I was chatting with a founder the other day about their growth plan, what size they could realistically reach and whether their approach was VC-compatible. So I thought long about it, and If you simplify things to the extreme, there are only a few proven ways to get there.

Rare, but possible in B2G or big Enterprise deals. Think SpaceX, Palantir, or Exotec : high-stakes, so more willing to pay a high-ticket. It’s definitely no easy task, and you need to be solving a mission-critical problem.
One of the models we see the most in BtoEnterprise (CRMs, HR software…) The challenge is getting those clients that are willing to pay a good $1M/ year and you need to find 100 of them. So either you go multi-industry and can get those 100 in a single market or you target a single-industry but getting there usually means going global. A lot of companies get stuck there invoicing “only” $100k with big logos (see next).
A real grind. Finding 1,000 clients willing to pay $100K isn’t impossible, but it’s tough. For that kind of price tag sales cycles can still be long therefore acquisition costs high, and scaling beyond your home market is a must but a challenge. This is where many European startups hit a wall. They reach 150-300 clients and struggle to push beyond that. Breaking through often demands multi-country expansion, smart positioning, and persistence.
This one's in B2SmallB territory with SMB-focused tools (CRM SMB, HR Payroll SMB) with contracts around $1K/month. Not easy but largely achievable if you have depth in your market. Hello Coverflex ;)
Really hard to pull off in B2C, as 100$/month is high given the mass market average salary. Here you’re better off targeting solopreneurs or niche pros. Possible, but no piece of cake.
Classic BtoC subscription model — think Spotify, Deezer, Netflix or Moneybox. Needs a strong value prop, flawless execution, and often cross-border scaling. .
The $1/month model, aka the social networks and casual gaming sauce! It's a different know-how and in Europe it usually requires multi geo by design so good luck …
So as a founder, here are the key questions worth asking yourself:
Now of course, there are as many ways to grow a company as the number of companies themselves as they are all unique. This simple framework is only meant to help founders ask themselves the right questions. Hope it helps !
