What custom AI development actually is

A model trained on your own data, not a thin wrapper over someone’s API

Most "AI development" rents a prompt on a hosted API: generic, leaking your data. Custom AI is trained on your data and owned by you.

Your data → your modelDatabaseDocs / PDFsCRM recordsYour dataFine-tune + RAGYour private model“Your refund policyis 7 days, sir.”Generic public LLMno link to your dataKnows nothingabout your businessTrained on your data. Owned by you, not rented.

Trained on your data

A model fine-tuned or built on your own history and documents, so it answers in your domain, not a generic one scraped off the web.

Deployed in your stack

Runs in your cloud or on your servers, inside your VPC, so customer data never leaves an environment you control.

Owned, not rented

The weights, the code and the pipeline are yours, so you are not held hostage to a per-call API price that moves without you.

What we build

The custom AI systems we train, fine-tune and ship

Not "do AI". The specific models and systems that earn their cost, each trained or tuned on your data.

Why a trained model beats a thin API wrapper

A model you own, or an API you rent

Most "AI development" rents a prompt on a hosted API: your data leaves on every call, you own nothing. A model trained on your data flips that.

Are you building a model, or renting a prompt?

A wrapper is the right call for a quick experiment. For anything that handles your customer data at volume, the economics and the law point the other way. We train the model on your data, deploy it in your stack, and hand you the weights, so the system gets better as your data grows and the cost stays under your control.

How we build AI in India

Built for what an Indian business can run and own

An AI build scoped for a US cloud bill does not survive an Indian P&L. We build to your data, your rupees, and the law.

  1. 01of 04
    Data residency is the lawDPDP Act 2023

    Sending customer data to a foreign API on every call is exactly what the DPDP Act now governs.

    We train and deploy on infrastructure you control, with consent, retention and processing kept inside India, so the model is compliant with the Digital Personal Data Protection Act before it scales, not retrofitted after a notice.

    Our methodTrained and served in India, designed to the DPDP Act.
  2. 02of 04
    Build vs API economicsCost at volume

    A per-call API is cheap at a thousand calls and brutal at a million.

    We model the crossover before we build: a hosted API like OpenAI or Anthropic against an open model you fine-tune and run yourself, on cost per call, latency and residency, so the unit economics hold at your real volume.

    Our methodBuild vs API crossover modelled on your real volume.
  3. 03of 04
    Your data decidesReadiness over ambition

    Most AI failures are data failures, not model failures.

    We audit what data you actually hold and how clean it is before promising an outcome, because a model trained on a thin, messy dataset is a demo, not a system that ships.

    Our methodData readiness checked before a model is scoped.
  4. 04of 04
    Multilingual realityHow India reads and writes

    Your customers write in Hindi, Marathi and Tamil, not just English.

    We fine-tune and test on Indian-language data, so document intelligence and support models read the scripts and code-switching your customers actually use, instead of failing on the first regional-language form.

    Our methodFine-tuned and tested on Indian-language data.

Why OpenAI

OpenAI’s models are the fastest route to a capable AI feature, the right default when training from scratch isn’t justified.

How we excel

We start most builds on OpenAI with prompting and fine-tuning, so a custom feature ships in weeks, and we only train bespoke models when the data demands it.

How the build runs

A custom AI build on a clear timeline, where a measured result lands before the production commitment.

01Weeks 1–3Planned

Check the data, then scope the model

We audit what data you hold and how clean it is, model the build-versus-API economics at your volume, and scope the model and target. You sign off before training starts.

Train on your data, prove it on a benchmark

We build the data pipeline, train or fine-tune the model on your data, and benchmark it against the target on real cases, so you judge the model on a number, not a demo.

Our commitment

Our commitment, in writing

Custom AI goes wrong when the model misses its target, when your data leaves your servers, or when the inference bill blindsides you. We commit against all three.

  • Benchmarked before deploy

    We train and measure the model against a target you set on real data before anyone signs off production. No benchmark, no deploy.

  • You own the weights

    The model weights, the code and the pipeline are in your accounts and your name. Leave us and the model still runs, with no API key holding it hostage.

  • Your data stays in India

    Trained and served on infrastructure you control, designed to the DPDP Act, never sent to a foreign API on every call.

  • Costs on the table

    Training and inference costs estimated up front, with the build-versus-API crossover modelled, so the unit economics are clear before you commit.

If the model does not hit the target, you do not deploy it.
