Frequently Asked Questions
Everything about entity registration and trademark clearing.
Why should I check domain, social, and LLC availability together?
Founding a company under a name where the .com domain is held by a squatter, the Instagram handle is taken by a competitor, or the name is already trademarked causes costly rebranding down the line. Brand Vault checks all three layers simultaneously.
Which state is best for registering an LLC?
Delaware is preferred by venture-backed startups due to its Chancery Court. Wyoming and New Mexico offer maximum privacy and low fees. However, if you are a local brick-and-mortar or sole proprietor operating in your home state, forming in your home state (e.g. California, Texas, Florida) often avoids foreign qualification fees.
How accurate is the live domain check?
Our checker queries Cloudflare authoritative DNS-over-HTTPS resolvers in real-time. If an A record, AAAA record, or nameserver is present, the domain is confirmed registered. Status 3 (NXDOMAIN) indicates immediate availability.
