A custom agent that does the work, not a chatbot that only answers
A rule repeats until an exception breaks it. An AI agent reasons over a goal and acts on its own. dotfun's AI agent development services build that agent for you, wired into the tools your team already runs.
You do not need another bot.
You need something that does the job.
Most teams already tried the easy version, and it did not hold.
The chatbot only talks.
It answers a scripted question and stops. Ask it to update a record, and it cannot.
A conversation, not a worker.
The simple automation breaks on the exception.
A fixed if-this-then-that rule works until the input changes, then it stalls quietly. Rules do not reason.
They repeat.
The DIY platform sits unused.
Building the agent turns out to be a real project nobody has time for.
The license renews; the agent never ships.
The offshore build does not fit.
You handed a spec to a staff-aug shop and got code that runs
But does not understand how your business works.
You do not want a toolkit.
You want the thing built, wired in, and working — and that is what our AI agent development services exist to do.
What you get from dotfun's AI agent development services
A custom agent that reasons over a goal and acts inside your stack. Done for you, senior-led, and wired to the funnel so the work shows up in pipeline.
It reasons over a goal, not a script
A custom agent is given an outcome, not a decision tree. Tell it to "qualify this inbound lead and book the next step," and it reads the context, works out the steps, and knows when to ask a person (IBM and Google Cloud define an agent the same way).
It works inside the tools you already run
An agent that lives in a demo is useless. We build agents that read from and write to your CRM, helpdesk, and database. The wiring is the hard part, and the wiring is what we do.
It handles the variation a rule cannot
Real work is messy. Inputs vary and edge cases show up daily, and a rule stalls on all of it. An agent reads the situation, adapts, and either finishes the task or escalates it cleanly.
It is built for you, not handed to you
This is not a platform where you assemble the agent yourself. Our senior team scopes, builds, grounds, tests, and ships it. You do not need an in-house AI engineer to run it.
The work AI agents for business actually take off your team
Capability examples: repetitive, judgment-light work that still needs to read context and act.
Reads a ticket, pulls the account context, drafts a first reply, routes the hard ones to a person.
Dedupes, fills gaps, updates stages, flags what looks off.
Reads an inbound lead, asks the qualifying questions, routes it to the right owner.
Gathers what is scattered across your tools and drafts the reply or brief a human approves.
Reconciliation, status updates, handoffs between systems.
How dotfun builds a custom AI agent, start to finish
No black box — the path from a workflow that hurts to a working agent you own.

Which task, what inputs, and where a human stays in the loop. If a custom build is not the right answer, we say so — sometimes the AI Audit or a productized Iris option fits better.

We connect it to your real sources so its answers come from your business, not a general guess.

We build the connections into your CRM, helpdesk, and tools so the agent reads and writes where the work lives.

Before an agent touches a live customer or a real record, we test it against real cases and set the escalation rules.

We watch how it performs, correct what drifts, and extend it as the work changes. You own it.

TAKE THE ASSESSMENT
How we keep a custom agent accurate
No AI system is perfect, and any team that promises zero mistakes is selling you something. A serious build engineers the risk down four ways.
Grounding
The agent acts from your data and rules, not open-ended guessing. The biggest single lever on accuracy.
Scope limits
A tight agent that does one job well beats a broad one that improvises.
Human escalation
When the agent is unsure or hits something outside its lane, it does not fake an answer. It hands off to a person with the context.
Evaluation
We test against real cases before launch and keep checking after.
Why a done-for-you build beats the alternatives
A chatbot answers; an automation repeats a fixed rule until an exception breaks it. An agent reads context, decides, and acts inside the systems where the work happens. Use the simpler tools for fixed, answer-only tasks; use an agent when the work needs judgment.
Build-your-own-agent platforms hand you the tools and leave the build, grounding, integration, and upkeep to you. dotfun hands you a working agent instead of a toolkit and a to-do list.
Handing a spec offshore gets you code that runs but often does not understand your business. dotfun is the same senior team that runs growth and operations for our clients, so people who understand the funnel build the agent that plugs into it.
The parts teams worry about, handled
The workflows, the logic, and the data it runs on belong to your business, not to a platform you rent.
We do the integration work so the agent reads and writes inside your tools from day one.
The agent does what you scoped it to do and escalates the rest to a person, rather than improvising outside its bounds.
We maintain it, correct what drifts, and extend it as your workflow changes, so it keeps earning.
Iris or a custom agent — which one do you need?
dotfun builds both, so we can be honest about the split.
Iris is our productized AI growth platform — a ready-to-run system with an AI receptionist, voice, SMS, calendar, web chat, and an AI CRM you switch on. A custom agent is our bespoke work — built around your specific stack, data, and workflow, for a problem no packaged product covers.
Choose Iris when a proven front-desk and growth-automation system fits; choose a custom build when the work is specific to your business. Not sure which side you are on? The AI Audit diagnoses which path pays back before you commit.
Agent development sits in dotfun's AI Solutions wing, alongside AI software development and workflow automation — for when a job needs an app or process built, not an agent.
Built by dotfun.
the same senior engineers who run automation for dotfun's growth clients every day. They bring 30-plus combined years in B2B tech and software builds to your workflow.
And because that team sits next to our growth and design work, an agent ships wired to the funnel and the tracking, so the work it does shows up in pipeline — not just in a log. That is the edge our AI agent development services carry that a standalone dev shop cannot.
Frequently asked questions
A chatbot answers. An agent reasons over a goal and takes action: it works inside the tools you already run, decides what to do next, and finishes the job instead of handing it back to a person.
An agent is one autonomous worker with a goal. Workflow automation orchestrates a multi-step process across your stack. Plenty of builds use both, and we scope which one your problem actually needs before anything gets built.
A finished agent, built for you rather than handed to you. You are not buying a platform to learn and staff. We scope the job, build it against your real data and edge cases, and hand over something that runs.
Four ways: grounding it in your own data, setting hard scope limits on what it may do, routing anything uncertain to a person with the full context, and running an evaluation set it has to clear. No agent is perfect, and any team promising zero mistakes is selling you something. The work is engineering the risk down.
The repeat work that needs judgment but not a person: support and customer success queues, RevOps execution, and the cross-tool steps someone currently carries by hand. It is built for B2B operators whose workflow does not fit an off-the-shelf product.
If the problem is front-desk and speed-to-lead work, inbound calls, follow-up, leads that never get logged, Iris covers it and works on day one. Build custom when the workflow is specific to your business or spans your own tools. If that is still open, the free Iris by dotfun AI Maturity Assessment is a 15-minute way to settle it.
Who a custom AI agent is built for
Our AI agent development services fit teams with a specific, repetitive workflow a packaged product does not cover.
B2B operators with a workflow that does not fit a product
You have a process specific to how your business runs, and no off-the-shelf tool matches it. A custom agent is built around your workflow, not someone else's.
Support and CS teams drowning in repeat work
Your team spends the day on triage, routing, and first responses that follow a pattern. An agent takes that front layer so your people handle the cases that need judgment.
RevOps and growth teams who need clean, fast execution
You need leads qualified and routed, records kept clean, and follow-up that does not wait on someone remembering. An agent runs that layer so speed-to-lead stops depending on who is watching.
Founders who want it done, not DIY
You know an agent could take real work off the team, but you do not want to become an AI shop to get it. dotfun builds it and maintains it.
