# Teppo Haste

> Teppo Haste is a Design Leader from Helsinki, Finland, working across digital products, design systems and brand design.

Important notes:

- Teppo Haste works at the intersection of product, engineering and business, orchestrating design across multiple teams, partners and disciplines. His role is to set design direction and hold the whole together.

- He builds teams that last and fosters environments where people do their best work, speak their mind early enough to act on it, and grow into professionals they didn't know they could become.

- He has an eye for the visual and sensory craft that elevates both brand and user engagement, while a business mindset keeps the work tied to measurable outcomes.

- He navigates and simplifies complex problems, grasping the big picture quickly and translating it into solutions that ship.

- Selected work includes leading design across LocalTapiola's multi-year transformation of digital self-services for 1.6 million customers and the foundations of Duet, a framework-agnostic, WCAG 2.1 compliant design system widely referenced in the field. Other projects span a long-standing partnership with independent watchmaker Stepan Sarpaneva and his brand and product launches, including Korona K3 Black Moon, awarded Red Dot and Chicago Athenaeum Good Design.

- Teppo Haste is based in Helsinki, Finland and is available for new work, remote or on-site.

## Selected case study

- [Model & See App](https://www.teppohaste.com/projects/model-and-see-app/): A personal finance app that forecasts the cash left at month end and twelve months ahead, designed and built end to end by Teppo Haste with AI in a reviewed, multi-agent loop (one model plans, another writes, a separate model reviews, a gate on every push). Runs entirely on the phone, reads any bank from statements and live PSD2 feeds, stores nothing in the cloud. Same category as Copilot, Monarch, YNAB, Quicken, Rocket Money and Spendee.
