About the role

Posted Jul 24, 2026

At Improbable, we build and scale ambitious AI and Web3 ventures shaping the next generation of the internet.

We’re hiring for a venture building a next-generation blockchain for real-time, large-scale applications. Designed to overcome the speed and cost limitations of traditional blockchain infrastructure, the technology is fast, cost-efficient and fully EVM-compatible, enabling developers, creators and communities to build immersive products with greater ownership and interoperability.

The ecosystem includes a first-party DEX, a prediction markets protocol and several upcoming products.

About the role

We are looking for a Head of Marketing to turn this technology and product portfolio into adoption, volume and a recognised market position.

This is the venture’s most senior marketing role. You will report to the CEO, join the leadership team and own marketing across the Layer 1 and the products built on it.

You will build a product-led marketing engine that can repeatedly take technical products to market, acquire users and turn launches into sustained growth.

This is a player-coach role. You will set the strategy, build and lead the team, and remain close enough to the work to sharpen positioning, challenge campaigns and lead important launches yourself.

What you'll be doing

  • Own the marketing and growth strategy: Set the priorities, targets and operating model across the Layer 1, first-party DEX, prediction markets protocol and future products.

  • Drive product adoption: Build measurable acquisition, activation and retention programmes for traders, developers, partners and the wider Web3 market.

  • Lead positioning and launches: Define the venture’s narrative and create clear positioning and go-to-market plans for each product.

  • Build a high-performing function: Shape the team, establish clear accountability and keep internal and external specialists focused on product and commercial outcomes.

What we are looking for

You are a product and growth-focused marketing leader who has worked successfully across both Web2 financial products and Web3.

You understand the structured, data-led approach to marketing found in fintech or traditional finance. You have also applied that experience within a Web3 environment such as a DeFi, DEX, Layer 1 or Layer 2.

  • Senior marketing leadership experience across both Web2 and Web3

  • End-to-end ownership of positioning, go-to-market and growth

  • Evidence of increasing users, trading volume, revenue or market share

  • A strong understanding of acquisition, activation and retention

  • Experience leading teams while remaining hands-on

  • The ability to use data to prioritise decisions and measure results

If you have built and scaled marketing across both Web2 financial products and Web3, and want to shape how a next-generation blockchain ecosystem goes to market, we’d like to hear from you.
