FinnTech is a one-principal software studio in New Plymouth. Finn Greig scopes, builds and hands over web apps, automation and AI integration for startups, SMBs, enterprise and government, bringing in collaborators per project rather than an account manager.
Web apps, product interfaces and sites, designed and built front to back. Modern TypeScript stacks by default, your existing stack when that is the right call.
Integrations, data pipelines and scheduled jobs that take manual work off your team: the plumbing between the systems you already run.
Language models wired into real products and workflows: extraction, classification, drafting, search. Scoped to what a model does reliably, not what a demo promises.
A live land-listings widget pulling current sections into a Queenstown architecture firm's Squarespace site, so the listings page stays current without anyone editing it. flexihouse.co.nz
A B2B marketplace connecting automation providers with manufacturers, launched end to end on a self-hosted Sharetribe frontend: role-based listing visibility for the two sides, and the default Stripe flow removed to fit a paid-listing model. theautomationbrokers.com
A pre-owned luxury watch retailer importing stock from a Japanese wholesale feed into Shopify. Traced silently failing product images to a third-party image host, then fixed inventory sync with a daily reconciliation pass and repaired order fulfilment end to end. timelessluxury.co.nz
A short written scope before any work starts: what we are building, what it costs, what done looks like.
Working software early and often. You see progress in a real environment, not a slide deck.
Source, documentation and access are yours. No lock-in, and no retainer needed to keep the lights on.
You talk to Finn throughout. Collaborators join per project when the work needs them. There is no account manager.
A few lines about what you are building, or what is stuck, is enough. Finn replies personally, in New Zealand hours.
