Marblism sells a team of named agents on one plan: Eva for the inbox, Sonny for social media, Stan for leads, Penny for SEO, Rachel for the phone, Walter for websites and Linda for legal documents. Its pricing page reports 40,000 businesses and a 4.8 out of 5 Trustpilot score, and describes customers from solopreneurs and coaches to agencies and startups. The company's llms.txt describes the audience more narrowly, as contractors, tradespeople and service businesses.
The easiest mistake here is treating these as two versions of one thing because both use AI agents. Marblism's agents go out and do visible work in the world. The Nautis agents mostly read your company's records and propose the next action. A founder could reasonably want one, the other or both, and the deciding factor is where the company is stuck this quarter.
Is your problem getting noticed, or staying on top of things?
If nobody knows you exist, if calls go unanswered, or if your blog last moved in spring, Marblism aims straight at that. Sign up, describe your business and goals, and it says the employees handle tasks and check in only when they need input.
If people do know you, and the trouble is a missed investor follow-up, a stale burn number or an unsigned contract, that's closer to what Nautis was made for. The Nautis Social Calendar won't post your Reels, and Nautis has no AI phone line. Its Social Calendar guide says plainly that it's for planning and approving content, and that you still publish from your own tool or by hand for now.
The seven employees, and where Nautis stands on each
| Marblism employee | What Marblism says it does | Closest thing in Nautis |
|---|---|---|
| Eva, executive assistant | Drafts email replies in your voice, takes meeting notes, chases follow-ups, manages the calendar, sends a morning briefing | MailBox with AI summaries and smart replies, scheduling, and the Chief of Staff briefing. Transcripts come through a connected tool such as Fathom |
| Sonny, social media | Watches trends, creates photos and videos, posts 3 times a day on 7 platforms | Social Calendar for planning and approvals, with no connected publishing |
| Stan, lead generation | Searches 700M+ verified contacts, runs LinkedIn and email outreach, books meetings | Leads CRM with pipelines and stages. Prospect database and outreach sequences aren't covered in the guides |
| Penny, SEO | Weekly articles, keyword finding, rank tracking, site audits, internal links | Not covered in the guides |
| Rachel, receptionist | Answers calls 24/7 in 100+ languages, books appointments, texts you a summary | Not covered in the guides |
| Walter, website builder | Builds a site from a prompt, keeps improving it, connects a domain | Not covered in the guides. Custom Forms publish as public pages |
| Linda, legal assistant | Drafts contracts, flags risky clauses, explains legal language | Keel, an AI advisor for startup legal, and DocSign for signatures. Neither replaces a lawyer |
That's a one-sided table, and it's meant to be, because it uses Marblism's own list. Now reverse it. On the pages we read, Marblism doesn't list an investor CRM, cap table, data rooms, runway tracking, customer invoicing, task boards or employee records. Those are the bulk of the Nautis product.
The bill, as of October 2026
Marblism has one plan with every employee included: $24 a month billed yearly, or $44 billed monthly. It includes 50 hours of AI work a month, unlimited team members and unlimited businesses, with a 7-day money-back guarantee. Those hours reset monthly and are consumed only by advanced actions, since chat and quick tasks don't draw on them. You can buy top-ups.
| Team | Marblism | Nautis | Metered by |
|---|---|---|---|
| 1 to 5 people | $44, or $24 on yearly billing | Launch, $49 | 50 AI hours against 1,000 AI credits |
| 6 to 10 people | $44, or $24 on yearly billing | Voyage, $99 | 50 AI hours against 2,000 AI credits |
| 11 to 25 people | $44, or $24 on yearly billing | Fleet, $129 | 50 AI hours against 2,600 AI credits |
| 26 or more | $44, or $24 on yearly billing | Above the 25-member cap | Same 50 AI hours, shared |
On price alone Marblism wins at every size. Keep the meter in view, though. Fifty hours across seven employees and a whole team may stretch thinly if everyone uses them, and we can't tell you how far an hour goes, since the pages don't say what each action costs. Nautis credits have the same uncertainty for a large team: split across 25 people, Fleet leaves roughly 104 credits a head.
Two morning briefings, built from different material
Both products promise something waiting for you each morning, so this is where they most resemble each other. Marblism lists a morning briefing every day as part of Eva, alongside inbox and calendar work.
The Nautis briefing appears at 7:00 am local to the organization and scans the whole workspace: tasks, pipeline, runway from Startup Health, meetings, approvals, overdue invoices, burnout check-ins, fundraising signals and decision reviews. It's per organization, so it describes the company's day and not one person's. You can act on items with Do it, ask Commodore, or snooze them. If your working life is your inbox and calendar, Eva's source material may well be enough. Nautis pays off if the facts you keep missing sit outside email.
How much do you want done without asking?
This is a real difference in temperament. Marblism's language favours autonomy: set the goal, they own it, and they work on their own, checking in if they need approval. Stan runs LinkedIn outreach on autopilot and Sonny publishes for you. Its comparison table on the pricing page separately grades jobs done alone against jobs you approve each time.
Nautis defaults the other way. Capabilities start on Ask every time, cards wait in the Approval Center, and an owner or admin may change that setting per capability. Deleting always asks. That costs attention, and someone has to clear the queue. Choose by which failure would hurt you more: a post or cold email going out unreviewed, or a useful action sitting there until you get to it.
A Tuesday at a six-person seed startup
Say you sell booking software to dental clinics, have six people, and closed a small seed round a few months ago. Here is what each product could reasonably cover in a day, based on what they publish.
- Marblism's share: Penny drafts this week's article on missed appointments. Sonny turns it into posts. Stan finds clinic managers and follows up. Rachel picks up the 9:40 pm call from a clinic owner on the west coast and books a demo.
- Nautis's share: The 7:00 am briefing flags a clinic invoice that is 20 days overdue and a demo follow-up that slipped, and shows runway alongside them. The founder updates two investors in the fundraising CRM, then sends a contract through DocSign. A new deal from that demo goes on the Leads CRM board.
- The gap between them: leads Stan finds don't reach the Nautis pipeline by themselves. Nautis connects to 1,000+ apps through a managed catalog, but we couldn't confirm a Marblism connection on the pages we read, so you would be moving those by hand or through another tool.
At six people, $24 to $44 on top of a $99 plan is a small bet if marketing is starved. If it isn't starved, skip it.
Reasons to pick Marblism
- You sell to local or service customers and missed calls are lost jobs. A 24/7 receptionist has no counterpart in Nautis.
- You have no marketing person and want content, social and outreach running this month.
- You run more than one business. Unlimited businesses under one account is unusual, and Nautis connections and briefings are per organization.
- Your team is over 25. No seat cap appears on its pricing page, and Marblism for Teams offers one Eva per team member.
- You want scale and history. Its reported user base is far larger than anything Nautis can claim, given that it only launched publicly this July.
Reasons to pick Nautis, and what they cost you
Nautis makes sense between pre-seed and Series A when the things you drop are operational, particularly during a raise. Investor lists, deck review, data rooms and runway sit together, with the same AI reading all of it. The startup operating system guide shows how those pieces connect.
You pay more for it, and you do more of the outward work yourself or with other tools. Nothing in Nautis will grow your audience for you. It also takes moving your company's records in, and its usefulness rises only as you do. If that sounds like too much for your current problem, listen to that instinct.
FAQ
Who does what in Nautis vs Marblism?
Marblism provides AI employees that do outward-facing work such as posting, prospecting, SEO and answering calls. Nautis stores a startup's records, and its AI Chief of Staff briefs you and asks before acting. They overlap mainly on email and the morning briefing.
How much does Marblism cost?
As of October 2026, $24 a month billed yearly or $44 billed monthly. That covers all seven AI employees, 50 hours of AI work a month, unlimited team members and unlimited businesses. It offers a 7-day money-back guarantee and paid top-ups.
Does Nautis post to social media or answer calls like Marblism?
No. In Nautis, posts get planned and signed off in the Social Calendar, then go out from your own tool or by hand for now. Its guides don't cover an AI phone receptionist. Marblism lists both as core jobs.
Can Marblism replace a lawyer, or can Nautis?
Neither should. Marblism's Linda drafts and reviews contracts, and Nautis has an AI legal advisor called Keel, but AI output can be wrong. Use them to prepare, then have a lawyer check anything that matters.
