Ostium

Growth Marketing

• Own user acquisition end-to-end and unlock new channels.
• Strategize where our next 10k traders come from — and execute the experiments to prove it.
• Start as a hands-on operator running campaigns and growth experiments alongside our Head of Marketing, creative, social, and BD team.
• Identify, test, and scale acquisition channels we aren't running today — SEO, lifecycle/email, paid social, TikTok, YouTube creators and finance influencers, Reddit, Telegram communities, podcast sponsorships, referral and affiliate programs, retargeting, regional channels in LATAM/SEA/MENA, and whatever asymmetric tactic you spot before anyone else does.
• Build a CFD/trader-focused creator program — sourcing, negotiating, briefing, measuring.
• Stand up the SEO motion from scratch: keyword strategy, programmatic pages, comparison and "vs" content, education hubs, and link-building.
• Own the email/push/in-app journey from waitlist to first deposit to retention — segmentation, triggers, win-back, deposit flows.
• Stand up paid channels where regulation and CAC allow — programmatic, paid social, search, native — and kill what doesn't work fast.
• Define the metrics, build the dashboards, and run a relentless experimentation cadence: CAC by channel, funded conversion rate, LTV, payback period.
