The short answer: both run your company with AI, but kitty.build proves every action with evidence, waits for your approval on anything outbound, and leaves you owning the repo, the domain and 100% of the revenue — while Polsia runs on its own infrastructure and reviewers report a 20% share of revenue and managed ad spend. Polsia is faster and more hands-off; kitty.build is checkable. Credit where due: Polsia proved founders want an AI that runs the company.
| Area | Kitty | Polsia |
|---|---|---|
| Validates the idea before spending your money | 9 specialist AI boards research the market live and deliver a cited GO / PIVOT / NO-GO verdict first. | Launches anything instantly — reviewers report no demand-validation step. |
| Task honesty | A task is only "done" with verifiable evidence — a URL, row ids, a deploy id. Empty evidence ⇒ not done, by schema. | Independent reviews found tasks marked complete that never deployed (one audit: 41/47 "complete", ~21% real). |
| Human control over outbound | Publishing, ad spend and outreach always wait for your approval. Auto-mode is one deliberate, reversible toggle. | Sends cold email and posts autonomously by default; users report sends they never reviewed. |
| Who owns the company | Your GitHub repo, your Cloudflare, your domain, your Supabase, your Stripe. Export the full build package anytime. | Hosted on Polsia-controlled infrastructure; users report losing site and domain access when a subscription lapses. |
| Who keeps your revenue | 100% yours, settled in your own Stripe. We never touch the money. | A reported 20% of economic activity — revenue and managed ad spend — routed through Polsia first. |
| What failure costs you | Failed tasks are free. The evidence ledger makes billable-vs-not auditable. | Credits are consumed on failed and duplicate tasks; refund complaints are common in public reviews. |
| Builds and hosts your site | Yes — generated, revisioned, published to Cloudflare Pages on your own domain. | Yes — live in minutes on their subdomain. Genuinely fast. |
| Codes on your product | Feature requests become reviewed builds: AI edit → deploy → commit pushed to your repo. | On-demand code generation; exported code has been reviewed as skeletal. |
| Organic social | 8 platforms, angle rotation measured by real performance, multi-market native-language posts, comment→DM automation. | X auto-posting; more platforms announced. |
| Paid ads | Channels, spend sync, creative drafted from your proven organic angles, and guardrails that can pause spend — never raise it — on their own. | Meta and Google ads created and managed autonomously, budget included. |
| Runs while you sleep | Daily cycles plus bounded Night Shift sessions with visible time, cycle and dollar caps. | Fully autonomous nightly cycle — the founding idea, and it ships. |

If what you want is a machine that launches something and keeps moving with zero input from you, Polsia is the most aggressive product in this space and it is the only one here that manages paid ad campaigns end to end, budget included. kitty.build deliberately waits for your approval before anything goes out, which is slower. If approval gates feel like friction rather than safety, Polsia is built for you and we are not.
Polsia proved that founders want an AI that runs the company, and the overnight cycle genuinely ships. The problem reviewers keep hitting is that "done" is not checked: tasks close without evidence, outbound goes out unreviewed, and the company lives on Polsia's infrastructure with a reported 20% of revenue and ad spend flowing through them. kitty.build takes the same autonomy and adds two constraints Polsia does not have — a task is only done with a verifiable artefact attached, and nothing outbound sends without your yes — while your repo, domain and Stripe stay yours.
Nine boards, live research, every claim cited, GO / PIVOT / NO-GO — for $0. If it says NO-GO you just saved months and never paid us. If it says GO, Kitty starts building. Watch real ventures doing it on our live feed.
