Backend Engineer, Tessian

However, sophisticated cyber attacks are becoming more common, with cybercriminals impersonating colleagues, customers or suppliers in targeted attacks that are difficult for people to detect. Tessian’s technology detects when an email represents a threat, reducing the chance of human error.

The problem is real for all company sizes. Hiscox, a big insurer, reported that small businesses in the UK are targeted with 65,000 attacks per day. Those suffering from incidents are facing costs of ~£25k.

There aren't many other companies that have rocketed as much as Tessian in the last couple of years. It started out slow, but has grown rapidly since its $2.7m seed round in 2017 (which was quickly followed by a $13m round in 2018, a $42m round in 2019 and a $65m round in 2021). The company has focused on accelerating expansion across the North American Market and is well set to see continued success in the market.
