Are you ready to build something real that could shape the PropTech industry? We’re launching the PropStack Project, a PropTech coding challenge where developers compete to create a live, interactive tech stack manager — inspired by StackShare.io — but designed for the real estate vertical.
This competition focuses on Multifamily (“Apartments” or “Flats”) as the first asset class, with scope to expand across the PropTech ecosystem.
Build a full-stack web application that visually maps out the technology companies used in the Multifamily real estate industry. Think of it like StackShare.io, but specifically designed for real estate asset classes.
- A dynamic dropdown system:
- Multifamily → Node (e.g., Occupancy) → Sub-Category (e.g., Move In) → Tag (e.g., Tenant Tech Package)
- Display company cards (logo + name + link) for each selected sub-category
- Collapse all unrelated paths when one tag is selected
- Back-end support for editing and expanding the tech list (can be no-code or custom CMS)
- Clean, intuitive UX inspired by StackShare.io
- Color palette to be taken from PTAG
💰 First Place: $500 USD + featured on our developer platform
Top participants may be invited to join our developer pool for client-facing work
- Full-stack web application (frontend + backend)
- Clean, modular code
- Intuitive UI with collapsible navigation
- Backend must support adding/editing tech stacks
- Bonus points for:
- Clean design
- Efficient data handling
- CMS integration
Here's the updated JSON file used in this project:
assets/PropStack_MF_Updated_Structure_Links.json
This file now contains:
- The complete
Multifamily → Area → Segment → Sub-categoryhierarchy - A list of companies under each sub-category with:
nameurllogo(currently a placeholder)
- Navigational references like
"See CRMs"are now formatted as:{ "see": "CRMs" }
To participate, please submit:
- A link to your GitHub repo
- A live demo (or screen recording)
- A short explanation (in
READMEor video):- Your structure and approach
- How to run it locally
- Any special tools or frameworks used
📩 Submit your project here: Submit via Google Form
- Launch Date: 25th March 2025
- Submission Deadline: **Monday, 31st March 2025
- Winner Announced: TBD
We’re inspired by platforms like StackShare.io that organize tools by category and use case.
Here’s an example of the experience we're reimagining for real estate:
