What we build
Pick one, or combine a few. Most projects mix two or three of these.
-
Mobile apps
Native iOS and Android apps, or one cross-platform codebase. We handle the App Store and Google Play release too.
Ask about mobile apps -
Web development
Fast, accessible websites and web apps, from a landing page to a full platform with accounts and payments.
Ask about websites -
SaaS products and MVPs
Turn an idea into software people can sign up for and pay for, with billing, teams and admin tools.
Ask about SaaS -
AI and automation
RAG, fine-tuning, agents and document extraction, tested on your real data. See our AI work.
Ask about AI -
Healthtech
Software for clinics, care providers and health startups, built privacy-first with sensitive data kept to a minimum.

Fintech
Payments, ledgers, invoicing and statement tools, with a clear record of where every number came from.

Cloud and DevOps
Hosting, automatic deploys, monitoring and backups, so releases are routine and nothing lives on one laptop.

App rescue and maintenance
Inherited a broken or half-finished app? We review the code, fix what matters first and keep it up to date.

AI that works on your own data
We build AI and LLM features that answer from your documents, follow your rules and keep working after launch. Every system ships with tests, so you can see how accurate it is before your customers do.
Question: How many days do customers have to return an item?
Answer: Customers can return an item within 30 days of delivery, as long as it is unused and in its original packaging.

- Index your documents
- Find the right passages
- Write the answer
- Check it and cite sources
-
Search and chat over your documents
Retrieval-augmented generation (RAG) that answers from your files and knowledge base, and shows the source for every answer.
-
Fine-tuning
Train an open model on your own examples, so it uses your terms and follows your rules. A small tuned model can also cost less to run.
-
AI agents and workflows
Assistants that use your tools and APIs to finish real tasks, with a person approving the steps that matter.
-
Document data extraction
Turn PDFs, scans, forms and bank statements into clean, structured data your systems can use.
-
Testing and guardrails
Test sets that measure accuracy before and after every change, and checks that keep answers safe and on topic.
-
Private and on-device AI
Models on your own servers or on the phone itself, so sensitive data stays under your control.
-
Voice and speech
Speech-to-text, transcription and natural voices for apps, meeting notes and customer support.
-
The right model for the job
OpenAI, Anthropic or open models such as Llama, Qwen and Gemma, chosen for quality, speed, privacy and cost.

Questions people ask
Can’t find your answer? Send us a message and we will reply within two working days.
Ask a questionHow long does a project take?
A simple website takes one to three weeks. A first version of an app or SaaS product usually takes two to four months. You get a timeline in the written plan before any work starts.
How much does it cost?
It depends on the scope. After the first call we send a fixed quote, or a monthly rate for ongoing work. The first call and the quote are free.
What do I need to get started?
An idea and a few minutes. Tell us what you want to build and who it is for. Designs, documents or an existing app help, but you do not need them.
Can you work on an existing app or codebase?
Yes. We often take over apps from other developers. We start with a short code review, then fix the most important problems first.
Is my data safe if you build AI features?
Yes. Your data goes to an AI provider only if you agree, and we choose providers that do not train on it. For sensitive work we can run models on your own servers or devices.
Will you sign an NDA?
Yes. We are happy to sign your NDA before you share any details.
Who owns the code?
You do. When the work is paid for, the code, designs and accounts are yours.
How do we work together day to day?
Remotely, at times that suit your time zone. You get a short update every week and a preview link you can try at any time.
What happens after launch?
We can keep your product updated, watch for problems and add features on a monthly plan. Or we hand everything over to your own team, with notes.
