This page is about CoFounder.im at cofounder.im. Similar names belong to other products, including the ones on our Cofounder.co and Cofounder.ai pages, and nothing here describes them.
CoFounder.im is really three products under one account. A set of 20+ agents analyzes your idea and prepares documents. Startup Mode adds team and equity management. A Chief Executive Agent, or CEA, runs a daily work cycle on a project. Nautis overlaps a little with each and more with none, so we take them in turn, using its homepage, pricing, CEA and Startup Mode pages as read in October 2026.
The agents: documents you can hand over
You describe your idea in up to 5,000 characters, and agents take on specific jobs: idea validation, problem validation, market research, competitor analysis, customer personas, business model, monetization, regulatory compliance, MVP planning, team architecture, funding advice, investor discovery, accelerator recommendations and more. The site groups them into bundles, from a 3-agent Market Validation set to a 26-agent Complete Package, and says an average analysis takes about 12 minutes.
Outputs include a pitch deck in PowerPoint, PDF and Markdown, and a consolidated report in Word and PDF. There's also a useful link to coding tools. It can produce an implementation plan for coding assistants, and your build specification is available as an MCP server that works with Claude Code, Cursor, Windsurf, Cline and GitHub Copilot.
Nautis has some parallel pieces. Business Plans drafts by section, SWOT builds a first draft from your profile and deck, and Find Investors offers a searchable directory with match scores. Nautis doesn't write your deck or generate a build spec according to its guides. If your next step is a report for a cofounder or a spec for a coding agent, CoFounder.im is more direct.
Startup Mode next to Nautis's cap table
Once the Team Architect agent has run, you can activate Startup Mode. It adds email invitations for co-founders, AI-suggested roles and equity splits, an option pool and a cap table covering founder shares, the pool and investor allocations, with vesting schedules and share types. You can export to PDF, Excel and other formats, and it's included with all subscriptions.
That's a helpful starting point for an early team, especially if splitting equity is the awkward conversation you're having now. Nautis goes further on the later events: its cap table records SAFEs, convertible notes, preferred stock and warrants, handles conversions, keeps a transaction history and models scenarios such as a $2M investment at a $10M pre-money. It's only on Voyage and Fleet, though, from $99 a month. Nautis's Equity Calculator, for the initial founder split, is on those plans too. Neither should replace a lawyer on the final documents.
The Chief Executive Agent: does it ask first?
The CEA is where the philosophies part. CoFounder.im describes it as an autonomous system that makes executive decisions. It evaluates your company's state, picks one high-impact task each day, runs it, reports back and starts the next cycle. Its table contrasts a copilot that suggests with a CEA that "decides and executes". You get a morning summary of what happened overnight.
Its tasks include social posts, landing pages hosted at your-project.cofounder.im, competitor research, Stripe Connect checkout, and provisioning GitHub repositories, databases and web servers. It follows a five-week playbook. You can chat to change direction, approve or skip steps, or pause it. The FAQ says every completed task is logged, nothing goes out that you cannot review, and you can set approval requirements for specific action types.
A Nautis morning runs in the other direction. The 7:00 am briefing shows what needs attention, you choose Do it, and a card waits for review unless an admin has opened that capability. In short, CoFounder.im defaults to working while you sleep and telling you later, with controls you can tighten. Nautis defaults to asking, with controls you can loosen. For a company with investors, customers and a reputation to protect, we prefer the second default. Someone who wants progress with minimal input may reasonably prefer the first.
One point in CoFounder.im's favour is its candour. It labels some specialists as still planning: the distribution, nurture and close roles "plan the machine now, with live execution rolling out", and it states that the sales team never contacts anyone on your behalf. More on that in our guide to human-in-the-loop agents.
What a hired CEA costs per month
Pricing has two layers, and adding them gives you the real figure. A tier buys monthly credits to run all agents. Hiring a CEA adds a per-project subscription on top, and the CEA draws credits from your tier as it runs. When credits run out, it pauses until you top up or upgrade. All figures were current in October 2026.
| Plan | Tier price | Credits or limit | With one CEA |
|---|---|---|---|
| CoFounder.im Idea | $9.99 | 1,000 credits, up to 10 project ideas, 1 CEA | $58.99 |
| CoFounder.im Launch | $29.99 | 3,500 credits, up to 25 project ideas, 3 CEAs | $73.99 |
| CoFounder.im Scale | $99 | 13,000 credits, unlimited project ideas, 8 CEAs | $139 |
| Nautis Launch | $49 | 5 team members, 1,000 AI credits | Chief of Staff included |
| Nautis Voyage | $99 | 10 team members, 2,000 AI credits | Chief of Staff included |
| Nautis Fleet | $129 | 25 team members, 2,600 AI credits | Chief of Staff included |
Without a subscription you get 100 welcome credits and can create up to 3 projects, so looking around costs nothing. The CEA has a 3-day trial, and Nautis's trial runs 14 days with no card. The CEA page's search description mentions $79 a month, while its body and the pricing page show the per-project figures above, which are the ones we've used. Purchased credits don't expire, and the credit units aren't comparable between the two products.
Nautis vs CoFounder.im across a startup's needs

| Finding investors | Investor Discovery report | Searchable directory, added straight into a pipeline |
| Tracking a raise | Not listed | Rounds, deals, stages, Raise HQ |

| Marketing execution | CEA posts and hosts pages, with more roles rolling out | Social Calendar plans posts, and you publish |
| Team operations | Invitations and roles in Startup Mode | Directory, pay runs, Team Chat, Burnout Radar |
| Work with coding tools | MCP server for build specs | MCP connector for Claude and ChatGPT into your workspace data |
A realistic fork in the road
Say you and a friend have spent three months on a logistics idea with no product. You want to know if it's worth quitting your jobs, then split equity fairly. CoFounder.im matches this closely: a validation bundle, a competitor report, the Team Architect's suggested split and a spec you can feed to a coding tool. Nautis would be overkill and would cost more for less of what you need.
Now say it's a year later. You have 8 staff, a seed round in progress and 20 customers. An agent posting and provisioning on its own schedule matters less than knowing what your next investor conversation needs. Here you'd want the fundraising CRM, a data room and a shared task list, and Nautis is the more natural home.
Being fair to both
- CoFounder.im is ahead on idea analysis, generated documents, coding-tool handoff, price of entry at $9.99, and an agent that takes initiative.
- Nautis is ahead on the records of a running company, default approvals and support for a team of up to 25.
- Nautis is weak on generating things. It won't write your deck or ship your landing page, and its Social Calendar won't post for you. It's also young, public since July 2026, with little independent coverage so far.
- A data point to weigh: CoFounder.im says your data stays private to your account, and that the platform learns anonymized performance signals across its network. Nautis's Learning Engine learns only from your own organization's data. Read both policies if this matters to you.

FAQ
Is CoFounder.im the same as Cofounder.co or Cofounder.ai?
No. This page covers cofounder.im only. The other names are separate products, and we have separate comparison pages for Cofounder.co and Cofounder.ai.
What is the difference in Nautis vs CoFounder.im?
CoFounder.im focuses on analyzing ideas, generating documents and running an autonomous agent on a project. Nautis focuses on the records and daily operations of a working startup, with changes approved by default. Earlier-stage founders will usually find CoFounder.im closer to their needs.
How much does CoFounder.im cost?
As of October 2026 tiers are $9.99, $29.99 and $99 a month. Hiring a CEA adds $49, $44 or $40 a month per project depending on tier. Credits can be topped up, and purchased credits don't expire.
Does the Chief Executive Agent need approval to act?
Its page describes it as deciding and executing by itself on a daily cycle, with a morning report. You can pause it, redirect it and approve or skip playbook steps. The FAQ says nothing goes out that you cannot review, and that you can set approval requirements for specific action types. As with any agent, check those settings before connecting your own accounts.
