The assumptions in your screen capture are dramatically more aggressive than any company in history. E.g. You are showing 60% yoy revenue growth 10 years in. For comparison: Google in year 10: 31%. Amazon in year 10: 23%. Dropbox in year 10: 27%.
If these kinds of growth rates were possible, there would likely be much higher discount rates to go with them.
Lots of investors do long term DCFs like this (and almost all update 5-year models on a rolling basis).They're just not as useful as a shorter term model given lack of visibility that far into the future and likelyhood of having to return funds well before then.
Yes, once you scale really big it is hard to keep a high growth rate. But if you have been always growing at 50% YoY, it is possible to keep that rate even at year 12. This is pretty common amount bootstrappers. I am speaking from my own experience at the company I founded: JotForm’s last 7 years were at 50%.
TWLO, SHOP, etc are all growing at >50% 10 years in. It's very likely and common, especially in b2b SaaS where it's challenging to capture all of a fragmented market and/or you have a case where you can continually upsell with more product over time.
