The one who changed your life

Somewhere, someone changed the course of your life.

It was the third-grade teacher who stayed after the bell.

01  /  Why Custos

Work buries you.

Teachers carry what one generation knows to the next. Today they spend their nights on paperwork that was never the point: planning templates, standards tags, review cycles. We refuse to accept that. Custos Practice exists to take the busywork off teachers, so they get back to the work only they can do.

The mission

Teachers deserve the best tools on earth.

Today they're the last people edtech is built for. We start with them.

02  /  What Custos is

Custos Practice builds in the room, beside the teachers who will use it, around the way their district already works.

Our tools carry the paperwork and leave the teaching to teachers. We call that Guidance AI. Trellis, for curriculum, is the first.

03  /  Our first product

Trellis.Curriculum, built with teachers.

Trellis carries the paperwork around a course, from standards to review, and leaves the course itself to the teacher. In Danbury Public Schools, a unit curriculum review went from 90 minutes to 15.

04  /  The practice

Three ways we clear the grind with you.

01

Consult

We come to your district in person and learn how you build curriculum and what your frameworks are.

02

Build

We fit the tool to those frameworks, beside the teachers who will use it.

03

Train

We run PD days in your district to get your teachers onboarded, leave them confident running it, and keep it running. When there's new ground to cover, we come back in person.

05  /  What makes Custos different

Built in the room, beside the people who will run it.

No remote-only delivery. No templated rollouts. The tool that ships matches the work as it is actually done, because it was built next to the people who do it.

Next Generation Learners — teaching the full class

Brayan Tenesaca training in the ring
06  /  The story

He didn't wait for permission.

While the world argued about whether AI belonged in classrooms, Brayan put it in kids' and teachers' hands. At eighteen, he founded Next Generation Learners and brought real AI tools to public libraries across Connecticut. No budget. No permission. No waiting.

Custos Practice is the next move. The same fight, aimed at the paperwork that keeps teachers from teaching. It started in Danbury, where a curriculum director asked for help and teachers were writing in Trellis within weeks. It won't end there. You build with Brayan directly, from the first conversation on.

07  /  Questions

What people ask before they start.

01What does it cost?

Every district starts with an in-person build fitted to its own frameworks, then a yearly hosting fee that grows with what the tool covers. The quote comes after we've seen how your district works.

02How long does it take?

Four weeks to a working tool is a realistic target. Trellis, the curriculum builder Danbury Public Schools runs today, went from first conversation to teachers writing in it in four weeks.

03Why not just buy something off the shelf?

The tool that fits your work usually does not exist yet. A Custos build starts from how the work is already done, in the room with the people doing it, and the tool fits them. That fit is the whole product.

04What do we own?

Your data is yours, and it's handled under a data privacy agreement written for your district.

05What happens when the engagement ends?

You pick between two paths. Your own team runs the tool, which is what Train exists to make possible. Or Custos keeps it running under a hosting and warranty agreement. You can move between them later, in either direction.

06How is student data handled?

Under a data privacy agreement written for how your district actually works, settled before anything is built.

07Do you work remotely?

Delivery happens in the room. What ships matches the work as it is actually done, because it was built next to the people who do it.

08Who does the work?

Brayan, directly, from the first conversation through the final handoff.

09Who do you work with?

Public school districts first. Recent work includes Danbury Public Schools, Woodstock Public Schools, Wooster School, Danbury Public Library, Ridgefield Library and Babson College.
