ReOps powers customer-centricity at a global scale
Delivering experiences that feel authentically local in every market, from Poland to Portugal, OLX designs every platform to feel native.
We want our platforms to connect buyers and sellers in ways that feel truly local. That means listening to and learning from over 2 million monthly users in real-time, while they’re actively using the platform.

That means adapting user flows, messaging, and incentives to local languages, cultures, and behaviors across languages like Polish, Portuguese, Ukrainian, Romanian, English and more.
Delivering that level of tailored customer-centric design at scale requires structure, and that’s exactly where ReOps comes in.
Scaling UXR with lean ReOps
Customer-centric design isn’t possible without continuous research. That’s why OLX is deeply committed to UX research, driving a major initiative to democratize it across teams.
Hi, I’m Ania
As a ResearchOps Project Manager on a lean team, I support every stage of the research process: activating localized participant pools, managing recruitment, customizing incentives, ensuring GDPR compliance, and evaluating and automating our tool stack, while keeping a close eye on AI innovation and ethics.
Challenge
When I joined OLX, recruiting relied heavily on external agencies, leading to inconsistent participant quality and frustrated stakeholders.
We needed to connect directly with real site users while enabling teams to move with agility.
Our goal was to establish processes and tools so that, by the second stage of maturity, researchers (excluding PDWRs) could operate independently, with ReOps providing guidance and support for specific requests as needed.
Solution
Reaching that level of maturity meant having the right systems in place. Ethnio stood out by letting us intercept real users mid-flow and manage multiple languages natively, delivering the flexibility and scale our global teams demand.
To get closer to our real users and democratize research, centralized ReOps was essential — we needed tools that enable us to recruit the right participants quickly and securely.

Today, we have a foundation built for scale, localization, and compliance.
Centralized ReOps in action
With Ethnio supporting our ReOps infrastructure, we are:
Managing multiple concurrent recruitment projects in one place
Building and maintaining panels by language and region
Launching intercepts in fully translated local languages
Customizing participant communication and incentives
Ensuring security and compliance at scale
Ramp up new projects across multiple platforms fast with minimal overhead
I’d be lost without Ethnio. It’s what gets you from setup to full speed within a month. If your tool vendor doesn’t support a clean setup, you can’t scale.

The impact at a glance
189 completed research participants
2M+ monthly pageviews on intercepts
130K+ localized participant emails sent
$11,000+ in tailored local incentive payouts
Managing multiple brands and markets with Ethnio
Having a centralized system is everything. Our dashboard provides real-time visibility into panel availability, recruitment progress, and research workload, ensuring resources go where they’re needed most.At any given time, I’m supporting up to eight active studies across OLX brands.

Everyone — from researchers to leadership — sees study statuses, participant engagement, and key insights instantly.
This shared view breaks down silos, eliminates bottlenecks and duplicated efforts, and keeps the organization aligned on one real-time snapshot.
Localization that builds trust
Real localization goes beyond translation. Ethnio supports full localization across every research module:
Intercepts, Screeners, and Panels
Translate intercepts into Polish, Portuguese, Ukrainian, Romanian, and more
Segment participants by geography, language, and brand
Scheduling & Communication
Send native-language invitations and reminders
Tailor messages to match brand voice and local norms
Contextual recruitment is key. Eight out of eleven platforms run web intercepts with Ethnio. We target specific user groups, like business users, and screen and book right away.

Incentives
Pay in PLN, EUR, USD, and other local currencies
Ensure fast, compliant delivery based on regional regulations
Supporting every type of research study
Whether it’s a beta test in Bucharest or a diary study in Lisbon, Ethnio supports all OLX’s research needs:
1:1 Interviews
Surveys
Diary Studies
Continuous Panels
Beta Testing
All fully localized, fully tracked, and fully scalable.
Building panels that slash recruitment time
OLX has built its own participant panels — segmented by language, brand, and user type — using Ethnio’s tools. These panels auto-update from intercepts and Google Sheets automations set up, keeping quality high and outreach agile.
I can start recruiting for a study tomorrow — even same-day. Before Ethnio, that was unthinkable.

OLX + Ethnio
Implementing centralized ReOps with Ethnio was a turning point. It gave us the agility to recruit efficiently and aligned perfectly with our teams’ openness to research. But this wasn’t just about reducing agency reliance — it was about getting closer to real users. Quickly finding the right participants became mission-critical as OLX doubled down on democratizing research.
By combining lean ResearchOps with Ethnio’s powerful tooling, OLX can:
Bring real user voices into every product decision
Deliver authentic, local-first experiences across markets
Operate efficiently without losing nuance
Build the global circular economy, one trusted trade at a time
