Zetwerk, a business-to-business manufacturing services startup, is in talks to raise $100-125 million in a funding round, valuing the company a notch higher than its last valuation of $2.7 billion, three people with knowledge of the development said.

The company has held talks with funds such as Premji Invest, TCV Partners and Catamaran, the people said, requesting anonymity. The round will be entirely primary fundraising, with the company’s existing investors also topping up, they added. A spokesperson for Zetwerk denied the development. Emailed queries to spokespeople for TCV, Premji Invest and Catamaran, did not elicit any response.

In December, Zetwerk raised its Series F funding round of $200 million from investors led by D1 Capital and Greenoaks, valuing it at $2.7 billion. The four-year-old company’s previous $150 million funding round helped it enter the unicorn club, or startups that are valued at more than a billion dollars.
