Big text, clear buttons and your phone number one tap away. Most people will find you on a phone, so that is where we start.

    A free conversation about your business and what the site has to do. You get the price in writing before any work starts.

  2. Step 2

    Build

    You get a working preview link early and tell us what to change. Nothing goes live until you approve it.

  3. Step 3

    Launch and look after it

    We host it, keep it updated and make your edits. When you need a change, you text the person who built it.

23D tours for realtors and home builders

Walk through a home that is not built yet.

We build an interactive 3D model from a floor plan and photos. Nobody has to visit, so it works for a listing next week or a home that only exists on paper.

Sample 3D model: a single-story home with a two-car garage, seen from the street in daylight. Sample 3D model from the air at golden hour, with low warm sunlight across the front of the home. Sample 3D model at twilight with the lights on inside and on the porch. Sample 3D model with the roof lifted off, showing every room and its furniture from above. Sample floor plan from above, with each room labeled with its name and size. Sample walk-through view from the great room toward the kitchen and dining area. Open the 3D model

3D model — illustrative. Finishes, furniture and landscaping may differ. Sample home drawn for this site.

Spin it, zoom in and change the time of day yourself.

3Software & automations

If your team does it by hand every day, we can probably build it.

Software shaped around how your business already works, connected to the tools you already pay for.

  • Client and customer portals
  • Intake and quote forms
  • Dashboards for your numbers
  • Automations between your apps
  • Scheduling and job tracking
  • Internal tools for your team
Fixed written quote

You see the price before we start, and it does not move unless you change the scope. Optional monthly support, quoted with the project.

Describe your project

A customer fills out a form

Job details and photos, typed once.

The work routes itself

Into your calendar, your books and the right person.

You see it all in one place

A dashboard and a text when it matters.

Example automation: a customer form goes into your systems and shows up on one dashboard. The numbers are an illustration, not a client result.

  • A review request goes out automatically after each job
  • Seasonal reminders to past customers who opted in, like a spring gutter checkBusiness Site
  • A fresh Google listing post every monthBusiness Site

Advice first, then the build

Say the right thing before you spend a dollar.

Before anything is built, we work out a clear message, a real offer and a plan for where to spend. The approach comes from LaRoy Kingsley, our Senior Advisor, who ran a Bismarck advertising agency for 34 years.

Google, Facebook, radio, a mailer or a yard sign: whatever fits your customers. Then we build the site and the follow-up to match.

  • What to say and who to say it to
  • An offer people act on
  • Where to spend, and where not to
  • A website and follow-up built to match

524/7 cybersecurity monitoring

Someone watching the doors, all night.

Your logins to Microsoft 365, Google Workspace, AWS and Cloudflare are doors nobody is watching at eleven on a Sunday night. We watch them and text you in plain English when something looks wrong.

  • 36 detection engines across four cloud services
  • Alerts by text, email, Slack or Teams, with steps to fix it
  • Setup in under 10 minutes. Nothing to install on your computers.

Plain answers to fair questions.

Websites and payment

Half of the build price when you say yes, and the other half at launch. Your monthly care plan starts at launch, not before. Nothing is billed beyond your plan without your approval in writing. Your domain is registered in your name. Invoices come from Stripe, and you can pay by bank transfer (ACH) or card.
Your domain, content, photos and logo are always yours. If you ever leave, we hand over your domain and a full copy of your site files. For custom software, who owns the code is written into your quote before work starts.
Hosting, the security certificate, updates, backups, the marketing listed on your plan, and the monthly edit time on your plan. Edit time does not roll over. Bigger changes, like more pages or new features, get a fixed written quote first. The care plan does not include 24/7 cybersecurity monitoring, which is a separate plan.
Yes. The Front Desk Assistant is a chat assistant on your site that answers customer questions 24/7 from your own information (hours, services, staff, aftercare), collects the details of a consult or quote request, and emails you a brief. It never quotes a price, never takes a payment, and sends anything urgent or medical to your phone. Every conversation is logged for you. It is an add-on to any website plan, quoted with your site.
Yes. The Follow-up Plan is a one-time setup and a flat monthly fee, quoted in writing. It covers Google listing cleanup, automatic review requests, reminder texts and emails to customers who opted in, and a photo-quote form you can link from any website.
Only customers who checked a box saying they want texts, on your quote form, invoice or job paperwork. Everyone can reply STOP, and texts never go out late at night. Customers who did not opt in get email instead, with a link to opt in if they want texts. Your business has to be registered with the phone carriers before texts start, which takes a couple of weeks. Email review requests start at launch.
Yes. Client portals, intake forms, quoting tools, internal dashboards and automations between the apps you already use. Tell us what your team does by hand today, and we will tell you plainly whether software can fix it and what it would cost. Every project gets a fixed written quote before work starts.

3D tours

No. It is built from the floor plan and photos, not scanned with a camera. The layout and size follow the plan, and the agent or builder confirms the dimensions before it goes live. Finishes, furniture and landscaping are illustrative, so every model and every still image carries the label “3D model — illustrative. Finishes, furniture and landscaping may differ.”
A floor plan with dimensions and the listing photos. If the home is not built yet, the plan belongs to its builder, so we need the builder’s written OK first. Builders send their own plans and option lists.

24/7 cybersecurity monitoring

If your IT provider is doing 24/7 cybersecurity monitoring across Microsoft 365, Google Workspace, AWS and Cloudflare with documented response steps, you do not need us. If they are not, or if you are not sure, we layer in alongside them. We share alerts with your IT contact directly and we make their job easier, not harder.
Under ten minutes for a single integration. Microsoft 365 and Google Workspace are an OAuth approval. AWS is a CloudFormation template you paste a Role ARN from. Cloudflare is an API token. No agent on any computer. No appliance to ship.
You pay monthly for the plan you pick. You can cancel anytime from inside the dashboard. There is no annual commitment.
Every alert includes guided response steps in plain English. The first three or four are usually things you can do yourself in a few minutes. If it is bigger than that, the Pro plan includes consulting calls so a human walks you through it.
Not yet. Healthcare is walled off until our subprocessor BAA chain is fully executed. If you are a covered entity or business associate, please wait for that announcement before signing up.
