Bespoke AI,
built for your team.
Koso is a custom AI development agency. We design, engineer and ship bespoke AI agents, copilots and AI operating systems for teams who refuse to settle for off-the-shelf software.
What we build
Custom AI,
end to end.
One senior team covering strategy, design, engineering and operation. No handoffs to partners you've never met. Everything we ship is production-grade software your team can own.
Custom AI agents
Bespoke agents that own an outcome - qualify leads, draft replies, chase invoices, monitor ops. Not chatbots. Software that ships work.
In-app AI copilots
Embedded copilots for your product. Streaming, citations, tool calls, evals - production-grade from day one.
AI Operating Systems
One coordinating brain above your CRM, sheets, inbox and docs. Workflows, memory, agents and reporting wired together.
Autonomous workflows
Cross-tool processes rebuilt as AI-native flows. Less context switching, fewer manual handoffs, real time back to your team.
Why "best"
Custom AI that
actually behaves like software.

How your custom AI gets built.
Four phases, one team. Discover and Design take two weeks each. Build lands in production in weeks, not quarters. Operate stays as long as you want us there.
Discover
Two weeks inside your business. We shadow the work, map the tools and find the ten places AI moves a real number.
Design
A written blueprint - modules, data flows, integrations, guardrails, cost model. You sign it off before we write code.
Build
Two-week ship cycles. Everything lands in production and in your team's daily use. No demo environments.
Operate
We run it with you. Tune prompts, watch cost, catch drift, add capabilities as your business and the models keep moving.
Where we work
A custom AI development team,
wherever your business runs.
Koso partners with teams across India, the US, UK and Australia. Async by default, on-site when it moves the work faster. Time zones stop being an excuse when the AI is shipping while you sleep.
Trust
A dev team that actually ships AI.
120+ AI products shipped
Across ops, sales, support, product, education and content.
Production-grade by default
Evals, observability, guardrails and cost controls on every build.
Bespoke, never templated
No agent farms. Every system is scoped to your workflows and data.
Questions
Before you ask.
Why call Koso a custom AI development agency?+
Because everything we ship is scoped to your business. No templated agents resold across clients, no wrappers on top of one prompt. We architect, build and operate custom AI - agents, copilots and systems - the same way a great product team would.
Who do you typically work with?+
Growth-stage companies, enterprises and ambitious founders across India, the US, UK and Australia. Ops, sales, support and product teams that want a real AI moat instead of another SaaS subscription.
What does a project usually cost?+
Scoped by modules and complexity. Most builds land between a mid-market SaaS renewal and a senior engineering hire, with clear line items per module. Full proposal within 48 hours of the first call.
Do we own what you build?+
Yes. You own the code, the prompts, the infra config and the data model. If you ever want to take it fully in-house, we hand it over clean.
How is this different from a generic AI consultancy?+
Consultancies write decks. We ship software. Strategy, engineering and operation live under one roof, so there is nothing to hand off to a partner you have never met.
