Jumbo
Head of Design·iOS·Acquired by Coalition
Jumbo is a privacy assistant for your phone. It connects to the apps you already use, like Facebook, Google, Twitter or Alexa, and helps you take back control: tighten your privacy settings, clean up old posts and recordings, and get alerted when something needs your attention. Everything runs on your iPhone, not on Jumbo's servers.
Here is how the product evolved, version by version.
V.alpha
A single app for all your privacy needs.
Connect your accounts, clean what you don't need anymore, and keep a private archive of the rest.
Onboarding
Smart privacy
Apps
Twitter cleaner
Memories
V.beta
Show what happens behind the scenes.
People needed to see what Jumbo was changing on their behalf, and why it mattered. We borrowed a mental model everyone already knows, antivirus software, and focused on getting every user to connect at least one service.
Alerts, actions and cards
One setup per service
V1
Start from what needs your attention.
Asking people to configure everything upfront wasn't helping them decide, and activation stayed low. So we flipped it: Jumbo audits your accounts first, then explains each threat in plain words, one screen at a time.
Audits and threats
Explaining a threat
Activation > 75%

FOMO
Co-founder, product and design·iOS·Live on the App Store
FOMO is tech news as a game, for founders, AI engineers and VCs who never want to be the last to know.
It comes in two modes. All day long, every big story becomes a quick quiz you answer on your own time. And once a week, everyone meets at the same time for a live game show hosted by SCOOP, our pixel anchor.
Mode 1 · News as it breaks
Answer the news before everyone else.
When a big story drops, a push notification goes out and a new quiz unlocks in the feed. One question, four answers, 15 seconds. Answer while the news is still fresh for a live bonus. Then comes the reveal: the right answer, how everyone else voted, and the full story to read. Points add up with streaks, accuracy and friends, and a weekly league leaderboard keeps the competition going.
Answer a question
Read the stories you unlocked
Mode 2 · The live show
A live game show, once a week.
Everyone joins at the same time. SCOOP hosts from the FOMO TV studio, questions arrive one by one with 15 seconds to answer, and the winners split the prize. For now the show runs about once a week; the exact cadence is still being tuned.
FOMO TV
Step inside the studio.
A miniature live TV studio built in Three.js: SCOOP at the anchor desk, the control room, the audience. Switch cameras, or pick Free camera and fly around with the mouse and WASD / arrow keys.
Behind the scenes
An editorial agent, with a human in the loop.
Every two hours, an agent reads the latest tech news and drafts question candidates. Each one is approved or rejected from Telegram before it goes live and the push goes out.
Social
Every question becomes a carousel.
Boussole
Product and design·iOS·Emotion Studio·Private beta·getboussole.com
Boussole is an AI-native reading companion. Save anything (links, notes, screenshots, voice notes) and Boussole reads it with your projects in mind. Every morning, it tells you what actually matters to you, and why.
Saving is easy; making sense of what you saved is not. The bet: the lasting asset isn't the content you save, it's a living model of what you care about.
The app
Wake up to clarity.
The daily brief
Good morning.
Every morning, Boussole connects what you saved to what you're working on: a few short reads, each with the reason it matters to you, and the sources one tap away.
Onboarding
Getting to know you.
Boussole is only as good as its picture of you, so onboarding is about context: a name, what you're working on, then two ways to go deeper.
Connect Boussole to Claude: a custom connector, set up in five guided steps
Then Claude writes your profile from what it already knows about you
The website
getboussole.com
A calm, scroll-driven story: capture without friction, let Boussole connect the dots, search your curiosity, and get refocused every morning.
Cappuccino.fm
Co-founder, product and design·iOS & Android·Backed by a16z. Scaled to 90,000 DAU and 500,000 total downloads.
Cappuccino is a daily audio show made by your friends. During the day, everyone records short voice stories. Every morning at 8, your Cappuccino is ready: a private podcast with the voices of the people you care about.
Here is how the product evolved, from the private alpha to the redesign.
V0 · 2019
The daily personal audio show featuring your friends.
All the alpha users were preselected from a waiting list, and their accounts were created manually from the admin panel. To log in, they only had to enter their 6-digit invite code. Then: one group, one record button, and a new episode every morning.
Onboarding
Listen, record, meet your crew
Every morning at 8
V1
Open to everyone, with profiles and groups.
No more accounts created by hand. New users now created their own profile: phone number, first name and a selfie. They could start a group, invite their friends with a code, and belong to several groups at once, each with its own daily episode.
Create your profile
Start a group, invite your friends
V2
Kickstart conversations.
All your groups on the home screen, prompts to get everyone talking, and a richer player.
Tell your stories
Record, preview, send
Redesign
Redesigning the recording and listening experience.
Hear the voices of your friends
Barista, the internal tool behind each episode

SUSH
Co-founder, product and design (CPO)·iOS & Android·Emotion Studio·Backed by a16z and Lightspeed. Scaled to 4.3M DAU and 17M total downloads.
SUSH is a virtual pet you raise with a friend. Two people adopt a little sushi together, take care of it every day, chat, and play games side by side. Their SUSH evolves as they look after it, and it notices when they don't.
