Finding companies running Facebook ads is one of the smartest ways to discover high-intent businesses, companies actively spending on marketing, potential clients for agencies, and product ideas that already convert.

If a company is paying for ads — they have budget.

In 2026, this process is more powerful than ever. But it’s also more competitive. Let’s break down how to do it properly.

Why This Still Works in 2026

According to Meta Platforms, more than 10 million advertisers actively use Facebook and Instagram ads globally.

Statista reports that Meta’s advertising revenue reached $134.9 billion in 2024.

That means millions of companies are testing creatives, scaling campaigns, and many are looking for optimization help. If you’re an agency, freelancer, SaaS founder, or AI video creator — this is a goldmine.

Method 1: Use Meta Ads Library (Free & Official)

The Meta Ads Library is the official transparency database.

It shows: active ads, inactive ads, creatives, ad copy, and platforms (Facebook, Instagram, Messenger).

Step-by-step:

1. Go to the Ads Library
2. Select country
3. Search by: brand name, keyword (e.g. “AI video”, “Shopify app”), or competitor
4. Filter by: active ads only, date range, platform

Real Example

Let’s say you’re an AI video agency. Search for “UGC ads”, “AI marketing”, or “TikTok creative”. You’ll instantly find brands running ads in that niche. If they’re running 20+ active creatives — they are scaling. That’s a warm lead.

Limitation of Meta Ads Library

It does NOT give you: email addresses, phone numbers, revenue estimates, tech stack, Shopify detection, or easy bulk export. So manual research becomes time-consuming. If you need 20 leads — fine. If you need 2,000 leads — not scalable.

Method 2: Search by Competitor Clusters

Instead of searching random keywords: search 1 big competitor, then analyze who advertises similar offers.

Example flow: Find a successful brand, check their ads, look at similar copy patterns, landing pages, and angles. Then search variations. This creates a “cluster map” of advertisers in that niche.

Works extremely well for ecom brands, lead gen agencies, and info product sellers.

Method 3: Find Shopify Brands Running Ads

Over 4.8 million live websites use Shopify (BuiltWith 2025 data). Many of them run Facebook ads.

Strategy: Find Shopify stores, cross-check if they run ads, contact them.

How to identify Shopify: View page source → look for “cdn.shopify.com”, use tech stack tools, or use lead databases. If a Shopify store is actively advertising — they’re a high-probability client.

Method 4: Use Lead Databases (Automated)

Instead of manually scraping the Ads Library, tools like AdsLeadz allow you to find companies running Facebook ads, filter by industry, extract contact information, export in bulk, and use unlimited Chrome extension scraping.

Key difference in 2026: Many tools show ads. Very few provide contact data. Even fewer provide unlimited scraping. This is important for agencies doing cold outreach.

Comparison: Manual vs Automated

If you’re doing outreach daily, automation wins.

How Agencies Use This in Real Life

Use Case 1 – AI Ad Creative Agency

Search “UGC skincare”. Find 120 brands running ads, 40 with 10+ creatives. Export emails, website, ads. Send: “Noticed you’re scaling UGC creatives. We produce AI-native UGC videos at 60% lower cost.” Conversion rates for warm ad-based leads are often 2–4x higher than random scraping.

Use Case 2 – Shopify App Developer

Find stores running discount campaigns and retargeting ads. Pitch upsell tools, conversion optimization, checkout extensions. They already spend on traffic. They need higher ROAS.

Use Case 3 – Ecom Product Research

Find brands running 50+ ads. If they test aggressively, product likely sells. Reverse engineer offer, hooks, and price positioning.

What to Look For (Signals of Serious Advertisers)

Not all advertisers are equal. High-intent signals:

• 15+ active ads
• Consistent ad history
• Multiple formats (video + carousel)
• Seasonal scaling
• Retargeting creatives

If they rotate creatives weekly → real marketing team. If 1 ad from 6 months ago → low budget.

2026 Trends in Facebook Ad Prospecting

• AI-generated creatives dominate
• Short-form vertical videos outperform static ads
• Brands run multi-platform campaigns (FB + IG + Reels)
• Agencies rely on automation for prospecting

According to Statista, digital ad spend is projected to exceed $870 billion globally by 2027. Meaning: more advertisers, more competition, more opportunity.

Who This Strategy Is For

Ideal for: Agencies, freelancers, SaaS founders, ecom product researchers, AI creative studios.

Not for: People looking for “get rich quick”, manual cold email spammers, businesses without outreach system.

You still need: solid offer, good email copy, CRM, and follow-up sequences.

Step-by-Step Prospecting Workflow (Pro Setup)

1. Define niche
2. Search Ads Library
3. Identify scaling brands
4. Export leads
5. Enrich data
6. Personalize outreach
7. Follow up 3–5 times

Agencies doing this consistently close 2–5 new clients per month from ads-based prospecting alone.
