The Challenge
The personal finance app space was full of budgeting tools that required discipline — weekly reviews, manual categorisation, goal adjustments. For the millennial audience Saever was targeting, this was exactly the friction that caused people to abandon savings apps within weeks. The challenge was building a savings product that worked invisibly: one that analysed spending, moved money, and grew investments without requiring a single deliberate action from the user.
Our Solution
We built Saever's AI engine on a spending pattern model that classifies every transaction and identifies safe amounts to sweep into savings — amounts small enough to be unnoticeable but significant enough to compound. Round-up rules apply automatically to every purchase, with the spare change routed to low-risk ETF investments via an FCA-regulated partner API. The AI learns each user's spending rhythm and adjusts the sweep amounts dynamically — more aggressive when the user has a good month, more conservative when expenses are high. PSD2 bank connectivity means the app works with any European bank account via Open Banking.

“The AI savings engine is genuinely magical. Users report saving 3x more than they did manually — not because they're trying harder, but because they don't have to try at all.”
