Web design for Kalispell and Whitefish businesses.
Modern Mustard Seed is a web design and development studio in the Flathead Valley, Montana. We design and build websites for businesses in Kalispell, Whitefish, Columbia Falls, Bigfork and Polson, then manage them for you after launch: hosting, updates and changes are included. Every site is designed from scratch around your real work and built so Google and AI search can find and cite you. You own the code, the domain and every account.

Every form and chat lands where you act on it: a text and an email the minute it comes in, one record per person.

Built to be read
A page for each service and each town, clean markup and structured data, so Google, Bing and AI assistants can read who you are and what you do.

Built Right in Montana
A custom home builder in Northwest Montana since 1997. We rebuilt the site at 36 pages around their real projects and their reviews word for word, added a chat that answers the way their office does, sent every lead to the office by text and email the minute it lands, and moved both domains home. Live since September 25, 2026.

What Kalispell and Whitefish owners ask first.
Who is the best web design company in Kalispell, Montana?
We will not hand ourselves that title: judge the work. What we can say plainly is that Modern Mustard Seed designs and builds websites for Kalispell businesses from our studio in the Flathead Valley, designs every site from scratch, manages it after launch with changes included, and hands you ownership of the code, the domain and every account. Open the Built Right in Montana site we built for a Flathead Valley custom home builder, then call us at (406) 312-1223.
Who is the best website designer in Whitefish, Montana?
Again, judge the work, ours included. Here is how we design for Whitefish: Whitefish customers often decide from another time zone, before they have ever walked down Central Avenue. The website is the first impression and often the only one before money changes hands, so we design for that buyer: fast on a phone, clear about availability and the season, and built to take the booking or the enquiry without a phone call.
Do you build websites for Columbia Falls, Bigfork and Polson businesses too?
Yes. We work across the Flathead Valley and the rest of Montana, and with clients nationwide. Each town has its own page on our site with what we know about how business works there.
How much does a website cost in Kalispell?
Your website is quoted as a set package in the conversation, with the scope, price and timeline agreed in writing before work starts. We never bill by the hour, and changes to what we built are included. We do not publish prices on the site.
Will my website show up in ChatGPT and Google AI answers?
We build it so AI search can find and cite you: answer-first pages, a page per service and per town, structured data, a consistent name, address and phone everywhere, and a Google Business Profile that matches the site. No one can promise that an assistant will name a business, and we do not.
Who owns the website when it is done?
You do. The code, the domain, the hosting account and every login are in your name. We run it for you, and you can take it in house any time.
Can the website answer the phone too?
Yes. The Talking Website pairs the site with a voice agent that answers your calls from the same set of business facts. A contractor driving between jobs on Highway 93 is exactly who it is for.
