This directory lists companies that sell websites, hosting, and AI services to businesses in Napa Valley. Every entry was compiled from the provider's own website on October 28, 2026. Entries are factual summaries in our own words: what the company sells, what it publishes as pricing, and where it says it is based. Listings are in alphabetical order, are not rankings or endorsements, and no provider paid to be included.
How to choose
Decide whether you want a product or a project. A bundled managed plan trades control for simplicity: one monthly bill, a template-driven site, and little to maintain. A custom studio or agency costs more, quotes per project, and builds around your business. Neither is automatically better; the right answer depends on whether your website is a brochure or a sales channel.
Keep ownership of the assets. Whoever you hire, the domain name, the website content, and your customer data should be registered and exportable in your business's name. Ask, before signing, what leaving looks like.
Ask what the AI feature actually does. In current Napa offerings, "AI" can mean a builder that drafts a site from a description, a chatbot that answers customers on your site, or an audit of how your business appears inside AI search answers. These are different products at different prices. Ask to see the feature working on a live customer's site, not a demo.
Wine businesses should ask about wine fluency. Wineries sell under age gates, shipping restrictions, and club allocations, and most run on platforms such as Commerce7 or WineDirect. A wine-specialist provider usually costs more and asks fewer basic questions. A generalist can be the right buy for a business whose online needs are ordinary.
