About The Role
VOX Solutions is scaling True Signal, a disruptive AdTech ecosystem that transforms real-time telco data into high-intent revenue. True Signal's mobile SDK sits inside operator and publisher apps, reading on device signals, app opens, web visits, roaming triggers, SMS events — and converting them into consent-based campaigns delivered through push notifications and SMS+.
We have active commercial traction in MENA and CEE and a product built to scale to 20+ markets.
The next phase is demand: filling our growing inventory with high-value advertisers, agencies, and performance partners who will pay a premium for audiences this precise.
As a Head of Sales - Demand Side, you will be the commercial engine behind True Signal's revenue growth. Working in close partnership with the VP of AdTech, you will build and lead a general sale organization targeting brands, media agencies, and affiliate partners converting them into paying customers and growing those accounts over time.
Your ideal customers are CMOs and marketing teams at direct brands, media buyers at agencies managing digital and mobile budgets, and affiliate managers at companies with performance programmed in verticals like betting, fintech, retail, and travel.
You will report into the VP of AdTech and operate as part of a joint GTM team alongside the VP of AdTech, CBDO, CEO, and CPAO. This is a hunter-first, builder role: you will personally close deals while simultaneously constructing the team, process, and culture that scales demand globally.
