No Hype Driven

Every technology decision is checked against four questions.

01

Fit

Does it solve your problem better than the alternatives?

02

Longevity

Will it be maintained and hireable for five years or more?

03

Cost

What does it cost to run, scale and staff over time?

04

Ownership

Can your team understand and take it over without us?

Our architects review existing stacks and recommend a path forward, whether that means modernise, migrate or leave it alone.
