Executive leadership

We built our careers making enterprise data reliable. Now we're applying that foundation to the bigger challenge: making the AI that depends on it trustworthy.

What brought this team together

What brought this team together

The leaders at Bigeye came from Uber, Datadog, Microsoft, Visa, Cisco, and IBM. They built the pipelines, the platforms, the security architectures, and the customer success motions that enterprise data teams relied on. They saw, from the inside, where data and governance failures had the most impact on the organizations that depended on them.

That shared background shapes everything at Bigeye. The leadership team has spent their careers working on data quality, governance, and the organizational challenges that make data unreliable at scale. That experience informs every product decision, every customer engagement, and every strategic bet the company makes.

Executive profiles

Executive profiles

Eleanor Treharne-Jones

Chief Executive Officer
"Trustworthy AI is a governance problem as much as a technology one. Building companies that solve it is what I've spent 20 years preparing for."

Eleanor brings more than 20 years leading global SaaS and data companies through the exact transitions enterprises are navigating now. As CEO at Kensu, she led a data observability company through growth, cutting issue resolution times and expanding its enterprise footprint. As CRO at Odaseva, she scaled revenue operations for a Salesforce data protection platform serving regulated enterprise customers. As SVP at TrustArc, she ran data governance and privacy business lines across Europe, the U.S., and APAC, overseeing some of the most complex regulatory environments in the world. Her conviction: trustworthy AI is a governance problem as much as a technology one, and organizations that treat it otherwise will spend more time cleaning up problems than shipping value.

Current focus

AI trust platform strategy, aligning product direction with enterprise governance requirements and positioning Bigeye as the standard for data and AI reliability in regulated industries.

Kyle Kirwan

Co-Founder and Chief Strategy Officer
"The best problems to solve are the ones the market hasn't named yet. Strategic partnerships and zero-to-one projects are where I spend my time."

Kyle co-founded Bigeye after scaling Uber's data and experimentation platforms during hypergrowth. As a founding data scientist on Uber's experimentation platform, he standardized metrics across thousands of A/B tests, working at a scale where data quality problems weren't inconveniences. They were business risks. He saw that manual pipeline testing didn't scale, then experimented with ML models on data profiles to identify anomalies automatically. That technique became what the industry now calls data observability. At Bigeye, Kyle leads strategic partnerships and prototype development, finding the problems worth solving before the market names them.

Current focus

Developing partnerships and prototype capabilities that extend Bigeye's platform into emerging AI governance use cases.

Egor Gryaznov

Co-Founder and Field CTO
"Enterprise AI governance starts with understanding what your data is actually doing. Making that visible is what this work is about."

Egor co-founded Bigeye after a decade at Uber as a Staff Engineer and member of the original data warehouse team, joining in 2014. He built Uber's first SQL bootcamp, helping hundreds of employees work with data more effectively, and bridged business and engineering teams across a platform supporting hundreds of petabytes. He watched data quality issues silently undermine decisions at a scale most organizations never encounter. As Field CTO at Bigeye, he brings that operational experience directly into enterprise customer engagements, working with data leaders on the specific architectural and governance problems that slow down AI initiatives before they start.

Current focus

Working with enterprise leaders to design data and AI governance strategies built on observability, lineage, and trust, including governing how AI agents access and use information.

Functional leadership

Rashmi Ramesh

VP of Product
"Complex systems should produce intuitive outcomes. My job is to translate Bigeye's platform depth into products data teams actually use."

Rashmi brings deep expertise in cybersecurity, data platforms, observability, and AI to Bigeye's product organization. In leadership roles at SentinelOne, Tanium, and Cisco, she built products from scratch and scaled them into widely adopted platforms, leading global teams across APAC, Israel, Europe, and the U.S. She created the "Path to CPO" podcast and an "AI Product Management" series, both reflecting her commitment to making the craft of product leadership more accessible. She holds an MBA from The Wharton School.

Current focus

Defining Bigeye's product strategy, translating enterprise AI governance requirements into capabilities that make data trust systematic, auditable, and scalable.

Mohamed Alimi

VP of Engineering & Applied Science
"The engineering behind AI trust has to be as rigorous as the promise. That's the standard I hold the team to."

Mohamed built Datadog's AI Observability product suite from concept to launch, leading a team of 40+ engineers and applied scientists through one of the fastest product buildouts in Datadog's history. He presented LLM Observability at the Datadog DASH 2024 opening keynote, giving the work a public reference point. Earlier, he led teams at Amazon Alexa AI on large-scale web QA and streaming systems, and at MathWorks on scientific computing tooling. His doctorate in theoretical computer science covers probabilistic cellular automata, fault-tolerant computation, and Kolmogorov complexity. These are rigorous foundations that show up in how he thinks about building reliable systems at scale.

Current focus

Leading engineering and applied science across data observability, lineage, sensitive data scanning, governance, and runtime AI policy enforcement for data-rich, highly regulated enterprises.

Joan Pepin

Chief Information Security Officer
"Enterprise security shouldn't be a roadblock. I build the systems that let organizations move fast and stay safe."

Joan has spent 27 years in cybersecurity, building security programs at companies where the stakes were genuinely high and the complexity was real. As CISO at Sumo Logic, CSO at Auth0, and BISO at Nike Digital, she operated at the intersection of scale, compliance, and speed. She also co-founded a security startup, giving her the perspective of building security from both sides of the table. Her experience spans early-stage companies through global enterprises preparing for major exits. Her belief: practical, scalable security, not bureaucratic overhead, is what closes deals, passes audits, and gives leadership the confidence to move.

Current focus

Ensuring Bigeye's AI trust platform meets the compliance and security requirements of highly regulated enterprise customers, building organizational trust from the inside out.

Tony Peck

Vice President of Customer Success
"Adoption isn't enough. Customers need to rely on their data, and that's what my team is here to make sure they can do."

Tony brings more than 20 years leading customer-facing organizations in SaaS and data infrastructure. As VP of Customer Success at Matillion, he led global Customer Success, Professional Services, and Support for enterprise cloud data adoption, managing a full post-sales motion at the scale that comes with a market-leading product. Earlier, in senior leadership at Ping Identity, he scaled Professional Services through a private equity acquisition and IPO, building the organizational resilience those transitions require. His expertise spans customer lifecycle management, enterprise engagement models, and aligning customer outcomes with durable revenue growth.

Current focus

Building the customer success motion that helps enterprises move from data reliability pilots to production-grade AI initiatives.

Patricia Miron

Chief Marketing Officer
"The market is asking for AI trust. My job is to build the narrative and the engine that makes sure they find Bigeye."

Patricia brings more than 20 years scaling global technology, SaaS, and fintech at some of the most demanding companies in the world. At Microsoft, she served as COO for the $14B U.S. SMB segment. At Visa, as SVP of Global Client Services, she turned around a roughly $50M services portfolio and improved NPS by 20 points. At Intel, she led global programs across product and go-to-market. Most recently as CMO at DispatchTrack, she repositioned the company from point solution to broader platform and built its first integrated go-to-market engine from scratch. She holds an MBA from Duke University's Fuqua School of Business.

Current focus

Building Bigeye's go-to-market engine, aligning product, marketing, and sales development to drive awareness and enterprise pipeline for the AI trust platform.

Drew Stark

Head of Sales
"The AI trust conversation is happening in every enterprise boardroom. Making sure Bigeye is in the room is what I'm here to do."

Drew has spent 15+ years scaling enterprise data and software sales in environments where the technology is complex and the stakes are high. At Ataccama, he rose from Account Executive to VP of Sales for North America, delivering 318% revenue growth to $50M+ ARR, contributing more than 60% of global revenue year-over-year, and playing a central role in the Bain Capital investment. Earlier at IBM, he managed marquee accounts generating $13M+ in annual revenue. At Bigeye, he has led some of the strongest revenue quarters in the company's history.

Current focus

Building the enterprise sales motion for an AI trust company, translating complex platform capabilities into specific, measurable business outcomes for data-intensive organizations.
