People usually leave Bolt for one of the reasons in its review: token use grows quickly on larger projects; free sites carry Bolt branding; no marketing, sales or operations. Its weakest score on our rubric is Run, so we've ranked the alternatives below with that in mind. Read the full Bolt review.
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
No. 2Full AI cofounder, from $40/mo
Technical founders who already pay for an AI coding agent and want departments run around it

Run8.0
The closest rival to a full AI cofounder. The department model is well thought through and the per-company price is simple. The catch is that you also need your own AI coding agent subscription, such as Claude Code or Codex, and the $40 includes only $40 of usage.
Why it earns a seat
- Clear department structure with shared company context
- LLC incorporation with approval gates on risky actions
- Simple per-company price, with usage credits that roll over
- MCP, custom APIs and custom skills for extending it
Where it falls short
- Requires a separate AI coding agent subscription on top of the $40
- $40 of included usage can go quickly on an active company
- Older third-party pages quote different prices and a trial, so check before you buy
- Built for people comfortable directing coding agents

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
No. 4Full AI cofounder, from $20/mo
Experimenters who want to launch several small companies and let them run overnight

Polsia made the autonomous-company idea famous and does run tasks every night without prompting. It loses ground on cost and trust: its cut of payments and of ad budgets adds up fast once you have revenue, it doesn't do refunds, and reviewers often mention credits spent on fixes.
Why it earns a seat
- Genuinely autonomous: works on your company every night
- Cheap to start a single company
- Website, database and business email included
- Handles outreach and ads, not just the build
Where it falls short
- Takes a share of your payments and ad spend on top of the plan
- No refunds
- Reviewers report credits used up on corrections
- Pricing has changed several times, so older reviews quote other numbers
No. 5AI founding team, from $39/mo

Run7.0
A strong strategy partner with a friendly, conversational setup, including voice and phone access. It relies on integrations for payments and marketing rather than doing them itself, and it only opened in June 2026, so there's little track record yet.
Why it earns a seat
- One cofounder that keeps your priorities, with specialists behind it
- Voice mode, plus phone and text access
- Dev Shop builds pages and portals from plain language
- 60+ integrations, including Stripe, Gmail, LinkedIn and X
Where it falls short
- Launched June 2026: little independent track record
- Payments and marketing run through integrations, not built-in features
- Hosting and domains cost extra
- No ads management described

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
- Nothing for marketing, sales or operations

The best AI technical cofounder for non-coders: fast, polished and with a big community. It builds the product; finding customers, selling and running the business stay with you.
Why it earns a seat
- Polished apps from plain-language prompts
- Backend, hosting and sign-in built in
- Code mode and export for when you hire a developer
- Large community and templates
Where it falls short
- Credits go to fixes as well as features
- No marketing, sales or operations
- Busy apps can use credits for hosting

Run3.5
The easiest app builder for complete beginners, with friendly pricing. Payments come through services like Stripe that you connect yourself, and growth and operations are left to you.
Why it earns a seat
- Very beginner-friendly
- Sign-in, database and analytics included
- Custom domain and a free domain for a year on paid plans
- Backed by Wix
Where it falls short
- Two separate credit pools to keep an eye on
- No marketing, sales or operations
- Message credits limit how much you can iterate
