The problem with contracts and why founders lose.

Contracts are written by lawyers for lawyers. Founders sign agreements they do not fully understand, often under time pressure, without access to counsel. Lexicon is built to close this gap.

0%
of startup founders sign contracts they do not fully understand

A 2024 survey of early-stage founders found that two-thirds had signed agreements without understanding key terms like indemnification, governing law, or limitation of liability.

$0K
average cost of a contract dispute for a startup

Legal disputes arising from poorly understood contracts cost early-stage companies an average of $24,000 in legal fees before reaching resolution - often more than the contract's total value.

0 days
average time to get a legal review from a law firm

Traditional legal review takes 3 to 7 business days at $300 to $800 per hour. Most founders cannot wait and cannot afford it, especially for routine vendor or employment agreements.

What Lexicon detects

CRITICAL

Backwards indemnification

Clauses that require you to indemnify the vendor for their own product failures, security breaches, or IP infringement. This is one of the most common and dangerous MSA traps for startups.

CRITICAL

AI training on your data

Data use clauses that grant the vendor a perpetual, irrevocable license to train AI models on your business data. Often buried in Section 4 of SaaS agreements.

WARN

One-sided termination rights

Vendor can terminate in 7 days; you cannot terminate at all without cause. Combined with auto-renewal, this creates significant lock-in and negotiation leverage for the vendor.

WARN

Dangerously low liability caps

Liability capped at 1 month of fees. On a $5,000/month contract, the vendor can destroy your data and owe you only $5,000 regardless of actual damage.

WARN

Extreme non-compete clauses

Worldwide, multi-year non-competes in employment agreements. Unenforceable in California, heavily restricted elsewhere, but still capable of creating expensive litigation.

INFO

Missing security and data protections

No SOC2 requirement, no breach notification timeline, no encryption standards, no list of approved subprocessors. These omissions create risk even if no clause is explicitly bad.

OUTPUT FORMAT

Every analysis includes five structured layers.

01
Risk Verdict
02
Warnings (severity-rated)
03
Plain-English Summary
04
Negotiation Edits
05
Precautionary Actions
MODEL INTEGRATION

Demo mode and live mode - built for every context.

In Demo mode, Lexicon uses three hand-crafted scenarios with pre-analyzed outputs covering low, medium, and high risk contracts. No API key, no setup - perfect for live demos and pitches.

In Live mode, users supply their own API key. The contract text is sent to the model with a structured system prompt that enforces our five-layer output format. The model's response is normalized and validated before display.

SYSTEM PROMPT EXCERPT
