We build and fix AI agent systems for e-commerce websites and backends.

It’s easy to build an agent system that works in a demo and breaks once it scales.

Agent problems

Incorrect results

Agents are missing the inputs they need, so they guess.

Our fix

We give every agent the inputs it needs.

Cost overruns

Noise and duplication fill the input context.

Our fix

We trim the context to what matters.

Frequent failures

Instructions are so restrictive the agent gets stuck.

Our fix

We rebalance instructions and guardrails.

Excessive time spent

The agent/subagent graph is tangled.

Our fix

We restructure and reroute the graph.

Good technology alone is never enough, and neither is a checklist of tricks.

How we work

Put needs first

We start with your business needs and work backwards, looking at the whole picture.

Fix root causes

Instead of just patching surface problems, we fix their root causes so they don't just pop up again a week later.

Build for users

We design for the people. A system only works if your team and your customers can rely on it.

Services

What we build

AI agents for each part of an online store: selling, support, catalog and operations. Each one is built around a result you can measure.

AI Shopping Assistants

Increase sales

We build a conversational shopping assistant into your webpage, plus in WhatsApp and Instagram, that lets your customers explore your products in a more flexible and engaging way. It can also support sizing and fit questions, suggest bundles, and converse in the user's language.

Agentic customer service

Reduce support tickets

We build agents that let customers resolve order problems, plus initiate exchanges and returns, by enabling the agents to actually perform allowed actions instead of merely responding from FAQs. When the agent can't fully resolve something itself, it can hand over to a human.

Catalog Quality Agents

Keep your catalog complete and consistent

We build agents that create an accurate, comprehensive, appealing product catalog. This includes support for:

  • Finding missing product data
  • Adding SEO metadata and image alt text
  • Correcting inconsistencies in the data
  • Rewriting product descriptions for appeal
  • Correctly categorizing products
  • Adapting products to multiple markets (translation, localization)

Order Exception Handling Agents

Save hours on order problems

We build agents that handle the orders that don’t pass through the happy path. The agents can handle:

  • Payment problems
  • Orders stuck in supplier warehouses and carrier systems
  • Reacting to open-ended messages from customers
  • Watching inventory and resolving discrepancies
  • Flagging possible fraud
  • And many other unexpected hiccups in order fulfillment

Integration with External AI Shopping

Get discovered by AI agents

We analyze your system and determine how ready it is to support chatbots like ChatGPT, Claude, Gemini, and other agents, then build the systems to support integration with them, such as providing data that is structured best for AI and creating APIs to support AI-driven purchasing.

Questions

Common questions before starting.

What does it cost?

Discovery, pilot and rollout each have a fixed fee we agree together before work starts, so there are no surprises. The managed service is a monthly retainer.

What are your working hours?

We’re based in Portugal (Lisbon time) and work 10:00–19:00, with meetings possible until 21:00.

What happens in the 30-minute intro?

You tell us what you want to improve, or what your agents are getting wrong. We work out where an agent would help most, and you leave with a view on where to start.

What do you need from us to start?

Access to the systems the agents will touch, and someone who knows how your store runs day to day. The discovery and AI audit uses both to find the use cases with the highest return.

Can you work with our engineers?

Yes. We work alongside your engineers through the pilot and rollout. Afterwards your team can run the agents, or we look after them as a managed service.
