Head of B2B Marketplace – Founding Team
Location: London W1
Start: Immediate
Salary: £50,000–£80,000 per year + equity
The Opportunity
This is a founding team opportunity to build and scale a new B2B two-sided marketplace around an advanced AI platform.
Think about the marketplace mechanics behind platforms such as Upwork or Fiverr: building high-quality supply, activating that supply, generating buyer demand, creating successful transactions between the two and developing the commercial model that allows the marketplace to scale.
Early demand for the marketplace has already been proven.
The opportunity now is to turn that demand into a scalable commercial business and a major distribution channel for the platform.
We are looking for an exceptional Head of B2B Marketplace to lead that mission.
You will own the marketplace vision and bring it to life. That means defining the model, recruiting and activating partners, generating customer demand, managing marketplace economics and building the operation required to scale.
This is a hands-on General Manager-level role with ownership across marketplace strategy, go-to-market, operations, economics, partnerships and commercial performance.
You will not inherit a finished marketplace or established playbook.
You will have the authority and backing to build it.
The Role
You will build and scale a partner marketplace that drives adoption of an advanced AI platform. You will own both sides of the marketplace.
On the supply side, you will identify, recruit and activate partners who can sell, implement and support the platform.
On the demand side, you will build the B2B go-to-market engine required to generate customers, transactions and revenue.
Your challenge is not simply to acquire partners and customers. It is to build a marketplace where both sides are active, transactions happen consistently and the commercial model works at scale.
This is a General Manager-level role with full ownership of the marketplace as a business line.
What You Will Own
- Marketplace strategy and execution
- Building both the supply and demand sides of the marketplace
- B2B go-to-market strategy and execution
- Partner acquisition, onboarding, activation and performance
- Customer acquisition and conversion
- Marketplace liquidity and transaction growth
- Partner and customer retention
- Pricing, commissions, incentives and take rate
- CAC, LTV and marketplace unit economics
- Marketplace operations, quality and customer experience
- Identifying and removing barriers to marketplace growth
- Marketplace performance reporting and commercial KPIs
- The systems, processes and team required to scale
- Overall marketplace revenue and commercial performance
What We Are Looking For
Ideally, you have personally helped build or scale a genuine two-sided marketplace and understand how marketplace mechanics work in practice.
You understand the relationship between:
- Supply. Demand. Activation. Liquidity. Conversion. Retention. Pricing. Take Rate. CAC. LTV.
More importantly, you can explain what you have personally done to improve those metrics.
Experience within a B2B, talent, freelancer, expert, software, professional services or other two-sided marketplace would be particularly relevant.
We are also open to exceptional commercial operators who have built businesses, channels or go-to-market functions from an early stage and can demonstrate the ability to apply that experience to a two-sided marketplace.
You will have strong B2B go-to-market experience and know how to:
- Create demand from a standing start
- Acquire and develop commercial partners
- Build repeatable acquisition channels
- Improve conversion
- Understand what the data is telling you
- Identify where a commercial model isn't working and fix it
- Turn commercial activity into measurable revenue
You will be comfortable moving between strategy and execution.
This is not a role where you create the strategy and hand execution to somebody else.
Particularly during the early stages, you will be expected to stay close to partners, customers, acquisition, onboarding, conversion and marketplace performance yourself.
This Role Is Probably Not For You If
- Your marketplace experience is primarily managing products or sales through Amazon, eBay or other ecommerce marketplace channels.
- You have worked for a marketplace but have had little ownership over how the marketplace itself operates or grows.
- You are looking for a purely strategic Head of role with a large established team underneath you.
- You need an established playbook before you can execute.
- Or you are uncomfortable being personally accountable for commercial results.
The Person
- You are a natural leader who creates momentum and brings people with you.
- You are a conceptual thinker and an exceptional hands-on, early-stage executor.
- You are entrepreneurial, driven and commercially sharp.
- You see what needs to happen and take responsibility for making it happen.
- When something isn't working, your instinct is to understand why, test solutions and fix it.
- You form strong opinions, explain your reasoning and change your mind when the evidence is better.
- You are comfortable making decisions without having perfect information.
- You think strategically but stay close to execution.
- You thrive in a radically honest environment where problems are addressed directly, accountability is high and results matter.
- You do not wait to be managed.
Why Join?
- This is an opportunity to build a marketplace rather than simply manage one.
- The platform is advanced.
- Early marketplace demand has been proven.
- The next stage is execution and scale.
- You will work directly with the founders, own the commercial model and have the opportunity to build a major distribution channel from the ground up.
- As a founding team member, you will have significant ownership and the opportunity to materially shape how the business develops.
