About
A Sri Lankan company building for the agent age.
Quadra Lanka is a registered Sri Lankan technology company. We build AI agents, online stores and business software, and we research how agents should behave before they are trusted with real work.
Why the name
Quadra means four.
Every project we take on sits in one of four practices: we build agents, help businesses sell, equip teams with tools, and think hard about where AI does and does not pay. The mark is those four squares, with one lit: the part of your business an agent takes on first.
We are engineers who have run live payment, commerce and finance systems in Sri Lanka. That background shapes how we build agents: with approvals, logs and a named person answering for every step that matters.
How we build agents
Four rules we do not bend.
A person signs off
Anything that moves money, reaches a customer or cannot be undone waits for a named person.
Every step is logged
You can see what the agent read, what it decided and why, long after the fact.
Plain about cost
You see the build cost and the running cost before anything starts, including the model bills.
Your data stays yours
Your accounts, your keys, and model settings that do not train on your data.
Where we work
From Colombo, for anywhere.
We work with Sri Lankan businesses in person and with companies abroad remotely. Local knowledge matters for the details that break software here: payment gateways, courier networks, Sinhala and Tamil, and the way approvals really move through a company.
We keep the team small and senior. You talk to the people who design and build your system, not to an account manager.
