A traditional web agency vs an AI product studio
A traditional web agency builds a website and often keeps you on a monthly retainer to host, update and market it. An AI product studio like Modern Mustard Seed builds the website plus the systems around it, such as an AI receptionist that answers every call and agents that follow up on leads, and hands you full ownership so you can run it without the studio. Choose the agency when you want a large team, a long brand campaign, or someone permanently on call. Choose the studio when you want a site that works for the business, AI built in, and no dependency.
