Turn solo streaming into a shared experience your users won’t quit
AiFi is a software-only SDK that syncs the phones, tablets, and speakers your users already own into one immersive surround-sound system that lifts retention, sparks viral growth, and opens a new revenue line. No hardware. Just a few lines of code.
Our first streaming partner grew 400% with AiFi · 2× average session length · Sub-millisecond sync
Publicly listed on Spotlight Stock Market · 6+ granted patents · Engineering immersive sound
AiFi Music
Turn solo listening into a social event. Users sync their phones into a 3D surround system, so every session becomes something they share, lowering churn and driving organic, built-in growth.
AiFi Video
Make the smartphone part of the home cinema. AiFi syncs TV audio with the mobile devices around it for true surround sound, a premium reason to stay subscribed, with no new hardware to buy
AiFi Commerce
Bridge the gap between the TV and the hand. Trigger real-time, scene-specific offers on the viewer’s phone, connected as a speaker, at the peak of engagement. Sell measurable click-Throughs instead of just impressions.
Streaming perfected the picture. Audio got left behind.
Platforms have spent a decade on 4K, HDR and adaptive bitrate. Sound still comes from whatever single speaker the viewer happens to sit near, and solo, passive viewing is the easiest thing in the world to walk away from. That is where churn comes from. AiFi closes the gap: it turns the devices already in the room into one shared, immersive sound system, and turns watching alone into watching together.
One SDK. Three ways it grows your platform:
Retention that compounds, Shared viewing keeps users in the session longer (partners see up to 2× average session length) and gives them a reason to come back. Sound becomes a feature people stay for.
Acquisition that pays for itself, Every time a user invites a friend to join the sound, that is an install you didn’t buy. AiFi turns word-of-mouth into a measurable channel and pulls your CAC down.
Revenue you don’t have today, With Scene Commerce, synced phones become a new, measurable monetisation surface — context-aware offers at peak engagement, with no extra ad load. Read more about how AIFI works.

Why platforms choose AiFi
Pure software economics: No hardware to manufacture or ship. AiFi scales instantly to the billions of devices already in users’ hands, zero logistics, zero unit cost.
Audio that markets itself: Most audio tech is a cost centre. Every “join” in AiFi is a social transaction that brings in a new user, so the feature funds its own growth.
Priced so you only pay for growth
AiFi runs on a Half-CAC model: you share your current customer acquisition cost, we halve it, and you pay that half-rate only for verified new installs AiFi drives, nothing upfront. The Growth Guarantee backs it: if AiFi users don’t generate at least 0.5 new users each within three months, we work for free until they do.
400%, the growth our first streaming partner saw with AiFi, by syncing just a few phones into a portable surround-sound system.
