The full name is B.R.A.I.N.E.R., short for Businesses Run by AI, No Employees Required. Its philosophy page argues that the world doesn't need more disconnected agents and that AI should take ownership of the company and its outcome: you supply the idea, and it decides what must happen and does it. It also invites you to bring several ideas at once.
Nautis takes a much less dramatic position. It assumes a person is running a startup, often with a team and investors, and gives them a shared workspace plus an AI Chief of Staff that prepares the day and asks before it acts. Those are different bets about where AI is useful right now, and a founder could reasonably agree with either. We've only read published pages, so nothing here reports how well either performs.
The org chart B.R.A.I.N.E.R. gives you
You get an AI CEO reporting to you, and six departments below it. The homepage lays out each one, and this is where the product is most specific.
- CEO: plans the company, sets priorities, keeps the task board, checks in every 3 hours, sends a daily briefing and asks before anything sensitive.
- Strategy: market research, competitors, customer profile, positioning, pricing, idea validation and the launch plan.
- Product: defines the concept, decides what to build next, reads customer emails and tracks analytics.
- Engineering: builds the product and website, adds forms, sets up Stripe payments and tests each launch.
- Marketing: blog posts, SEO pages, social posts and directory listings.
- Sales: researches prospects, finds email addresses, sends cold emails and follows up automatically.
- Advertising: writes and designs ads, proposes targeting and budget, launches Meta ads and reports on them.
A sample on the homepage shows the idea in motion: a sales agent hears that small fleets feel overserved, the CEO proposes a smaller plan, engineering ships it and marketing writes about it. The company labels this a sample. That loop is something Nautis doesn't attempt.
Nautis vs BRAINER side by side
| Job | B.R.A.I.N.E.R. | Nautis |
|---|---|---|
| Starting point | An idea you describe | An existing or forming startup, with a website, deck or short description for setup |
| Build the product and website | AI product builder and website creation | Not covered in the guides |
| Cold email | Finds addresses, sends campaigns, follows up | Leads CRM tracks deals. Outreach sequences aren't covered in the guides |
| Paid ads | Meta ads launched and tuned, on Growth | Not covered in the guides |
| Blogs, SEO, social | Writes and publishes, with auto-posting on Growth | Social Calendar stops at approval, and publishing stays with you |
| Fundraising and cap table | Not listed | Find Investors, fundraising CRM, deck analyzer, data rooms. Cap table above the Launch plan |
| Finance records | Stripe integration and analytics. Other finance tools not listed | Startup Health, Financial Planner, Invoices, Expenses |
| Team and HR | "No employees required" | Up to 25 members, roles, employee management, team chat, recruitment |
| Daily briefing | From the AI CEO | From the Chief of Staff, at 7:00 am |
| Control of actions | You choose what runs automatically and what waits, action by action | Ask every time by default, per capability, with an audit log |
Notice the last row. Both let you set boundaries, and both keep a record. The difference is emphasis: B.R.A.I.N.E.R. sells autonomy with limits, while Nautis sells assistance that can be given more autonomy.
Two plans, and what each includes
Its homepage compares itself against a $1,250+ stack of separate tools and shows $79 a month. The pricing page adds a cheaper Starter. Nautis's plans start $10 above Starter and stop $50 above Growth, but buy a different set of things.
| Feature | Starter, $39 a month | Growth, $79 a month |
|---|---|---|
| AI credits | 1,500 | 3,000 |
| Product builder, website, blogs, SEO | Yes | Yes |
| Email finder, cold email, follow-ups | Yes | Yes |
| Inbound email, analytics, Stripe | Yes | Yes |
| Social auto-publishing | No, creation only | Yes |
| Meta ads | No | Yes |
| Custom domain and branded email | No | Yes |
| Code export and GitHub connection | No | Yes |
| Directories and full-funnel tracking | No | Yes |
If you care about keeping your code, note that export and the GitHub connection are listed only on Growth. Ad spend is also separate, charged by Meta to your own payment method, and B.R.A.I.N.E.R.'s terms say it takes no share. Fees already paid aren't refunded, and you can cancel at any time and keep access until the paid period ends. Nautis has a no-card trial lasting 14 days, and no $0 tier. We didn't see a trial stated on the B.R.A.I.N.E.R. pricing page.
What the terms leave with you
Anyone considering an autonomous service should read this part, and B.R.A.I.N.E.R. is clear about it. Its terms, last updated 16 September 2026, say that actions you've permitted to run automatically count as authorised by you, whether or not you reviewed them. You remain responsible for messages sent, content published, prices set and money spent. Compliance is also yours, and they don't guarantee that an ad will be approved or produce results. Disputes fall under Indian law, in the courts of Bengaluru.
That's a normal allocation of risk, and plainly stated. It has a practical meaning, though: cold email and paid ads have legal and reputational rules that vary by country, and an agent sending from your domain sends in your name. Start narrow, keep approvals on for anything outbound, and widen as you see the work. Nautis puts the same responsibility on you in a different way, since an AI Chief of Staff can't do everything, and any approved email is still yours.
Start from nothing, or start from something
Say you have an idea for permit reminders aimed at small landscaping firms. You have no code, no team, and an evening a week. Paying $79 to see whether an AI can stand up a site, test positioning and try some outbound is a cheap experiment, and Nautis has very little to offer you at that point. Your Nautis workspace would be empty and its briefing with it.
Now say you are a three-person seed startup with eleven customers and a Series A conversation starting in spring. An AI that changes your pricing page and emails prospects needs tighter limits, since existing customers and investors notice, and B.R.A.I.N.E.R. lets you set those action by action. What you likely need is everyone working from the same numbers, a pipeline of investors, and early warning on runway. That leans toward Nautis, and you could still point a separate experiment at a new market elsewhere.
The price of picking Nautis here
- Building. The guides don't describe generating a product or website. You need developers or another tool.
- Outbound doing itself. Nautis can draft and track. On the pages we read, B.R.A.I.N.E.R. goes further and sends, follows up and runs ads.
- Hands-off time. The default approval model means someone reviews. A founder wanting to step away will find that tiring.
- A lower entry price. $39 against $49, and $49 buys you planning and drafts, not marketing execution.
Nautis is also a young product. Its public launch came in July 2026 and independent coverage is thin, so don't weigh it as an established safe choice.
So which do you open?
- B.R.A.I.N.E.R. if you are starting something new, want it attempted without hiring, and are comfortable supervising an AI that acts publicly in your name.
- Nautis if customers, staff or investors already depend on you, and you want an AI business operating system that prepares decisions for people.
- Both, in separate lanes, if you run a real company and want to test a side idea. Keep the experiment on its own domain so that it can't touch the main brand.
FAQ
Who does the work in Nautis vs BRAINER?
B.R.A.I.N.E.R. aims to build and run a business from your idea using an AI CEO and departments. Nautis gives a founder and team a workspace for fundraising, finance, sales and tasks, and its AI Chief of Staff waits for approval by default. One replaces work, and the other organises it.
How much does B.R.A.I.N.E.R. cost?
In October 2026 it listed two plans: Starter, $39 monthly with 1,500 AI credits, and Growth, $79 monthly with 3,000. Growth adds Meta ads, social auto-publishing, a custom domain, branded email and code export. Ad spend is paid separately to Meta.
Can B.R.A.I.N.E.R. act without my approval?
It can if you allow it. Its pricing page says you choose what runs automatically and what waits for approval, action by action, and every action is recorded. Its terms treat permitted automatic actions as authorised by you.
Does Nautis build websites or run ads?
Its help guides don't cover either. You could publish a form or a jobs page from it, and its GTM Planner tracks experiments, but building a site and running paid campaigns need other tools.
