Ten years after it was founded, Tinder

has become the most successful dating app in the world: Tinder has now been downloaded more than 530 million times worldwide

The principle is very simple: users look at photos of potential partners on their smartphones.

A swipe to the left means no interest.

However, if both swipe to the right, there is a match and the flirting can begin.

But this simple "first look principle" is apparently too simple for many.

There is no longer a match between the app and the young target group.

Generation Z singles don't tinder, they turn to alternative online services to look for a partner.

The result: Tinder loses market share.

The number of downloads is declining, sales and profits have collapsed, and competitors like

are catching up.

The share price of the dating giant

, which in addition to Tinder also owns other dating portals such as

or

, has collapsed since the beginning of the year.

The new CEO

to the top of the Match Group just five months ago

to reorganize the business.

He now has Tinder boss

dismissed and runs the dating portal itself. Our colleague Anna Driftschröer describes how Kim wants to ensure that things fit between Tinder and its users again soon: Tinder - The Story of a Crash.

The business news of the day:

• Sixt wants to order 100,000 electric cars in China:

  The car rental company

  Sixt

  wants to buy more than 100,000 electric cars from the Chinese manufacturer

  BYD

  by 2028 .

  Both companies have signed a corresponding agreement, Sixt announced.

  As the first BYD model, Sixt will offer the fully electric Atto 3 as a rental car.

• Volkswagen and BMW increase sales in the USA:

  Despite the lack of chips and problems in the supply chain, the German car manufacturers VW and BMW increased their sales in the USA again in the second quarter.

  Volkswagen increased sales by 12 percent to almost 90,000 new vehicles, benefiting primarily from demand for SUV models such as the

  Atlas, Tiguan and Taos.

  BMW

  increased sales by 3 percent.

  The US manufacturer

  General Motors

  reported sales growth of almost 25 percent, and GM shares then increased by double digits.

• Investors are drawing hope again:

  After the severe losses in September, the German share index

  Dax

  started October with strong gains.

  On Tuesday, the Dax temporarily climbed back above the 12,600 point mark and has made up more than 700 points since the September low.

  Investors are hoping that the forthcoming interest rate hikes by the central banks will not be as strong as they were recently and that the dreary September will be followed by a golden October.

What else kept us busy:

• The Chinese make a radical cut at Wolford:

  After the departure of COO Andrew Thorndike, the crisis-plagued hosiery manufacturer Wolford still hasn't calmed down.

  Now the Chinese owner Fosun is taking action.

  Our colleague Hannah Steinharter describes what the radical cut looks like at the traditional brand.

• Controversy over Web 3.0:

  Blockchain fans want to create a new generation of the Internet with Web 3.0, which is based on the blockchain and thus functions in a decentralized manner.

  Computer scientist and blockchain expert Molly White, on the other hand, believes Web 3.0 is a "huge rip-off pouring gas on our already smoldering planet".

  You can read at manager-magazin.de where White sees the problems and why she complains about "perverse financial misguided incentives".

• Creativity workshop:

  Creativity is one of the most important skills in the modern working world.

  Anyone who can reliably develop surprising ideas is not only more successful today, but will remain so.

  That's why the new course by my colleagues from manage › forward is exactly what it's all about: successfully developing and implementing innovative ideas.

  The colleagues have summarized everything important about the course here – readers of this newsletter receive a discount of 40 euros with the code DER-TAG.

My recommendation for the evening:

• How to save energy through better building:

  Wind turbines and heat pumps alone will not solve Germany's energy problems, says

  Lamia Messari-Becker

  , expert for sustainable building.

  She pleads for more creativity in climate protection: The professor of building physics explains why the use of a heat pump in an uninsulated building is insane and why many political regulations make climate protection more difficult than possible.

  Nevertheless, she sees enormous potential in the construction and residential sector.

  According to the expert, 25 percent of the thermal energy can be saved just by going into the boiler room.

  We warmly recommend the interview with Messari-Becker on manager-magazin.de to anyone who is building a house, converting a house energetically or simply wants to save a good deal of heating energy this winter.
