Brooklyn, NYC

Built bymusic makers

Sinewav was born from frustration. We were tired of getting fire emojis when we needed real feedback.

"I just need someone to tell me if this drop works. Not 'fire emoji.' Not 'sounds good.' Actually useful feedback."

Every producer
at some point
The Problem

Generic feedback everywhere

Posting to forums and getting buried. Group chats where feedback meant a thumbs up. Platforms optimizing for streams, not craft.

The Spark

A Brooklyn apartment

Surrounded by synths and drum machines, a group of producers debated the same problem for the hundredth time. "Why is this so hard?"

The Decision

Build it ourselves

No existing platform focused on feedback. They all wanted to be the next Spotify. We wanted something different.

Today

Sinewav is live

Waveform feedback, version control, threaded discussions—every feature we wished existed. Built by creators, for creators.

Our mission is simple

Help music creators release their best work with confidence.

What we believe

Creator-First

Every feature starts with: does this help creators make better music?

Quality Over Quantity

One thoughtful critique is worth a thousand fire emojis.

Community-Driven

Your feedback shapes our roadmap. Your needs drive development.

Always Improving

Iterating, learning, and getting better every single day.

Our Home

Made in Brooklyn

From underground clubs to bedroom producers making waves worldwide, Brooklyn understands that great art comes from community, experimentation, and honest feedback. That spirit is in our DNA.
