The T1TAN Story

T1TAN was founded in 2010 in Herbolzheim, Germany. The brand makes goalkeeper gloves and other goalkeeping gear and sells them through its own online store. Its customers range from amateur keepers all the way to pros.

We've worked with T1TAN for two years now, and for the past year that has included customer service on armincx. T1TAN gets a lot right in support. The team replies within about 2 hours on average, and several AI agents were automating around 40% of support work. Most messages are about returns, product complaints and shipping status, plus a steady stream of invoice requests.

T1TAN wanted automation to go deeper. So we sat down together, took a close look at the setup and rebuilt it. Today, a First Level AI agent picks up every request, backed by subagents for each topic. The team keeps refining the setup as they go.

"I just feel a lot more efficient. The agents really take a lot off our plate, and I can put that time into other things."

What changed with the switch

From several topic agents to one First Level AI agent that takes every request and brings in the right subagents.

before the switch

after the switch

One agent per topic

T1TAN had several AI agents running side by side, each with its own topic and its own trigger. For the classic support topics, that worked well.

Mixed requests landed with the team

Only one agent ever owns a conversation. When a customer wrote about two things, one agent handled its own topic and the team picked up the rest.

Waiting over the weekend

Anything the agents didn't cover sat there until the team was back. On weekends, that meant customers sometimes had to wait for a reply.

Around 40% automation

A solid number, and the foundation for the next step.

How T1TAN rebuilt its setup

To see where T1TAN could automate more, we sat down with the team and went through the existing setup. Together, several topic agents were automating 42% of requests. The biggest lever for more automation was a new structure.

Step 1: Sort the topics

Most T1TAN customers write about returns, product complaints and shipping status. On top of that come lots of invoice requests and messages outside classic support, like sponsorship inquiries. These topics form the backbone for the subagents in the new setup.

Step 2: One First Level AI agent as the entry point

Every request goes to the First Level AI agent first. It reads the message, works out what the customer actually needs and ignores side remarks or issues that are already resolved. It owns the entire conversation and writes the reply to the customer. When a case needs a decision from the team, it hands the ticket over with all the verified facts.

Step 3: Subagents bring the facts

Behind the First Level AI agent, subagents each handle one job. They pull data, check rules and report back what they found. The reply to the customer always comes from the First Level AI agent.

Here's an example. On a Saturday evening, a customer writes that their package hasn't arrived and they need the invoice. The First Level AI agent spots two requests and asks two subagents. One finds the order in Shopify and pulls the tracking from DHL. The other grabs the invoice from Billbee. The customer gets one reply with the delivery status and the invoice attached.

In the old setup, a topic agent would answer its part of that request. The rest waited for the team until Monday.

"The customer benefits most when they get everything they need in one reply, shortly after reaching out. On weekends especially, a fast response makes even more of a difference."

The strategy behind it

Four building blocks T1TAN uses to take automation deeper.

AI in auto-send mode

AI in auto-send mode

For repetitive requests with a clear answer, the First Level AI agent can be set to “Always run” after an initial test phase. It then sends its reply without approval. That way, customers get an instant answer to standard requests.

Direct system integration

Direct system integration

Shopify is T1TAN's store platform and connects directly to armincx. Billbee supplies the invoices, DHL the tracking. That way, the agents work with real order data on every request.

Draft replies for sensitive topics

Draft replies for sensitive topics

When a case needs a decision, the team stays in the loop. These actions are set to “Ask every time”. The agent prepares everything, and the team approves the reply with one click or adjusts it.

Continuous AI training

Continuous AI training

The T1TAN team reviews real tickets on an ongoing basis and fine-tunes the details. On top of that, our armincx team put together a playbook with recommendations. Every change can be tested before it goes live, and the run history shows for each ticket why the agent made the call it did.

A connected tech stack

armincx plugs into T1TAN's existing stack. Six integrations make up the setup.

The numbers

40–42%

Automation rate before the switch

With several topic agents, AI was handling 40 to 42% of T1TAN's support work. The new setup builds on that.

~2 hrs

First response time

The T1TAN team replies within about 2 hours on average. With broader automation, customers now get an instant answer more often on weekends too.

>50%

Goal after the switch

With the switch, T1TAN wants to get past 50%. The team keeps developing the setup to get there.

"We wanted to push our rate even higher and rebuild the setup. Fewer individual agents, and more of a First Level agent that covers everything."

Your support, on autopilot.

armincx takes care of the routine so your team can focus on what really matters.

Take the load off your team

AI handles the routine. Order status, tracking, returns, invoices, all fully automated. Your team has room for the cases that need judgment and empathy.

Instant replies. Around the clock.

When a reply runs fully automated, it goes out right after the request comes in. At night, on weekends, after a launch. The AI never sleeps, so your team finally can.

Continuous AI training

Your team gives feedback on individual replies, and rules and knowledge get sharper over time. Every change can be tested before it goes live. So the share the AI handles grows with every process you switch on.

At T1TAN, every request goes to the first-level AI agent first. It identifies the actual concern, calls on several subagents when needed and writes the reply to the customer. The subagents fetch the facts, such as the order from Shopify, tracking from DHL or the invoice from Billbee.

Yes. When a T1TAN customer writes that a package is missing and they need the invoice, the first-level AI agent recognizes two concerns. One subagent pulls tracking from DHL, another gets the invoice from Billbee. The customer receives one reply with the delivery status and the invoice attached.

Yes, T1TAN shows it with 40 to 42% of support work automated. Returns, complaints and shipping status are the most common requests and can be answered automatically with connected shop and shipping data. Dennis Fietzeck says the agents really take a lot off the team’s plate.

Yes. In armincx, every action of an AI agent has its own mode. If “Send reply” is set to “Always run”, the reply goes out directly, even at night and on weekends. Sensitive cases stay on “Always ask”, so the agent prepares everything and the team approves it. T1TAN uses this to answer standard requests instantly.

Topic agents each have one topic and their own trigger, with exactly one in charge per conversation. In armincx, a first-level AI agent takes every request and calls on several subagents when needed, so one reply covers mixed concerns too. T1TAN aims to reach over 50% automation this way.
