Rule Raises £800K Pre-Seed to Gamify Saving and Tackle the “ADHD Tax”

London-based fintech startup Rule has raised £800,000 in a pre-seed funding round to accelerate the launch of its gamified saving app. The round was led by London Venture Partners (LVP) with participation from Bethnal Green Ventures (BGV), signalling strong investor confidence in the company’s mission to help users build better saving habits.

Rule is building a mobile “save-to-win” game that tackles what it calls the “ADHD tax” — the additional financial cost and stress faced by people who struggle with impulse spending and inconsistent money management. In its closed beta, the app has already helped users collectively save over £100,000, demonstrating early traction and engagement with its concept.

Rather than making saving feel like a chore, Rule centres its experience around a Tamagotchi-style squirrel avatar that grows happier and stronger as users deposit money and hit milestones. This gamified approach rewards consistent saving behaviour and creates an emotional feedback loop. The founders say most money apps are designed for neurotypical users, leaving a significant group underserved — particularly those with ADHD or similar attention and behavioural challenges.

With the £800,000 boost, Rule plans to move from beta to a full public launch while expanding its feature set and product team. The funding will be used to improve the user journey, enhance gamification mechanics, and build new ways to turn saving into a sustainable habit rather than a one-time goal.

Investors leading the round noted that Rule sits at the crossroads of behavioural science, financial wellness, and gaming — an intersection they see as ripe for innovation. London Venture Partners, best known for backing hits like Supercell, Unity, and NaturalMotion, said Rule represents a rare and promising application of game design principles to personal finance. Bethnal Green Ventures, which specialises in tech-for-good startups, highlighted Rule’s potential to improve financial wellbeing through accessible, user-centred design.

The funding round comes as the UK’s fintech ecosystem continues to evolve. While many startups focus on payments, investing, or credit, few are tackling the behavioural aspects of saving head-on. Rule’s approach reframes saving as play — using game design and behavioural nudges to engage users who might otherwise avoid traditional finance apps. Its focus on the so-called “ADHD tax” taps into a growing awareness of neurodiversity and the need for inclusive product design.

The startup’s next steps include converting its beta community into a wider user base while introducing new features such as social challenges, habit tracking, and personalised financial education. The goal is to transform saving from a passive financial task into an active, rewarding experience. The team also plans to explore partnerships with employers, financial institutions, and wellbeing platforms to broaden reach and impact.

The success of this funding round highlights growing investor interest in purpose-driven fintech — especially products that use psychology and gamification to drive positive outcomes. With early signs of strong user engagement and clear market differentiation, Rule is well-positioned to test whether gamified saving can scale sustainably.

Although its initial focus remains in the UK, the company’s model could easily expand to other markets where younger or neurodiverse users face similar challenges managing money. If Rule can prove retention and impact at scale, it could open a new frontier in how fintech apps merge behavioural design with financial wellbeing.

With £800,000 in new funding from London Venture Partners and Bethnal Green Ventures, Rule now has the momentum to evolve its playful savings experience into a platform that helps users take control of their finances — one virtual squirrel at a time.
