Joynt Co-Ownership Platform

Joynt is a seed-stage PropTech startup helping friends and family co-buy and co-own a home together, handling the legal structure, financing, scheduling, and day-to-day decisions in one place. I own the end-to-end experience, from a prospective co-buyer's first visit through onboarding and into long-term co-ownership, designing the high-stakes legal and financial steps to feel clear and human. I also use Cursor to build and ship much of that work myself, cutting typical prototype-to-shipped timelines from one to two weeks down to one to four days.

The Problem

Housing affordability is pushing more people to buy with friends or family instead of alone, but there's no good system for doing it well. Groups struggle just to get moving, coordinating over scattered texts and group chats with no shared place to track progress, then run into the same unanswered questions about agents, lenders, and legal structure. Many skip the legal structure entirely just to close, which leaves them exposed. After move-in, the risk doesn't go away, it just changes shape: friendships strain, there's no plan for someone who wants out or can't pay anymore, and big decisions get argued out, or avoided, in a group text.

The Users

Joynt serves two groups at different stages of the same journey. Prospective co-buyers span every generation, from Gen Z pooling with roommates to Gen X parents buying alongside their adult kids, all trying to figure out if co-ownership is realistic for their specific group before they commit to anything. Existing co-owners are largely the same people, years further in: friends, relatives, and multigenerational families now living with the decision, managing a shared budget, calendar, and votes, most without much financial or legal sophistication.

The Solution

For prospective co-buyers, I built Joynt Lite, a free planning hub with guided checklists, alignment surveys, and property-fit tools that help a group get aligned before they spend real money on an agent or attorney. I designed the onboarding and legal flows, signup, co-owner invites, MFA, to make high-stakes steps feel approachable instead of intimidating. For existing co-owners, I redesigned the core ownership surfaces, group home, budget, calendar, voting, statements, and chat, for mobile and accessibility with an updated visual system.

The Impact

Joynt is a small, seed-stage team, so speed mattered as much as the design itself. Using Cursor to implement my own designs directly in production cut typical prototype-to-shipped-UI timelines from one to two weeks down to one to four days, without ever handing the build off to engineering. That speed let the team ship a complete journey, education, planning, and management, rather than a single thin feature, and sets up fast iteration once real usage data starts coming in from the marketing efforts now underway.
