How is Co-Founder different from GitHub Copilot or Cursor?

Copilots help you write code faster but you still have to drive. Co-Founder works autonomously — you set a mission, walk away, and come back to shipped code, strategic decisions, and progress reports.

What can an AI co-founder actually build?

Full-stack applications, APIs, landing pages, payment systems, blog posts, CI/CD pipelines — anything a technical co-founder would build. The agentfounder.ai website was built entirely by Co-Founder across 24+ autonomous sessions.

How much does Co-Founder cost?

Free 7-day trial (no credit card), then $499/month or $3,999/year (save 33%). Lifetime access is $1,999 one-time for the first 200 seats.

Do I need to be technical to use Co-Founder?

You need to describe what you want to build and review the output. You bring the vision and product sense, Co-Founder brings the execution.

Use Case

AI Co-Founder for Side Projects

You have a day job, a life, and maybe 2 hours a night to work on your thing. At that pace, your side project will take years to launch. Unless someone else is building it while you're at work.

The problem

Two hours a night isn't enough

By the time you context-switch from your day job, remember where you left off, and start coding, it's already bedtime. Progress is glacial.

Weekends disappear

You planned to build all Saturday. Then errands, family, and life happened. Sunday you got 3 hours. That feature still isn't done.

Motivation fades

Week 1 is exciting. Week 8 is grinding. Week 16 you're questioning everything. The slower you build, the more likely you are to quit.

You can't quit your job yet

You need revenue to go full-time, but you need full-time to get revenue. The chicken-and-egg problem of every side project founder.

How an AI co-founder helps

Builds while you work your day job

Drop a task in the INBOX before your morning commute. Your co-founder builds it during the day. Review it after dinner.

Turns 2 hours into 24

You spend 2 hours directing strategy. Your co-founder spends 22 hours executing. Same time investment, 12x the output.

Maintains momentum

No more cold starts. Your co-founder keeps the project warm every day, even when you can't touch it. Momentum compounds.

Gets you to revenue faster

The faster you ship, the faster you validate. The faster you validate, the faster you earn. Break the chicken-and-egg cycle.

A day in the life

7:30 AM—Before work: drop a feature request in the INBOX

9:00 AM - 5:00 PM—Your day job (co-founder is building in the background)

6:00 PM—Check status: feature is deployed to staging

8:00 PM—30 min review: approve, adjust, queue next task

10:00 PM—Co-Founder starts the next feature while you sleep

Weekend—You focus on marketing and customer feedback

“My side project launched in 3 weeks instead of 3 months. I never wrote a line of code during work hours -- my AI co-founder did it all.”

-- What we're building toward

The bottom line

Side projects fail because of time, not ideas. An AI co-founder gives you the time you don't have by building autonomously around your schedule.
