What we do

What our generative AI development covers

Copilots and assistants

In-app assistants that draft, summarise, answer and take actions for your staff or customers, grounded in your own data.

Content generation

Product descriptions, marketing copy, reports and emails generated in your brand voice, with review steps before anything is published.

Image and media generation

Product imagery, design variations and visual assets generated from prompts or templates, built into your existing workflow.

Document generation

Proposals, contracts, summaries and structured reports drafted from your templates and records, ready for human sign-off.

Fine-tuning

Models fine-tuned on your examples when prompting and retrieval are not enough, with evaluation to prove the gain.

Private LLMs

Open-source models such as Llama, Mistral or Qwen hosted on your own cloud, so sensitive data never leaves your environment.

In depth

How we approach Generative AI development

Prompting, retrieval or fine-tuning

Most GenAI products work best with good prompts plus retrieval from your own documents. We only recommend fine-tuning when you have enough quality examples and a clear gap that retrieval cannot close, because it adds training and maintenance cost.

Choosing the right model

We compare GPT, Claude, Gemini and open-source models on your real tasks for quality, speed and cost before committing. The architecture keeps the model swappable, so you can switch providers as prices and capabilities change.

Guardrails and review

Generated output goes through checks for format, tone, facts against your sources and sensitive content. Where accuracy matters, we add a human approval step and keep a log of every generation.

Private by design

We use API providers configured not to train on your data, or host open-source models on your own cloud. For healthcare work, our HIPAA-trained team builds to HIPAA requirements.

Working with us from Tokyo

Remote, but close to Tokyo

Time-zone overlap

Japan is three and a half hours ahead of India, so our working days overlap for most of your afternoon, with a stand-up and same-day replies.

Japan's Act on the Protection of Personal Information (APPI)

We design to the APPI: clear purpose of use, security controls, rules for third-party and cross-border transfers, and data hosted in Japanese cloud regions when required. We sign NDAs before work starts.

Billing

Invoices in Japanese yen (JPY) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.

Weeks 2-3: build and integrate

Senior engineers build in short sprints, connect your systems and demo working software every week.

Week 4: test and launch

We test with real data, set up monitoring and deploy to your own cloud account, then go live.

After launch: support and grow

The same team stays on for support, improvements and new features, with guaranteed response times.
