Our take
Papernest helps customers manage their utility bills and subscriptions via its online platform. It predominantly focuses on streamlining the administration involved in moving house, like changing or cancelling water bills and gym registrations, with an additional service that works like a more conventional price comparison site for utilities like internet and gas. It is providing a much-needed service in what's proven to be an interestingly narrow and non-competitive niche.
The company so far has been partnering with real estate agency referrals to bring new customers on board. So the boom in people changing homes over the last few years is likely to have played strongly in Papernest’s favour. It has leveraged a strategic partnership with open banking firm Tink, using the company’s broader European coverage to springboard into more geographies.
Papernest seems something of a rare find: a solution that neatly resolves a large and material problem, that’s proven hugely popular, and yet that hasn’t inspired a flurry of would-be competitors. With the housing market still relatively hot, and mid-term moves inspired by the growing digital-nomad lifestyle still on the rise, Papernest seem to be in a rosy position. If it gets too rosy though, it may have to watch its back.
