Prototyping that lets you test the experience, pressure the assumptions, and decide before you build.
Interactive prototypes at the right fidelity for the question, tested with the people who'll use the real thing.
The cheapest mistake is the one caught in a prototype. Temper And Forge helps you decide before you build.
Our Prototyping Process
01
Define the question to answer
Every prototype exists to answer a question: will users understand this flow, does this concept earn interest, is this interaction learnable. We define the question and the evidence that would settle it before choosing fidelity, because the question determines the build.
02
Build at the right fidelity
Paper-level clickthroughs answer structure questions; high-fidelity interactive prototypes answer behavior questions. We build the cheapest version that can produce a trustworthy answer, because prototype polish that doesn't serve the question is waste.
03
Testing with representative users
The prototype goes in front of people who match your real audience, with tasks instead of tours. We watch where they hesitate, what they expect, and what they miss, and we record it so the evidence outlives the session.
04
Findings and the build decision
You get the findings, the recording highlights, and a clear recommendation: build it, change it, or drop it. Either way the call gets made on evidence that cost days to produce instead of a launch that cost months.

Temper And Forge has designed and developed two WordPress websites for us and is currently developing a third. They integrated a shopping cart and class registration feature, and they demonstrated exceptional flexibility when we shifted priorities mid-project — adapting without missing a beat and consistently delivering work ahead of schedule. Temper And Forge introduced tools like Figma that became part of our ongoing workflow, and their close-knit leadership kept communication seamless throughout. We've seen an increase in our email sign-ups and website engagement, and the team has produced the best work for us.
