Panthalassa Funding: Rounds, Investors and Valuation

Introduction

Panthalassa is developing ocean-energy and offshore computing systems. The clearest public financing record is its Series B announcement. The amount, lead investor, named participants, and use of proceeds below follow that announcement; figures from databases are labeled separately.

Evidence boundary: a media report placing the company near a $1 billion valuation is not the same as a company-disclosed valuation. It is included only as reported context.

2. Review and export. Check that financing amounts, valuation estimates, and database totals remain separate before exporting.

Collect source-backed Panthalassa funding information. Prioritize company announcements and reputable reporting. For each round capture round_name, amount, announcement_date, lead_investors, other_named_investors, use_of_proceeds, source_url, and evidence_scope. Separate company-disclosed amounts from database estimates and media-reported valuation. Do not infer an undisclosed valuation or combine database totals as an official figure.
