About Us

slideAcross is a powerful tool for professionals who need to deliver engaging, adaptable presentations that respond to audience interest in real time. Traditional slide decks often follow a rigid, linear structure, limiting the ability to adjust to evolving conversations. With slideAcross, presenters can layer slides beneath key points, enabling seamless exploration of deeper insights, supporting data, or additional context whenever required..

slideAcross is a trading name of Affirmable Limited - you can find more details about Affirmable below and through the Affirmable website.

Introducing Affirmable Limited

Affirmable was founded by Martin Tanner in 2024 as a small and agile technology development company. We are based in the UK and primarily develop and sell our own products (apps and webapps).

Two of these products (Datacase and slideAcross) are aimed at business customers.

A further two of these products (iBudge and iThankUK) are aimed at consumers.

We also deliver a range of consultancy and technology design services to customers. These typically draw on Martin's experience, both in the software and app/web-app design space and in his previous career in data, solution design and bid management. Martin spent nearly 20 years working at a senior level across recruitment and welfare-to-work and many of his professional insights draw on this expertise.

We are a values-driven company and are committed to investing in community and inclusion. Many of our products and services include a substantial discount for charities and non-profit organisations. Please contact us for more information.
