Mixrounds is the client studio and back-office for freelance mix and mastering engineers — the review, the rounds, the contract and the invoice, in one link. Built by a designer who spent a decade shipping alongside mix engineers, and got tired of watching them run their studios out of eight tabs.
Every freelance mix engineer I know runs the same toolchain: Dropbox for the files, email for the notes, Notes.app for the round count, a Google Doc for the “contract”, PayPal or a Stripe payment link for the money, and a spreadsheet somewhere for the clients. Then a Loom for the walkthrough. Then a Calendly for the intake call. Then a group chat that becomes the source of truth when you least expect it.
None of those tools know about each other. None of them know what a revision round is. None of them stop the client, mid-round-four, from asking for “just one more small change”. The tools we borrowed from tech, design and consulting were never built for a job that ships in versions, gets reviewed against a waveform, and lives or dies on how disciplined you are about scope.
So the loop nobody productized is the one that matters most: the revision round.You send a version, they respond, you deliver, they respond again, and somewhere in there the meter should be running. In practice, it isn't — because there is no meter. Mixrounds is that meter, plus the boring back-office glue around it, in one place.
Hey — I'm David. I've spent over ten years as a senior product designer working across UX/UI and front-end, most of it inside the music industry rather than adjacent to it.
At Anglo Management I built and ran websites and digital campaigns for artists including Fatboy Slim, Pete Tong, Madness, Idris Elba and Roger Sanchez, plus festivals and labels like BMG and Universal Music. That gave me a front-row seat to how the industry's digital plumbing actually works — and where it doesn't.
Building those campaigns, I kept meeting the same person on the other end of the email: the engineer. The one delivering the mix, chasing the notes, absorbing the fourth round for free, and invoicing three weeks late because the admin was somebody else's job and that somebody was them. Every artist site I shipped had a budget and a project manager. The engineer who made the record had Dropbox and a Google Doc.
Mixrounds comes from a simple belief: the people making the records shouldn't have the worst tooling in the chain. Mixing is a craft that ships in versions, gets reviewed against a waveform, and lives or dies on scope discipline — so it deserves software that understands a revision round, not eight tabs that don't know each other exist.
I spent years helping artists and labels build their presence online. This is me building the thing that helps the engineers behind them get paid properly for it.
No team, no advisor deck, no roadmap slide. One person writing the product, the contracts, the invoicing, and this page. If you email support, you email me.
