We are the team behind Feldera.
Since 2018, we have worked on one problem: incremental computation. Feldera makes it available to all engineers.

We are researchers. In fields from data infrastructure to security products, we saw the same pattern again and again. Teams wrote ad-hoc solutions for problems that were really incremental computation problems. These solutions were brittle, hard to maintain and slow, and they reduced product velocity.
We joined to advance the state of the art and the state of practice of robust incremental computation. That work led to DBSP, our award-winning research on incremental computation for query languages like SQL. We founded Feldera to make this technology available to all engineers, so that legacy compute infrastructure does not hold them back on hard data problems.

Mihai Budiu
Chief Scientist / Co-Founder
Mihai has designed and built high-performance systems across Big Data platforms, distributed systems, compilers, machine learning, network infrastructure and reconfigurable hardware. He is a co-creator of DBSP, Feldera’s core engine. Four of his papers have won “test of time” awards. He previously worked at VMware, Barefoot Networks, and Microsoft. He holds a PhD from Carnegie Mellon University.

Ben Pfaff
Chief Engineer / Co-Founder
Ben is a veteran systems engineer working on operating systems and distributed systems. Before Feldera, he worked at Nicira Networks as a founding engineer and then at VMware. He is best known as the founder and long-time lead developer of Open vSwitch and OVN, and has 25 years of free and open source software experience. He holds a PhD from Stanford University.

Gerd Zellweger
Head of Engineering / Co-Founder
Gerd is a systems builder specializing in operating systems, concurrency, networks, and hardware-software interaction. Before Feldera, he led scalable multi-core OS design efforts at VMware and ETH Zurich. He has won two best paper awards. He holds a PhD from ETH Zurich.

George Bulakh
Engineer
George is a full-stack software engineer who holds a master’s degree in Computer Science from Odesa Polytechnic National University. He has diverse experience working with automotive HMI systems, Triple-A videogames, blockchain and web apps.

Swanand Mulay
Engineer
Swanand is an engineer from India with a hacker’s mindset and a talent for building software and systems. If he’s gone quiet on sharing memes, then he’s probably off in mountains or some adventure. Legend says he still can’t write a good bio for himself.

Tristen Cross
Founding Product Marketing Manager
Tristen Cross has been in product marketing for over 10 years. She’s been the founding product marketer at four startups, building positioning, messaging, and go-to-market strategy at companies like Hopin, CloudBees, and Anomalo - with a brief detour to co-found a natural foods company, because you only live once.

Anand Raman
Founding Forward Deployed Engineer
Anand is an engineer who helps Feldera’s customers architect and scale their data processing pipelines. His background includes data engineering, data orchestration, and cloud solution architecture. He enjoys working with customers across industries, from startups to large enterprises, to define creative solutions to difficult data challenges.

Jyotshna Yaparla
DevOps Infrastructure Engineer
Jyotshna is a DevOps and infrastructure engineer focused on keeping Feldera’s engineering systems running smoothly. Her work spans CI/CD pipeline automation, Kubernetes cluster management, cloud infrastructure, release engineering, and Kafka integrations. She holds a Master’s degree in Computer Science.

Jason Mueller
Head of Sales
Jason Mueller is building Feldera’s go-to-market team. With over 15 years of experience leading sales at high-growth startups - including Snowflake (in the early days), Opaque Systems, and Spectro Cloud - he knows what it takes to bring technically complex products to market and earn the trust of engineers and technical leaders. Jason leads with empathy and works shoulder-to-shoulder with his team. He lives in the Bay Area with his wife and three kids.

Emily Anderson
Head of Operations
Emily Anderson is building the systems and structures that let Feldera scale. Her background spans operations and marketing in early-stage startups and global enterprises, including Microsoft and Booking.com. She has a bias toward systems thinking and a belief that the best operations work is invisible: when it’s done right, everyone else just gets to move faster. Emily lives in the Bay Area with her family and is equally at home in a kitchen or on a golf course.

Xavier Bestel
Backend Infrastructure Engineer
Xavier is a systems engineer with almost three decades of experience making low-level code fast and robust. He has built compilers and formal verification tools at STMicroelectronics and Mentor Graphics, ported Linux to custom ARM silicon for VoIP hardware, architected France’s nationwide legal time synchronization network at Gorgy Timing, squeezed voice recognition models onto Sonos speakers, and moved a high-frequency trading engine to io_uring and a unikernel. He co-founded a VoIP startup along the way. At Feldera he works on connectors and platform infrastructure, in Rust. He lives near Grenoble, in a small village high in the French Alps, and he enjoys that very much.

Song Huang
Engineer
Song is a software engineer with an interest in databases and data infrastructure. After getting tired of teams hacking together solutions using Spark, Flink, Snowflake, and ClickHouse, he realized there had to be a better way and set off to build it with Feldera. He also loves solo traveling, history, and cooking, and struggles with the idea of writing in third person and having photos of himself on the internet. Occasionally practices the arcane art of writing code, and even more rarely, reading code.

Tizian Bluntschli
Engineer
Tizian is another physicist turned data scientist turned engineer that helps Feldera pressure test its new features before they go into production. If he isn’t impatiently waiting for his bread doughs to rise he is likely to be found on some park bench with a good book.

Jack Gale
Lead Product Designer
Jack has spent his career making complex data products feel simple and intuitive. He was a design leader at Ethyca and the founding product designer at Bigeye, both venture-backed data startups. He also worked at NASA building mission assurance and planning tools for space. He holds a BFA in interaction design and an MS in human-computer interaction. He lives in Connecticut with his wife and son.
