Ideogram

Ideogram is a Toronto-founded generative AI company whose text-to-image models are known for rendering readable typography inside generated images.

About

Ideogram was founded in 2022 by Mohammad Norouzi, Jonathan Ho, William Chan and Chitwan Saharia, four researchers who had worked together on Imagen, Google's text-to-image system. Norouzi spent seven years at Google, part of it in Geoffrey Hinton's group in Toronto, and told a TechTO fireside in July 2024 that the team saw the potential of diffusion models early — Ho wrote the first diffusion paper while at UC Berkeley — but that turning the research into a product was hard to do inside a large company. The company describes itself as a visual communication platform rather than an image generator: users write a prompt and get images back, with the models trained in-house. Ideogram announced a US$16.5-million seed in August 2023, then an US$80-million Series A led by Andreessen Horowitz in February 2024, alongside the release of Ideogram 1.0. On stage in Toronto, Norouzi opened by saying the company had not yet built a successful business and was not profitable, and asked the audience to weigh his advice accordingly.

Backers

Andreessen Horowitz led the US$80-million Series A, with Index Ventures returning and Redpoint Ventures, Pear VC and SV Angel participating. Index Ventures backed the earlier US$16.5-million seed.
