How to Find B2B Leads for Free in 2026

LinkedIn's free tier lets you search for people by title, company size, industry, and location using Boolean operators (AND, OR, NOT). A search like "VP Sales" AND "SaaS" AND "50-200 employees" can surface hundreds of qualified decision-makers in minutes. The catch: you can only view ~100 profiles per day on a free account before hitting the commercial use limit. For each lead, you then need to find their email address separately.

Hunter.io (free plan: 25 searches/month) lets you find email addresses associated with any domain. Enter a company's website and it returns all publicly indexed email patterns. Combine with a LinkedIn search and you can manually build a targeted list. At 25 searches per month, this method works for highly targeted micro-lists but doesn't scale.

Apollo offers a free plan with limited monthly exports. You can search their 275M+ contact database by title, company size, industry, and tech stack. The free tier limits you to a small number of contact reveals per month, but it's a legitimate way to test if Apollo's data quality matches your niche before upgrading.

If you're selling to local businesses (restaurants, dental practices, law firms, auto dealerships), Google Maps is surprisingly effective. Search for your target business type in a city, and you get a list with names, addresses, phone numbers, and often website URLs. From the website you can usually find the owner's name and email. It's manual, but the data is fresh.

Most industries have an association that publishes a public member directory. SHRM for HR professionals, HIMSS for health IT, NAR for real estate agents. These directories often include names, titles, company, and sometimes direct emails. They're undiscovered goldmines for niche industries where scraped databases fall flat.

Crunchbase lists every funded startup with founding team names, company details, and funding rounds. The free tier lets you browse and filter by industry, location, and funding stage. This is ideal if you sell to startups or venture-backed companies — you can identify decision-makers before they're flooded with vendor outreach.

When a company posts a job, they reveal exactly what they need right now. A company posting "Head of Sales" signals they're building out revenue — perfect if you sell sales tools or services. Filter LinkedIn Jobs or Indeed by company size, industry, and job title to find companies with active buying intent, then find the decision-maker's contact separately.

When Free Methods Take Too Long

The free methods above work — but every hour you spend building a list is an hour you're not selling. LeadVein delivers 50–500 hand-verified B2B contacts — targeted by your exact industry, title, and geography — as a CSV within 24 hours. Starting at $29.
