Island Announces $400 Million Series F, Bringing Valuation to $6.4 Billion

This is the page you're already on — the Human View toggle above shows it in full.

A green key on the record, left, is one Decision Insights added. It doesn't exist on the company's site or in a wire feed. The same key labels its row on the right, so you can match them directly. More on how DI enriches a record.

What we add

Audience targeting

A company states its own audience in marketing copy, if at all. This is Decision Insights' own classification of the content -- seniority, job function, buyer role, adoption curve, technology maturity and target industry -- not the publisher's self-reported audience.

Seniority EVP / SVP / VP / AVP Job function Chief Information Security Officer Persona Security Architect Buyer role Decision Maker / Budget Holder Adoption curve Early Majority Technology maturity Operational Expansion Industry Information Technology / Cybersecurity / Exposure, Risk & Governance / Security Awareness Training & Human Risk Management

Subject determination

A syndication feed carries a story and every company it happens to name, with no way to tell which one the story is actually about. This is Decision Insights' own determination of this article's subject -- one company, resolved from the source feed's own assignment where one exists, our own analysis otherwise.

Island.io https://decisioninsights.ai/registry/island/

Entity resolution

A wire feed names a company as a bare string, mentioned once and never resolved to anything. This is every company and project Decision Insights identified in this article, each linked to its own record with a real address, not a name an agent has to match itself.

CNBC https://decisioninsights.ai/registry/xfinity/cnbc/ CrowdStrike https://decisioninsights.ai/registry/crowdstrike/ Island.io https://decisioninsights.ai/registry/island/ and 2 more

Primary source

Our own summary carries our own byline, same as anyone else's would. This is the original work it is based on -- the source URL, its author and its publisher -- so the claim can be checked against where it actually came from, not just taken on our word.
