Everything we build.
One standard.
Not a list of services on a slide. Five disciplines practiced deliberately, and the departments underneath them that a working engagement actually reaches for. Designed and shipped end to end by the studio, and you own everything on launch day.
The flagship // Built as one thing
A website, a voice agent, and the brain that runs them.
The three that work together. Commissioned as one engagement, they run off one brain, which is why the answers never drift apart.
Websites
A site that captures the lead and follows up on its own. Not a brochure, an engine.

Every department // Reached for as the work needs it
The whole studio, one door at a time.
The Presence Audit
Most people decide about you before they reach your website. This grades all three: the site, the Google profile, and the reviews.

Get found and cited by ChatGPT, Perplexity, and Google AI Overviews. Graded, then fixed.
Open itMustard Mode
Learn to run Claude like the studio does. A live agentic coach across four tracks.
Open itWhen the answer is software nobody sells yet.
An application, a tool only your industry has, a store, or a system of agents. Same hand on it from first sketch to launch day, one set package price, and you own all of it.
Custom apps & software
Web and mobile apps built end to end. Frontend, backend, auth, billing, deploy. Real products that scale.
Specialty agentic tools
An industry tool that replaces an expensive recurring workflow. The costliest repeated task in a trade becomes software the operator owns.
Online stores
Headless commerce with custom design, an agentic concierge, and funnels that convert from day one.
Agentic systems
Multi-agent workflows and internal copilots that replace the human glue between your tools.
How we engage // Straight through, start to finish
You pay for the outcome, agreed up front.
One price, agreed in writing
You see the set package price and the timeline before any work begins, and the number does not move afterwards.
Changes are included
Adjustments to what we built are included, permanently. No change order, no second invoice, no conversation about whether it counts.
Shipped end to end
The people who scope it are the people who build it. No strategy decks that never become products, and no handing your project to somebody who has not read it.
You own it outright
The repo, the domain, the accounts, and every credential are yours on launch day. Keep us on a retainer or walk. No lock-in.
The full engagement model lives on How It Works.
Straight answers // No sales call required
Questions, answered plainly.
What does Modern Mustard Seed build?
Five disciplines: design-led websites and brand, custom software, voice agents, marketing, and retained advisory. Marketing covers social posting, blog writing, commercials, ad campaigns, email newsletters, and Google Business Profile upkeep. Inside those sit the departments the studio has built over time: command centers, commercials and brand films, ads, print, launch, specialty agentic tools, stores, and agentic systems. Every engagement is designed and shipped end to end by Sarah Scarano at a set package price, and you own the result outright.
How fast can you ship?
A website, a voice agent, or a command center is typically live within a week or two of kickoff. Custom applications, deeper software, and online stores usually run two to six weeks. Every engagement carries a fixed timeline that you see in the proposal, next to the price, before any work begins.
What is a specialty agentic tool?
An industry-specific software tool that replaces an expensive recurring workflow. Examples: a for-sale-by-owner command center that stands in for an agent commission, a deal analyzer that cuts investment evaluation from two hours to ninety seconds, a staging tool that finishes a room in under a minute. The pattern is the same every time: take the costliest repeated task in a trade and turn it into software the operator owns.
Do you build mobile apps as well as web apps?
Yes. Mobile apps for iOS and Android are built in one codebase using Expo and React Native. The same fixed-scope engagement structure applies as for web apps.
What is an agentic system?
A multi-agent workflow that replaces the human glue between disconnected tools. We use Trigger.dev for orchestration, Anthropic Claude for reasoning, and custom agents tuned for the specific operation. Voice agents are added when the workflow is phone-driven.
Do I own the code when the build is finished?
Yes, fully. You receive the repository, the live deployment, the domain, and every credential. There is no vendor lock-in and no per-seat fee. You can hire any other engineer to change it later.
What does it cost?
There is no price list on this site, because the right answer depends entirely on what is being built. Every engagement is scoped in one conversation and quoted privately as a set package price, agreed in writing before work starts. That number does not move, and changes to what we built are included permanently. Advisory is retained by the quarter.
Tell us which door you are standing at.
Or say what you are trying to make happen and we will tell you which one it is. Sarah reads every inquiry herself and answers inside one business day.
