Web design, development and SEO for Big Sky businesses.
Modern Mustard Seed designs, builds and manages websites, SEO and AI search visibility, AI receptionists and custom software for Big Sky businesses. Big Sky lives between a ski season, a summer season and two quiet shoulders, with many owners and guests out of state, so we build sites that change with the season and a voice agent that answers every guest and homeowner call, whatever time zone it comes from.
Want to hear an AI receptionist first? Mr. Mustard, our own voice agent, answers (406) 312-1223 at any hour.

Two counties, one district
Big Sky's resort tax was first administered by the Madison and Gallatin county commissioners; the Big Sky Resort Area District now runs it for the unincorporated community.

In 2024 the district commissioned a study of governance options for Big Sky, including whether to incorporate as a municipal government.

Big Sky is about 50 miles south of Bozeman and 51 miles north of West Yellowstone and Yellowstone's west entrance.

Big Sky is unincorporated, and neither county appears on the state's list of certified local programs, so building code jurisdiction there rests with the State Building Codes Bureau.

The Montana Department of Revenue names Big Sky among the state's resort tax communities, which levy their own local resort tax and decide how it is spent. A shop, restaurant or lodge there collects a tax most Montana towns do not have.

Big Sky calls come from guests and homeowners who are not here yet. A family in Texas is booking a ski week, a homeowner in California is calling about a furnace alarm, and a contractor is fifty miles down the canyon at a supply house in Bozeman. Seasonal staff turn over every spring and fall, so the person who knew how to answer is often gone, and the caller with money to spend moves on to the next listing.
Gallatin Valley and the Yellowstone gateway
Big Sky is the unincorporated resort community in the Madison Range, split between Gallatin and Madison counties and governed for its resort tax by the Big Sky Resort Area District.
Big Sky is a resort economy built around the mountain, the meadow and the canyon: Big Sky Resort and the private clubs on the mountain, shops, restaurants and lodging in Town Center and Meadow Village, and a large layer of property managers, builders, caretakers and trades who look after homes owned by people who live elsewhere most of the year.
Winter is the main event, from the resort's opening late in the fall into April. Spring and fall shoulder seasons empty the place: the lifts stop, and many restaurants and shops cut hours or close for a few weeks. Summer brings golf, hiking, mountain biking and Yellowstone traffic on Highway 191.
We also serve Gallatin Gateway, Moonlight Basin, Gallatin Canyon, Bozeman.

What We Do Here
Web design, development and SEO in Big Sky, MT.
Web design and development in Big Sky
A Big Sky site is usually read by someone booking from far away, so it has to carry seasonal hours, availability and policies clearly and take a booking or enquiry without a call. We design it from scratch to feel like the place and make switching between seasons a five-minute job.
How we build websitesSEO and AI search visibility for Big Sky businesses
Big Sky visitors plan weeks ahead and increasingly ask ChatGPT or Google AI where to eat, ski, rent or who to call about a house. A complete Google Business Profile with honest seasonal hours, consistent listings and pages that answer specific Big Sky questions decide who those answers name. We set that up and keep it current through every shoulder season.

Straight Answers
What Big Sky owners ask us first.
Big Sky is not a city. Who governs it, and does my business collect resort tax?+
Big Sky is unincorporated and straddles Gallatin and Madison counties, so county government covers zoning and most services. The Big Sky Resort Area District administers the local resort tax, which voters first approved in 1992, and it is charged on taxable sales inside the district's boundaries. If you sell to visitors in Big Sky, ask the district about collecting it before you open.
SourceWhat happens to Big Sky businesses in shoulder season?+
Visit Big Sky says that during the spring shoulder season the resort's winter operations are complete, and many local restaurants and shops shorten hours or close for a period to renovate and rest staff. That is exactly when guests still call and find nobody, so a voice agent and a site with accurate hours keep the calendar and the reviews intact.
SourceDo you work with businesses in Big Sky?+
Yes. Modern Mustard Seed is based in Kalispell, about six and a half hours by road from Big Sky, so the work runs by phone, video call and screen share. The website, the voice agent and the software all live online, so the distance changes nothing about what you get. We also work with businesses in Gallatin Gateway, Moonlight Basin, Gallatin Canyon. Call us at (406) 250-6076, Monday to Saturday, 9 to 5 Mountain, or hear Mr. Mustard, our own AI receptionist, answer (406) 312-1223 at any hour.
Who is the best web design agency in Big Sky?+
We will not hand ourselves that title. What we can say plainly: Modern Mustard Seed designs and builds websites for Big Sky businesses from our studio in Kalispell, every site is designed from scratch rather than filled into a template, and you own the code, the domain and every account. Our guide to website options for a Montana business compares us with the alternatives, including doing it yourself.
Is there an SEO company that serves Big Sky?+
Yes, we do. Big Sky visitors plan weeks ahead and increasingly ask ChatGPT or Google AI where to eat, ski, rent or who to call about a house. A complete Google Business Profile with honest seasonal hours, consistent listings and pages that answer specific Big Sky questions decide who those answers name. We set that up and keep it current through every shoulder season.
How much does a website cost in Big Sky?+
Your website is scoped and quoted in the conversation as a set package. We agree the deliverables, price and timeline in writing before work starts, and changes to what we built are included.
What happens to calls that come in after hours in Big Sky?+
That is the gap a voice agent closes. Winter is the main event, from the resort's opening late in the fall into April. Spring and fall shoulder seasons empty the place: the lifts stop, and many restaurants and shops cut hours or close for a few weeks. Summer brings golf, hiking, mountain biking and Yellowstone traffic on Highway 191. A voice agent we build answers as your business at any hour, books the appointment, takes the message, flags the emergency and texts you a summary when the call ends.
