A second-time founder knows that vesting comes before the first big argument, that a data room gets built before anyone asks, and that a monthly number matters even when it's small. You don't know these things yet. Nobody does, the first time. The worst gaps aren't the things you know you can't do. They're the deadlines you've never heard of.
Experienced founders can skip most of what's below. For you, the order matters more than the tool, so this page is laid out in the order you'll need it.
Four mistakes software won't catch unless you look
Some first-time errors are costly and cheap to avoid. Check these this week, whichever tools you use.
| Mistake | Why it hurts | Where a tool helps | Who to ask |
|---|---|---|---|
| No written founder agreement | Equity fights are hard to settle after the work is done | Equity calculator (Voyage and Fleet) for a reasoned split | A startup lawyer |
| Missing the 83(b) deadline in the US | The IRS instructions require filing within 30 days of the transfer | A task with a due date. That's all software does here | A lawyer or tax adviser |
| Signing a SAFE without doing the math | Ownership sold is the investment divided by the post-money cap | Cap table scenarios (Voyage and Fleet), or our cap table simulator | Your lawyer, before you sign |
| Not knowing how long the money lasts | You find out too late to raise or cut | Startup Health check-in, or our runway calculator | You, every month |
A note on the 83(b) row. It applies to US taxpayers receiving restricted stock, and the form goes to the IRS by mail. If you're outside the US, ask what your own version of this is. Don't take a marketing page's word for tax matters, including this one.
What does a first-time founder do first?
Talk to customers first, then set up only what your next step needs. Here's a sensible order for your first month, assuming you've got an idea, maybe a co-founder, and no paying customers.
- Day 1: run Liftoff. Give Liftoff your website or deck. If you don't have either, click I don't have either yet and describe the idea. It takes about four minutes and shows the source of each detail it found.
- Day 2: open the Startup Journey. The Journey Tracker is a guided timeline of stages, milestones and tasks from idea to scale. This is the module that matters most for you, and others barely need it. Mark tasks that don't apply as Not applicable and you won't be penalised.
- Week 1: settle the split. If you have a co-founder, have the conversation now. CRV suggests four-year vesting with a one-year cliff and getting it in writing. See our founders' agreement guide.
- Week 2: write down what you believe. Log your first calls in the Decision Loop: who you're selling to, what you'll charge, what would prove you wrong. Choose a 30, 60 or 90-day review.
- Week 3: talk to 10 potential customers. Use the Contacts module or a notebook. Our customer interview guide helps with what to ask.
- Week 4: pick one number. Sign-ups, calls booked, or revenue. Put it on a Task Board as a KPI task, and read it every Monday.
Paul Graham's list of mistakes that kill startups includes launching too slowly, having no specific user in mind, and founder fights. Notice that tools fix none of these directly. Being organised around the wrong idea is still failing.
Learning the language without feeling stupid
Investors and lawyers use words you've never needed. You'll hear pro rata, liquidation preference, post-money and cliff in one meeting, and most people won't stop to explain them.
Three places in Nautis help with this, and they serve different moments.
Glossary, for a quick lookup
The Glossary defines startup terms with examples and links to related terms. It's read-only and costs no effort. Keep the tab open during your first investor call.
AI advisors, for your actual situation
The AI Advisory Board has specialists such as Anchor for finance and Keel for startup legal. Attach a document and ask what a clause means in plain words. Then ask what you should raise with your lawyer. Use it to prepare for a professional conversation, not to skip one. It can be wrong, and it's not legal or financial advice.
AI Voice Coach, for practice
If you've never pitched, the AI Voice Coach lets you try it on an AI venture capitalist before a real one hears you. Full Pitch runs about 20 minutes and is marked beginner friendly. Leave Mock IC and Term Sheet Negotiation for later. Sessions use AI credits.
Which plan to start with, and when to change it
Your trial starts on Launch, which is 14 days with no card. After that Launch costs $49 a month, or $490 a year as of October 2026. It includes 5 team members, 1,000 AI credits and 5 Chief of Staff routines, and that's enough for your first few months.
Asking lots of beginner questions uses credits quickly. Each advisor message spends some, and a consultation between advisors costs extra. If you watch the balance in the AI Usage tab, you'll learn fast which questions are worth asking the board and which the Glossary already answers.
Move to Voyage at $99 a month for one of two reasons: you need the Equity calculator to work out a co-founder split, or the Cap table because someone has given you money. You don't need Fleet yet. If your first year needs more than 10 people on the workspace, that's a good problem to come back to.
What software can't teach you
Taste in customers, how to fire someone, when to quit an idea, and whether a person can be trusted all come from doing the work and from people who've done it. Find a mentor or a small founder group early. Nautis has an events directory in the app, which is only a starting point.
Nautis also doesn't teach a management method. There's no EOS or OKR framework built in. If you want a structured way of running the company, EOS for startups explains one option, and you'd need to run it by hand or use a tool made for it.
When Nautis isn't the right call
- You haven't talked to a customer yet. Spend the $49 on coffee with potential buyers. Come back when there's something to organise.
- You'd use it to feel busy. A complete Startup Journey is not traction. If you're ticking boxes instead of selling, close the tab.
- Your budget is close to zero. Paying for a workspace with no revenue is a real cost. A spreadsheet, a shared drive and a good lawyer will get you through the first months.
- You want proof from other founders. Nautis launched publicly in July 2026, and independent reviews are few. Run the trial on real work instead, and judge it on that.
FAQ
What software for first-time founders is actually worth paying for?
At the very start, very little: email, a calendar, a spreadsheet and a place to keep documents. Add e-signature and something to track customers when you have them. An all-in-one such as Nautis makes sense once several of those are in use and you want one view across them.
Is Nautis good for someone who has never run a company?
It suits that reader in specific ways, such as the Startup Journey timeline, the Glossary and AI advisors that explain terms in plain words. It won't teach judgment, and it's breadth over depth. You still need a lawyer, an accountant and experienced people to talk to.
Can an AI advisor replace my startup lawyer?
No. An advisor can explain a clause and help you prepare questions, which can make legal time cheaper. Founder agreements, equity documents and financing papers should still be reviewed by a qualified lawyer in your country.
Is there a way to try it before paying?
Yes. There's a 14-day trial with no card, starting on the Launch plan. After that you need a paid plan, from $49 a month as of October 2026, because Nautis has no permanent unpaid option.
