London-based venture capital firm Nauta Capital has completed with 55 million euros ($61.8 million) in funding for its fund dedicated to backing its existing later-stage portfolio companies.

The new later-stage fund, called Sidecar Fund, brings Nauta’s total assets under management to $409.7 million.

With the funds raised, Nauta Capital will invest in follow on capital, primarily from Series C in its portfolio as the firms mature for later-stage funding.

The new fund is backed by current investors from continental Europe, UK and the Americas, including the British Patient Capital among others.
