← Talking to customers
LeadGenius: B2B lead scoring. Open-source alternative to expensive enrichment tools.

In simple English

When people sign up on your website, you need to know who is worth calling. Big sales tools charge thousands of dollars a month for this job and hide how they decide. This project is a free program you run on your own computer or server to sort sign-ups automatically. It gathers company details, scores each person using rules you write, and sends the best leads to your chat or customer database. You pay nothing for the software, but you manage the setup and keep your own data safe.

What it is

LeadGenius is a self-hosted reference implementation for B2B lead scoring and data routing. It combines a FastAPI (a modern Python framework for building fast web APIs) web application, a PostgreSQL (an open-source relational database) backend, a dbt (a data transformation tool that runs SQL models) data pipeline, and automated dashboard generation.

What it is good for

Solo founders and small sales teams who want to enrich, score, and route inbound sign-ups without paying thousands of dollars a year for commercial revenue operations software.

  • Runs locally or on a cheap server using Docker (a way to run a program inside its own sealed box, so it cannot break anything else on your server) and Docker Compose.
  • Scores leads using plain YAML (a human-readable data format used for configuration files) files that you can read and edit yourself.
  • Includes a mock mode so you can test the entire pipeline with realistic fake data without paying for live API keys.
Watch for
  • No licence is specified in the repository, which creates legal uncertainty for commercial use.
  • Requires comfort with the command line and configuration files to set up and customize.
  • Live enrichment features require separate paid accounts and API keys for external services like Apollo or Hunter.
