Our Role
Jane Hartwick has 20+ years turning design vision into production reality with international brands, scaling startups, and established niche labels.
Her foundation is technical design with an expertise in product systems.
Jane translates creative vision into structured production-ready documentation — and builds the development framework that support consistent growth.
Listening carefully.
Identifying structural gaps.
Implementing practical, repeatable solutions.
The result is not just better documentation. It’s a structured product system that frees you to lead strategically instead of managing preventable errors.
If you are…
expanding your size range
refining grading for greater fit consistency
preparing for larger production runs
moving through excessive or ineffectual sampling rounds
unsure whether your tech packs are truly production-ready
starting to feel strain in your product development systems
Let’s talk.
Our role is to help you clarify what needs adjustment — and what doesn’t — so your product development process becomes structured, predictable, and aligned with where your brand is headed next.
In our free consultation, we’ll review where friction is showing up and map a practical path forward.
