Making sole trader tax heavenly.

TaxHeaven is a FinTech B2C SaaS app designed to simplify Self Assessment tax returns for UK sole traders and freelancers by combining frictionless UX and multimodal AI models.

Onboarding process

Began as a personal project to gain more hands-on experience with agentic workflows and tuning and training of LLM/multimodal models, but evolved into a product that I am building in public as it seemed to resonate with a lot of people.

Leading all aspects of the business in taking the product from 0→1:

Product & Design: Defining the product vision and roadmap. Designing a simple, frictionless user experience to make tax management more accessible.
Full-Stack Development: Architecting and building the complete technical solution. This includes frontend (Figma, Lovable), backend (Supabase with PostgreSQL, Auth, Edge Functions) and integrating key APIs for payments, AI models, product analytics, marketing and transactional automation.

Early feedback from first users

Currently building in public and working with our first wave of 'founding angel' users to create the best possible tool for the UK's self-employed community.
