You've got a brilliant SaaS solution, a solid MVP, and the drive to make your startup successful. There's just one problem: "I need to start prospecting, but I can't afford $300+ a month for tools right now."

Sound familiar? As a bootstrapped founder, you're caught in the classic catch-22 – you need a steady stream of B2B leads to generate revenue, but you lack the budget for expensive lead generation tools that could help you find those leads in the first place.

The good news? You don't need to burn through your limited runway on costly subscription tools to build an effective lead generation engine.

The Bootstrapper's Dilemma: High Ambitions, Low Budget

Before we dive into solutions, let's clarify what we're talking about. B2B lead generation is the process of identifying and attracting potential business customers to your sales funnel. There are two main types of leads you'll encounter:

• Marketing Qualified Leads (MQLs): Prospects who have shown interest in your content or offerings but aren't ready to buy yet.

• Sales Qualified Leads (SQLs): Prospects who have demonstrated clear buying intent and are ready for direct sales conversations.

For cash-strapped startups, the challenge isn't just finding leads – it's finding quality leads without spending hundreds of dollars on fancy tools that promise the world but deliver variable results.

As one founder put it in a recent Reddit discussion: "I used Hunter, but it's not always accurate." This frustration with data quality in affordable tools is exactly what we're going to solve.

The Scrappy Founder's Stack: Your First Free Lead Gen Engine

Let's start with a simple but powerful combination that several successful founders swear by – the "G-L-I Method":

Google Sheets + LinkedIn + Instant Data Scraper

This zero-cost stack forms the foundation of a manual prospecting process that actually works. Here's how to implement it:

1. Identify Your ICP on LinkedIn

Start by defining your Ideal Customer Profile (ICP) – the businesses and decision-makers most likely to need and buy your solution. Then, use LinkedIn's standard search filters to find them:

• Job title: Target decision-makers (e.g., "VP of Marketing," "Head of Operations")

• Industry: Focus on sectors where your solution provides the most value

• Company size: Filter by employee count to match your target customer profile

• Location: Narrow down to your serviceable regions

Even with LinkedIn's basic free account, you can perform powerful searches to identify potential customers.

2. Scrape Your Lead List

Once you've got your search results, use the Instant Data Scraper Chrome extension to extract the information. This free tool allows you to pull public profile data into a structured CSV format with just a few clicks:

1. Install the extension from the Chrome Web Store

2. Navigate to your LinkedIn search results

3. Click the extension icon in your browser

4. Choose what data to extract (names, titles, companies)

5. Download as CSV

3. Organize in Google Sheets

Import your CSV into Google Sheets to create a structured lead list that becomes your prospecting database:

1. Create columns for tracking outreach attempts, responses, and next steps

2. Add columns for additional data you'll collect (email addresses, phone numbers)

3. Use conditional formatting to highlight high-priority prospects

Pro-Tip: Maximize the LinkedIn Sales Navigator free trial. As one founder advised, "Use your free trial for Sales Navigator, play around with its filters to find your ICPs, and build a list." Think of this as a 30-day sprint to build your foundational prospect list with access to advanced filters that aren't available in the free version.

Frequently Asked Questions (FAQ)

What is the best free way to start B2B lead generation?

The best free way to start B2B lead generation is by using the "G-L-I Method," which combines Google Sheets, LinkedIn, and a free web scraping tool like Instant Data Scraper. This simple stack allows you to identify your Ideal Customer Profile (ICP) on LinkedIn, extract their public information into a structured list, and manage your outreach process in Google Sheets without any initial cost. It's a powerful manual system for building your first prospect list before investing in paid tools.

How can I find email addresses for my B2B leads for free?

You can find email addresses for your B2B leads for free by using lead enrichment tools like Hunter.io, Lusha, or Apollo.io, all of which offer generous free plans. These tools typically provide a browser extension that works on LinkedIn profiles or company websites. Their free tiers give you a monthly credit allowance to find and verify professional email addresses, helping you build a targeted outreach list without a subscription.

What's the difference between a Marketing Qualified Lead (MQL) and a Sales Qualified Lead (SQL)?

A Marketing Qualified Lead (MQL) is a prospect who has shown interest in your marketing content but isn't ready to buy, while a Sales Qualified Lead (SQL) is a prospect who has demonstrated clear intent to purchase and is ready for a sales conversation. MQLs might have downloaded an ebook or signed up for a newsletter and need further nurturing. In contrast, SQLs may have requested a demo, indicating they are prepared for direct engagement with a sales team.

Is it legal to scrape public data from LinkedIn?

Scraping public data from LinkedIn for lead generation is against LinkedIn's User Agreement, placing it in a legal gray area. While courts have ruled in some cases that scraping publicly accessible data is not a violation of computer fraud laws, LinkedIn actively tries to prevent it. For a bootstrapped startup, manual scraping on a small scale is a common practice, but it's crucial to be aware of the platform's terms and the potential risk of account restrictions.

When should I upgrade from free B2B lead generation tools to paid ones?

You should consider upgrading to paid lead generation tools when your manual processes become too time-consuming and start limiting your growth, or when you need more advanced features and higher data accuracy. A good indicator is when you've validated your outreach process and are consistently generating revenue. At that point, the time you save by using a paid tool will be more valuable than the monthly subscription cost, allowing you to scale your efforts efficiently.
