Breaking Solitude: Designing Connection on Campus
How I created a digital safe space for 500,000+ college students across the United States so that they could discover more events, expand their circles, and feel less alone.

When a campus full of events still feels empty.
Students had events everywhere but zero visibility and zero belonging.
Students coexist but feel isolated when events are invisible.
Most campus events stay hidden inside exclusive circles, leaving new students feeling isolated even when campus is active.
Sixty five percent of students report loneliness. Hosts need safety and control, while guests need visibility and belonging.
44%
of students report symptoms of depression (Healthy Minds Study, 2022).
65%
of college students report feeling lonely (Active Minds, 2024)
“Loneliness is a clear factor in the well‑being of college students”
— Alison Malmon, (Active Minds)
Most campus events are invisible unless you're already inside the right circles.
WHY THIS MATTERS
No visibility unless you’re personally invited
Not open to the public
No way to request access
Why hosts restrict access: safety, liability, and campus discipline:
The Tension
Hosts need safety
Guests want transparency
Understanding how belonging breaks down on campus
Research and AI synthesis revealed a clear mismatch. Students discovered events socially, while the app showed none of that.
INTERVIEW INSIGHTS
Event Invisibility
Events felt hidden unless someone shared them.
“I always find out about events only after they happen.”
Social Gatekeeping
Access stayed locked inside certain groups.
“If you're not in Greek life, you're out of the loop.”
Discovery Happens Socially
Students discovered events socially, not through apps.
“Group chats are the only way I know about events.”
Host Safety Concerns
Hosts restricted access for liability.
“If someone gets hurt, it’s on me.”
I grouped 120 interview notes into four clusters using AI-assisted grouping in Cursor and manual synthesis in FigJam.
Affinity Map: The four themes that shaped the product direction
From interviews, I identified two opposing needs. Hosts prioritized safety and control. Guests sought visibility and belonging. This tension became the core design challenge.
Turning insights into product direction
Research showed the real issue was invisibility. Students needed visibility. Hosts needed safety. The product supported neither side.
PROBLEM STATEMENT
Students relied on friends and group chats to discover events, but the app showed none of that. Hosts needed tight safety controls. Guests needed visibility and belonging. DoorList supported neither side, creating confusion, loneliness, and hidden events.
GOAL 1
Enable early discovery
Let students see events before they're full or forgotten
GOAL 2
Surface social context
Show who else is going and how events connect to friends
GOAL 3
Preserve host control
Give hosts tools to manage visibility and guest lists safely
Learning from apps students already trust: I analyzed apps students use daily to understand real discovery behavior and mental models they already rely on.
Friends influence decisions. I used this mental model to design “friends going” and social-first event visibility.
Students check where friends are. This pattern inspired friend-centered discovery instead of a public feed.
Relevance drives engagement. I used this pattern to inform personalized suggestions powered by social signals.
Designing openness without breaking trust
Doorlist only works if hosts trust it with safety and every step toward visibility risked losing that trust.
Opening discovery risked breaking host trust
The assumption was simple: visibility would drive attendance.
Discovery failed, but demand surfaced
There were almost no public events. Hosts did not share.
Still, students kept tapping Discover.
12x more taps than any other tab
Public visibility felt unsafe
Making events public increased risk. Trust was fragile.
“If We Open Discovery, Admins Will Drop Off.”
Social proximity felt earned
Public feeds felt risky; friends felt safe. So I reframed discovery around people, not events.

Public Events Only
Your Friends' Events
Added a friends row for immediate access to your circle’s events.
Seeing your friends’ events made the feed feel personal, not public.
Refining Discovery Until Friendship Became the Core Experience
Every redesign centered more around friends — until connection wasn’t just a feature, it was the foundation of DoorList.

Making the feed the heartbeat of social connection
By making the home feed central, Doorlist became the place to check events, not just manage them. Users with 5+ friends were 4× more likely to return, proving that curiosity and connection made the app sticky.
The Final Iteration
Live
Providing value in the feed, even when you’re not invited
Before, uninvited users couldn’t see private events, or later, could only see them with no way to act. By opening events to requests, users gained a path to signal interest, preview friends attending, and stay engaged — while hosts retained total control.
Guests earned agency by requesting +1s, fueling organic app growth
Before:
❌ No way to request +1s: Guests depended entirely on admins.
❌ Exclusive barrier: Only close to the host or group = access.
❌ Friction: No organic way for friends to join together.
Now:
Moved the +1 button into a primary CTA — which led to a 3× increase in guest requests.
Turning safety into trust with clear +1 and attendance controls
Admins could now approve or revoke +1s, see exactly who joined the list, and track entries with time-stamped attendance — clear proof their needs were at the center of every design decision.
Turning Doorlist into the college connection hub
By shifting the app from utility to social loops, I created stickiness that drove growth and retention. When I started, Doorlist had 45,000 users and poor retention. Today, it has over 500,000 users, with projections to reach a million next year.
4x
Higher retention for users with 3+ friends, proving social connection drove stickiness.
40%
More successful invites; smart suggestions removed the need to search or type.
3.4x
Lift in 7-day retention by adding friend visibility and a personalized feed users actually cared about.
6x
User growth by turning invite flows into a peer-to-peer growth machine
REFLECTIONS
This project taught me that safety and connection don’t have to conflict. By designing with empathy, I learned how structure and openness can coexist — how giving admins control can actually make students feel more free to connect. Doorlist showed me that design can protect people while still helping them find each other. It reminded me that thoughtful boundaries don’t limit connection; they make it possible.
