What the business is
Nox Mobility is developing a new generation of European overnight trains combining private modular cabins with standardised, efficiency-focused operations.
The bet
Each traveller will pay for a fully private cabin — transport and accommodation in one overnight journey — at a price point comparable to today's options
Starting capital
€2 million pre-seed; led by Berlin-based IBB Ventures, with Italian investor Tommaso Lucca and industry experts including Patrick Andrae
How it started
Founded in 2025 by Thibault Constant, Janek Smalla and Artur Hasselbach, bringing together experience in rail, mobility platforms and technology startups.
What happened
Demand for night trains in Europe has recently increased, with strong booking activity on key routes, but the market has contracted significantly over past decades on structural problems in service design and passenger experience. Nox pitches the opposite of the shared compartment: a fully private space per traveller, run like a boutique hotel on existing infrastructure, reducing the need for hotel stays and minimising travel time.
What has to be true
European night-train demand has rebounded with strong bookings on key routes, but decades of contraction left the product stale.
Traditional night trains make passengers share compartments; Nox bets travellers will pay for a fully private space.
A modular, high-density cabin system with standardised operations scales private overnight rail without new rolling stock.
Pairing transport with accommodation cuts hotel stays and adds usable overnight hours between city centres.
What can be applied
When an industry has shrunk for decades, the opening is not new infrastructure but a new unit — a private room instead of a shared berth — running on the rails that already exist.
Aftermath
As of the April 22, 2026 report, the pre-seed was earmarked for product development and establishing the company's position in the evolving European rail landscape. No train, route or launch date had been announced; the concept — private cabins on standardised modular operations, serving leisure and business travellers — was still pre-product.
