Our take
The drive towards data-driven business decision making, coupled with the rising complexity of data infrastructure has led to huge amounts of capital investment into Data Observability companies.
Coralogix is one such company – along with the likes of Crible and Monte-Carlo – to have secured hundreds of millions in funding as they look to get ahead of the competition. Each offers solutions that ensure the integrity and quality of data, but Coralogix sets itself apart by not requiring manual indexing from engineers.
The knock on effect of this model is that engineers can make faster queries, while large-scale data systems are able to grow without burdening engineers with manual tasks.
Though founded in Israel in 2014, Coralogix has been scaling aggressively since 2019, opening a second HQ in California and offices in India and the UK. Considering the health of the Data Observability market as well as its heavy funding, Coralogix looks well positioned for further growth, especially off the back of 2025 funding.
