No. 1Full AI cofounder, from $25/mo
Solo founders who want one AI cofounder for the whole business, not a stack of tools
Idea8.5
Build9.0
Sell9.6
Run9.6
The only tool we reviewed that fills all four founder seats on its own and keeps working after launch. It researches the idea, builds the site and app, sells through checkout, email, social, ads and phone, and runs standing tasks on a schedule or when something happens, like a new order or a failed payment. Payments land in your own Stripe account, and anything risky can wait for your approval.
Why it earns a seat
- Covers idea, build, sell and run in one agent, so nothing falls between tools
- Standing tasks run on a schedule or a trigger, like a new order, an inbound email or a missed call
- Payments settle into your own Stripe account; Crevio is not the merchant of record
- Every feature on every paid plan: custom domains, team, API, MCP, ads, phone
Where it falls short
- Credit-based billing: a busy month uses more credits, so the bill isn't a flat number
- 2.5% fee on your sales on paid plans, 5% on the free plan, on top of card processing
- The free plan is 100 credits given once, not a monthly allowance
- A newer company with a much smaller review footprint than Lovable, Replit or LivePlan

Founders who want an AI to build and run a simple online business on autopilot

Run8.5
A serious full-cofounder product with fast growth and a good approval model. It ranks below Crevio on coverage (no phone or company formation that we could confirm) and on trust: there are no refunds, and assisted export only opens after three paid months.
Why it earns a seat
- Builds, launches and operates, not just builds
- Propose mode for one-tap approvals, Autopilot for hands-off
- Sets up Stripe payments and runs Meta ad campaigns
- Plans by number of businesses, up to 10
Where it falls short
- No refunds
- Assisted export only after 3 paid months
- Custom domain starts on the $79 plan
- No phone answering or company formation that we could confirm

Small teams on Slack who want an AI teammate across their existing tools
Idea6.0
Build6.0
Sell6.5
Run8.0
Excellent as an AI operator for a team that already runs on Slack and has its tools in place. As a cofounder for a new business it's less complete: it works through your existing stack rather than providing the site, checkout and storefront itself.
Why it earns a seat
- Works where your team already talks
- Huge integration catalog
- Credits shared across the workspace, no per-seat price
- Generous no-card free credits
Where it falls short
- Needs an existing stack: no built-in site, checkout or store
- Usage pricing gets expensive for busy teams
- No annual discount outside Enterprise
No. 4AI founding team, from $20/mo
Product-minded founders who want research, build and launch marketing in one place
Idea7.5
Build8.5
Sell6.0
Run4.5
The best AI founding team for getting a product built and in front of searchers. It researches and builds well and even runs Google Ads, but it doesn't run the business after launch: no customer support or scheduled work.
Why it earns a seat
- A full agent team, from research to engineering to ads
- Sign-in, database, hosting and Stripe built in
- Code export and GitHub sync
- Generous free tier
Where it falls short
- Stops at launch: no support, follow-ups or scheduled operations
- Credits go fast on bigger builds
- The operating company isn't named on the site
- Custom domains not mentioned
No. 5AI employee, from $16/mo
Founders who want to automate specific recurring jobs with custom agents
Idea6.5
Build6.0
Sell5.0
Run7.0
Flexible and affordable for automating specific jobs, with a real free tier. As a cofounder it needs direction: you decide what agents to build, and it doesn't provide a storefront or payments.
Why it earns a seat
- Builds agents from a plain-language description
- Scheduled runs on every plan
- Free tier with daily credits
- Team members share the owner's plan
Where it falls short
- You design the agents; it doesn't drive the business
- No checkout or payments
- Only one scheduled run at a time on the free plan

Founders who want deep research and quick prototypes from one agent
Idea7.5
Build7.5
Sell5.0
Run5.0
One of the strongest research-and-build agents available, and great for testing an idea quickly. It's a general agent rather than a business operator: no checkout, ads or customer support of its own.
Why it earns a seat
- Excellent deep research and analysis
- Builds hosted sites and apps with sign-in, Stripe payments and your own domain
- Full code export
- Daily free credits
Where it falls short
- Builds and stops: no ongoing marketing, outreach or support
- Monthly credits don't roll over
- Among the worst Trustpilot reviews here, mostly over billing and support

Idea5.0
Build9.0
Sell4.5
Run4.0
The most capable builder for apps that need real backend work, with room to grow into a developer's tool. Like the other technical cofounders, it doesn't sell or run the business.
Why it earns a seat
- Handles complex, full-stack apps
- Database rollback and real deployment
- A full code editor when you need it
- Established company with a long track record
Where it falls short
- Effort-based pricing can be hard to predict
- More technical than Lovable or Base44

Why it earns a seat

- Code mode and export for when you hire a developer

- Backed by Wix
Where it falls short
