Ask HN: Does your choice of technology affect your valuation?

Let's say we have two hypothetical startups that go through the startup gauntlet and are about to raise another round of funding. They are in the same industry and sell the same exact product with equal success. One startup built their stack on well known open source tech. Job postings for these technologies abound. The other uses lesser known tech and programming languages.

So, basically, all else equal (ceteris parabus), should these two companies be viewed differently by investors because of their tech stack?
