Build what the calling needs. Until all have heard.
Design, technology and marketing for ministries, churches, charities and organizations that serve the Kingdom, at ministry pricing. Modern Mustard Seed and Cross + Covenant work side by side: curated merch collections, stores, the systems to run it all, and the launch that shares it with the world.
What we build together
One mission, four ways in.
Curated merch collections
Three to six designs under your name with Cross + Covenant, on their store or your own. Made to order, so no inventory, no setup fee and no minimum. When supporters buy from your collection, your organization earns 40% of the profit on every piece. When you order 12 or more of one design yourself, for an event or a team, you pay 30% off retail.
See Your Own CollectionStores and websites
A storefront or a website that looks like the calling behind it, with giving, events and sign-ups built in. Designed bespoke, never a template, and yours to own.
Operating systems to run it all
The back office a small team should not have to carry by hand: supporters and volunteers in one place, event sign-ups, follow-up that goes out on time, and an AI front desk that answers every call.
Marketing and launch
A plan to share it with the world: social posting, email, films and campaigns, written in your voice, so the work reaches the people it is for.
How our marketing worksTwo studios, one mission
Made for impact, not for margin.
Modern Mustard Seed is the design, creative and engineering studio: the brand, the store, the systems and the launch.
Cross + Covenant is the Christian apparel brand that designs, produces and ships your collection, made to order, and puts 10% of the profit on every order toward our Charity of the Month.
Same founder, same conviction: the good news belongs in every place people look, and the ministries carrying it deserve work as beautiful as the message.
Ministry pricing
Set packages, at a reduced rate for Kingdom work.
Scoped in one conversation, quoted as a set package price in writing before work starts, and it does not move. Changes to what we build are included. You own all of it.

Questions from ministries.
Who is this for?
Churches, ministries, missions organizations, Christian charities and faith-based nonprofits, and the creators and leaders serving alongside them. If your work serves the Kingdom, this is the door.
How does ministry pricing work?
The same way every engagement here works, at a reduced rate. We scope it in one conversation and quote a set package price in writing before work starts. It does not move, and changes to what we build are included.
Do we have to buy inventory for a merch collection?
No. Collections are made to order through Cross + Covenant, so there is no inventory, no setup fee and no minimum. Two numbers do two different jobs. When supporters buy from your collection, your organization earns 40% of the profit on every piece: the profit is what is left after the garment cost and the 10% of profit that goes to our Charity of the Month, which works out to $8.77 on a $40 tee. When you buy for your own event or team, 12 or more of one design to one address, you pay 30% off retail, so a $40 tee is $28.
How do Modern Mustard Seed and Cross + Covenant work together?
Modern Mustard Seed is the design, technology and marketing studio. Cross + Covenant is the Christian apparel brand that produces and ships your collection. One founder, one mission: until all have heard. And 10% of the profit on every Cross + Covenant order fuels our Charity of the Month.
Do we own what you build?
Yes. The website, the store, the systems, the accounts and the code are yours. We build assets you can run without us, not a dependency on the studio.
