Services

Software built for your business, by the team that builds ours.

We take on a small number of client projects: AI agents, apps, SaaS products and websites. You work directly with the engineers who build it, and the code is yours once it's paid for.

What we build

AI agents and automation

Support replies drafted from your help docs, documents read and posted into your systems, reports assembled overnight. Each agent is tested on your own cases before it goes live, and it stops for a person before anything that matters.

  • Support ticket triage and drafted replies
  • Invoices, contracts and forms read into your tools
  • Scheduled reports and alerts

Web apps, mobile apps and SaaS

Web and mobile apps, SaaS platforms, internal tools and APIs, with the cloud setup, monitoring and handover documentation to run them. We use plain code where AI doesn't help.

  • SaaS products and customer portals
  • Internal tools and dashboards
  • APIs, integrations and cloud setup

Websites and marketing sites

Business websites built for speed and search, with structured data for Google and AI assistants, and a lead pipeline so no enquiry is lost. Moves from an old site keep your existing search rankings.

  • Company and product websites
  • Lead capture, alerts and a simple CRM
  • Site moves that keep rankings

AI search and AI features

Search that answers from your docs, tickets and code and shows where each answer came from, or an AI feature built into your existing product. Every answer is scored against a test set made from your real questions.

  • Search over your documents and wiki
  • Answers in Slack that cite sources
  • AI features inside your product

How a project runs

Each step ends with something you keep, and you can stop after any of them.

  1. Step 1

    Scope

    1 to 2 weeks

    We map the work, measure how it runs today, and hand you a written plan, the architecture and a fixed quote. They're yours whether or not you go ahead.

  2. Step 2

    Prove

    3 to 6 weeks

    A working first version on your real data, checked against how the work is done today.

  3. Step 3

    Build

    Quoted after Prove

    Integrations, safeguards and review steps, shipped in pieces you can use along the way.

  4. Step 4

    Run

    Monthly

    Monitoring, updates and fixes after launch, so the system keeps working as things change.

You own what we build. Once each stage is paid for, the code, prompts, tests and documentation we write for you are assigned to you in writing. Indian clients get GST invoices.

Client work

Website, lead pipeline and analytics

Sarish Advertising

A print and branding business of over a decade moved off an old jQuery template onto a new brand and domain, without losing search visibility, with one place to catch and follow up every enquiry.

Rebuilt on a modern stack
Next.js and React, server-rendered, with a page per service and permanent redirects so existing rankings carried over.
No lost enquiries
Every enquiry is saved first, then emailed to the team, and the system records whether each alert was delivered.
Lead pipeline
A private admin to move each lead from new to contacted, quoted, won or lost, with notes and spreadsheet export.
Where leads come from
Whether visits came from search, social, AI assistants or direct, and which pages a person read before enquiring.
