Investor overview

The hands-free layer for every call on the road

Sllo keeps music playing when the phone rings, announces the caller and answers by voice — with all AI on the device. Pre-launch on Android, proven on real hardware, built to run with no backend.

Thesis

Why Sllo

The problem is daily and universal

Every incoming call cuts the user’s audio and pulls their eyes and hands to the screen — driving, cycling, cooking, working with gloves on. Phones still treat media and calls as competitors.

The product works today

Not a prototype video. Ducking, restore, caller announcement and voice answer are confirmed on a real Android 16 flagship with real cellular and WhatsApp calls.

The economics are unusual

All speech recognition runs on the phone. No servers means near-zero cost to serve each subscriber at $4.99/month or $49.99/year, and nothing to breach.

The moat is the integration

Sllo sits on Android’s telephony, audio-focus and notification layers and answers third-party call apps through their own buttons. Getting that right across devices is slow, unglamorous work that compounds.
