We started with an audit: systematically checking what Google Slides can actually do — from master layouts to chart types, icons and object formatting — and where it falls short compared to PowerPoint. For the build itself, we deliberately took a detour: master and slides were first drafted in PowerPoint, since it allows more precise, faster design work, then imported and adapted in Google Slides. That let us push both tools to their limits instead of being constrained by Google Slides from the start — and deliver the best result actually achievable in Google Slides. Because the CI is brand-defining for A11, this wasn't just about formatting: colors, typography and imagery had to be exactly right so the brand stays recognizable on every slide. We built the slide library itself around A11's actual day-to-day work: the consultancy runs workshops and projects on data-driven growth topics — from sales and marketing to profitability, product and data — so it needed slides for analysis, KPIs, processes and case studies. A11 also presents on big stages and pitches to investors and prospective clients, so the library includes a lot of elements specifically for pitching at events and conferences too — team and company slides, big number statements, reference slides. All told, it's a very extensive library that works across a wide range of presentation situations.
