What you can read before you apply
Some creators like to talk first and see numbers later. Others – often the more cautious ones – want to know the basics before they share anything about themselves. Neither approach is wrong, but it helps to know which one an agency follows.
According to SirenCY's application page, fees come in a proposal, and its about page says contract terms are provided separately and should be reviewed before you commit. That is sensible advice for any agency.
At Murmur, the essentials are public: 25–50% of revenue after the platform fee, which applies to everything your page earns after OnlyFans' 20%, including existing revenue. No upfront fees, no extra fees, monthly cancellation. Your exact rate and scope are then agreed in writing before we start. For a discreet creator, knowing this much before sending an enquiry can make the first step much easier. Our journal guide to OnlyFans agency fees explains the calculation step by step.
From enquiry to a real answer
SirenCY says it aims to review complete applications within two business days. We reply personally to every enquiry within 12 hours. Speed is not proof of quality, of course – what matters is that the reply is specific to you and not a template.
When you send an enquiry anywhere, notice the tone of the answer. Does it ask about your boundaries and your time, or only about your numbers? That first message often shows how the rest of the relationship will feel.
Two ways of showing results
According to SirenCY's homepage, it presents visual transformations and creator profiles rather than individual revenue statements. We speak about our team's overall track record: experience since 2021, more than 30 creators managed and over $10M in creator revenue (USD).
Neither format predicts your own results. Whatever an agency shows you, ask about the starting point, the period and what has already been deducted. And be wary of anyone who turns another creator's story into a promise for you – we don't make income promises at all.
Give the weekly rhythm a purpose
Both agencies describe weekly work on your page. The value of that rhythm lies in the decisions it leads to. In your weekly review at Murmur, your manager goes through what went live, what sold, what fans asked in chat and how your social channels did – and you agree together on one or two next steps.
Whichever agency you choose, ask: what will I decide in our weekly conversation, and what will you decide without me? Our free weekly review template shows what a useful review can contain.
Check who you are signing with
SirenCY publishes its company details on its about page, including its company name, an ABN and an Australian address. That kind of transparency is good practice. With any agency, make sure your written agreement names the contracting company and its address, states your rate and the revenue it applies to, and explains how access and payouts are handled.
