Polsia alternatives: six AI tools that build or run a business, compared

Disclosure: Foundable publishes this comparison and is one of the six products in it. Every fact about another product is taken from that product's own website, reviewed on October 30, 2026, and linked where it appears. Prices and terms change, so confirm them before choosing.

In short: NanoCorp and Cofounder are the closest equivalents to Polsia; both use AI agents to run a company. Foundable suits owners who want Ted to run the business while they approve what goes out and receive payments in their own Stripe account. Durable fits local businesses that mainly need a website and customers, Lindy fits teams that want help with their own work, and Replit fits people building an app.

Why people look for a Polsia alternative

Polsia's terms (last updated September 17, 2026) set out several points worth reviewing:

• A 3% platform fee on customer payments, which are held in a Polsia balance for a 31-day settlement period before payout.
• A 20% fee on advertising spend, which runs through Polsia's own advertising account.
• Public company dashboards, on by default and open to indexing by search engines.
• Scheduled work that runs without approval for each action.

Polsia does not publish a pricing page. These terms suit some businesses and not others; they are the main points to compare.

The six compared

Foundable

Foundable publishes this comparison. Its AI employee, Ted, builds your website, sets up payments through a Stripe account in your name, writes your posts and emails and, through Run, works on the business in the background, with each action visible to you. By default, emails, posts and website changes wait for your approval; on paid plans you can switch Run to On its own. Foundable is free to start, and its plans are listed on the pricing page.

Best for: owners who want the whole business handled while keeping approval over what goes out, across shops, services, creators and local businesses as well as software.

NanoCorp

"Describe the business you wish existed. NanoCorp builds and runs it," says its homepage. It builds a landing page, app, database, payments and custom domain, and its agent "prospects, emails customers, runs Meta ads, and sends daily reports." Sales are held in the business's NanoCorp balance, and NanoCorp keeps a 20% fee on each withdrawal to your Stripe account (withdrawals). It is free to start with no card required; the Founder plan, from $30 a month, keeps a business running (pricing).

Best for: founders who want the closest equivalent to Polsia's fully automated model.

Cofounder

"Cofounder lets you run an entire company with AI," according to cofounder.co. It starts with an AI roadmap, then assigns engineering, sales, marketing, design, finance and operations to agents, which your own AI agent can direct. Agents request approval before potentially dangerous actions, and payments go through your own live Stripe account (payments). It costs $40 a month per company, including $40 of credits; an AI agent subscription is billed separately, and advertising costs the spend plus 10% (pricing). Cofounder is a different company from cofounder.ai.

Best for: founders who already work with an AI agent such as Claude or Codex.

Durable

Durable describes itself as "the complete AI business builder" (durable.com). It builds a website that can sell products "shipped, picked up, downloaded or booked," and its agents publish blog posts and collect reviews. Payments are processed by Stripe, and Durable states that it adds no fees beyond Stripe's (fees). A website preview is free; the Launch plan costs $25 a month, or $22 a month billed yearly (pricing).

Best for: local and service businesses that mainly need a website that brings in customers.

Lindy

Lindy describes itself as "the AI employee that plugs into your tools, learns how you work, and takes real work off your plate" (lindy.ai). It handles recurring work on a schedule across the tools a team already uses, and any action with outside impact, such as sending an email, waits for approval. It includes $50 of free credits for 7 days with no card required, then costs $29.99 per user per month (pricing).

Best for: established teams that want help with their own work.

Replit

"Turn ideas into apps in minutes — no coding needed," says replit.com. Its Agent writes, tests, fixes and publishes software, and apps can accept payments through your own Stripe account (payments). Projects published on the free Starter plan go offline after 30 days; the Core plan costs $20 a month, or $18 a month billed yearly (pricing). Replit builds the software; running the business afterwards remains with you.

Best for: building an app or tool yourself.

How these were chosen

These are the products most often named when search engines and AI assistants are asked for Polsia alternatives, limited to those that build or run part of a business. Tools that only write code for developers were excluded.

Questions

What is the best Polsia alternative?

It depends on what you want to hand over. For AI that runs an entire company the way Polsia does, NanoCorp or Cofounder. For Ted running your business while you approve what goes out and receive payments in your own Stripe account, Foundable. For a local business's website and customers, Durable.

Is there a free Polsia alternative?

Foundable, NanoCorp, Durable and Lindy can all be started without payment, and Replit offers a free Starter plan. Lindy's free credits last 7 days, and NanoCorp requires its paid plan to keep a business running.

Which alternative keeps customer payments in my own Stripe account?

Foundable, Cofounder and Replit take payments through a Stripe account in your name, and Durable pays into your connected account with no fees added to Stripe's. On Polsia, sales go to your Polsia balance less a 3% fee; on NanoCorp, they go to the business's balance, less 20% on withdrawal.
