Novabook is the “Accountant for Startups”. Our team previously founded, scaled and sold a technology company for $50M. We started Novabook to solve the problems we faced during this process. Our aim is to make the financial processes of starting, running and selling a business in the UK easier.

After launching in May 2024, we already have 900+ clients, £3M ARR and are growing quickly, this is an opportunity to join the ride at an early stage. In December 2025 we raised a £7.5M seed funding round to continue our growth.

Software that accounting firms currently run on is extremely outdated & disjointed. This results in a lot of manual work which is costly and error prone. We are building a suite of integrated products to automate 90% of the workflow within accounting firms. We are rapidly scaling our engineering team to facilitate this build out across workflow, payments, open banking, payroll & automated bookkeeping domains

CAiDENN is architecting the world's first Financial Processing Unit (FPU). We are dismantling the $100B legacy ERP market by replacing static "User Seats" with deterministic, zero-error agentic engines.

Born out of the need for institutional-grade precision, CAiDENN manages billions in transaction volume for global leaders like SS&C. We aren't just another "AI Wrapper"; we are a high-fidelity infrastructure layer where probabilistic AI meets the uncompromising math of a .NET 10 hardened core.

We are currently recruiting our "Elite 3"—a founding squad of veteran architects and high-signal unicorns. We move at 10x speed using AI-native multipliers (Claude Code, Lovable, Cursor) to out-produce legacy firms. At CAiDENN, we don't build software to help people work; we build engines that own the outcome.

To be the leading global platform that seamlessly connects people to personalised financial and wellbeing support, empowering them to improve their financial health and thrive.
