About Us

Most presentation tools solve the same problem: helping you build a deck. slideAcross solves a harder one: what happens when you're standing in front of the room and the conversation goes somewhere you didn't plan for.

Built around layered storytelling, slideAcross lets presenters switch between content formats live, based on how the room is responding. No quiet disengagement, no complaints that the material lacked depth, nobody left behind because of learning preferences.

When a question catches you off guard, on-demand slide generation creates new slides in real time from trusted documents and data already in your content library. The conversation keeps moving, and you never have to promise to follow up with something you should have had ready.

Voice controls keep your attention on the audience, not the keyboard. Integrated conferencing brings live demos, product walkthroughs, and webinars into the presentation itself, with no tab-switching or context loss.

AI-driven slide creation and a full suite of design tools make preparation faster too. But that's not what sets slideAcross apart.

Built for sales teams, business leaders, educators, consultants, and enablement teams who want their presenters walking into every room with an unfair advantage. If your presentations are conversations, not performances, slideAcross was built for you.

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 an innovative and fast-growing 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.
