Lendable is a UK fintech that funds unsecured personal loans by connecting borrowers with institutional investors. It operates a two-sided marketplace; capital from pension funds and hedge funds funds the loans rather than using its own balance sheet, while customers get quick, digital loans. The platform uses AI/ML driven credit scoring to automate decisions and funding, with instant approvals and funding often within hours; eligibility checks do not impact credit scores. It offers loan amounts £1,000-£25,000 for 1-5 years and also provides Autolend car finance and Zable credit products (including in the US); its goal is to expand access to consumer credit across a broad UK audience by scaling its platform and product suite.

India's Metafin secures $10M debt facility to expand rural solar financing

Metafin, an India-based solar lending platform for rural micro, small and medium enterprises and households, has secured a $10 million structured debt facility from London-headquartered advisor Lendable. The funding will expand solar financing in India's rural regions, targeting customers currently reliant on diesel power. The facility, drawn from Lendable's transportation and energy fund, follows Metafin's separate $10 million Series A round. The company has financed over 6,500 projects across 4,000 villages in five states and reached profitability in fiscal year 2024. Metafin uses proprietary Internet of Things technology to track energy use in real time and can remotely disable financed solar plants when payments stop. By March 2025, it reported assets under management of Rs 81 crore and an annual revenue run rate of Rs 22 crore.

Consumer credit firm Lendable launches £20 a month mobile tariff

Consumer credit firm Lendable launches £20 a month mobile tariff. Consumer credit firm Lendable has launched a new mobile phone tariff for £20 a month, joining other fintech groups in attempting to disrupt the dominance of major carriers. The plan includes unlimited 5G data, calls and texts on Vodafone's network, plus 10GB of roaming across 38 nations. The British company has become the latest financial technology firm to expand into telecommunications in a bid to unlock new revenue streams. Lendable, founded in London in 2014, joins a string of firms in other countries tapping into the telecoms market and seeking to build 'super-app' systems that combine banking, shopping and communications. Revolut recently announced plans for its own mobile virtual network operator in Europe, while Klarna will launch a $40 per month plan in the US. Unlike mainstream providers, these operators do not own the wireless infrastructure they depend on, which allows them to avoid heavy fixed costs while competing on prices for consumers. New tariff: Consumer credit firm Lendable has launched a new mobile phone tariff for £20 a month How this is money can help. Similarly, Monzo is reportedly exploring the launch of a digital SIM, which connects to a mobile network without a physical SIM card, and offering monthly contracts. Mobile virtual network operators like Giffgaff, Voxi, Tesco Mobile and Lebara offer mobile services by 'piggybacking' off the network provided by big UK operators. Celebrities have also jumped on the trend. Ryan Reynolds-backed budget brand Mint Mobile was sold to T-Mobile US for $1.35 billion in 2023, while Donald Trump's family business has licensed its name to launch a mobile service. Lendable's plan will be powered by US-based tech company Gigs, which provides the operating system, and will be available on the Lendable-owned Zable app, which has 2 million customers. Martin Kissinger, co-founder and chief executive of Lendable, said that unlike other fintechs focused on current accounts, international payments and trading, Zable offered cost-saving options with the aim of lowering bills. When asked about fundraising, Kissinger told Reuters Lendable was a profitable and well-funded business. He said: 'At the moment, we are not thinking about any kind of listing, as there is still a lot of building to do.' Kissinger declined to comment on a potential initial public offering on the London Stock Exchange. Diy investing platforms. interactive investor. Flat-fee investing from £4.99 per month
