Everything we build.
One desk.
Not a list of services on a slide. A row of working doors, and each one opens with a free demo before you pay a cent. Shipped end to end, fixed scope, fixed quote, and you own everything on launch day.
The flagship // Free to try, yours in a week
A website, a voice agent, and the brain that runs them.
The three that work together. Forge all three free in about a minute, and the command center is free with either paid piece.
Websites
A site that captures the lead and follows up on its own. Not a brochure, an engine.

Straight answers // No sales call required
Questions, answered plainly.
What does Modern Mustard Seed build?
Productized doors that each open with a free demo (a website, a voice agent, a command center, a commercial, ads, print, a launch plan, and more), plus fully bespoke work: custom web and mobile apps, specialty AI tools, online stores, and agentic systems. Every engagement is shipped end to end by Sarah Scarano, fixed scope and fixed quote, and you own it.
How fast can you ship?
Websites, voice agents, and command centers go live in about a week from kickoff, and you can tour a free demo of each first, in your hands within the hour. Custom apps, software, and online stores usually take two to four weeks. Every engagement is fixed scope with a fixed timeline you see before work begins.
What is a specialty AI tool?
An industry-specific software tool that replaces an expensive recurring workflow. Examples: a FSBO command center that replaces a real estate agent commission, a deal analyzer that cuts investment evaluation from 2 hours to 90 seconds, a staging tool that finishes in under a minute. Specialty AI tools turn $3K service line items into $99 subscriptions.
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?
The productized doors show their price on each page (for example, a website is $497 setup plus $147 a month, and the command center is free with either). Bespoke apps, tools, stores, and agentic systems are quoted per project after a free discovery call. Pricing is fixed before work starts, with no hourly billing.
Pick a door. It opens free.
Enter your business once and tour a working website, a voice agent, and a command center, all with you within the hour. No card, no meeting.
