Buying a Browser Extension Business business

Published September 1, 2026 · Reviewed by The Diligence Standard Team · Updated September 11, 2026

Install count can overstate value if active use is weak or permissions create store-policy risk. Buyers should test retained users, revenue cohorts, code ownership, data practices and dependence on one browser ecosystem.

How the business works

Browser-extension value depends on active users, retention, monetization, store-policy compliance, permissions/privacy, code/IP, organic discovery and developer dependence.

Risks to test

Browser-store policy changes
Sensitive permissions/privacy exposure
Key-developer dependence
Code/IP gaps
Low active use relative to installs
One browser ecosystem concentration
Security vulnerabilities

Evidence to request and reconcile

Store analytics
User/revenue cohorts
Code/IP repositories
Permission/privacy documentation
Security history
Support logs
Release history
Developer contracts

Decision questions

How many installs are truly active?
What retention exists after 30/90/180 days?
What permissions could trigger policy risk?
Who owns all code?
What security incidents exist?
Can another developer maintain releases?
How concentrated is revenue by browser?
What acquisition exists outside the store?
