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 understands how elite traders operate and knows how to win them over. The market we’re going after moves trillions. We’re not a b2b SaaS startup selling software licenses. We’re earning trust with traders moving 50M one clip Nasdaq shorts.

This role is about turning existing product-market fit into volume that compounds. You’ll own acquisition from outreach to onboarding to expansion, helping us scale from early traction to capturing significant market share.

It’s not about “growth hacks” - it’s about building strong relationships that convert into volume, spotting opportunities first and fast.

What you’ll be doing

Expand our whale trading base

• Own relationships with high-volume traders in Telegram/Discord

• Track activity daily to identify outreach opportunities and follow up at the right time

• Use onchain data to identify and convert whales from other platforms

• Help active users scale order size and explore new markets on Ostium

Run acquisition motions that actually work

• Reactivate churned users and pull traders from CEXs into onchain markets

• Launch incentives that resonate with crypto-native traders

• Build credibility with CT influencers and the protocols that matter

You should probably

• Know DeFi trading deeply - perps, leverage, liquidity, execution

• Have 2-5+ years in crypto sales, BD, account growth, or trading-related roles

• Understand how traders evaluate counterparty trust and execution quality

• Have a track record of bringing in meaningful business

• Move fast without losing the plot

• Be data-aware but not data-stalled - you know when speed matters
  

You definitely have

• Experience managing high-value relationships (ideally whales or funds)

• Comfort with onchain data tools (e.g., Hyperliquid explorer, Arkham,

• Nansen)

• A repeatable follow-up process - traders remember who shows up

• Clear written and verbal communication - especially in DMs

• Strong ownership - you close what you start
  

Bonus points if you have

• A network among high-volume traders, CT influencers, or crypto funds

• Experience in APAC trading markets (Japan, Korea, SEA)

• Exposure to market making, execution systems, or structured trading groups

• Previously taken traders from CEX → onchain perps or exotic markets

• Competed in trading events or run trading communities yourself
