The Buildsheet
Built for enthusiasts.
An SFC product built end-to-end using our own process — from strategy and brand through to a live production app — in three weeks.
The Product
The Buildsheet is a community platform where car enthusiasts document, share, and discover modified cars. Catalog modifications, track services, upload photos, and publish a living build log that evolves with your project. Viewing and following builds is free forever — subscribe to publish your own.
Community & Admin
A community feed for members to explore and follow other builds, and a lightweight admin dashboard for tracking growth, engagement, and flagged content.
Why We Built It
Today, the way enthusiasts share their builds is scattered across forums, Instagram, and spreadsheets. None of it captures a car's story in one place. The Buildsheet is that place — a structured, social record of how a build comes together, over years and thousands of miles.
Built Using SFC's Process
From zero to a live product in three weeks — start to finish — using the same process we bring to clients.
01
Product Strategy
Scope, user flows, and feature prioritization defined up front. We decided what to ship and — just as importantly — what to leave out.
02
Brand Development
Name, voice, visual identity, and the marketing surface, all produced using SFC's Brand Development Process.
03
AI-Guided Build
MVP built with Determined Agency Design — authentication, subscriptions, image uploads, and a production deploy — in days, not months.
