For freelancers
Take on more accounts without working more hours.
It optimizes every account overnight, inside the guardrails you set — freeing hours for the clients you already have, or the next one you take on.
Take on more work, not more hours.
Every account you run gets a full optimization round each night, freeing hours for the clients you already have — or the next one.
You stay the one who decides.
Anything past the limit you set lands in Slack with the numbers and the reasoning, and waits for your yes.
A window for your client, not the keys.
Invite them into the workspace and limit them to their own account — nothing else in your workspace is theirs to see.
Built for the solo operator running someone else's money.
Every account gets the same guardrails and the same written reasoning your own judgment already runs on — so you can stand behind every call it makes.
What does STRMLINE take off your plate?
Every account you run gets one full optimization round a night — every campaign and ad set read, and budgets moved where the numbers support it. Between rounds, it watches for delivery, tracking and connection problems on everything you manage, all day, and messages you in Slack the moment one breaks.

You set the ROAS target and the weekly spend cap, and one guardrail: how big a budget move it may make on its own. Anything past that line arrives in Slack with the numbers and the reasoning behind it, and waits for your approval before anything changes. You can stand behind every call it makes, because you can see exactly why it made it.

What does your client actually see?
Invite your client into the workspace and limit them to their own ad account — teammates are free, so this costs nothing either way. They see the same decisions and the same reasoning you do, and nothing from any other account in your workspace. Nobody has to ask you what happened last night.

Five questions. Straight answers.
There's no hard cutoff, but at lower spend levels there's usually more noise in the numbers, which calls for fewer changes to get the best performance — so an account under roughly €5,000 a month won't get you as much time back as one that spends more. You'll see a heads-up when you connect an account that small, not a block.
Your combined spend across every connected account is checked every month. If it moves you into a different band, you get an email five days before renewal — accept it early, or let it apply automatically. If it settles back down first, nothing is charged.
Invite them into your workspace and limit them to their own account — teammates are free either way. They see the same decisions and reasoning you do on that account, and nothing from anything else in your workspace.
You connect through Meta's own login, and it asks for exactly three permissions: read campaigns and results, change budgets and turn campaigns or ad sets off, read your Business Manager's name. Two levers only — budget, and on or off. Watch it decide in shadow mode first, for as long as you want, before anything is real.
Full optimization from day one, in shadow mode or live — no card required, and you're not charged unless you start a subscription. If it ends first, optimization pauses but your workspace and history stay exactly as you left them.
