DocuInsight

AI-powered contract intelligence platform that integrated with DocuSign to simplify legal agreements

Retired As Of May 2025

What Was DocuInsight?

We built an AI-powered platform to solve the "Agreement Trap" where people sign contracts without understanding their rights and obligations.

The Problem We Tried to Solve

In early 2024, co-founder Mehmet signed startup contracts without fully reviewing them. His business partner later used additional equity to force him out, and Mehmet discovered he had signed away important rights. This experience sparked the idea for DocuInsight.

🤖

AI Contract Analysis

Used OpenAI's advanced models to analyze legal documents, highlighting key clauses, risks, and commitments in plain English.

💬

Interactive Chat

Users could "talk" with their contracts, asking questions about specific clauses and getting real-time, web-researched answers.

⚖️

Legal Counsel Connection

Generated optimized search queries to connect users with relevant lawyers based on location and contract type.

📝

DocuSign Integration

Seamlessly integrated with DocuSign's signing workflow, displaying insights alongside the signature process.

📄

Multiple Document Formats

Supported a wide range of document formats including PDF, DOCX, DOC, and image files for comprehensive contract analysis.

Our Business Journey

From hackathon excitement to harsh market realities, here's how our business validation went.

December 2024

The Idea

Built for DocuSign Hackathon after researching contract complexity issues.

💡
February 2025

Customer Discovery

Talked with lawyers and SMB owners. Found polite interest but no urgency to pay.

👥
March 2025

VC Feedback

Got honest feedback: "This is a feature, not a company"

💼
May 2025

Shut Down

Realized the business model was flawed. Made the hard decision to shut down.

Why DocuInsight Failed

An honest post-mortem of what went wrong and why we decided to shut down.

The Hard Truth

DocuInsight wasn't killed because it was bad sense it actually worked well. We killed it because we realized it couldn't become a venture-scale business. Better to cut losses early and reallocate energy to higher-potential projects.

💰

What VCs Said

"Too narrow market, platform risk with DocuSign, no clear expansion path. This looks like a vitamin, not a painkiller."

🎯

Wrong Market Fit

We built analytics for a workflow step that wasn't a burning pain point. Lawyers wanted drafting tools, SMBs wanted pipeline visibility.

⚠️

Platform Risk

Built on DocuSign's APIs. If they changed terms or added similar features, our business could disappear overnight.

📈

No Customer Urgency

Nobody said "We need this tomorrow." Polite interest doesn't translate to paying customers.

What We Learned

Key takeaways from building, validating, and ultimately shutting down DocuInsight.

🎯

Customer Discovery First

Talk to customers before building. "Would this be nice to have?" is very different from "I need this tomorrow."

💡

Feature vs. Company

Ask "Why can't the platform owner build this themselves?" If you don't have a good answer, you're building a feature.

💰

Business Model First

Who pays? How much? Why? These questions need clear answers before you build.

Know When to Quit

Sometimes the smartest thing is to shut down early and move on. Sunk cost fallacy is real.
