Roaring alternative

Roaring is a Nordic risk and compliance data platform with APIs, and for most of what it does it is broader than we are. This is the honest split, for teams looking up Swedish companies from code.

TL;DR

Roaring is a Swedish company (Roaring Group AB) that describes itself as giving organisations trusted insight into businesses, individuals and their relationships, built on Nordic data quality. It sells to banks, insurers, the public sector and other companies for onboarding, compliance, authorised-signatory checks and supplier audits, through REST-based APIs, webhooks, a Flow Builder, a sandbox and an in-app product called Roaring Lookup. Everything on this page about Roaring was read on its own sites (roaring.io and developer.roaring.io) on 2026-09-30; nothing comes from a third party.

Prometiam is the register-record API. You hand it an organisationsnummer, a Swedish VAT number or a few typed letters and get the Bolagsverket record back in the same response shape as every other live country. If you need board members, financials, ownership, PEP or sanctions data on Swedish companies, Roaring is the better tool and we are not a substitute. If you need the official record of a Swedish counterparty at a price you can see, starting without a sales conversation, we are the leaner fit.

Where Roaring is genuinely ahead

1. Breadth of data. Its data page lists company information and financial information, board members and board assignments, authorised signatories, ownership and group structure, beneficial owners, PEP, sanctions lists, adverse media, credit ratings and risk indicators, among others. The Swedish record on Prometiam is the register record plus filed financial statements (digitally filed (iXBRL) accounts only, on the Scale plan and above).
2. Nordic reach. Its data page filters by Sweden, Norway, Denmark and Finland. It also lists Spain and a global set. Check Prometiam's coverage list against the countries you need before you assume parity.
3. Officers, signatories and ownership. Board members, authorised signatories and beneficial owners are datasets on its data page. Prometiam serves none of them for Sweden.
4. Monitoring and automation. Webhooks that notify you when monitored datasets change, a Flow Builder for building and exporting workflows, and monitoring inside its Lookup product. Monitoring on Prometiam is every live country except France and Chile.
5. Compliance depth. Screening datasets (PEP, sanctions lists, adverse media) and ready-made use cases for KYC, AML and supplier audits, aimed at regulated buyers in banking, finance, insurance and the public sector.

Where Prometiam is ahead

1. You can see the price, and start on it. Prometiam publishes every tier: a 14-day trial, then €9.99 to €99.99 a month, monthly or annual, each with its call allowance and rate limit. Roaring's pricing page lists a free sandbox, a paid plan for its integrations with usage charges added on top, and a custom plan.
2. The official record, validated. An organisationsnummer is checked against its Luhn digit and the third-digit rule before you spend a call, and the Swedish VAT number resolves to the same company. Status and dates come from the register itself, and a company it flags as bankrupt, in liquidation, in restructuring or in administration is not served as plain active.
3. One schema across the registries. The same response shape for Sweden as for every other registry the API covers; adding a market is a country value, not a second integration.
4. Built for a lookup. One bearer key, one parameter per identifier, a name search made for a form field, and free lookup tools you can try without a key.
5. No annual commitment. Monthly is the default and neither billing option has a minimum term.

Built for the API-native workflow

Roaring is built around risk and compliance decisions on Nordic companies and people. If your workflow is a lookup instead — resolving a customer's identifier, or a few typed letters, into a company record for an onboarding form, an invoice or a CRM row — this is what that looks like on Prometiam:

• Every identifier, one parameter. NIF/CIF, SIREN or SIRET, the Companies House number, the CRO number, the KRS number, the organisasjonsnummer, the Y-tunnus, the organisationsnummer and each other registry's own number all go in the same parameter — ?country= picks the register, the parameter doesn't change. Prometiam takes the register's 556012-5790, with or without the hyphen, and the VAT form SE556012579001 through vat=.
• Name search built for a form field. ?name= is a normalised, partial match — call it on every keystroke and wire it into a type-ahead.
• One schema, every registry. The same response shape for every ?country= value.
• Auth and rate limits. A single bearer key (Authorization: Bearer rk_live_...) issued at signup; limits scale 10 to 600 requests/minute by tier.
• A typed client, if you want one. prometiam-risk-api on npm — TypeScript types, retries on 429/5xx, cursor pagination, typed errors. The same client for Python: prometiam-risk-api on PyPI.
• From an agent, not just a form. The MCP server (prometiam-risk-mcp on npm) puts the same lookups in Claude Desktop, Cursor or any MCP client.
• Public pricing, monthly or annual. Every tier is published; paying yearly is ten months' price for twelve. Starter begins with a 14-day trial: 500 credits, 10 requests/minute, card required, nothing charged for 14 days. Subscribing keeps the same key working. The trial is not an ongoing plan.
• Try an identifier before signing up. Free organisationsnummer (also as a Swedish-language search), Y-tunnus, NIF, SIREN, Companies House number, KRS, CRO number and organisasjonsnummer lookup tools run the same call with a shared key. Roaring's pricing page lists free access to a sandbox for building before you pay.

At a glance

Which to choose

Choose Roaring if you are a bank, insurer, public body or compliance team that needs board members, authorised signatories, ownership, beneficial owners, PEP, sanctions or adverse-media data on Swedish and other Nordic companies, want monitoring through webhooks, or need the ready-made KYC, AML and supplier-audit flows.

Choose Prometiam if you are building onboarding, invoicing or KYB flows that need the official record of a counterparty by organisationsnummer, VAT number or name, the same response shape across several countries, and a published price you can start on without a sales call.

The two also combine: Roaring for the wider Nordic risk and compliance datasets, Prometiam for the register record and one schema across the other live countries.

FAQ

Is Roaring an API-native Swedish company data provider?
Yes. It publishes REST-based APIs, webhooks for monitored datasets, a Flow Builder and a sandbox on a developer portal, and its data page filters datasets by Sweden, Norway, Denmark and Finland. It also lists Spain and a global set.

What does Roaring cost?
Its pricing page lists a free sandbox, a paid plan for its integrations with usage charges added on top of a monthly fee, and a custom plan; its Lookup product is priced the same way. Prometiam publishes every tier, starting with a 14-day trial with a card required and nothing charged for 14 days.

Can I try the Roaring API for free?
Its pricing page lists free access to a sandbox. A Prometiam key is issued at signup with nothing charged for 14 days, and the free lookup tools run the same call without a key.

Does Prometiam have Swedish officers, financials, PEP or beneficial owners?
Only in part. Sweden is company-level, with register-change events and monitoring, but no officers and no registry-compliance signal (corporate insolvency notices are linked by organisationsnummer). Financial statements are returned for digitally filed (iXBRL) accounts only, on the Scale plan and above. For board members, wider financial data, ownership, PEP or sanctions data on Swedish companies, Roaring is the better tool.

Can I use both?
Yes, and many teams should: Roaring for the wider Nordic risk and compliance datasets, Prometiam for the register record, organisationsnummer and VAT validation and one schema across the other live countries.
