We are not looking for a Media Buyer.

We are building the supply backbone of a next-generation on App Growth company.

Appiness is an AI-powered App Growth Partner turning app users into shoppers.

We don’t resell CPI traffic.

We build incrementality across traffic ecosystems.

Now we’re hiring the person who will own and scale our Supply-Side Intelligence Layer .

Main Responsibilities

Your Mission

Design and scale a diversified, resilient, high-margin supply ecosystem that:

• Adds differentiated traffic sources (DSPs, CTV, OEM, premium)
• Protects incrementality (our USP)
• Eliminates publisher dependency risk
• Drives new GP through strategic supply expansion
• Prevents CPI/CPA commoditization

You will decide where and how we scale.

This is a business-critical leadership role.

What You’ll Actually Do

Expand the Supply Universe

You will identify, evaluate, negotiate and activate:

• New & relevant App Networks
• Programmatic DSPs
• Performance DSPs
• CTV platforms
• OEM & device-level partnerships
• Premium / non-commoditized inventory

You understand the structural difference between network traffic, DSP buying, OEM supply and walled gardens.

You don’t just “test traffic.”

You architect supply strategy.

Own MMP & Incrementality Logic

You have real experience in: Adjust/AppsFlyer / Singular or similar

You understand:

• Postbacks & event mapping
• SKAN complexity

Deep Network & DSP Experience

And you understand how buying logic actually works.

You know how supply is structured.

You know what “easy scale” really means.

You know how to protect margin.

Understand the Ecosystem

You know how campaigns operate across: Meta| Google App Campaigns| TikTok| Apple Search Ads

You understand how to compare their incrementality vs external DSP supply.

You think cross-channel.

How Success Looks Like

• New high-quality publishers onboarded
• Clear diversification (no single publisher >30%)
• Strong GP per new supply partner
• Measurable incremental revenue impact
• Strong margin protection
• A resilient supply stack

Your profile

Who You Are

• 6+ years in mobile performance ecosystem
• Strategic, commercially sharp
• Comfortable negotiating with networks & DSPs
• Obsessed with incrementality
• Skeptical of inflated scale

Why us?

Why This Is Big

You will own one of the two core pillars of the company.

Your decisions directly impact:
