FideiLabs builds Catholic technology products. Catholic OS is the flagship platform — one diocese agreement for schools, parishes, and central office.
An AI-native technology company rooted in twenty years of Catholic institutional work. One shared family record across every brand in the suite.
We started OptionC because Catholic schools deserved software built by people who understood sacramental records, tuition assistance, and diocese reporting, not a public-school product with a cross pasted on.
Twenty years later, that same team runs FideiLabs. Every brand decision still starts with the question: does this help a Catholic institution serve families better?
Technology contracts are stewardship decisions. The records of children, the finances of a parish, and the data of a diocese deserve a vendor who treats them that way.
- Saint of the Day on every staff login
- One family record linking school and parish
- Diocese-wide rollout from a single agreement
- Lower payment rates through Matt Money
What is Catholic OS?
Catholic OS is how a diocese buys everything FideiLabs offers: school SIS, parish management, payments, safety alerts, AI, and partner integrations under one contract instead of negotiating with six separate vendors.
Your schools and parishes share one family record. Your staff gets one login. Your CFO gets one invoice.
School and parish share one family record
Enroll a student and the parish household updates automatically. No re-entry, no mismatched addresses.
Aquinas AI from the same login
Teachers, pastors, and admins open Aquinas without a separate account: study tools, homily prep, and devotional content where they already work.
CatholicLogin single sign-on
One username across OptionC, Matt Money, ARC Alert, and partner tools, managed diocese-wide through Okta.
Matt Money for tuition and offertory
Payment processing built into every product. Most dioceses see lower rates than their current processor.
Six brands. One diocese agreement.
Each brand serves a different part of Catholic institutional life (schools, parishes, payments, safety, AI), but they share one family record and one login.
Gradebooks, attendance, tuition, and diocese reporting, built for Catholic schools since 2004. Saint of the Day on every staff login.
See OptionC SchoolSacramental records, giving, and parish registration tied to the same family record as the school. When a child enrolls, the parish already knows the household.
See OptionC ParishStudy tools, devotional content, homily prep, and image generation for teachers, pastors, and families. Launching Fall 2026.
Visit Aquinas.comTuition, offertory, and event payments across every FideiLabs brand. ACH at 1.5%, credit cards at 3.5%. One processor for the whole diocese.

Request a meetingFor diocese and institutional partners with specialized needs, FideiLabs offers custom technology development rooted in twenty years of Catholic institutional knowledge. We accept a limited number of custom engagements each year. Contact us to discuss your diocese's specific requirements.
“When we switched to OptionC, our principals stopped re-entering the same family data in three different systems. That alone changed how our office staff spent their week.”

Secular vendors serve Catholic schools too. Here is the difference.
Most dioceses evaluate FACTS, Pushpay, or ParishSOFT alongside OptionC. Those are capable products, but they were not built for the way Catholic institutions actually work.
FACTS / Nelnet
Strong tuition and SIS bundle for schools of all types. Catholic identity is not part of the product. FideiLabs includes Judicious, free financial aid tools built into OptionC.
Pushpay / ParishStaq
Large Catholic parish customer base and modern giving tools. No school SIS, no shared family record with your diocese schools. FideiLabs connects parish and school data in one place.
ParishSOFT / Ministry Brands
Deep parish management across many dioceses. No school information system, no unified record when families move between parish and school. FideiLabs covers both under Catholic OS.
Built for Catholic Institutions
Twenty years of Catholic school relationships. School SIS, parish management, payments, safety alerts, and AI, designed together and sold under one diocese agreement.
Khan Academy, Paycor, and Array, inside Catholic OS.
Your diocese already knows these names. Catholic OS brings their capabilities into the same login and contract as OptionC and the rest of the FideiLabs portfolio.
Khan Academy curriculum inside OptionC. Teachers assign lessons from the same gradebook they use for attendance and report cards.
Planned for Catholic OS, 2027Diocese payroll and HR through Paycor, accessed with the same CatholicLogin credentials as your schools and parishes.
In developmentCredit monitoring and identity protection for diocese staff and families, offered as a FideiLabs benefit, not a separate vendor signup.

Two Decades in Catholic Education
OptionC has served Catholic schools exclusively. No public districts, no secular clients. Every feature request comes from a principal, pastor, or superintendent we already know.
One Family Record
When a child enrolls in a Catholic school, the parish record updates automatically. No duplicate entry, no lost sacramental history, no asking families to register twice.
Catholic Life on Every Screen
Saint of the Day greets staff each morning. Liturgical calendars, Catholic content, and parish-school connections are part of the product, not a settings toggle added later.
One Agreement, Every Institution
A superintendent or vicar general can bring every school and parish onto Catholic OS with a single contract, not six separate vendor negotiations.
What would Catholic OS look like in your diocese?
Whether you oversee twenty schools or two hundred parishes, we start with your current vendors, your pain points, and what a single agreement could simplify.

A Catholic technology company with twenty years of operating history.
FideiLabs is not a concept deck. OptionC has served Catholic schools since 2004, and the product portfolio is expanding into parish management, payments, AI, and diocese-wide platform sales through Catholic OS.
Years Operating
OptionC has served Catholic schools since 2004. FideiLabs is expanding a business with existing customers and relationships, not entering a market cold.
Brands Shipping or Near Launch
School SIS, parish management, payments, safety alerts, and AI are built or in active development. Capital goes toward growth and diocese rollout, not greenfield R&D.
Catholic-Native Competitor at Scale
Secular vendors serve Catholic institutions, but none were built exclusively for them. FideiLabs occupies a category that did not exist before.
Dioceses in the US
Each diocese is a potential Catholic OS customer: schools, parishes, and central offices under one agreement. International expansion follows the same model.
