What makes it difficult for startups with an outdated tech stack to secure funding?

As a CTO, I can say that finding funding for a startup that is based on an old tech stack can be quite challenging. Investors are always looking for companies that offer something new, unique, and innovative. If your startup is built on outdated technology, it may be difficult to convince investors that your company can provide a competitive advantage in the market.

Using an old tech stack may also limit your company's potential for growth and scalability, as it may not be able to keep up with the rapid pace of technological advancement. This could be a major turn-off for investors who are looking for companies that have the potential to scale quickly and stay ahead of the competition.

In the words of Jason Calacanis, a successful entrepreneur and angel investor, "If you're using an old tech stack, you're starting with a disadvantage. You have to work twice as hard to catch up to where the market is going."

To overcome this challenge, it may be necessary to consider updating your tech stack or finding innovative ways to leverage your existing technology to create a unique value proposition. By doing so, you can demonstrate to investors that your company has the potential to be a game-changer in the industry.
