CEO Mirko Lalli says the funding enables the company to "face the challenge of the most mature markets much quicker."
Travel Appeal raised funding of €700,000 last year from three international investors after being originally backed by innovation hub H-FARM with a pre-seed investment of €250,000.
The company has 30 employees and offices in Italy as well as in London and Amsterdam.
