Among the strategic investors are: entrepeneur Carmen Busquets, former Net-a-Porter chief executive Mark Sebba, and venture capitalist Pat Finn.
Flowerbx delivers direct from the auctions in Holland. Investment funds have been allocated to improve website technology and user experience, enhance distribution and logistics capabilities, and to execute strategic hires.
Sebba said: "I am delighted to be an early investor in FLOWERBX. It has a lean business model, and, as a Flowerbx board member, I look forward to helping the brand achieve its enormous growth potential."
Busquets added: "The Flowerbx team understands the importance of building a strong brand. I have been a loyal client since day one as I know I can trust the reliability of the delivery, the freshness of the flowers and the quality of the presentation."
Finn said: "The Flowerbx team impressed me from our first meeting, as it is a founding team with a diverse set of experiences and a myopic focus on execution. They have built a passionate and loyal group of advocates and consumers due to the high quality of their product and their clearly articulated brand vision. It is exceedingly unusual to see these components come together so early in the lifespan of a company."
Flowerbx was co-founded by Adam Wilkie and Whitney Bromberg Hawkings in April 2015.
