I would have to disagree with that definition. There are tons of companies that are scaling non-linearly without using any particularly new technologies.

I don't consider a frying pan manufacturer a tech company just because they have managed to grow by optimizing their supply chain and productivity.

Alternatively I also think a company that makes brand new technology year after year even if they scaling one for one with hiring is still a tech comapny

I think what you describe might just be a general guideline for identifying a financially successful company not necessarily a tech company. People hear VC funding or IPO and often automatically think it must be a tech company by conflating technology and financial success.
