The startup has raised another $100 million in funding, money that it plans to use to build out its AI algorithms and expand deeper into international markets. Hopper has now passed 30 million installs and 75 million trips planned, and says it's on track to make nearly $1 billion in sales this year. Sources very close to the company say Hopper's valuation with this round is also flying: it's now close to 1 billion Canadian dollars ($780 million in US dollars). As a point of comparison, Hopper was valued at US$300 million in its last round, in late 2016, and it has raised C$184 million (US$235 million) to date. Throughout that time, it's been a consistent presence in the top-10 travel apps in the US, according to stats from App Annie.
