Authentix, a US-based provider of banknote authentication and high-speed sensor technology, has raised $15m in its series C round from a consortium including private energy conglomerate Manti.
The other investors included private equity firm Carlyle Group and asset manager JH Whitney. Together, the three firms and company management bought out Authentix in April 2008 after Manti had led the portfolio company’s $14.5m series A round in July 2004.
Since entering the banknote industry in 2006, Authentix has secured contracts with six central banks and helped recover $11bn in lost revenue.
Authentix will use the latest round to expand its technology into sectors including oil and gas, pharmaceuticals, spirits and personal care and buy out peers.
