Written requirements, screen specifications and acceptance criteria agreed before development.
Thorough testing
Automated and manual testing with reports at every milestone.
Reliable schedules
Realistic plans, regular written progress reports and early warning of any risk.
Long-term partnership
The same team maintains and improves the product after launch.
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.
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.
How we work with Japan clients
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.
Where we help Japan businesses most
Japanese companies value careful specifications, quality and reliable schedules. We work with detailed written specs, thorough testing and regular reports, and design to Japan's APPI privacy law.
Automotive
Carmakers invest in connected-car software and factory automation. We start with one costly process and automate it end to end.
Electronics and robotics
Hardware makers need companion apps and embedded AI. We build AI agents, assistants and automation around these workflows.
Gaming and anime
Entertainment firms reach global fans through apps and stores. AI here usually means faster reporting, fewer manual steps and better customer replies.
Retail and convenience
Chains run loyalty apps and cashless checkout. We start with one costly process and automate it end to end.

Which currency do you bill in, and what does it cost?+
We bill in Japanese yen (JPY) or US dollars. Senior engineers typically cost $25 to $49 (USD) per hour, and fixed-scope projects such as an MVP in 25 to 30 days are quoted after a free consultation.

Can you build in Japanese and English?+
Yes. We build interfaces and content in Japanese and English, and test them with native speakers before launch.
How long does it take to build a GenAI app?+
A focused generative AI product for one use case typically goes live in 25 to 30 days. Fine-tuning or private model hosting can add time, which we agree in the scope.
Do we need to fine-tune a model?+
Usually not at first. Prompting with retrieval from your documents covers most needs. We recommend fine-tuning only when testing shows a clear benefit.
