What Spar does

Not another chatbot. A co-founder that knows your business, holds you accountable, and gets sharper every session.

Persistent Memory

Remembers your revenue, team, fears, and goals across every session. Never explain your business twice.

Challenges You

Pushes back on weak reasoning. Asks hard questions. The opposite of an AI that just agrees.

Contradiction Detection

Flags when your actions conflict with your stated priorities. Keeps you honest with yourself.

Tone Calibration

Five co-founder styles from Tough Love to Visionary. Adjust how hard Spar pushes you.

Document Analysis

Upload PDFs and images. Spar extracts the content and reasons over it as business context.

Searchable History

Semantic and keyword search across every session, fact, and decision. Nothing gets lost.

Proactive Check-ins

Follows up on your goals and open decisions via email. Your co-founder reaches out first.

Goal & Decision Tracking

Automatically extracts commitments from conversations and tracks them over time.
