People usually leave Viktor for one of the reasons in its review: needs an existing stack: no built-in site, checkout or store; usage pricing gets expensive for busy teams; no annual discount outside Enterprise. Its weakest score on our rubric is Idea, so we've ranked the alternatives below with that in mind. Read the full Viktor 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

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

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

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 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
No. 6AI employee, from $24/mo
Existing small businesses that want marketing and admin help at a flat price

Very good value for an existing small business that wants help with marketing and the inbox. It isn't a cofounder in the build-the-business sense: it doesn't create your site, product or checkout.
Why it earns a seat
- One flat price for seven AI employees
- Unlimited businesses and team members
- Chat and quick tasks don't use the hour cap
- Phone reception included
Where it falls short
- Doesn't build your product, site or checkout
- 50-hour monthly cap, with paid top-ups
- No free plan

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
No. 8AI employee, from $15.60/mo
Owners who want help writing posts, emails and content
Idea5.5

Run5.5
Affordable on a yearly plan and easy to start with for content and marketing help. It doesn't build or run a business: no website, product or payments.
Why it earns a seat
- Twelve helpers in one plan
- Shared Brain AI keeps outputs on-brand
- Low price on the yearly plan
- Easy for owners who don't want to write prompts
Where it falls short
- No website, product or payments
- 250 monthly credits run out quickly
- Pricing leans on large "sale" discounts
- Trustpilot withholds its rating over review incentives
