I Built a Company Relationship Search Engine (Competitors, Partners, Acquisitions, and More)

Introduction

I recently built a project called CompaniesRelated:

https://companiesrelated.com/

It’s a searchable database that helps you explore how companies are connected — including their competitors, partners, suppliers, acquisitions, investors, and broader ecosystem relationships.

The goal is simple:
make it easier to understand how companies actually relate to each other in the real world.

Why I built it

Whenever I was researching companies, I kept running into the same problem:

I would search things like:

“companies related to NVIDIA”
“OpenAI competitors”
“Stripe partners”
“Tesla suppliers”

And the results were always scattered across:

Wikipedia pages
blog posts
news articles
random lists
outdated PDFs

There was no single place where you could quickly explore structured company relationships.

So I decided to build one.

What it does

CompaniesRelated lets you:

  1. Search any company

Type a company name and instantly see related organizations.

  1. Explore relationship types

You can browse across categories like:

Competitors
Partners
Acquisitions
Investors
Ecosystem connections

  1. Discover company networks

Instead of isolated company pages, you can start to see how entire industries connect.

For example:

AI ecosystem around OpenAI
Chip supply chain around NVIDIA
Fintech ecosystem around Stripe
What makes it different

Most tools focus on:

financial data
company profiles
news aggregation

This project focuses specifically on:
relationships between companies

Not just “what a company is”, but:

“what companies it is connected to, and how”

Tech / Implementation (optional)

The system is built around structured relationship data and a simple search interface.

The goal is to keep it lightweight and fast, while allowing expansion of the dataset over time.

What’s next

This is still early, and I’m actively improving it.

Some planned improvements:

better relationship accuracy
more companies in long-tail industries
deeper ecosystem mapping
better UI for exploring networks
possible graph visualization
Feedback welcome

If you try it, I’d love feedback on:

missing companies
incorrect relationships
UX improvements
useful features
