As answered by people managing Project Euler and PATTERNISSE.
PATTERNISSE's answer:
PATTERNISSE puts many jobs in one place. Drop in a pattern and it tags itself, stores it in a neat online shelf, and shows it on a dress or wall right away. You can send big files with one link, see which designs a client opens, and add a pay-now button without leaving the page.
PATTERNISSE's answer:
Most designers jump between four or five apps. PATTERNISSE does the same work in one login, so you spend less money, lose fewer files, and close deals faster.
PATTERNISSE's answer:
Surface and pattern designers, wallpaper makers, textile teams, and licensing agents, anyone who works with repeating artwork and big image files.
PATTERNISSE's answer:
Our founders were pattern designers fed up with messy folders, printed look-books, and late payments. They built a small fix for themselves, friends wanted in, and PATTERNISSE grew from there.
PATTERNISSE's answer:
AWS keeps the files safe and scales as you grow. OpenAI add some AI magic. Stripe handles payments and invoicing. The site itself is written with Typescript, SQL and HTML.
PATTERNISSE's answer:
One of the five biggest wallpaper brands in Europe, multiple large U.S./Portuguese textile mill, and hundreds of indie pattern studios rely on PATTERNISSE every day (names under NDA).
