How it works

Real scenarios, real results

1

Due diligence on potential investments

Before writing a check, understand what a company is actually built on. A startup claiming to be "AI-first" should have ML frameworks in their stack. A "cloud-native" company should be on modern infrastructure.

Example

An analyst looked up a SaaS company claiming to be "AI-powered" and found no ML frameworks, no Python, and no GPU infrastructure -- just WordPress with a chatbot plugin. Red flag avoided.

2

Benchmark portfolio companies

Compare your portfolio company's tech stack against competitors and best-in-class companies in the same industry. Identify technology gaps and areas for improvement.

Example

Compared a portfolio company's stack to 20 competitors and found they were the only one not using automated testing or CI/CD -- recommended they invest in engineering best practices.

3

Find acquisition targets by technology

Looking for companies with specific technical capabilities? Filter by technology and company size to find acquisition candidates. Export the list with decision maker contacts for outreach.

Example

A PE firm looking for Kubernetes-native companies with 50-200 employees found 180 potential acquisition targets, complete with CTO contacts for initial conversations.

4

Monitor technology trends in your thesis areas

If you invest in developer tools, monitor which tools are gaining adoption. If you focus on fintech, track which payment and compliance technologies are growing.

Example

An investor tracking the "modern data stack" thesis monitored adoption of dbt, Snowflake, and Fivetran across company sizes and found that mid-market adoption was accelerating -- confirming it was time to invest.
