Spar

What it does

Running a business alone means every decision lives in your head. No one to push back, spot contradictions, or remember what you said 6 months ago. Spar is your AI co-founder — a thinking partner with memory that compounds over time. ✓ Learns your business through conversation ✓ Remembers everything across sessions ✓ Catches when new plans conflict with your goals ✓ Challenges assumptions instead of validating them $99/mo. 60-day free trial. No credit card required.

AI-powered silent co-founder for solo business owners. Persistent memory, challenges your thinking, detects contradictions. 14-day free trial, then $29.99/month.

Spar is your AI co-founder. It knows your business deeply, challenges your assumptions, remembers what you told it 6 months ago, and never just agrees with you. When there's work to do, it acts — researching competitors, drafting emails, prepping meetings, planning trips. Not another chatbot. A co-founder that knows your business, holds you accountable, and gets sharper every session. Remembers your revenue, team, fears, and goals across every session. Never explain your business twice. Pushes back on weak reasoning. Asks hard questions. The opposite of an AI that just agrees. Flags when your actions conflict with your stated priorities. Keeps you honest with yourself.

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
