People usually leave Atoms for one of the reasons in its review: 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. Its weakest score on our rubric is Run, so we've ranked the alternatives below with that in mind. Read the full Atoms 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
Idea8.0

Sell7.5
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
No. 3Full AI cofounder, from $49/mo
Founders who want an AI to build and run a simple online business on autopilot
Idea7.5

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
Idea7.5
Build7.5

Run8.5
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
First-time founders who want a strategic partner to talk things through with
Idea8.0
Build7.0
Sell6.5
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
No. 6Full AI cofounder, from $20.83/mo
Cautious founders who want every outreach email and ad approved before it goes out

Run7.0
A cheap, approval-first AI cofounder with payments in your own Stripe account. It's lighter than the leaders on support, social and day-to-day running, and its revenue share kicks in once you pass $1,000 a month.
Why it earns a seat
- Low price: $25 a month or $250 a year
- Payments go to your own Stripe account
- Approval before anything customer-facing
- Built-in CRM for leads and customers
Where it falls short
- Revenue share above $1,000 a month, plus 1% per charge
- No social posting, support or company formation mentioned
- Prices have changed: older pages list $50 a month
- The company behind it isn't named on the site
No. 7AI employee, from $50/mo
Small teams on Slack who want an AI teammate across their existing tools
Idea6.0

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. 8Full AI cofounder, from $30/mo
Heavy Claude or ChatGPT users who want a side business run from their chat
Idea6.5
Build6.5
Sell6.5
Run7.5
A clever way to run a company from the AI chat you already use, with real scheduled work. The 20% fee on withdrawals makes it costly once revenue arrives, and it does less on the website and support side than the leaders.
Why it earns a seat
- Runs from Claude, ChatGPT or any MCP client
- Scheduled agent work with budget caps per task
- Unlimited businesses and custom domains
- Credits roll over
Where it falls short
- 20% fee when you withdraw revenue
- Revenue sits with the platform until you withdraw it
- No refunds, and higher credit tiers have no published price
