This page is about Cofounder at cofounder.co, made by The General Intelligence Company of New York. It isn't about CoFounder.AI at cofounder.ai, a separate company with a separate product, which has its own comparison if that's the one you meant.
Its docs call the product CofounderOS, and they mark a real shift: people who used the earlier web app now have their own agent run their companies through MCP or a command line tool. So you aren't buying an assistant. You are buying the tools and services an assistant you already pay for can use.
Do you already work inside a coding agent?
This decides most of it. If you spend your day in Claude Code or Codex, Cofounder fits how you already work. You connect over MCP or its CLI, ask for a company, and your agent runs a managed setup that creates a repository, a hosted app, a database with sign-in, analytics, a company inbox, a Stripe test sandbox and a roadmap.
If that sentence means little to you, Nautis is the safer start. You give Liftoff a website or pitch deck, connect Google or Microsoft calendar and email, and about four minutes later you have a workspace that reads like a company rather than a terminal.
Cofounder does have a dashboard, where you can answer what your agent needs from you and read the company's mail, contacts, files and money. But its docs describe that as the place you check in, and the agent does the driving.
A meter or a plan limit: how the money works
Cofounder charges $40 per company per month as of October 2026, and all of that comes back as usage credit. Unused credit rolls over. Your Claude, Codex or other agent subscription is separate, and services draw from your balance at published rates. Nautis has three fixed plans, at $49, $99 and $129 monthly, and those include the AI up to a credit cap.
| Service | Rate |
|---|---|
| Agent email inbox | First free, then $2 a month each |
| Agent phone number | $3 a month each |
| Basic database | About $15.55 a month running all day |
| Google and Meta ads | Ad spend plus 10%, so $100 of ads uses $110 |
| Domain purchases | Cost price, no margin |
| Contact lookups | About $1.20 per 100 |
| Image generation | About $0.01 to $0.34 per image |
| LLC incorporation | Add-on, with statutory filing fees separate |
The calculator in its docs shows one example month: five extra inboxes at $10, one database at $15.55 and $4 of hosting. That uses $29.55 and leaves $10.45 to roll over. Add 1,000 contact lookups and $200 of ads and you're buying credits. It says most users stay inside the $40 while getting started and may need more once there are real users and traffic, and its docs pricing page says most businesses never need a top-up. Hosting keeps drawing credit even when your agent is idle.
So the honest total is $40, plus your agent subscription, plus metered use. For a single person that can still beat Nautis, and it comes with infrastructure Nautis doesn't offer. It is harder to forecast. In Nautis the bill is fixed and the limit is the cap: when credits are gone, sending halts until the reset or a top-up.
What each product can actually touch
| Area | Cofounder | Nautis |
|---|---|---|
| Building the product | Repository, deploys, database, secrets, payments through Stripe | None. Task boards track the work, and GitHub connects through the integration catalog |
| Getting customers | Prospecting, CRM, email campaigns, ads, SEO, social posting | Leads CRM, GTM planner, custom forms. Social Calendar plans posts but you publish them yourself |
| Customer support | Support inbox where each email becomes a ticket | Not a listed module |
| Forming the company | US entity formation through Ramp, inside the product | Not offered |
| Fundraising | Not in its docs list | Find Investors, fundraising CRM, investor readiness, deck analyzer, data rooms |
| Runway and finance | Wallet, Stripe billing, money view in the dashboard | Startup Health, financial planner, invoices, expenses |
| Team | Invite members to a company. Its People guide finds hiring candidates. HR not in its docs list | Employee management, recruitment, team chat, Burnout Radar |
| Daily review | Company brief and roadmap read on request, plus event notifications. Its homepage says agents can be customized with schedules | 7:00 am briefing generated without asking |
One founder's first six months
Take a solo developer with a half-built tool for dental clinics. In month one she needs it deployed, a domain, a Stripe checkout, a company inbox and a US entity. In month three she wants 200 clinic owners researched and emailed. In month six she has 40 paying customers and an angel asks for a data room.
Cofounder covers months one and three unusually well, because her agent can do the provisioning, the prospecting and the sending in one place. Nautis wouldn't help with deployment at all.
Month six is where Nautis starts to earn its place. The fundraising CRM holds the angel conversations, a data room logs who opened what, and the briefing shows the deal next to her runway. Nothing about Cofounder stops her from doing this elsewhere, but we didn't find these jobs in its docs.
If she has to pick one on day one, it should be Cofounder. She can add a fundraising workspace when the conversations begin.
How each one asks permission
Cofounder's homepage says agents need approval when potentially dangerous actions are taken, and that nothing ships without yours. Its docs say your agent buys, provisions and moves money only when you ask, with managed setup as the exception because it is free. Steps only you can do come back as a link. For paying other merchants, you approve each purchase separately.
Nautis routes things through one screen. Agent requests queue in the Approval Center, each with a plain summary and the exact text or change. Owners and admins approve, and capabilities default to Ask every time unless someone sets one to Run without asking. Deleting always asks.
A practical difference follows. With Cofounder, your own agent's behaviour and its host's permission settings are part of the picture, since that agent is doing the work. With Nautis, the rules live in Nautis, which is simpler for a non-technical co-founder to read and less flexible for a developer.
Leaving later: what the docs say
Cofounder publishes an unusually frank FAQ on ownership and continuity. Repository access lets you copy your code and Git history, and Library files can be downloaded. It also says a code download doesn't move a database, stored files, hosting accounts or domain registration, and that running independently takes the matching provider accounts and replacement credentials. Check that page before your product depends on managed infrastructure.
In Nautis your risk is different. It holds records rather than your product, and the cap table has a JSON export. Moving out means moving pipelines, documents and history, so plan a tool consolidation in reverse before you commit.
Where Nautis is the weaker choice
- It costs more for one person. Launch is $49 with no $0 option, against $40 that returns as credit, though Cofounder's agent subscription is extra.
- It can't build anything. No hosting, no database, no deploys.
- It sells less for you. Cofounder lists prospect search, email campaigns and ads run by your agent. Nautis tracks leads and plans campaigns, with a lot left to you.
- It's newer to the public. Cofounder's homepage reports over 10,650 companies running on it, and its resources page announces an $8.7 million seed round. Nautis launched on Product Hunt in July 2026.
- No named security attestations to cite. Cofounder's footer refers to one. Nautis doesn't claim any.
Choosing between them
- Cofounder if you are technical or comfortable directing an agent, the product isn't live yet, and you want one bill for infrastructure and go-to-market tools.
- Nautis if the product already exists elsewhere and your problem is running the company around it: investors, runway, invoices, hiring, a team of up to 25. The solo founder page shows what the smallest plan includes.
- Both can work, since each speaks MCP. Nautis has a connector for Claude and ChatGPT, so a Claude user could reach both from one chat. Decide which holds customer records, or you'll keep two CRMs.
FAQ
In one sentence, what separates Nautis vs Cofounder.co?
Cofounder gives an AI agent you already use the tools to run a company, through MCP, a CLI or an API. Nautis is a workspace people log into, with a built-in AI Chief of Staff and modules for fundraising, finance and team. One is for directing an agent and the other for running records.
How much does Cofounder cost?
As of October 2026 it costs $40 per company per month, including $40 of usage credits that roll over. Your AI agent subscription is separate, and services such as hosting, research and ads draw from your credits at published rates. You can add credits while subscribed.
Is cofounder.co the same as cofounder.ai?
No. Cofounder at cofounder.co comes from The General Intelligence Company of New York and connects to your own agent. CoFounder.AI at cofounder.ai is a separate company based in Marina Del Rey that gives you an AI cofounder with a specialist team.
Do I need to code to use Cofounder?
Its site doesn't say coding is required, but you do need an AI agent connected through MCP or the CLI, and its docs are written around that setup. They list Claude and ChatGPT as well as coding agents. A founder who has never used one may find Nautis quicker to start. Nautis setup takes about four minutes and needs a website, deck or short description, plus a connected calendar.
Can Cofounder help me raise money?
Fundraising tools didn't appear in the docs index we read in October 2026, though your agent could help with research and documents in general. For that job, Nautis publishes investor search, deal stages, a readiness score and data rooms.
