The structure behind people-centred work.

The trellis behind thriving ministry.

Operations software, design workshops, hands-on training and private AI for organisations that look after people — churches, family service centres, counselling practices and schools. Less time coordinating, more time with the people you serve.

Membership and client records, staff and volunteer rosters, camps and programmes, care follow-up that chases itself, and resource sharing between organisations — run over WhatsApp, on one system your team can actually use.

3-month guarantee — if it's not working, we fix it free or refund you in full.

Start with your people records. Get back to the work that matters.

Most organisations come to us asking for a better people database. That's rarely the real goal. The reason to know your people well is so you can gather them, run the programme, get more of them involved, and care properly for the ones who need it most — and every one of those breaks down when your records are scattered across spreadsheets.

One person record

Groups & community

Know who's connected and who isn't, so no one falls through the gaps.

Camps, programmes & events

Registration reads from the same record — no duplicate data entry.

Staff and volunteer rosters

Pulls from the same people record, so you roster the person, not a name in a spreadsheet.

Care and follow-through

Follow-up is attached to a real person with history, not a sticky note.

Six modules. One system.

People & Membership

One governed record for every person, that every other module reads from.

What it does

  • Stores households, relationships, contact preferences and consent in one record
  • Segments people by group, ministry, life stage or attendance pattern for targeted messaging
  • Runs custom forms (sign-ups, consent, updates) that write straight back to the person record — no re-typing
  • Flags duplicates, missing contact details and stale records so your data stays usable
  • Controls who can see what, with role-based permissions down to field level

Replaces: the master membership spreadsheet and the four out-of-date copies of it.

Volunteer & Serving Operations

Rostering that chases people so your coordinator doesn't have to.

What it does

  • Collects availability from staff and volunteers over WhatsApp, with automatic reminders to non-responders
  • Builds and publishes rosters against your own rules — team, ministry, frequency, blackout dates
  • Sends confirmations and shift reminders automatically before each serving date
  • Finds and requests a replacement from the same team when someone drops out
  • Keeps serving history per person, so you can see who is over-serving and who has never been asked
  • Escalates to the coordinator only when automation can't resolve it

Replaces: the roster spreadsheet plus the WhatsApp group where nobody replies.

Proof point: One live deployment at Adam Road Presbyterian Church allocated 2,546 serving slots, engaged 490 parents at a 69% response rate, and sent 14,121 automated messages — roughly 200 hours a month (about 7 hours a day) of manual coordination avoided.

Events & Camps

Everything that happens after the registration form is submitted.

What it does

  • Runs conditional registration — different questions by age, ministry, role or first-timer status
  • Groups families and households automatically so they register once and are placed together
  • Tracks payment status and reconciles against your own payment gateway account
  • Enforces capacity limits, waitlists and priority rules without manual sorting
  • Collects and reports transport, rooming, dietary and accessibility needs in one place
  • Produces the rooming list, transport manifest and dietary summary your committee currently builds by hand

Replaces: the Google Form, the payment tracking sheet, and the camp spreadsheet nobody wants to own.

Proof point: One camp deployment supported ~1,500 campers, with over 50% reduction in administrative workload and registration approaching capacity within two hours of opening.

Care & Follow-Through

Makes sure the person who most needs a call actually gets one.

What it does

  • Reads the places your team already writes — calendar entries, meeting notes, shared documents — and finds the commitments buried inside them
  • Learns your team's own shorthand and conventions during setup, shows you every rule it has inferred, and acts only on the ones you confirm
  • Turns "I said I'd call her back" into a tracked item with an owner and a date, without anyone breaking off to file it
  • Brings one next action at a time over WhatsApp, at a moment the person can act on it, and keeps chasing until it moves or is deliberately dropped
  • Assembles the picture before a visit, session or meeting: last contact, what is still outstanding, what you meant to raise
  • Works across a team: a supervisor sees what is owed and what has gone cold without reading the notes themselves
  • Keeps the follow-through record against the person's record, with a full access audit trail and your own retention and deletion rules
  • Runs read-only if you prefer: it changes nothing in your systems, checks whether you did it yourself, and keeps reminding you until you have

Replaces: the mental list of people you keep meaning to call back — and the handover note that never gets written.

Partner Network

Share rooms, people and programmes with peer organisations instead of duplicating them.

What it does

  • Lists your available spaces and lets partner organisations request bookings against a shared calendar
  • Shares a directory of trainers, speakers, facilitators and specialists across the network, with availability
  • Publishes courses, camps, conferences and training events that partner organisations can open to their own people
  • Lets a parent body or network administrator control who can see and book what — or run it open, if you prefer
  • Handles cross-organisation registration, so someone from one organisation can join another's programme without a separate account
  • Reports on what's being shared, so a central office can see where resources are going unused

Replaces: the email chain asking whether anyone has a hall free on the 14th.

Trellistry Private AI

Use AI on your most sensitive material without sending it to an external service.

What it does

  • Processes sensitive chats, case data and meeting summaries within our controlled environment — not sent to external AI services
  • Generates draft meeting minutes from authorised recordings: decisions, action items, follow-ups
  • Summarises case notes and drafts handover documents when staff change
  • Searches your own policies, handbooks and internal documents
  • Translates resources between languages
  • Reconciles and merges spreadsheets, generates timetabling drafts and reports

Your team can actually use this.

  • Role-based home screens — a volunteer coordinator, a pastor or caseworker, and an administrator each land on a different view showing only what they need
  • The numbers a leader actually asks for — attendance trend, serving load, upcoming camps, open follow-ups — on one screen, no report-building
  • Filter and export anything you can see; nothing requires a query language or a support ticket
  • Volunteers never need to log into a dashboard at all — they respond over WhatsApp
  • Designed to be usable on a phone, because that's where your volunteers are
  • Every rollout includes hands-on training for your team, and we stay past go-live

We might tell you not to buy our software.

A design workshop maps the real workflow, names the friction points, and produces a written recommendation — which might be one module, a better use of what you already own, or nothing at all. We invoice for the workshop whatever it concludes.

From S$3,500 for a one-day workshop.

Training isn't the add-on. It's half the work.

Most vendors hand you a system and wish you well. We teach, coach and mentor — and we run workshops as a standalone service too, whether or not you ever license our software. Adoption training during rollout is included with every subscription.

AI helps most with the work you cannot safely send it.

We built our own AI server on-premises so sensitive chats, case data and meeting summaries can be processed within our controlled environment, reducing the need to send sensitive information to external AI services and lowering certain data-exposure risks that could put vulnerable or sensitive communities at risk.

The better question to ask.

Most conversations about AI stop at cost and time. Speaking about how firms should adopt AI, Singapore's Deputy Prime Minister and Minister for Trade and Industry, Gan Kim Yong, argued that this is only half the question.

"they should not only ask: how much cost can we save?"

— Gan Kim Yong, Deputy Prime Minister and Minister for Trade and Industry, Singapore, 20 May 2026 (source)

He went on to ask what new roles could be created, how existing workers could be trained for them, and how people across an organisation could use AI to do work of higher value.

We think that question matters more in a church, a school or a counselling practice than it does in a bank. The hours we hand back are not the product. What your people grow into is.
