GTM

Ostium is on a simple mission: make it possible for anyone with a digital wallet to trade stocks, commodities, currencies, and crypto with full transparency. No brokers, no freezes, no hidden spreads. We’re replacing the opaque, offshore brokerage model with a transparent, permissionless trading stack built onchain. Every trade, deposit, and withdrawal is verifiable through open, auditable code. We’ve raised $27.9M+ from General Catalyst, Jump, LocalGlobe, Susquehanna (SIG), GSR, Alliance DAO, Soma Capital, Balaji Srinivasan, Meltem Demirors, and others.

About the role

We need someone who can shape how traders feel about onchain markets - in real time.

You understand that crypto trading isn’t just numbers on a screen - it’s adrenaline, conviction, macro narratives, and people placing big bets based on what’s happening right now. You know how to take that energy and turn it into content that moves volume.

You don’t wait for stories - you catch them the moment they emerge. A whale switches to Ostium? A major macro move hits? A new asset pair opens? You’re already drafting the post. You get why traders deposit, why they hesitate, and what pushes them over the edge.

This role is less “social calendar management” and more high-velocity market storytelling that keeps Ostium at the center of the conversation.

We’re scaling fast: from $500M to $27B+ in onchain volume since March

What you’ll actually be doing

Turn market moments into momentum

  • When the Fed speaks, crypto dumps, or oil spikes - you’re first to create content pertaining to why it matters for traders

Tell the story the leaderboard can’t

  • Highlight trader wins, strategies, new assets, and volume surges in a way that builds trust and FOMO

Ship daily - with taste

  • High-quality posts that are timely, confident, and aligned with Ostium’s brand tone

React within minutes, not hours

  • You operate on trader time - a few minutes max between event and post

Make complexity feel tradable

  • Help users see how our products unlock real opportunities in global markets

Live where traders live

  • Actively engage in Discord, Telegram, CT - spotting signals and sparking conversation

Collaborate across GTM

  • Work with product, design, and growth to amplify launches, new listings, and campaigns

Track what actually drives volume

  • Analyze post performance with Dune, X analytics, internal dashboards - and double down on winners

Your work will push answers and content to support questions like:

  • “Why are whales rotating into commodities right now?”

  • “How did that trader 3× their account overnight?”

  • “What’s the edge of trading FX onchain vs IBKR?”

You’re probably

  • Obsessed with markets - you follow macro and crypto news like sports

  • A quick and clean writer - clarity, confidence, no meme-speak needed to be funny

  • A storyteller at heart - you see a chart and instantly think “What’s the narrative?”

  • Community-driven - you enjoy talking with traders and don’t shy from spicy replies

  • Strategic about hype - you know what earns trust vs. cheap engagement

  • Comfortable with imperfect info - you post fast and refine faster

You definitely have

  • Experience running social for a trading, crypto, fintech, or fast-moving product

  • Strong understanding of DeFi, leverage, and how traders choose where to deposit

  • Proof you’ve grown accounts or content that reached real scale

  • Ability to self-produce short-form visuals and videos with polish

  • Comfort tracking social media metrics and optimizing based on performance

  • Availability to operate on ET/APAC hours and jump on urgent moments as they break

Bonus points if you

  • Have been part of crypto trading communities or creator networks

  • Know your way around on-chain data tools (ex. Dune, Arkham, Nansen)

  • Can sniff out whales or alpha unlocks before they’re public

  • Have run campaigns or content that led directly to measurable growth (revenue, volume, deposits)

  • Understand CFDs, FX markets, or TradFi brokerage dynamics

Real talk

  • This is a hands-on role - you write, produce, post, reply

  • Speed matters - markets move, and we move with them

  • You’ll be the voice of Ostium to traders watching the charts right now

  • Success isn’t impressions - it’s volume
