Most people starting a business assume the wrong things. They assume it will move faster than it does, cost less than it will, and work out because the idea feels good.
I have started seven businesses and sold one, FreeUp, for eight figures after four years. I put in $5,000 and grew it to $12 million a year, bootstrapped, with no US employees.
The assumptions I made early are a big reason it worked. Here are the ones I would hand any founder before they spend a dollar.
TL;DR: What must an entrepreneur assume when starting a business?
An entrepreneur must assume that risk is real, money runs out faster than planned, and the early sales land on their own shoulders. Assume the first idea will change, cash flow matters more than profit on paper, and systems are what let you step back later. Above all, assume nobody is coming to save the business but you.
The real odds: assume risk, but know the actual number
Every list tells you to assume failure. Fair enough. The figure they quote is usually wrong.
You will hear that 90% of businesses fail. Government data says something calmer. Roughly half of new US businesses are still operating at the five-year mark, according to the Bureau of Labor Statistics.
So assume the risk is real and survivable. About one in two make it past year five, and the ones that last tend to share dull habits like clean books and steady cash. I walk through the downside honestly in the risks of entrepreneurship.
The 7 assumptions I would make starting over
These are the working assumptions behind every business I have built or bought.
1. Assume it costs more and takes longer than your plan
When Connor and I built the first version of FreeUp, we spent $5,000 and it was the crummiest software you can imagine. The billing stayed manual far longer than I would like to admit. Every timeline I drew turned out to be optimistic.
Build a buffer into both money and time. If your spreadsheet says six months, plan for nine and keep enough cash to survive the gap.
2. Assume you will do everything yourself at first
In the early days you are the founder, the salesperson, the support team, and the bookkeeper. That part is normal. The trap is staying there.
Do each job long enough to understand it, then write down how it works so you can hand it off. The mindset shifts that made this click for me are in 15 game-changing principles of entrepreneurship.
3. Assume cash flow is what keeps you alive
Profit on a spreadsheet means nothing if you cannot make payroll. Cash is what kept us in the game. Here is how I have described the model we ran:
“A lot of companies are not cash flow positive. I work with e-commerce companies that are constantly buying inventory. With us, we would get paid by the client, take our percentage, pay the freelancer on delay, so we always had cash on hand.”
Collect from the client first and settle with the contractor on a lag. Every jump in volume then puts more money in the bank instead of pulling it out.
4. Assume you cannot scale without systems and a team
A company that only runs when you are in the chair is a job with extra stress. Assume from Day 1 that you want it to run without you, which means documented processes and people you trust. That single assumption changes how you hire and how you write things down.
We got FreeUp to $12 million a year with a team of about 30 virtual assistants in the Philippines and no US employees. The systems carried the work, so the business kept moving when I stepped back.
5. Assume the legal and financial setup matters from Day 1
The boring paperwork you skip now becomes the expensive problem later. Your business structure shapes your taxes, your filings, and your personal liability, as the Small Business Administration lays out. The IRS spells out how each entity gets taxed, so pick with both in mind.
Keep clean books from the very first transaction. When we sold FreeUp, spotless bookkeeping was what let the buyers see exactly what they were getting, and the deal closed because of it.
Treat this as my experience rather than legal or tax advice, and confirm your own setup with a professional before you file anything.
6. Assume your first idea will change
The plan you start with is a hypothesis. FreeUp began as a fix for our own hiring headaches on our Amazon business, then became a marketplace once we saw other founders had the same problem.
Hold the vision loosely and let real customer feedback redraw it. The founders who survive are the ones who listen and adjust when the market talks.
7. Assume the responsibility lands on you
No investor, co-founder, or hire will ever care about the business the way you do. That sounds harsh. Owning it fully is also the thing that lets you build something real.
Assume the weight sits on your shoulders and plan for it. Weigh that honestly against the upside first, which I lay out in the pros and cons of entrepreneurship.
What the assumption lists get wrong
Most articles on this keyword hand you the same generic checklist: assume risk, assume competition, assume you need a plan. All true. All close to useless without the part they skip.
Those lists rarely tell you what to assume about your own cash, your own time, and your own dependency on the business. The founders who make it assume the unglamorous truths early and build around them.
Frequently Asked Questions
The questions I get asked again and again about what to assume when starting a business are answered below.
Bottom line
Assume the honest version of the road: it costs more, takes longer, and rests on you. Assume that cash flow and systems matter more than the pitch. Do that, and you are planning with your eyes open instead of your fingers crossed.
The founders who last are the ones who assumed the boring truths early and built around them. That mindset is the throughline from my first dorm-room hustle to an eight-figure exit.
