Real Estate Bees is a U.S. real estate lead marketplace, running since 2017. We generate motivated-seller leads through SEO, PPC, YouTube and social, and connect homeowners with investors across the country. Fully remote team, focused on building scalable acquisition channels.

Why this role exists:

We already work with several promoters — and it's producing results. But the process behind it is informal: no structured onboarding, no systematic outreach, no scalable framework. That's what this role fixes. We need someone to take what exists, build a real operating system around it, and then use that foundation to grow the network.

What does ownership mean here:

You own the channel and the revenue it produces. You'll start by getting your hands around what's already working — understanding the current promoter relationships, identifying gaps, and building the processes that make it repeatable. From there, you expand: more partners, better formats, a bigger team. You're not inheriting a machine — you're building one from rough parts.

What you'll do:

• Audit and systematize existing promoter relationships — document what's working, fix what isn't, and build the processes to make it scalable
• Design and own the full partner lifecycle: outreach, negotiation, onboarding, activation, and performance tracking
• Recruit and onboard new creators, influencers, affiliates and partners to grow the network
• Launch and run webinars, podcasts, interviews, sponsorships and content collaborations
• Hire and manage a partnerships team as the channel grows
• Own affiliate revenue and partnership performance end to end

What we are looking for:

• Hands-on experience working directly with influencers and content creators
• Experience with U.S.-based influencers
• Experience building or structuring partnership processes — not just executing someone else's playbook
• A track record of growing partnership revenue independently
• Ability to own results end-to-end
• Fluent English, written and spoken
• High energy, drive, and a bias for action — this role rewards people who make things happen

Nice to have

• Background in real estate, lead gen or SaaS
• Experience attending or presenting at industry conferences and live events

What you get

• Existing relationships to build on — you're not starting from zero, but you'll shape everything from here
• A direct line to leadership with full visibility into business metrics
• The chance to design the function your way, without an inherited mess to undo
• A team that ships fast and skips bureaucracy
• Visible, measurable impact on revenue — not abstract contribution

We are building one of the most powerful live-streaming platforms, already connecting 400K+ monthly active users through live events, interactive video chats, and real-time community experiences. Our mission is bold: bring joy, fight loneliness, and deliver safe, ad-free entertainment that keeps people coming back. This is a complex, fast-moving space, and we love it that way! So, you will join a passionate, expert team tackling everything from scaling AI-powered recommendations to launching high-impact, data-driven features that boost monetization and engagement. Every idea counts here, and every release reaches a massive global audienceWe are now expanding into Arab countries and Europe, enhancing content quality, and rolling out new features to keep users hooked. We are among the Top 5 streaming products in the US and rank in the Top 10 worldwide. Our next milestone: break into the global Top 5, and we are moving fast to make it happen

About your role: This role is an opportunity to build and scale the entire Partner Growth direction inside a high-load international product where partnerships directly influence acquisition, engagement, and revenue growth. You will own the strategy from the ground up: shaping processes, launching new acquisition initiatives, building relationships with creators and agencies, and creating a strong Partner Growth team around you.

You will work closely with Product, Marketing, Analytics, and Operations to identify growth opportunities, test new approaches, and scale successful initiatives across international markets. We are looking for someone who combines strategic thinking with hands-on execution and feels excited about building new systems in a fast-growing environment where decisions are made quickly and ownership is real.

In this role, you will

• Build and lead the Partner Growth function from scratch, including strategy, processes, team structure, and operational workflows
• Develop scalable growth strategies for partners, creators, and agencies across international markets
• Own partner performance metrics and identify new opportunities to increase engagement, retention, and monetization
• Build lead generation pipelines and scale acquisition channels
• Launch and optimize outbound partnership initiatives and creator acquisition strategies
• Work closely with Product, Analytics, Marketing, and Operations teams to launch growth initiatives and improve partner experience
• Analyze large-scale performance data to uncover growth levers and optimization opportunities
• Drive experimentation culture through A/B testing and data-driven growth decisions
• Hire, mentor, and grow a high-performing Partner Growth team
• Influence product roadmap by bringing partner and market insights directly into product development discussions

It’s all about you

• English B1+
• 3+ years of experience in Growth, Partnerships, or Business Development roles
• Proven track record of building lead generation pipelines and scaling acquisition channels
• Experience with influencer and creator marketing
• Experience with partnerships and outbound acquisition strategies
