Relativity Networks Raises $22 Million To Make Data Centers Faster

Data center developers are expected to invest as much as $4 trillion by the end of the decade, but finding enough power and suitable locations is becoming increasingly difficult. Relativity Networks is betting that faster fiber could help data centers overcome some of those geographic constraints.

The company announced $22 million in SAFE note funding from Rhapsody Venture Partners, Bell Ventures and Faster Than Glass, among others. It also secured a $40 million follow-on order from an unnamed hyperscaler.

Hollow-Core Fiber Cuts Latency

Relativity Networks develops hollow-core fiber, which can transmit data 50% faster than conventional fiber. Instead of sending light through glass, the technology uses a hollow center containing air or a near-vacuum, allowing signals to travel closer to the speed of light.

For a signal traveling one kilometer, CEO Jason Eichenholz estimates that conventional fiber takes about five microseconds. Hollow-core fiber can reduce that to roughly 3.5 microseconds.

Connecting Data Centers Across Greater Distances

As AI systems grow, computing resources are increasingly spread across large campuses and multiple facilities. That makes network latency more important, particularly when separate data centers need to function as a single synchronized system.

Eichenholz sees an opportunity to connect existing facilities across multiple campuses, allowing companies to locate computing infrastructure closer to available power without sacrificing as much performance.

A 50% reduction in latency could effectively allow compute facilities to be separated by greater distances while maintaining similar networking performance.

From Compute To Geography

Eichenholz describes the evolution of AI infrastructure in three stages: first optimizing computing power, then improving networking within data centers, and now optimizing where computing infrastructure is physically located.

For Relativity Networks, faster fiber could therefore become an important piece of the next phase of AI infrastructure expansion.

Cyprus’ Strong Youth Employment Rate Still Does Not Guarantee Early Independence

Young people in Cyprus have a relatively high employment rate, but they leave the parental home later than the EU average, according to Eurostat data.

Cypriots left home at an average age of 27 in 2025, compared with 26.3 years across the EU. At the same time, 72.3% of people aged 20 to 29 in Cyprus were employed, well above the EU average of 65.5%.

Strong Employment Does Not Mean Early Independence

Only nine countries recorded higher youth employment rates than Cyprus. Iceland led at 85.3%, followed by the Netherlands at 84%, Malta at 82.1%, Switzerland at 78.3% and Germany at 77%.

Norway recorded 76.5%, Ireland 76.1%, Denmark 74.8% and Austria 74.6%. Eurostat said countries where young people leave home earlier generally tend to have higher youth employment rates.

Southern Europe Sees Later Moves

Finland had the lowest average age for leaving the parental home at 21.4 years, followed by Denmark at 21.8 and Estonia and Lithuania at 22.7. Croatia recorded the highest average at 31.5 years, followed by Greece and Slovakia at 30.9. Spain and Italy both stood at 30.2 years.

Across the EU, the average has remained close to 26 since 2002, rising only slightly from 26.2 years in 2024 to 26.3 years in 2025.

Cyprus Labour Market Is Cooling

The figures come as Cyprus’ labor market shows some signs of easing, although demand for workers remains relatively strong by European standards.

Separate Eurostat data showed Cyprus had the EU’s largest annual decline in its job vacancy rate in the second quarter of 2026. The rate fell to 2.6% from 3.3% a year earlier, but remained above the EU average of 2.0% and the euro area average of 2.1%.

Cost Of Living Remains A Factor

Housing and other living costs can also affect how quickly young workers establish independent households. Eurostat reported that Cyprus’ household consumption price level was 89.2% of the EU average in 2025.

A relatively lower overall price level does not eliminate affordability pressures for people on modest incomes. For younger workers, the issue can be whether wages are sufficient to cover rent, utilities, food and other basic expenses.

Cyprus therefore combines relatively high youth employment with a later transition to independent living, suggesting that access to work and the ability to afford a separate household do not always move together.
