I bootstrapped a B2B lead gen tool to my first 100 users — here's exactly what worked (and what was a complete waste of time)
I've been lurking here for a while and figured it's time to share my story since so many posts here helped me when I was starting.
Background: I was working in B2B sales and hated paying $300-500/mo for tools like ZoomInfo and Apollo just to get email addresses. Most of my team couldn't justify the budget. So I decided to build a cheaper alternative.
Month 1-2: Building (0 users)
Built the core product — B2B contact search with email verification, company data, and CSV export. Made the mistake of building for 3 months before showing anyone. Classic.
Lesson learned: I should have launched a landing page on day 1 and started collecting emails.
Month 3: Launch (0 → 12 users)
Posted on a couple of communities (not Reddit — I didn't have enough karma). Got 12 signups in the first week. 8 of them never came back after the first session.
What I did wrong: My onboarding was terrible. People signed up, saw an empty dashboard, and had no idea what to do next.
What I fixed: Added a guided first-campaign flow that walks new users through creating their first prospect list in under 2 minutes.
Month 4: The free tools strategy (12 → 58 users)
This was the turning point. Instead of spending money on ads (which I didn't have), I built 26 free browser-based tools — things like:
Cold email template generator
Email subject line grader
Spam score checker
UTM link builder
Sales commission calculator
Buyer persona builder
LinkedIn post generator
Each tool is a standalone page, fully functional with no signup wall. They're all pure JavaScript — no backend, no API calls. Each one targets a long-tail keyword that SDRs and sales people actually search for.
The play: someone Googles "email subject line tester," lands on my free tool, uses it, sees a soft CTA at the bottom ("Now find verified emails to send it to — get 1,000 free leads"), and some percentage sign up.
This single strategy brought in more users than everything else combined.
Month 5: Comparison pages (58 → 100 users)
I wrote honest comparison pages — "LeadFluxA vs ZoomInfo," "LeadFluxA vs Apollo," etc. These aren't marketing fluff. I literally list where competitors are better than me (data volume, integrations) and where I win (price, free credits, no annual contracts).
These pages rank surprisingly well because most comparison content is obviously biased and users bounce. When you're honest, people stay and read.
What I'd do differently:
Launch with a landing page and waitlist on day 1, not after 3 months of building
Build the free tools FIRST — they're the best acquisition channel and cost $0
Focus on one persona (SDRs at startups) instead of trying to serve everyone
Set up proper analytics from day 1. I was flying blind for the first 2 months
Don't build features nobody asked for. Every feature I built because "it seemed cool" got zero usage
Current state:
100+ users, mix of free and paid
Bootstrapped, no funding, profitable on hosting costs
Running the whole thing solo
What's next:
Trying Google Ads for the first time (targeting competitor keywords and free tool keywords)
Building more free tools based on what's getting organic traffic
Considering adding an API for teams that want to integrate
Happy to answer any questions about the tech stack, the free tools strategy, or anything else. And if anyone else is building in the B2B data/sales space, would love to connect.
