Lucian Mureșan is BIGDBM's Chief Technology Officer and the senior executive most responsible for turning the CEO's vision into scalable, working systems. He leads the company's technology direction across platform architecture, data infrastructure, cloud operations, and the engineering execution behind every core product initiative.
His role sits at the center of BIGDBM's growth, connecting strategy with delivery and ensuring the business can operate on secure, high-performance, privacy-first data systems. From large-scale processing pipelines to application architecture and analytics workflows, he drives the technical foundation the company depends on.
As the key technology leader directly after the CEO, Lucian helps shape not just how BIGDBM builds, but how it scales, innovates, and delivers enterprise-grade solutions with consistency, speed, and technical credibility.
Vali Macovei brings a CIO perspective centered on information strategy, operational resilience, and the disciplined use of big data across the business. He focuses on making sure the right data is available, governed, and aligned with the systems teams rely on every day.
His leadership connects infrastructure, security, and information management, helping BIGDBM turn data assets into reliable decision support for product, commercial, and customer-facing teams.
That role is especially important in a big-data environment, where scale only creates value when architecture, controls, and execution stay tightly coordinated.
Lesley Lempel brings a customer and commercial mindset shaped by relationship building, market positioning, and long-term growth. Her profile reflects a strong ability to connect client needs with clear value, turning complex capabilities into solutions customers can understand and adopt.
As Chief Customer Officer, she helps align onboarding, engagement, retention, and expansion so BIGDBM's customer experience is consistent from first conversation through long-term partnership.
Her focus is on trust, responsiveness, and measurable outcomes, ensuring the company grows not just by winning new business, but by creating durable customer success.
"BIGDBM's identity graph dramatically improved our match rates across every platform we activate on. The confidence scoring makes it easy to trust what we're putting in front of customers — and to explain it to stakeholders."
"The privacy-compliant workflows saved us months of compliance work. BIGDBM's team genuinely understands regulated data environments — they came in prepared, asked the right questions, and delivered a setup our legal team approved on the first pass."
"Real-time enrichment via BIGDBM's APIs gave us verified contact data that actually converts. The integration was fast, the documentation was clear, and the uplift in our outbound pipeline was visible within the first week."
"We've worked with several identity vendors over the years. BIGDBM is the only one that gives us confidence-scored results we can actually defend to our analytics team and C-suite. The audit lineage feature alone was worth the switch."
"BIGDBM's sports audience segments drove a 40% lift in engagement for our seasonal campaign. The targeting precision was unlike anything we'd achieved before, and the team was responsive every step of the way."
"BIGDBM's Identity Graph helped us finally unify our customer view across every channel. We had fragmented data spread across three CDPs — within a month of onboarding, we had a single source of truth we could actually act on."
We're always looking for passionate, curious, and driven people to help shape the future of data-powered outreach. If you're excited about building smart, scalable systems for modern teams, we'd love to hear from you.
