Finnish startup MariaDB raises a $104M Series D and plans for an IPO on the NYSE via a SPAC merger
Finland's MariaDB has closed a $104 million Series D private placement round and announced its intention to become a publicly-traded entity on the New York Stock Exchange via a merger … Source: Business Wire .
Context & Ripple Effects
This closes the loop on MariaDB's private-market climb: an Alibaba-led round at a $354M valuation in 2017, then a $25M Series C extension in 2020 that the company said doubled that mark, and now a $104M Series D private placement that sets a ~$672M valuation as the reference price for the public listing.
The notable structural choice is the route: rather than a traditional IPO, MariaDB is merging with a SPAC to reach the NYSE — a faster path to US public markets for a European open-source database company, but one where the ~$672M target becomes the number every later trade and offer is measured against.
First-order effects
- MariaDB's existing backers — including the Alibaba-led syndicate from 2017 — now hold stakes marked against a ~$672M valuation, roughly double the level set by the 2020 Series C extension.
- The SPAC merger hands the company a NYSE listing and public currency without a conventional IPO roadshow, with the Series D private placement pre-funding the transition.
Second-order effects
- The listing makes MariaDB one of the few pure-play open-source database companies trading in the US, forcing competitors and customers to price its roadmap against a public market cap rather than private round marks.
- A ~$672M public valuation becomes the benchmark for European open-source infrastructure peers weighing US listings — but if the stock trades below the SPAC target, as later coverage shows it did in a debut that closed down 39.6%, the template inverts into a cautionary mark.
Third-order effects
- MariaDB's full arc — SPAC listing at a ~$672M target, then a $37M K1 take-private offer and eventual acquisition and NYSE delisting — points to SPAC-route valuations for open-source infrastructure being systematically reset by public markets, with private equity as the clearing mechanism.
- If the pattern holds, European open-source companies will keep using SPACs for US market access while treating the public listing as a transitional state rather than a destination, with take-privates absorbing the ones whose public valuations detach from private marks.
The trend: European open-source infrastructure companies are using SPAC mergers to reach US public markets, but public-market pricing is resetting their private valuations downward and pushing the losers into private-equity take-privates.
