Day 1

Evals & observability

## AI products,  
not AI demos.

Real applications with auth, billing, guardrails and observability - the boring parts that decide whether an AI product survives its second month. We ship those on day one.

Copilots

### In-app AI copilots

Embedded copilots that turn your product's complexity into a conversation. Streaming, tool calls, citations, guardrails - production from day one.

Vertical SaaS

### Vertical AI SaaS

New product lines built on AI from day one. We co-build with your team or ship as a dedicated squad, all the way to first paying customers.

RAG

### RAG & knowledge systems

Production RAG over your docs, tickets and databases. Evaluated, monitored, versioned. Not a notebook experiment your engineers can't rebuild.

Agentic apps

### Agentic products

Multi-step AI agents wrapped as real applications - onboarding flows, dashboards, permissions, billing. Software users pay for, not demos.

## One team.  
Every layer of the product.

Product thinkers, designers and AI engineers on the same Slack channel. No handoffs, no rewrite between the "AI part" and the "app part" - it's all one product.

/01

### Product & UX

Product strategy, UX for AI, prompt design, evaluation frameworks - so the product feels right, not just works.

/02

### Engineering

TypeScript, Python, Next.js, TanStack Start, FastAPI. Clean, typed, testable code your team can own on day one.

/03

### AI infrastructure

Model routing, vector search, memory, caching, streaming, tool calls, observability, cost controls.

/04

### Cloud & ops

Vercel, Cloudflare, AWS, GCP. Deployments, CI/CD, monitoring and on-call for the first 90 days.

## From idea to shipped product

This is the inbound sales agent we built for a US B2B SaaS company, written up the way it happened. Yours won't go exactly like this, but the shape is usually close.

1. Wk 1  
Sat in on their inbound queue for three days. Demo requests landed in a shared inbox and waited about four hours for a reply, mostly because the SDRs were researching every lead by hand before writing back.
2. Wk 2  
Cut the scope to inbound demo requests. Partner enquiries and support questions come through the same form, and those stayed with people.
3. Wk 3–4  
Nothing shipped. We pulled a few hundred old leads out of HubSpot and had their best SDR mark the ones worth chasing. That became the test the agent had to pass.
4. Wk 5  
First version live, with a human in front of it. The agent qualified the lead and drafted the reply, and an SDR approved every email before it went out.
5. Wk 7  
Turned on booking, so qualified leads could pick a slot on a rep's HubSpot calendar straight from the first email.
6. Wk 9  
Median time to first reply was 6 minutes, down from 4 hours. We still run it with them.

## AI product development,  
that actually reaches production.

## Before you ask.

What kinds of AI products has Koso built?+

In-app copilots for B2B SaaS, vertical AI SaaS from zero, RAG-powered support and research tools, agentic ops platforms, content and creative studios, and internal AI products for large enterprises.

Do we own everything you build?+

Yes. You own the code, the prompts, the infra config and the data model. If you ever want to take the product fully in-house, we hand it over clean, documented and covered by tests.

How is Koso different from a typical dev shop?+

Most dev shops learned AI last year. Koso has shipped 120+ AI products, and the same team owns product, design, AI engineering and ops. Nothing gets translated across a language barrier of Jira tickets.

Can you take a product from idea all the way to launch?+

Yes. Discovery, prototype, MVP, launch, and the first 90 days of iteration. We can also embed with an existing product team if you already have engineers and just need AI horsepower.

Where are your clients based?+

India, the United States, the United Kingdom and Australia, with async delivery by default and on-site sprints when it moves the work faster.

## Let's build your AI product.

Bring us the idea, the roadmap or the half-shipped prototype. We'll come back in 48 hours with a scoped plan - phases, timeline and cost - to get it into your users' hands.
