Meet Sarah ↗About the studio
Faith meets function.
A direct line to the people who build it.
I'm Sarah Scarano, Agentic Developer and Creative Director at Modern Mustard Seed. Modern Mustard Seed is two people: I design and build, and my husband, Anthony Scarano, runs sales and marketing. You reach the two of us directly, with no account managers in between, from the first conversation to the finished detail.
We are a boutique design and product studio in Kalispell, Montana. We design and build websites and brands, voice agents that answer and book every call, custom software and agent systems, and Claude connectors for software companies, for businesses across the United States, managed for you end to end.
The team
Two people, one studio. A direct line to both.
Sales / Marketing
Anthony Scarano
Anthony Scarano leads sales and marketing. He helps you choose the right build, then keeps your marketing moving once it is live.
Book a call ↗Why we do this
Good software was priced out of reach for too long. We are here to end that.
The corner shop. The founder with one real shot. The operator drowning in busywork. They were all told that serious tools were for companies with serious budgets. That is over. Putting an elite product in the hands of someone who was never supposed to afford one is the work we love most.
The standard we hold
Excellence, every time.
Small beginnings, outsized outcomes. Faith and execution in the same hand, on every project and every line of code.
- 01
Ship complete
We hand over finished, polished work. No drafts, no almost-done, no "we will fix it later."
- 02
Design like it matters
Every screen is held to an Apple and Linear bar. We never ship the generic template look.
- 03
Honest and flat
One set package price, agreed before we build. Refinements to what we built are included.
- 04
You own everything
The code, the accounts, the keys. When we are done, it is yours, free and clear.
What we build
Six doors, one standard.
- Everything We BuildWebsites, receptionists and agents that answer, book and follow up.
- Websites And BrandDesign-led, built to be found, with a clear offer and an obvious next step.
- Voice AgentsA phone line that answers every call, day and night, and books the job.
- Custom SoftwareThe one clean tool built for exactly how your business runs.
- MarketingSocial, blog, ads and email, written in your voice and published on schedule.
- AdvisoryRetained counsel by the quarter on what to build and where agents belong.
“If you have faith as small as a mustard seed, nothing will be impossible for you.”
The tools we build on
Next.js · React · TypeScript · Tailwind · Supabase · Stripe · Vercel · Trigger.dev · Anthropic Claude · Gemini · Vapi
One refined stack across every engagement, proven in production every week. We do not chase frameworks. We compound.
Who we work with
Founders building something meant to last. Service businesses ready to get out of the inbox. Creators who treat their brand like a moat. People with a clear vision who need a partner that can actually ship.
With love, Sarah
Modern Mustard Seed
