A presentation maker became an AI sales researcher, then closed the product that made it famous. Tome's story asks a rude but useful question: what if everyone loves the thing you cannot sell?
The PowerPoint challenger’s cleverest idea was not generating more choices. It was removing the bad ones - then selling that constraint as a faster way for teams to think in public.
Slidely AI is a Y Combinator-backed (S22) startup building an AI copilot that lives inside Microsoft PowerPoint. Instead of exporting to a web builder, users generate, redesign, reformat and proofread fully editable slides from a natural-language prompt, and the tool learns a company's existing fonts, colors and layouts so output looks on-brand rather than generic. Founded in 2022 by Apoorve Singhal and Nikhil Shah, the company targets consultants, corporate teams and students who live in PowerPoint and want to cut the time spent formatting decks.
thorntale (YC W24) is a San Francisco software company that built presentation tools for data storytelling. Instead of screenshotting charts from Looker or Snowflake into Google Slides, teams could connect live data sources directly into decks, so charts stayed interactive and up to date - even re-segmentable during a live Q&A. Founded in 2024 by data scientist Dori Wilson with engineers Ellen Hui and John Stimac, the company later pivoted toward an AI-powered presentation editor and shipped a free AI Presentation Review tool before winding the core Presentations product down at the end of 2025.
Prezi is a cloud-based visual communication company best known for inventing the zooming, non-linear presentation - an open-canvas alternative to slide-by-slide decks. Founded in Budapest in 2009 and now dual-headquartered in San Francisco and Budapest, Prezi has grown into a full suite spanning Prezi Present, Prezi Video (presenter-on-screen overlays), Prezi Design/Infograms, and Prezi AI. More than 160 million people have used it to create roughly 400 million presentations.
