Byteport Moves Terabyte-Scale Files 10x Faster Than Anything Else

The Macro: Moving Big Files Is Still Embarrassingly Hard

We live in an era of gigabit internet, cloud everything, and instant access to information. Unless your file is 50 gigabytes. Then you are back to the dark ages. Uploading a large dataset for AI training, transferring satellite imagery for analysis, moving robotics data from a warehouse to the cloud. These operations routinely take hours or days, fail partway through, and require babysitting.

The problem is TCP. The protocol that powers internet file transfer was designed in the 1980s for reliability, not speed. It backs off when it detects network congestion, which sounds reasonable until you realize that modern high-bandwidth connections are almost never actually congested. TCP treats every packet drop as a signal to slow down, even when the network has plenty of capacity. The result is that file transfers use a fraction of available bandwidth.

Aspera, now owned by IBM, solved this years ago with their FASP protocol. But Aspera is expensive, enterprise-heavy, and not designed for the modern cloud-native stack. Signiant serves media and entertainment. But there is a gap for a modern, developer-friendly file transfer solution that works for robotics companies, satellite operators, AI labs, and any organization moving very large files regularly.

The Micro: A CERN and Netflix Alum Building a Better Protocol

Jayram Palamadai founded Byteport. His background includes CERN and Netflix, both organizations that deal with enormous data volumes. He is currently a solo founder from San Francisco, part of YC Winter 2026 with Tyler Bosmeny.

The core product is DART (Dynamic Accelerated Record Transfer), a file transfer protocol designed specifically for large file uploads. The claim is 10x faster than TCP, which is consistent with what other UDP-based transfer protocols achieve. The target range is files from 1GB to 100TB.

The customer base spans robotics, satellite, AI, and enterprise applications. These are industries where data volume is growing explosively and traditional file transfer methods are a genuine bottleneck. A robotics company generating terabytes of sensor data daily needs to get that data to the cloud for processing. A satellite company downloading imagery needs to move it to customers. AI labs need to transfer training datasets between data centers.

Byteport recently consolidated from byteport.io to byteport.com, suggesting the company is maturing and investing in brand infrastructure.

The Verdict

Byteport is solving a boring problem that turns out to be worth a lot of money. File transfer is not glamorous, but companies that move large files regularly will pay well for a solution that reliably runs 10x faster than the alternative.

The risk is that the cloud providers build this natively. AWS Transfer Family, Azure Data Box, and similar services already handle large data movement. If they add high-performance transfer protocols comparable to DART, Byteport’s market shrinks. But cloud providers tend to build one-size-fits-all solutions, and specialized transfer protocols that optimize for specific use cases have historically maintained their value.

The solo founder risk is real. Building network infrastructure as a single person is ambitious. Byteport will need to hire quickly to support enterprise customers and continue protocol development.

In 30 days, I want to see benchmark comparisons against Aspera and Signiant. In 60 days, the question is customer concentration. How many paying customers, and is revenue diversified? In 90 days, I want to know about the protocol reliability. Speed matters, but reliability matters more for mission-critical data transfers. Zero-loss guarantees on 100TB transfers would be a strong selling point.
