Should I officially change my company name with Delaware?

First time founder. Won some school grant to form legal entities, and use for other operations expenses, but it's limited. I ended up forming a Delaware C Corp as I heard most of people who try to raise VC money do that.

The question is we pivoted our product to a totally different area, so we also decided to change name of the company as well. I'm looking into the process and cost to change name with Delaware, seems very complicated and costly -- hundreds of dollars. (We feel other areas need this money more than changing names.)

We're trying to raise a round of VC money next month. If it goes ok, I assume we will receive check to our company. Should I spend money to it now or it's totally fine to officially change the name after we have enough money?

Thanks for all you guys help!
