If reputation is acquired through acquisitions, maybe Railsbank can distinguish itself from much of the fintech crowd. In August 2020, the payments provider bought Wirecard's UK division, in a situation that its founder Nigel Verdon called "Enron for the fintech industry". Exclusive: Wirecard UK to be bought by Railsbank after downfall of parent company

Sifted Take
If you’re not from London (or one of 38 other major cities around the world) chances are you might not have heard of the transport and journey planning app Citymapper. But if you’re one of the app’s millions of users, you likely never catch a bus, head for an underground station or jump on a train without consulting it first. (You also, probably, firmly believe that Google Maps is no replacement.)
Citymapper wants to do so much more than tell you the best way to get from A to B. In 2017, it also started running buses and a shared taxi service, with a plan to reinvent not just buses but also how transport systems are run. Citymapper was all set to become the brain of London’s enormously complex transport system (then the world’s).
But it did not really turn out like that. In summer 2019, Citymapper ended its shared taxi service. Instead, it is now focusing on selling a “subscription to mobility” — also known, in non-tech speak, as tickets. But investors are reportedly growing disillusioned with its inability to find a business model that works (and worried about Uber and Google’s moves in this space). It may be a tricky road ahead for Citymapper.

Chunky card machines in cafes and restaurants are a tool of the past. Instead businesses are adopting to contactless card readers which process payments with a smartphone or tablet through point-of-sale (POS) apps.
The fintech companies that provide the payment hardware and software can make a cut on each transaction and generally win pretty sticky customers, so competition is fierce in this lucrative market.
Three of the market leaders are Sweden’s iZettle, which was bought by PayPal, Silicon Valley’s Square and SumUp in the UK.
Of the three BBVA-backed SumUp is the smallest but it is still a big UK fintech. Since it was founded in 2011 SumUp has expanded into more than 30 markets, helped by a merger with Rocket Internet’s Payleven in 2016.
SumUp now also does invoicing, bookkeeping, third-party integrations of payments and more. The big question is how long it can remain independent and if it can keep fighting with the bigger rivals.

Their system will allow disabled travellers to check exactly what features a room has, or choosy customers to pick, for instance, a room away from a noisy street. Pretty smart.

Europe's Airbnb competitor was on track for unicorn status. Then Covid-19 struck.

Interflora and FTD remain leaders in the market, but Bloom and Wild's postbox-sized service could put it at an advantage in the long run. Interestingly, it plans to sell no red roses for Valentine's Day in response to a survey, which found that 79% of customers wanted a more unique gift over the traditional choice.
