Event types | Evinor

Last updated July 9, 2026

Detection difficulty is not uniform across Event types. Every type below carries a maturity chip: Established types have tight, well-bounded detection criteria; Emerging types are noisier to detect. That difference is exactly what the confidence band is for — gate on it, and gate harder on the Emerging types.

Wire contract: protocolVersion 0.1. We intend Event type codeNames to be stable, and we treat renaming one as a breaking change. Role codeNames may still change before 1.0 — read them defensively and skip codes you do not recognize. The envelope that wraps all of this is documented on Event delivery.

roles is a list, not a map. The same code may appear more than once: a round backed by three investors arrives as three INVESTING_COMPANY_NAME entries. Roles that can repeat are tagged repeatable in the tables below. Do not key by code — Object.fromEntries(roles.map(r => [r.code, r.textValue])) keeps the last entry and silently discards the others. Group by code instead.

Each role table below has a Typecolumn — the role’s value type, and which parsed companion it carries on the wire:

NAMED_ENTITY: An organization or person named in the Event. Carries namedEntityId when the text resolved to a known entity.
CURRENCY: A monetary amount. Carries a parsed parsedAmount; a role that does not parse is dropped rather than delivered unparsed.
NUMBER: A plain count or percentage. Carries a parsed parsedAmount, the same guarantee as CURRENCY.
DURATION: A span of time, validated as text. May carry parsedAmount, but only sometimes.
CATEGORICAL: One value from a fixed vocabulary, delivered as an uppercase token in textValue. No parsed companion.
NONE: Free text with no parsing — the value is in textValue only.

05IPO

IPOEstablished

A company makes a concrete move toward going public: an exchange filing, a priced offering, or a first day of trading. A filing alone counts, so this Event can arrive long before any share changes hands.

Role code	Name	Type	Description
`COMPANY_NAME`	Company Name	`NAMED_ENTITY`	The business seeking or completing a public listing.
`VALUATION`	Valuation	`CURRENCY`	What the company is valued at for the offering. On a filing this is a target or an expectation, not a settled market price.
`AMOUNT_RAISED`	Amount Raised	`CURRENCY`	How much capital the share sale brings in. Sought or projected until the offering actually prices.
`STOCK_EXCHANGE`	Stock Exchange	`NONE`	The exchange named for the listing, such as NYSE. It can be announced before anything trades there.

07Product Launch

PRODUCT_LAUNCHEmerging

A company introduces a product, adds a major new feature, ships a new version, expands what an existing product can do, debuts creative work, or opens a product to a wider audience.

Emerging — noisier to detect; we recommend gating on confidence.band = HIGH.

Role code	Name	Type	Description
`COMPANY_NAME`	Company Name	`NAMED_ENTITY`	The organization behind the launch.
`PRODUCT_OR_SERVICE_NAME`	Product or Service Name	`NAMED_ENTITY`	The product or service being introduced.
`LAUNCH_TYPE`	Launch Type	`CATEGORICAL`	Which kind of launch this was, delivered as an uppercase token drawn from a fixed vocabulary rather than free text.
`HOST_PRODUCT`	Host Product	`NAMED_ENTITY`	The existing product that a newly added feature or capability plugs into. Absent when the launch stands on its own.
`COMPANY_SHORT_DESCRIPTION`	Company Short Description	`NONE`	A brief phrase describing what the company does.
`PRODUCT_DESCRIPTION`	Product Description	`NONE`	A brief phrase describing what the product does.

PRODUCT_LAUNCH — roles on the wire

{
  "eventCodeName": "PRODUCT_LAUNCH",
  "details": {
    "roles": [
      {
        "code": "COMPANY_NAME",
        "textValue": "…",
        "namedEntityId": "…"
      },
      {
        "code": "PRODUCT_OR_SERVICE_NAME",
        "textValue": "…",
        "namedEntityId": "…"
      },
      {
        "code": "LAUNCH_TYPE",
        "textValue": "…"
      },
      {
        "code": "HOST_PRODUCT",
        "textValue": "…",
        "namedEntityId": "…"
      },
      {
        "code": "COMPANY_SHORT_DESCRIPTION",
        "textValue": "…"
      },
      {
        "code": "PRODUCT_DESCRIPTION",
        "textValue": "…"
      }
    ]
  }
}

In the samples above, … marks an elided value and any number is illustrative, not real data. namedEntityId, parsedAmount and parsedDate are all optional companions to textValue — present only when entity resolution or value parsing succeeded. parsedAmount appears whenever we parsed a numeric amount. It is guaranteed on the numeric and measurement types (CURRENCY and NUMBER among the roles above), because such a role is dropped rather than delivered unparsed. It may also arrive on a DURATION role, which is validated as text and so carries an amount only sometimes — the samples above do not show that case. A role that was not extracted is absent from roles entirely, never present with a null value.
