Blis Technologies has reported a positive first half of the financial year, with a 25% increase in revenue to $6 million.

The company's B2B and B2C sales channels both contributed to the growth.

Blis' unaudited net surplus for the period was $200,000, compared to a loss of $700,000 in the same period last year.

The company also achieved ebitda of $300,000, compared to a loss of $600,000 in the previous year.

However, Blis expressed concern over a key customer filing a patent for its BLIS K12 and BLIS M18 fermentation process in three key jurisdictions.

The company is currently in negotiations with the customer and has sought legal advice.

Blis Technologies is a manufacturer of advanced probiotic strains, with products sold in New Zealand and internationally.
