Trellistry

The structure behind people-centred work.

Trellistry handles the admin behind rosters, camp and event registration, member and client records, and follow-ups. Your team spends less time chasing replies and fixing spreadsheets, and more time with the people you serve.

It works over WhatsApp, Telegram or Facebook Messenger. Volunteers don't need a new app or a login.

For churches, family service centres, counselling practices and schools.

3-month guarantee. If it isn't working for you, we fix it for free or refund you in full.

A trellis with a vine growing along it — the structure that holds up living growth.

It starts with knowing your people.

Most organisations come to us asking for a better membership or client list. The list is only the start. You need it to plan events, fill rosters and follow up with people who need help. All of that falls apart when the information sits in five different spreadsheets.

One record for each person

Contact details, household, attendance, serving and follow-ups are kept together. Update them once, and every roster, camp list and follow-up uses the new details.

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.

What this looks like in a normal week

Sunday roster for the children's church team, showing an automatic replacement, each volunteer's safeguarding status, and a WhatsApp chat where a volunteer agrees to cover.

Friday, 9.14pm. Someone pulls out of Sunday's roster.

Rachel replies on WhatsApp that she can't make it. Trellistry asks the next person on her team who is free and cleared to serve. Ben says yes 17 minutes later. The coordinator only hears about it if nobody accepts.

Family camp dashboard, showing registrations against capacity, one family registered together with their room, bus and matched payment, and lists ready for the committee.

Camp registration opens at 10am.

Parents register the whole family in one go. Families are placed in rooms together, and payments are matched automatically. By the time registration closes, the committee already has the rooming list, bus list and dietary summary.

A caseworker's short note turned into two follow-ups with owners and due dates, with a supervisor view showing counts only, and a phone reminder.

A quick note after a home visit.

The caseworker types "chase Mdm Tan re hosp visit, also her son". Trellistry turns that into two follow-ups, each with an owner and a due date, and sends reminders one at a time until they are done. If she changes jobs, the follow-ups go to whoever takes over.

What Trellistry Operations does

Trellistry Operations. Six modules, one system.

Start with Core Access, which includes People & Membership. Add other modules when you need them. Care & Follow-Through, Partner Network and Private AI can also be used on their own.

Core Access · People & MembershipStart here
ServingEventsCare*Partner Network*Private AI*Add what you need

People & Membership

One up-to-date record for each person. Every other module uses it.

  • Households, contact details and consent in one record
  • Forms that update the record directly
  • Flags duplicates and missing details
Included with Core Access
Learn more →

Volunteer & Serving Operations

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

  • Collects availability over WhatsApp, Telegram or Messenger
  • Finds a replacement when someone drops out
  • Only asks people who are cleared to serve

Proof point: Used in a 2,500-member Singapore church. 2,546 serving slots filled, 14,121 messages sent automatically, and about 200 hours of coordination saved a month.

From S$79/month

Events & Camps

Everything that happens after the registration form is submitted.

  • Families register once and are placed together
  • Payments matched to your payment gateway
  • Rooming, transport and dietary lists prepared for you

Proof point: One camp of about 1,500 campers, with admin work cut by more than half.

Care & Follow-Through

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

  • Picks out follow-ups from the notes and calendars you already keep
  • Sends one reminder at a time until it's done
  • Hands open items over when someone leaves

Works alongside your existing systems. Care & Follow-Through reads the calendar, notes and documents your team already uses; it does not replace a clinical, statutory or case-management system of record. Our data-centre inspection offer and no-content-logging clause cover content stored in Trellistry; the handling of content it reads in your own systems is set out in your service agreement.

From S$79/month

Partner Network

Share halls, trainers and programmes with other organisations.

  • Book halls from partner organisations on one calendar
  • Share trainers, speakers and programmes
  • People can join another organisation's programme without a new account
From S$49/month

Trellistry Operations · Private AI

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

  • Drafts minutes, case summaries and handover notes
  • Runs in our own controlled environment, not a public AI service
  • Every output stays a draft until a person approves it
From S$79/month

Ease of use

Easy for your team to use.

  • 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 on WhatsApp, Telegram or Facebook Messenger
  • 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

Design Workshops

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.

Private AI

Keeping AI private takes more than a private server.

Sensitive chats, case data and meeting summaries are processed in our own controlled environment. They are not sent to outside AI services. We also set the rules around it. These cover which records each request can read, who is allowed to ask, and how long anything is kept. A person reviews every output before it is used.

1. Subscribe

A governed environment we run, with your policies applied. From S$79/month.

2. Learn to run your own

Build your own capability — server, workstation, or the devices you already own. From S$3,500.

3. We build and run it for you

Customer-owned infrastructure, for organisations whose governance requires it. From S$25,000, quoted to scope, plus S$800–1,500/month.

Training

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.

See our training →
Privacy

The work AI helps with most is often the most sensitive.

We run our own AI server. Sensitive chats, case data and meeting summaries are processed there, so they don't need to go to outside AI services. This lowers the risk of exposing information about vulnerable people.

You shouldn't have to gamble a year's budget to find out whether this works.

The Trellistry Operations guarantee.

Try it for three months. If it isn't working, we fix it free — or refund your subscription in full and hand back a clean export of your data. No lock-in.

And it should cost you less than the alternative. Before you start, we agree a baseline with you: what your team currently spends on administration, in hours or in dollars, whichever you'd rather be measured on. If that baseline hasn't fallen after three months, the same refund applies.

Applies to the Trellistry Operations subscription. Professional services are covered against the scope agreed in writing for that engagement. Kingsfold memberships and subscriptions are separate products and are not covered. Donors, investors and supporters interested in Kingsfold are welcome to contact us.

Kingsfold — a Trellistry product

The decision layer for Protestant philanthropy across Asia.

Good ministry work often goes unfunded. Sometimes donors never hear about it. Sometimes they hear about it, but have no reliable way to judge it. Kingsfold checks organisations and their funding needs, so donors and their advisers can decide based on evidence.

Beyond Hours Saved

The better question to ask.

Most conversations about AI stop at cost and time. Speaking to financial institutions about AI adoption, Singapore's Deputy Prime Minister and Minister for Trade and Industry, Gan Kim Yong, argued that cost 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.
