How much has Calcarea raised in total?
$3.5M reported by PitchBook is the best disclosed total used in this profile. It includes $3.5M reported Seed/early funding.
Because private-company databases can disagree, this profile prioritizes company announcements, investor posts, and named press releases over opaque estimates.
Who are Calcarea's investors?
Named backers include AltaSea, Azolla Ventures, Caltech, Kibo Invest, LomarLabs, and other reported early investors. These investors are relevant because they bring climate, industrial, software, infrastructure, or strategic-market experience to the company.
Why did the valuation move or remain undisclosed?
Valuation has not been publicly confirmed, so movement should be inferred only from round size, strategic investors, commercial traction, and technical milestones. Hardware and climate-infrastructure companies often disclose capital and offtake before they disclose price-per-share valuation.
Is Calcarea profitable, and will it IPO?
Calcarea has not disclosed profitability or IPO timing. The nearer-term milestone is commercialization, deployments, and repeatable unit economics rather than a public listing.
What does Calcarea's funding mean if you sell into them?
The funding supports prototype development, ship-integration partnerships, MRV work, and commercial maritime pilots. Sellers should map outreach to ship owners, fleet operators, naval architects, maritime fuel and compliance teams, sustainability leaders, and carbon-credit buyers, with proof points around reliability, compliance, implementation speed, and measurable climate or operating impact.
