How to Find 50 Free B2B Leads in Any Niche: The DIY Method and a Faster Shortcut (2026)

A new report published by Semantic Strategy profiles Pipefire, a done-for-you cold email service built and run by Mike Lovatt through M&B Marketing SARL, a company registered in France. The report examines Pipefire's operating model, its structural differences from conventional cold email setups, and a free lead tool that anyone prospecting local businesses can use right now. We have reviewed the research and pulled out what matters most for agency owners and B2B service businesses trying to generate new client conversations in 2026.

The DIY Method: How to Pull 50 Verified Local B2B Leads for About a Dollar

Before covering what Pipefire does, it is worth knowing the manual method that underpins this kind of prospecting. Mike Lovatt published a detailed walkthrough in r/B2BSales in October 2026. It uses three tools: Claude (the desktop app or Claude Code) or ChatGPT, a DataForSEO account, and a Hunter account. Here is how it works.

Step 1. Connect Claude to DataForSEO using DataForSEO's official MCP server. Their help centre has a guide titled "Connect Claude to DataForSEO MCP". You paste in your API login and password and the connection is live.

Step 2. Ask Claude to pull businesses from Google Maps. A prompt like "Using DataForSEO, find artificial turf installation businesses on Google Maps in San Jose. Give me name, website, phone, rating and review count in a table" is enough to get started. New DataForSEO accounts receive one dollar of free trial credit, which covers a handful of searches.

Step 3. Run each website through Hunter's free plan (50 credits a month) to find the business email and verify it is safe to send to. Never skip verification. Sending to dead addresses is the fastest way to get a domain flagged.

A few things to keep in mind. Search the exact trade, not the category: "artificial turf installation" returns far cleaner results than "landscaper". Ask Claude to visit each website and confirm the business actually does the work, and to grab the owner's name from the About or home page if one is listed. Expect most inboxes to be shared (info@, office@) and write your outreach for whoever opens that inbox, not a specific name you cannot confirm.

If the city is small, widen the area. Broad trades like cafes or dentists will return more than 50 results in almost any major city. Specialist trades require a wider radius.

Lovatt's worked example is instructive. He searched for artificial turf installers in San Jose. Searching "landscapers in San Jose" returned 50 businesses. Nineteen were tree services. Only 11 mentioned turf anywhere on their site. San Jose alone did not have 50 real turf installers, so the area was widened to the Bay Area. The cleaned list: 36 real turf companies, 22 that mention turf on their own site, zero tree services. Of those 36, only 9 listed an owner's name and only 2 had a personal-looking email address. The rest were shared inboxes.

Total cost: about a dollar. A useful first test before committing to any paid contact database.

What Pipefire Does: The Free Lead Tool

Pipefire has built a free tool that replicates this process without any account setup, API connections or manual cleaning. You enter a niche and a city or state at pipefire.ai/tools/free-leads, confirm your email address, and Pipefire emails you 50 leads as both a PDF and a spreadsheet. It is free. Each person gets one list.

Each lead includes the business name, email address, owner's name and title where the business lists one publicly, phone number, Google rating, and where the business ranks on Google for the search its own customers type. That last data point is particularly useful for anyone selling SEO, paid ads or web design: you can see immediately which prospects are invisible in local search and lead with that.

The leads are found fresh the day you request them. They are not pulled from a bought or shared database. Scout, Pipefire's own lead engine, finds them in real time.

Scout applies a cleaning layer before anything reaches you. It removes chain and franchise branches, lead-generation sites, businesses that look like a match but are not really in the niche, businesses outside the specified area, duplicates, and inboxes that nobody reads for sales purposes such as careers@ addresses. The PDF shows how many listings were removed and the reason for each removal.

Every email address is checked before delivery. Addresses that bounce are removed. Catch-all domains cannot be confirmed by any checker; those are marked "risky" and listed at the bottom of the sheet so you can make an informed decision.

Specialist niches work as well as broad ones. Ask for "personal injury lawyers" or "artificial turf installers" and Scout keeps only businesses that say that is what they do. The niche filter is applied against the business's own website content, not just the category label a directory assigns.

How Pipefire Compares to Building This Yourself

The DIY method above works. It costs roughly a dollar and produces a real, clean list. But it requires a DataForSEO account, a Hunter account, a Claude or ChatGPT subscription, time to connect the MCP server, and manual judgment calls on which results to keep. For a one-off test, that is fine. For anyone running outbound consistently, the overhead compounds.

Here is where the structural differences become visible.

• Pipefire delivers leads found fresh the day you ask. The DIY method can do the same, but it requires you to run the query, clean the output and verify emails yourself. Pipefire's Scout agent handles all three steps before the list reaches you.
• Pipefire applies a niche filter in code, not by eye. The turf-versus-landscaper problem Lovatt documented is handled automatically. Scout checks each business's own website before including it.
• Pipefire marks catch-all domains explicitly. Hunter flags these too, but Pipefire surfaces them in a dedicated section at the bottom of the sheet with a plain-language explanation, which reduces the chance a first-time user sends to a risky address without realising it.
• Pipefire includes Google ranking data per lead. The DIY method as described does not produce this. For agencies selling visibility services, it is a ready-made conversation starter baked into the sheet.

Key Findings from the Semantic Strategy Report

• Pipefire serves agency owners and B2B service businesses who need a consistent flow of new client conversations without hiring a sales development representative, assembling a multi-tool stack, or risking their primary sending domain. The free lead tool is the entry point into that service.
• Pipefire delivers a complete outbound infrastructure for clients on its paid Standard plan ($497 a month flat): separate sending domains, DNS configuration (SPF, DKIM, DMARC, MX), managed mailboxes, fourteen-day warmup, fresh prospect research, copy you approve before it sends, paced sending, bounce and complaint monitoring, and drafted replies. Seven named agents, Scout, Sift, Relay, Ember, Post, Sentinel and Scribe, run the work continuously.
• Pipefire operates on a no-surprises model. The customer's own domain never sends cold email. Infrastructure spending is planned by the agent layer but never executed without approval. Nothing goes to a prospect until the customer approves it. The Semantic Strategy report notes that Pipefire states plainly it has no published customer results yet and shows its assumptions alongside every projection.
• Pipefire replaces a six-tool, six-invoice DIY stack with one flat fee. The alternative, buying domains, configuring DNS, creating and connecting mailboxes, warming them, sourcing and verifying prospects, writing sequences, and monitoring deliverability, typically involves six separate tools and a week of setup before the first email leaves the server.

Why This Matters for Agency Owners and B2B Service Businesses

If you sell SEO, paid media, web design, IT services, consulting or anything else to local businesses, your pipeline depends on being able to reach new prospects consistently. Cold email to businesses is legal in most markets when you follow the rules where you send: an easy way to opt out, a real sender address, and no misleading subject lines. Pipefire has a plain-language guide at pipefire.ai/cold-email/is-cold-email-legal if you want to check the requirements before you start.

The free list is a practical starting point regardless of whether you intend to run the outreach yourself or hand it to a service. Fifty verified, niche-filtered, fresh leads in your city tells you whether the market is there before you spend anything. If the city is too small for 50, Scout will widen the area. If the niche is too broad, you refine it. Either way, you have a real list to work from, not a guess.

Get your free list of 50 leads at pipefire.ai/tools/free-leads. Enter your niche and city, confirm your email, and the PDF and spreadsheet arrive in your inbox. One list per person, free, no card required.

If the list looks right and you want Pipefire to run the full outbound chain, the Standard plan starts at $497 a month and covers every step from domain purchase to drafted replies. The full Semantic Strategy research report is available at reports.semanticstrategy.com.
