The problem

Modern life is quietly killing your relationship.

Phones. Late nights. Endless scrolling. Nobody woke up this morning planning to drift apart. But without intention, that's exactly what happens. Fuse is the thing that fights back.

We didn't build Fuse because relationships are broken.

We built it because the world stopped making space for them. And someone had to.

How it works

Four steps. One stronger bond.

01

You check in. Takes 60 seconds.

Tell Fuse how you're feeling. Your mood, energy, and how connected you feel today. Fuso — your companion — remembers everything.

02

Your partner checks in separately.

They don't see your answers. You don't see theirs. Not yet. This is intentional — honest answers first, comparison later.

03

Your AI companion reveals the patterns.

Fuso compares your check-ins and surfaces what it sees — alignment, tension, what's changed. Not therapy. Better than that.

04

Streaks, insights, games, and The Room.

Track your relationship health over time. Play games that spark real conversation. And when things get tense, step into The Room.

Features

The Room gets its own moment

Daily check-in

Know how they're really doing — before you even ask.

The daily check-in takes 60 seconds and covers your mood, energy level, and connection pulse. Fuso — your bear companion — synthesises both of your responses and shows you where you align, where you don't, and what changed since yesterday.

  • Takes 60 seconds
  • Both partners answer independently
  • Fuso compares and reveals patterns

The Room

A calmer place to go when things heat up.

When something feels off, The Room gives you both a space to cool down before the conversation goes somewhere you can't come back from. Sage — an AI mediator — guides the session. No sides. No blame. Just clarity.

  • 2-minute cooldown before you enter
  • Sage reads both sides simultaneously
  • Private reflection before shared reveal
Couples who use structured cool-down reduce argument escalation by 67% — Gottman Institute.

Fuso

A companion that knows you both — and never takes sides.

Fuso isn't a bot. It's your relationship's memory. Every check-in, every journal entry, every conflict you resolve — Fuso tracks the arc of your relationship and surfaces insights you'd never notice yourself.

  • Weekly relationship summary
  • Personalized to your love languages & attachment styles
  • Crisis detection with immediate resources
💡 Did you know? Couples who reflect on positive interactions daily report 34% higher relationship satisfaction. Fuso prompts this automatically.

Activities

Connection shouldn't feel like homework.

Fuse has 30+ activities built for couples — multiplayer games you play in real time, quizzes that reveal how well you actually know each other, and daily dares that are simple but surprisingly powerful.

Today's dare: Send one unexpected compliment before bed.

The science

Built on research, not vibes.

Every Fuse feature traces back to peer-reviewed relationship science. Here's the foundation.

The 5:1 Ratio

Dr. John Gottman's 40-year study of 40,000+ couples found one number predicts relationship success with 94% accuracy: five positive interactions for every negative one. Fuse's check-ins are calibrated to help you hit this ratio without thinking about it.

Attachment Styles

Pioneered by John Bowlby and expanded by Sue Johnson's Emotionally Focused Therapy, attachment science shows that most relationship conflict is rooted in unmet attachment needs — not the fight you're actually having. Fuse maps your attachment styles and helps you decode the real need underneath the argument.

The Power of Daily Rituals

Research from James Clear and habit science shows that identity-level change comes from showing up consistently, even briefly. Checking in with your partner for 60 seconds daily doesn't just feel good — it literally rewires how your brain patterns attachment over time.

Early reactions

People are already talking.

Honestly I came for the check-ins but stayed for The Room. We had a fight last Tuesday and instead of the usual spiral, we both just opened the app. 20 minutes later we were laughing. I don't know how it works but it works.

It's like having a relationship coach in your pocket that isn't judgy or expensive.

★★★★★
My partner was skeptical. The first time Fuso reflected back that we were both stressed and disconnected at the same time — without either of us saying it to each other — he went quiet for a second and said 'okay, this is actually something.'
Priya & Daniel — Together 5 years — London
★★★★★
The daily dare feature sounds cheesy. It isn't. We've been doing it for two weeks and it's become our favourite 3 minutes of the day.
Alex K. — Melbourne
★★★★★
I've tried Paired and Lasting. Fuse is the first one that actually feels like it was built for our specific relationship, not couples in general.
Emma & Jack — Together 2 years — Auckland
★★★★★
We had our biggest fight of the year two weeks ago. We used The Room. Sage helped us both say things we'd been sitting on for months. I literally cried. In a good way. The Bridge Summary at the end — the reveal of what the other person actually needed — changed something.

From the founder

Elias, 18

Sydney, NSW · Sole founder, Cutler Labs Pty Ltd

I'm 18 years old. I built Fuse alone, during Year 12, because I watched people I love — including my own family — slowly stop investing in each other.

Not from a lack of love. From a lack of tools.

Every self-improvement category has incredible apps. Fitness. Finance. Sleep. Meditation. But when it comes to the most important relationship in most people's lives, the best couples have is... hope and good intentions.

That felt wrong to me.

So I built Fuse. Because I genuinely believe that if couples had the right tools — something designed specifically for two people, not one — the outcomes would be different.

I'm not a relationship therapist. I'm a builder who cares. The science is real. The team will come. Right now it's just me, this app, and the belief that your relationship deserves better than surviving the week.

Thank you for being early. I won't waste the trust.

Frequently asked

Questions answered.

We're in the final stages of development. Early access members will be the first to know — expect launch in 2026. Everyone on the waitlist gets notified the moment we go live.
The first 500 couples who join the waitlist will receive our lowest price tier — locked in for as long as they use Fuse, regardless of future price increases. It's our way of saying thank you for believing in us early.
Yes — Fuse is built for two. You invite your partner with a unique link. They create their own account, and you're connected. The magic happens when you're both checked in.
100%. Your check-in responses and journal entries are encrypted and never shared — not even between you and your partner, unless you choose to share them. We use Supabase with row-level security. We will never sell your data.
Paired is a great app for conversation prompts and quizzes. Fuse goes further — we offer real-time analysis of both partners, a dedicated conflict resolution tool called The Room, relationship health tracking, and a smart companion that learns your specific relationship patterns over time. It's the difference between a playlist and a music teacher.
Absolutely not. Fuse is like going to the gym — it's for couples who want to stay strong, not just couples who are injured. The best time to use Fuse is when things are already good and you want to keep them that way.
Yes. Solo mode lets you use the check-in, journal, and Fuso AI features independently. If your partner joins later, they can connect to your existing account and see the relationship arc from the beginning.
Individual plan from $9.99/month. Couples plan from $10.83/month (annual, = $129.99/year). Founding members lock in a special rate. Full pricing revealed at launch.
The Room is Fuse's conflict resolution feature. When something feels off, both partners enter a structured space guided by Sage — an AI mediator. It's not couples therapy, but it uses the same core principles: cool down first, reflect second, reconnect third. The Bridge Summary at the end reveals what each person actually needed.
Fuse is built by Elias, 18, sole founder of Cutler Labs Pty Ltd (ABN 15 697 138 159), under Australian consumer law. The app uses Supabase for data security and smart personalisation features, and is built with the same care I'd want in any product I use with someone I love. I'm not hiding behind a corporate front. You can DM me directly at @joinfuseapp.
