Our Story

Built by network engineers,
for network engineers

We founded NetfillX to solve the growing complexity of network fill-request routing in modern distributed systems — because we lived that pain ourselves.

Intelligent routing should be simple, observable, and API-native

Modern distributed systems generate millions of network fill requests per second. Managing routing logic in-house means building complex, brittle infrastructure that pulls your team away from core product work.

NetfillX was built on a simple belief: intelligent fill-request routing should be accessible through a single API call, with full observability, sub-millisecond latency, and zero maintenance overhead on your side.

Q4 2023
Series A & 10,000 developers
$18M Series A. Surpassed 10,000 active developers across 64 countries.
2024
ML Route Optimizer ships
Machine-learning path optimization reduces average routing overhead by 47% across the platform.

Our core values

Developer-First

Every design decision starts with: does this make the developer experience better? Documentation, SDKs, error messages — all held to the same standard.

Transparency

We publish real-time status, post-mortems for every incident, and pricing with no hidden fees. You should always know exactly what you're paying for.

Reliability

99.99% uptime is a contractual commitment. We architect for failure at every layer so your fill requests always reach their destination.

Speed

Latency is a feature. Sub-millisecond routing decisions, instant API key provisioning, and a dashboard that loads in under 200ms — speed is everything.

Meet the founders

Three engineers who spent years building routing infrastructure at hyperscalers and decided to make it accessible to everyone.

Marcus Holt
Co-founder & CEO
Former Principal Engineer at Cloudflare leading the Argo Smart Routing team. 12 years building global CDN infrastructure. Obsessed with p99 latency and distributed systems correctness.
Priya Sundaram
Co-founder & CTO
Previously Staff Engineer at AWS Networking, core contributor to the VPC routing stack. Holds 9 patents in network path optimization. PhD in Computer Networks from UT Austin.
Daniel Osei
Co-founder & VP Engineering
Ex-Cloudflare Workers runtime engineer. Built high-throughput pipelines handling 40M+ req/s. Expert in Rust, eBPF, and kernel-bypass networking. Speaks at NANOG annually.

Headquartered in Austin, TX

Our main office is in downtown Austin. We operate a distributed team across North America and Europe with a strong remote-first culture.

We believe great infrastructure software comes from engineers who run their own tools in production. Every team member uses NetfillX daily.
