP manually (e.g., "SaaS companies, 50-500 employees, US-based")
2. Search a database with those filters
3. Get 10,000+ results
4. Manually sort through to find the good ones
5. Discover that most don't respond because the targeting was too broad

Lookalike approach:

1. Start with 10-20 of your best customers
2. AI analyzes what they have in common (beyond obvious firmographics)
3. Get a ranked list of companies that match, sorted by similarity score
4. Focus outreach on the highest-similarity matches
5. Get dramatically higher response and close rates

The difference is signal density. Traditional filters are binary (yes/no on each criteria). Lookalike models consider dozens of weighted attributes simultaneously, producing a similarity score that tells you exactly how closely a prospect resembles your best customers.

What Makes a Good Lookalike Model?​

Not all lookalike tools are created equal. The best ones consider these dimensions:

1. Firmographics (The Basics)​

• Industry and sub-industry (NAICS/SIC codes)
• Company size (employees, revenue)
• Location (HQ, offices)
• Founding year and growth stage

2. Technographics (What They Use)​

• Technology stack (CRM, marketing automation, analytics)
• Development frameworks and infrastructure
• SaaS tools and integrations

3. Business Model Similarity​

• Revenue model (SaaS, marketplace, services)
• Customer type (B2B, B2C, B2B2C)
• Sales motion (PLG, enterprise sales, channel)

4. Growth Signals​

• Hiring velocity (especially in relevant departments)
• Funding history and stage
• Recent news and expansions

5. Digital Presence​

• Website traffic and engagement
• Content marketing activity
• Social media presence

6. Buying Behavior Indicators​

• Previous technology purchases
• Conference attendance
• Content consumption patterns

The more dimensions a tool considers, the more accurate the lookalike matches will be.

How to Build Your Lookalike Prospect List (Step by Step)​

Step 1: Identify Your Seed Companies​

Start with 10-20 of your best customers. "Best" should mean:

• Fastest time to close — they bought without a long sales cycle
• Highest lifetime value — they expanded or renewed
• Lowest churn risk — they're actively using your product
• Best advocacy — they refer others or leave positive reviews

Don't include one-off wins or customers acquired through unusual channels (e.g., a personal connection). You want customers who bought because of genuine fit.

Step 2: Analyze What They Have in Common​

Look beyond the obvious. Yes, they might all be "mid-market SaaS companies," but dig deeper:

• What specific sub-industry? (e.g., not just "SaaS" but "vertical SaaS for healthcare")
• What growth stage? (Series A? Series C? Bootstrapped?)
• What tech stack? Use MarketBetter's Tech Stack Detector to check
• What departments are growing? (Hiring SDRs? Building a marketing team?)
• How do they sell? (PLG? Enterprise? Channel?)

Document the 5-10 attributes that your best customers share. This is your real ICP — not the one your VP of Sales wrote on a whiteboard, but the one validated by actual buying behavior.

Step 3: Run the Lookalike Search​

Enter your seed companies into MarketBetter's Lookalike Company Finder. Review the results, paying attention to:

• Similarity scores — higher is better, but don't ignore medium-similarity companies entirely
• Companies you recognize — if the tool surfaces companies you already know are good fits but haven't prospected, that's validation the model is working
• Surprises — companies you wouldn't have found through traditional filtering are where the real value lives

Step 4: Enrich and Qualify​

For your top lookalike matches, add additional qualifying data:

• Contacts: Use the AI Lead Generator to find buyer contacts
• Tech stack: Verify technology fit with the Tech Stack Detector
• Recent signals: Check for hiring, funding, product launches, or conference attendance

Step 5: Prioritize and Sequence​

Rank your final list by:

1. Similarity score (highest first)
2. Timing signals (recently raised funding, hiring relevant roles)
3. Accessibility (do you have a warm connection? Are they in your territory?)

Then build your outreach sequences — starting with the highest-priority accounts.

Why Lookalike Prospecting Outperforms Traditional Targeting​

The numbers speak for themselves:

• 2-3x higher response rates compared to broadly-filtered cold outreach (Instantly customer data, 2025)
• 40% shorter sales cycles when prospects closely match your ICP (Gong Labs research)
• 30% higher win rates on ICP-matched deals (TOPO/Gartner research)

This makes intuitive sense: if your best customer is a Series B vertical SaaS company with 100-300 employees using HubSpot and Intercom, and you find another company with those exact characteristics, your pitch is already battle-tested. You know the pain points, the objections, and the value proposition that works.

Common Mistakes in Lookalike Prospecting​

1. Using Too Few Seed Companies​

With only 2-3 seeds, the model can't identify meaningful patterns. Use 10-20 for reliable results.

2. Including Bad Customers as Seeds​

That enterprise customer who churned after 3 months? Don't use them as a seed. You want to find more companies like your best customers, not your worst ones.

3. Ignoring the Similarity Scores​

Not all lookalikes are equal. A company with 95% similarity is fundamentally different from one with 60% similarity. Prioritize accordingly.

4. Skipping Enrichment​

Lookalike data tells you which companies to target. You still need to find the right people at those companies, understand their current situation, and personalize your outreach.

5. Set-and-Forget Mentality​

Your ICP evolves as you close more deals and learn what works. Re-run your lookalike analysis quarterly with updated seed lists.
