AI Agent Development

We turn AI agentsinto products

Demos are easy. Products people use every day are not. We design the conversation flow, the memory, the retrieval, and the tool calls — then build the AI service and operate it ourselves.

Diagnosis

So it stops at the demo

We often hear that a team tried AI but could not get it into a real service. The reason is usually one of three. We design for all three from the start.

  • "Once the conversation gets long, it forgets what was said."

    We design the memory first

    Chat history and long-term memory are stored separately, and every turn decides what to read and what to write. Remembering a user across sessions is a design outcome, not a model capability.

  • "It sounds convincing, but there is nothing behind it."

    We make it search before it speaks

    Vector search finds the documents an answer should rest on, and the agent speaks only from what it found. When you can trace which document produced which answer, you can fix the wrong ones.

  • "As soon as numbers or rules come up, it gets them wrong."

    We never leave arithmetic to the model

    Rule-bound domains become separate, verifiable calculation engines, and the agent calls them as tools. The engine owns the calculation; the model owns the explanation.

Architecture

How the agent works

This is not a diagram drawn to explain something. It is what runs right now in a service we operate ourselves.

  1. Input

    Takes the question and the conversation so far

  2. Plan

    Decides what has to be answered and picks the tools

  3. Tool call

    Calls calculation engines and backend APIs for facts

  4. Memory

    Reads past and long-term memory, and writes this turn

  5. Answer

    Builds the answer on those facts and streams it back

  • Conversation graph

    Branches and retries are defined as a graph, so you can retrace what happened at which step.

    LangGraph
  • Long-term memory

    Chat history is kept per session; what the agent learns about a user goes into long-term memory. The graph decides what to read back on each turn.

    MongoDB
  • Document retrieval

    When a question needs grounds, the agent searches the document store first. Which documents fed an answer is logged.

    Qdrant
  • Prompt management

    Prompts live as data, not code. They can be changed without a deploy, and what changed when is recorded.

    Prompt Registry

Each service owns its own graph. Changing one service does not shake the others.

Process

How we work

What happens after you get in touch, and in what order.

  1. Inquiry

    Tell us what you want automated. An early idea is fine. We reply within one or two business days.

  2. Scope

    We decide what the agent will answer and what it will not. This is also where we tell you what today's technology cannot do.

  3. Agent design

    We settle the conversation graph, what to remember, which tools to call, and which documents to retrieve. What we agree here becomes the build spec.

  4. Build

    The agent and the product are built together. Progress is shared as a screen you can actually talk to.

  5. Launch

    We ship to production and wire up conversation logs, response latency, and error visibility.

  6. Operate

    We read real conversations and tune the prompts and retrieval. Answer quality rises here, not at launch.

Difference

What is different

We compared approaches, not companies. Which one is right depends on the problem you are solving.

Standard

A working demo takes a day. Being used daily is the work after that.

Our work starts where the demo ends. We read real conversations to find where answers wobble, rethink what to remember and what to retrieve, and fix the order in which tools are called. Because we operate what we build, this is a standard we hold ourselves to, not just one we ask of others.

Is there an agent you want built?

Tell us what you want automated, or what questions it should answer. We will map out what is possible and what today's technology still cannot do.
