The best of boutique hotels and of Airbnb, bigger rooms, direct access from your smartphone, customer service on Whatsapp: Berlin-based proptech Numa Group will open a 134-apartment block of flats in the second half of the year, the Connection complex, in partnership with Silverfinch Property & Asset Management and Connection Property Development.

A new high tech concept in short-term home letting is coming to Hamm. At 23-25 rue de Bitbourg, German property developer Numa Group will open a 3,400m2 residence in the second half of the year, housing 134 new-style 25m2 flats for rent for varying periods depending on the customer’s needs. That will make Numa present in 16 cities and 34 countries, with a total of 6,000 flats and more than €2bn in property assets under management.

As is the case wherever it has set up shop, the Berlin-based proptech company has teamed up with a partner, in this case two: Connection Property Development and Silverfinch Property & Asset Management. “The cooperation gives us a foothold in the Luxembourg market and allows us to get involved in a project that reflects our vision of modern living,” explained Numa Group chairman Dimitri Chandogin. “With Hamm, we have chosen a site that is convincing not only strategically, but also in terms of its dynamic development.”

The inclusion of this residence marks an important step in Connection Property Development’s commitment to offering a wide range of useful services within the mixed-use building and strengthens the overall appeal of the Connection complex in Hamm, its developers say. “We believe that Numa’s integration into Connection will make a significant contribution to the attractiveness of the building and the Hamm business park,” stated Connection Property Development director Kindy Fritsch, grandson of the late Paul Leesch, founder of the Cactus retail group.

80% of process digitalised

There is the building itself, located halfway between the airport, Kirchberg and the city centre, but above all there is the technology developed by Numa, launched in 2019 and which, according to the official press release, will cut operating costs by 60% compared with a conventional hotel. Check-in, check-out, access to rooms via smartphones, reservations, allocation of accommodation, property maintenance, accounting: 80% of the processes have been digitised with a view to customer satisfaction, as also demonstrated by the emphasis placed on high-speed wifi in every room.

The target clientele is not satisfied with traditional hotel services and takes a dim view of the accommodation available on Airbnb, which has provoked a great deal of criticism and calls for new regulations.

On 12 March, Numa announced its arrival in the British capital with 83 flats, and on 2 April its participation in two projects in Spain and Portugal. It is due to open a former Paris hotel with 40 rooms and 78 beds before the Olympic Games, located between the Canal Saint-Martin and the Parc des Buttes Chaumont.

Just to get an idea of prices, we searched for bookings not too far from Luxembourg. For the Brussels Lief site, from 24 to 26 May, for two people, rooms ranged from €157 to €200 for 20m2 to 46m2; and at Frankfort Blau and Bloc, on the same dates and under the same conditions, from €82 to €118 for 20m2 to 30m2.

Over €100m raised

At the end of September, the group announced that it had raised €59m in a series C round from Verlinvest, the investment company backed by the families behind AB Inbev, and Cape Capital, in addition to existing investors Headline, Cherry Ventures, DN Capital and Soravia. Started under the Cosi Group brand, Numa had already raised €20m in 2021 and €45m the following year.

In 2023, Numa strengthened its presence in the key markets of Germany, Italy and Spain through selected acquisitions, and entered new strategic markets in Norway, Portugal, Belgium, the Czech Republic and Switzerland.
