In all honesty, don't. Seriously, this is bad advice. Nobody is going to visit your website and say "woah, this looks like Attio's website - I'm out!" with, evidently, the exception of a few folks from Attio. The website looks good, you and the other company aren't truly direct competitors so branding conflicts are not much of a concern, and if you both truly just derived your designs from a root common theme then I don't know why this is even being brought up here, unless the other commenters were unaware that their design was derived from a template. There are undoubtedly things significantly more worth spending time on as a very early startup then redesigning your website to appease a few people on HN, who were (assuming the common template bit is true) in the wrong for raising this issue to begin with and and should be updating their comment with this context.
EDIT - apologies, the OP here is not from Attio which was my assumption and would've made the OP's post unnecessary but an understandable reflex to seeing a doppelganger of their own website. If you check the OP's profile to see which company they're _actually_ from you will certainly realize that this entire comment chain should be fully ignored. It's pretty shitty, actually.
I think I was pretty open in my comment (cofounder).
They copied Attio's SVG image and everything. My issue was not the aesthetics but the fact they copied another organization's work. Surely, you don't think that's right?
Are you serious, man? You edited your comment, twice. We both know your comment did not include "(cofounder)", but did include unnecessary jabs at your your competitor ("this makes me lose all faith in our credibility.") when you posted it. I've used Budibase and think it's a great product, and couldn't have anything but respect for the people behind it. You're above this.
EDIT - Apologies, you did indeed include "(cofounder)" in your original post, I just missed it (based on bing's cached page.) Regardless, this is not the way to deal with competitors, and frankly your product speaks for itself. And perhaps obscene amounts of torrenting in my teenage years has permanently skewed my moral compass for these things, but I really don't care about table cell background svg theft.
