The Opportunity

Problem

Indie hackers face prohibitively high costs and excessive complexity when hiring lawyers for basic contracts and NDAs needed to protect their small businesses.

Solution

HackVault lets indie hackers upload, sign, and manage all business contracts in one dashboard. AI scans docs for expiration dates and sends renewal reminders. Track signatures, versions, and counterparties effortlessly.

Target Audience

Indie hackers and bootstrapped small business owners building SaaS or digital products solo or in tiny teams

Differentiator

Contract lifecycle management optimized for tiny teams—reminders prevent IP leaks from forgotten NDAs.
