Services
AI agents for WhatsApp, web chat and your own tools.
We build AI agents that answer customers, take orders and bookings, qualify leads and hand the conversation to a person when they should. Each agent works from your catalog, prices and policies, and passes its evals before it talks to a customer.
When it fits
- Your team answers the same questions on WhatsApp all day.
- Leads write at night and wait until morning for a reply.
- Orders and bookings arrive by chat and get retyped into another system.
- The answers have to come from your own catalog and policies.
What you get
- The agent, with tools wired to your systems
- Retrieval over your documents and catalog
- An eval suite that runs in CI on every change
- Fallbacks between models and providers
- A console to review conversations and hand-offs
How we build it
How we work- 01
Map the job
We read real conversations and write down what the agent handles, what it never does and when it hands off to a person.
- 02
Wire it to your data
Tools for your catalog, calendar or CRM, and retrieval over your documents, so every answer has a source.
- 03
Write the evals
Graded test cases from your conversations, with a pass threshold. They run in CI on every change, and again when the model or the prompt changes.
- 04
Pilot and watch
A first group of real customers, a console to review conversations and hand-offs, and a second provider that takes over if the main model is down.

Engagement
Engagements and pricingFAQ
Which channels can the agent work on?
WhatsApp, through Meta's official WhatsApp Cloud API, and a chat widget on your website. Other channels are scoped per project.
What happens when the agent doesn't know the answer?
It is built to answer only from your data and to hand the conversation to a person, with the context, when it can't. The evals test exactly those cases.
How do you know it's good enough?
Before launch it has to pass a set of graded cases taken from your real conversations. The set runs on every change, and the agent stays off until it meets the threshold we agree with you.
Which AI models do you use?
Claude, from Anthropic, by default. A second provider takes over when the first one fails, so a model outage doesn't stop your customers.
What does an AI agent cost?
The AI Agent engagement starts from $8,000, and the proposal fixes the price of each milestone. Model usage and WhatsApp messaging fees are billed by those providers to your own accounts.

Guides
All guidesGuide 08 · 3 min A build log, explained: how AI agents and an engineer ship a pull request.
The home page of this site replays a pull request: spec, plan, changes, tests, deploy. This guide walks through that pull request, the one that added AI triage of new leads, and what a person did at each step while agents wrote the code.
Guide 06 · 2 min AI agent or chatbot on WhatsApp: which one your business needs.
A chatbot follows a menu someone wrote. An AI agent reads what the customer wrote and looks up the answer. Both run on WhatsApp, both have a place, and the right one depends on what your customers ask.
Guide 05 · 3 min How we test an AI agent before it talks to a customer.
A demo shows the answers someone picked. Evals are graded test cases with a pass threshold, and an agent stays off until it meets it. This is how we write them, with the evals behind this site's own lead triage as the example.
Guide 02 · 4 min How to build a WhatsApp AI agent for your business, step by step.
These are the four steps we follow to build an AI agent on WhatsApp, with what Meta's platform asks for at each one. It's written for the person who decides whether to build one, with enough detail for the engineer who will.
Guide 01 · 4 min How much does an AI agent cost? Prices from a studio that builds them.
Building an AI agent with us starts from $8,000, at a fixed price per milestone. Running it costs model usage and channel fees, billed by those providers to your own accounts. This guide explains what moves both, and what to ask any team before you hire them.
