One source of truth for everyone you work with
Millstream is the shared workspace where your team, your clients, and the studios you collaborate with all work from the same projects, files, and conversations. Everyone finally sees the same picture.

“Two customers couldn’t pay this morning.” Flagged as urgent on your call, repro steps attached.
You pushed to checkout-flow from 9:14 to 11:46, which matches the NovaByte project.
The signed-off proposal went to Sarah yesterday at 16:02, so the deal stage looks stale.
One home for the tools that keep your studio turning
The problem
Everyone's working from a different copy
Briefs sit in email. Feedback is split across DMs and comment threads. Clients ask for updates you've already sent. The freelancer you brought in can't see the latest files. Each tool does its job, but the work keeps moving between people, and the context falls into the gaps.
So work gets done twice, approvals slip, and the team ends up milling around trying to figure out what's current.
Built for collaboration
One source of truth, shared with everyone
Bring the three circles you work with into one place and keep everyone looking at the same thing.
Your team, in sync
Everyone works from the same projects, tasks, files, and discussions. Nobody has to chase the latest version or post the same update in three places.
Clients in the loop
Invite clients to review work, follow the board, and raise requests. They see exactly what you choose to share, and you skip the status emails.
The studios you collaborate with
Work alongside the freelancers and studios you partner with in shared project spaces, without handing over your whole workspace.
What's inside
Every tool your studio touches in a week
Built to work together, so context flows with the work instead of getting lost between apps.
Projects & Kanban
Organize work by client, capture tasks as tickets, and drag them across the board from brief to done.
Time tracking
A timer that lives in the sidebar, with client and project rates so your logged hours turn straight into revenue.
Media review
Upload images, video, and PDFs, then collect feedback as comments right on the asset.
Discussions
Realtime chat on every workspace, project, file, and ticket, with desktop notifications so nothing slips by.
CRM
Companies, contacts, and a timeline of every call, meeting, and email in one place.
Documents
Rich documents that live with the client or project they belong to, not in a drive nobody checks.
Social planning
Draft, approve, and schedule posts across platforms, with assets pulled straight from your media library.
Trips & mileage
Log routes with location autocomplete and per-kilometer rates, so travel time makes it onto the invoice.
Plus a live activity feed, a ⌘K command palette, granular permissions, multi-workspace support, and a dark mode.
Who it's for
Built for studios that juggle clients
If your week is a mix of client work, deadlines, and billable hours, Millstream was made for you.
Creative studios
Design, photo, video, and content studios that run several clients at once and want files, feedback, and hours in one place.
Agencies & teams
Small agencies that want projects, approvals, time, and client access under one roof instead of a pile of subscriptions.
Solo & freelance
Independents who want a professional home for client work, with a private personal workspace alongside it.

Why we built it
Made by a studio, for studios
Millstream started as the tool we wished we had. We were running client work across a project board, a time tracker, a shared drive, a CRM spreadsheet, and three chat apps, and we kept losing time in the seams. So we built one place that holds all of it. It's the system we use to run our own studio every day, and we're opening it up to a small group of teams who feel the same pain.

FAQ
Questions, answered
Everything you might want to know before requesting access.
What exactly is Millstream?
A shared workspace that gives your studio one source of truth for client work. It puts your team, your clients, and the studios you collaborate with in the same place, where projects, a Kanban board, time and trip tracking, media review, notes, a CRM, discussions, and social planning all live together. Everyone works from the same picture instead of a dozen scattered tools.
Who is it for?
Studios, agencies, and service teams that manage client work, from solo freelancers to teams of around fifty. If you bill for your time and juggle multiple clients, it will feel like home.
It's in closed beta. What does that mean?
We onboard a small number of teams at a time so we can support each one properly and shape the product around real use. Request access and we'll reach out as spots open up.
How much does it cost?
Beta access is free while we build alongside our first teams. We'll announce pricing well before anyone is charged.
Can my clients use it too?
Yes. Invite clients as external members to review media, follow the board, and raise requests, while your internal tools, rates, and CRM stay private.
Is my data safe?
Your data is isolated per workspace with database-level access controls, hosted in the EU. You can request deletion at any time.
Which languages are supported?
Millstream is fully available in English and Dutch, and you can switch whenever you like.
Do I need to install anything?
No. Millstream runs in your browser, with a dark mode and a ⌘K command palette to move fast.
