Sevthirteen
SYDNEY - MARKETING CLARITY FOR FOUNDERS
Everyone can make marketing now.
Almost no one can tell you what's right.
More tools won't fix your marketing. A filter will.
You've got AI, templates, and endless advice telling you what to post next. What you don't have is someone who'll tell you what to ignore. Sevthirteen works with founders who are capable, busy, and done guessing which of it actually matters. We bring the judgment, the plan, and the hands to run it, so you stop doing a bit of everything and start doing the few things that move your business.
Working with Nyrie at Sevthirteen has been an absolute game-changer for me and my business. From the very beginning, she took the time to truly understand not just what I do, but who I am and the vision behind my work.
Nyrie crafted a branded marketing strategy for me that was truly aligned, authentic, and powerful. She was collaborative, supportive, and energising at every step, bringing fresh ideas, insight, and knowledge to the world of marketing, and made what I felt was overwhelming feel simple and achievable.
The result is a clear, grounded marketing plan that reflects my voice, connects with my audience, and gives me confidence moving forward. I can honestly say Nyrie helped me turn my brand into something I’m proud to share with the world.
I highly recommend Sevthirteen to anyone ready to elevate their brand with heart, strategy, and impact.

Marketing has never been easier to produce
& harder to trust.
Every founder has access to the same tools now.
What you don't have access to is fifteen years of knowing which moves actually work and which just look good. That's what Sevthirteen brings. Not another tool. The judgment to use the ones you've got properly.
Nyrie Sereti
15+ years of judgment, built inside real businesses. Sydney-based marketing strategist Nyrie Sereti brings a strategic, hands-on approach to every engagement, at a time when anyone can produce marketing but almost no one can tell you which of it is actually right.
Her work starts with the real business objective behind the brief, not just what needs to look better, but what needs to perform better. She asks the questions most briefs skip, and tells you plainly what to stop doing, not just what to add.
Nyrie finds the gap between where you are and where you want to be, and brings the judgment to close it, not another list of options.
SERVICES
Every engagement starts the same way, cutting through what doesn't matter so we can focus on what does.
Not sure where your marketing stands?
We'll run a marketing audit for you.
​
Got a specific problem to solve?
We'll work on a strategy sprint for you.
01 | Marketing Audit
​
A scored, structured review of your marketing across six core areas: brand, messaging, website, content, social, and SEO. You receive a designed PDF report within 7 days with clear observations, priority flags, and a ranked action plan. An honest, outside view of where your marketing stands before you spend another dollar.
02 | Strategy Sprint​
​
A focused engagement built around one specific marketing challenge. You bring the problem. We define the scope, do the thinking, and deliver something actionable within 10 business days. No retainer. No open-ended brief. Just clear direction when you need it.
03 | Partnership​
​
An ongoing engagement for founders who want a standing filter on their marketing, not another vendor to manage. Each month starts with a strategy session and a clear priority plan, the few things actually worth doing next, not a scattered to-do list. From there, we get hands-on at the strategic layer: content direction, campaign structure, key copy, the work that sets the tone for everything else. You'll have capped access between sessions for time-sensitive calls, plus a deeper quarterly review to catch drift before it becomes a problem. Day-to-day posting and paid ad management sit outside this, that's for your own team or a specialist to run, this is the judgment that tells them what to run. 6 or 12 month term.
