Paid Or Free Domain For Corporate Website?

I had a meeting with a university that wanted to know more about my startup, and they asked for a corporate website which I didn't have because I'm still seed stage and pre-revenue. I did consider setting up a corporate website before, but was too lazy since they're usually either blogs or e-commerce platforms. But now I guess I'm incenitivized to have one for legitimacy and to redirect third parties, so I don't need to keep explaining what my startup does or at least will intend to do.

I do recall having a WordPress account and a personal blog, and I think out of laziness and convenience I can just go for that or maybe consider Shopify. For WordPress, I can start out with a free domain and then later upgrade to paid and let them host it. I ain't gonna code a corporate website from scratch because it's less labour intensive to build a blog with no-code solutions, whereas for e-commerce too complex to build myself when Shopify is a thing. I just don't wanna keep on paying a monthly nor yearly fee just to keep the rights to the domain right now.
