I've been trying to find tools that would show other domains that are owned or associated with the domain that was searched. I work with a lot of sales leads and I think having information on other domains a company owns is super powerful for mapping companies and also understand company acquisitions, most companies transfer ownership of domains when they are purchased.
I have a question and ask:
1. There are quite a few tools online that do the same thing, long term what is your goal to differentiate? or where do you want to focus?
2. Other TLDs or Other Associated Domains, is this something that you would be able to find?
3. Can you determine from a DNS search if a domain is owned by a company or by a non-corporate entity (Blog, personal)?
Also from your blog post, I don't know if you were looking for any responses but:
Plan B - Stage 2: Sell an API to visitors.
>I would purchase and use this for a email verification process. I would rather go with a smaller company than large
Plan C - Stage 1: Make a one-off DNS dataset, give it away to founders, and find out how they'd use it and what they need.
>I would use this with Email Domain verification and Email format Verification. I worked with data teams that had to find emails formats & domains, if they had the domains it would save a ton of time and cost. As an end user how I think about this cost is I if I find a domain and run a MX or DNS check on it I will save the results and try now to run it on that domain again. That is why I like this plan, but the API would be super helpful as well.
