US-based beverage company Rowdy Mermaid Kombucha has completed the second and final tranche of its Series A investment round.

In the latest financing round, the company raised additional capital of $3.5m, which will be used by the company to support its investments into sales and marketing and continued national expansion, as well as the introduction of an e-commerce platform.

Rowdy Mermaid Kombucha founder and CEO Jamba Dunn said: “The past year has been an exciting time for all of us at Rowdy Mermaid as we further expand our national footprint and bring new flavours and functions to our product line.

“As we continue to dream up new ways to introduce functional beverages to as many people as possible, partners like KarpReilly help us achieve our goal of plant-based medicine from Rowdy in every fridge.”

Until now, the company is said to have raised total gross proceeds of $7m.

This year, the kombucha beverage maker expects a triple-digit sales growth as the beverage manufacturer expands into new markets.

The funding round was led by KarpReilly, a Greenwich-based private investment firm, which hold a portfolio of emerging brands in the consumer sector.

KarpReilly portfolio includes notable food, beverage and natural products such as Spindrift, LIFEAID, KeVita, Koia and ICONIC Protein.

KarpReilly co-founder Allan Karp said: “Year after year, we continue to see innovative products, initiatives and solutions from our friends at Rowdy Mermaid.

“Rowdy’s function-forward flavours, approachable brand, and unwavering passion for product integrity are the key points of difference in an otherwise crowded category.”

Last February, Rowdy Mermaid Kombucha announced the completion of its Series A funding round.
