Tools for the people
who make homes happen

We build practical software for contractors, designers, and homebuyers.

A family business, built close to the work

Three tools.
One common thread.

Every product we build starts with a real person doing real work. We resolve the friction that complicates their job.

For Contractors

Rafter

Field documents, fast

Rafter generates professional bids, proposals, safety documents, and field paperwork, typically in less than 30 seconds. Built for self-employed contractors and tradespeople who don't have time or patience for a desk job.

For Designers

Vellum

Studio docs, polished

Vellum gives interior designers, decorators, and landscape designers a fast, beautiful way to generate proposals, letters of agreement, invoices, change orders, and all the paperwork a solo studio runs on.

For Homebuyers

TakeHome

Clarity across showings

TakeHome is a fun, low-pressure tool that helps homebuyers track the properties they're considering, compare what matters, and feel more confident at every step, from first tour to final offer.

Small team.
Specific focus.

Field Assembly LLC is a family business based in Massachusetts. We write software for the parts of work that most tools overlook: the paperwork, the decisions, and the details that keep a project on track.

Our products don't try to be everything. Each one is built around a specific person with a specific problem, and designed to feel like it was made with them in mind, not for a generic market.

We ship quietly, build carefully, and stay close to the people who use what we make.

"We built the first one because someone in the family needed it. The rest followed because enough strangers did too."
