Jonaz B.V.
About Jonaz B.V.
Jonaz B.V. is a Dutch private limited company (besloten vennootschap, B.V.) registered in the Handelsregister of the Netherlands Chamber of Commerce (KvK) under number 24403213, with its address at Stationsplein 45 (unit A5.002), 3013 AK Rotterdam. Its registry status is recorded as active. Jonaz B.V. is a retail telecommunications provider: under the Jonaz brand it sells fibre internet access, television and fixed telephony to households in the Netherlands.
The company’s regulatory identity is confirmed by the Netherlands Authority for Consumers and Markets (ACM). The ACM register of telecoms providers and postal carriers records KvK number 24403213 as Jonaz B.V., Rotterdam, registered on 23 September 2014 in the category aanbieder van een openbare elektronische communicatiedienst — provider of a public electronic communications service. The same register does not record Jonaz B.V. as a provider of a public electronic communications network, which matches the way the company describes itself: it resells connectivity over fibre infrastructure operated by others rather than owning the access network.
Jonaz sells only over fibre, not DSL or coax. Its published consumer proposition is a symmetrical 1,000 Mbit/s connection at EUR 39.95 per month, with an optional television package at EUR 4.95 per month and fixed telephony sold separately; customers receive a Wi-Fi 6 router on loan and installation at home. The company’s site lists coverage in Amersfoort, Almere, Baarn, Gooise Meren, Hilversum, Lelystad, Leusden, Nijkerk, Soest and Veenendaal. A press item on the same site records a network extension of roughly 20,000 addresses in Nijkerk, Nijkerkerveen and Hoevelaken in the second week of June 2023, and the launch of a fibre price guarantee on 1 May.
Jonaz B.V. appears by name in three Dutch official publications. The ACM’s market study into the roll-out of fibre in the Netherlands (31 October 2019) names Jonaz among the service providers active on Dutch fibre networks. A Ministry of Economic Affairs and Climate Policy study on free modem choice (February 2019) lists Jonaz, with its seat given as Rotterdam, as a member of the trade association NLconnect. Annex 3 to the Convenant Blokkeren Websites — the website-blocking covenant between Stichting Brein, Ziggo, KPN, T-Mobile, DELTA Fiber, Canal+ and NLconnect — names Jonaz BV as one of the internet access providers that mandated NLconnect to sign on their behalf.
No entity-level revenue or employee figure could be verified. A Dutch B.V. files annual accounts with KvK, but the filed accounts are a paid product and no free source publishes them.
Registration date
The stored incorporation date of 1 January 2024 is a placeholder, not a filed date. It is contradicted by the record: the ACM register shows Jonaz B.V. already registered as a telecoms provider on 23 September 2014, and the Internet Archive holds a Jonaz B.V. terms-and-conditions PDF uploaded to the company’s own site in September 2014. The company’s About page says the business was set up in 2015, which its own 2014 documents do not support. GLEIF holds no LEI for KvK 24403213, so no registry-validated creation date is available. A sweep of GLEIF records for the 500 KvK numbers either side of 24403213 returned 20 KvK-validated creation dates, 19 of which fall between 15 October and 26 December 2006 (one outlier in 1997); the sequence is clustered but not strictly monotonic. That dates the block of register numbers, not the company, so no incorporation date is stated here.
Legal form shown on the company card
The company card on this page labels Jonaz B.V. a “Private limited company (Ltd.)”. That is a generic translation carried in the stored data, not the entity’s legal form. Jonaz B.V. is a Dutch besloten vennootschap met beperkte aansprakelijkheid (B.V.); “Ltd.” is a British and Irish company form with no application in the Netherlands. Every source checked — the ACM register of telecoms providers, the privacy statement on the company’s own site and the audited subsidiary list of its parent — gives the name as Jonaz B.V. The stored registry status of Active is consistent with those sources but is not in itself evidence that the company is currently trading.

Shareholders
Shareholders of Jonaz B.V.
No shareholder rows are held for Jonaz B.V. The provider returned its standard "no data" response for the Netherlands rather than a list, so the company profile carries zero shareholder records. That is an absence of data, not evidence that the company has no shareholders.
One ownership figure is nonetheless on the public record, from the audited consolidated financial statements of Nuts Topholding B.V. (KvK 68242050, Amsterdam), published on the group’s own website and reported on by KPMG. Its list of subsidiaries states a share in issued capital of Jonaz B.V. of 50.05% at 31 December 2024 and again at 31 December 2025. This is the interest held by the Nuts group as a whole, reported at group level; the statements do not identify the entity that holds the shares directly, and they do not name the holder of the balance. The 2024 statements record a non-controlling interest of EUR 3,998 thousand recognised on acquisition, measured against the 49.98% held by other shareholders in the intermediate holding company, and describe those other shareholders only as "the founders of the underlying entities".
The stored profile shows no shareholder percentages of its own, so no reconciliation against an issued share count was possible and none is published here.
Ultimate beneficial ownership
No ultimate beneficial owner of Jonaz B.V. could be identified from any source reached. The Dutch UBO register has been closed to the general public since the Court of Justice of the European Union’s ruling of 22 November 2022, and the ownership chain available from the group’s financial statements stops at corporate entities and an unnamed group of founders. No natural person is named here, and no effective percentage has been calculated, because part of the chain is missing.
Data availability
Partial. The Dutch Handelsregister does not publish a general shareholder list for a B.V., and the UBO register is not publicly accessible. The only ownership figure obtainable free of charge is the group-level 50.05% reported in the parent’s published consolidated accounts; the identity of Jonaz B.V.’s direct shareholders and of any beneficial owner could not be established.

Officers
1
Directors and officers of Jonaz B.V.
One officer record is held for Jonaz B.V. and the provider reports it as the complete set (one row of one result). It names H.K. Tanis, role given as Director, work status ACTIVE, country NL. No appointment date, no resignation date, no nationality and no role-specific detail accompany it, and no former or resigned officer is recorded.
This record could not be independently verified. The Dutch Handelsregister records the statutory directors of a B.V. and their powers of representation, but publishes them only in a chargeable extract; KvK’s own search is not usable by automated request. No free official source reached names the directors of Jonaz B.V., so neither the accuracy of the single stored row nor the total number of statutory directors in office could be established. Because the record carries no appointment date, it is also impossible to say how old it is.
Two weaker corroborations exist for the surname but not for any directorship. The RIPE NCC database registers Jonaz’s IPv4 allocations (netname JONAZ, described as "Jonaz FTTH customers") under a maintainer whose administrative contact carries the same surname at a jonaz.nl address and a Rotterdam postal address. The company’s own About page states that the business was set up by two brothers. Neither is a register entry and neither establishes who holds a statutory appointment, so nothing further is asserted here.
Data availability
Restricted. Nationality is not disclosed for the stored officer, and the Dutch Handelsregister does not publish the nationality of directors in any free view. Director identities, appointment dates and representation powers exist in the register but sit behind a paid extract, so appointment history, role wording and completeness could not be checked. No conclusion should be drawn from the fact that only one officer is recorded.

Group Structure
Group structure of Jonaz B.V.
Jonaz B.V. is not an independent company. It is a consolidated subsidiary of the Dutch energy and telecoms group headed by Nuts Topholding B.V. (KvK 68242050, registered office Reguliersdwarsstraat 58A, Amsterdam, incorporated 7 March 2017), and it is named in that company’s audited IFRS consolidated financial statements for both 2024 and 2025 as "Jonaz B.V., Rotterdam, 50.05%". Those statements also state that the group obtained control of the intermediate holding company on 8 November 2024 and that the business of that holding "is executed by the operational entities Ipronto B.V., Jonaz B.V. and Spokkie B.V." — which places Jonaz B.V. as one of three operating companies under a single fibre holding, exactly as the stored corporate tree does.
Three of the tree’s Dutch nodes were independently confirmed against the ACM register of telecoms providers by registration number: Jonaz B.V. (24403213), Ipronto Communications B.V. (24391901) and the intermediate holding (95451358), all seated in Rotterdam. The apex was confirmed by KvK number from the parent’s own accounts. The intermediate steps shown in the stored tree between Nuts Topholding B.V. and the fibre holding are consistent with the parent’s subsidiary list but are not set out chain by chain in it, so they are reported below as group companies rather than as a verified ownership path.
Verified corporate relationships
| Entity | Country | Registration number | Relationship | Ownership | Status | Information date |
|---|---|---|---|---|---|---|
| Nuts Topholding B.V. | NL | 68242050 (KvK) | Ultimate parent; consolidating entity | 50.05% of Jonaz’s issued capital, held by the group | Active | 31 Dec 2025 |
| Fiber Crew B.V. | NL | 95451358 (KvK) | Immediate holding of the fibre operating companies | 50.02% held by the group at 31 Dec 2025 | Registered with ACM 18 Sep 2026 | 31 Dec 2025 |
| Ipronto Communications B.V. | NL | 24391901 (KvK) | Sister company; operational entity of the same holding | 50.05% group share in issued capital | Registered with ACM 30 Mar 2021 | 31 Dec 2025 |
| Spokkie B.V. | NL | 23092732 (KvK) | Sister company; operational entity of the same holding | 50.05% group share in issued capital | Not in the ACM register | 31 Dec 2025 |
| Nuts Holding B.V. | NL | 68245386 (KvK) | Group company between the apex and the operating tier | 100% group share in issued capital | Active | 31 Dec 2025 |
| Nuts Groep B.V. | NL | 54036682 (KvK) | Group company between the apex and the operating tier | 100% group share in issued capital | Active | 31 Dec 2025 |
The percentages are the "share in issued capital" figures published by the parent; they are group interests, not the holdings of any one named shareholder. The Netherlands does not publish a share register, so no direct holder of Jonaz B.V.’s shares is named.
Recent structural changes
- 8 November 2024 — Nuts Topholding B.V. obtained control of the newly established fibre holding, taking 50.02%, with the remaining 49.98% held by the founders of the underlying entities. Jonaz B.V. was named as one of the three operational entities acquired with it. Goodwill of EUR 2,632 thousand and a non-controlling interest of EUR 3,998 thousand were recognised across the 2024 acquisitions. Source: Nuts Topholding B.V. Annual report 2024, note 7(c).
- April 2026 — the group completed the purchase of the remaining 49.98% of the fibre holding and now holds 100% of its issued share capital. The parent reports this as a non-adjusting subsequent event with no change of consolidation status; it is not stated what, if anything, it changes in the 50.05% reported for Jonaz B.V. itself. Source: Nuts Topholding B.V. Annual Report 2025, note 29.
- 30 March 2017 — the ACM decided that no licence was required for WPEF VI Holding Coöperatief W.A., part of Waterland Private Equity Investments B.V., to acquire sole control of Nuts Groep B.V. Published in Staatscourant 2017 no. 19259, case 17.0270.22. This concerns an upper tier of the group and predates Jonaz B.V.’s entry into it.
Defects found in the stored corporate tree
The stored tree of 17 nodes places Jonaz B.V. correctly at depth 5 and its Dutch registration numbers resolve, but three problems are worth recording. First, it names node 95451358 Fiber Crew Holding B.V., while the ACM register records that KvK number as Fiber Crew B.V. and the parent’s own 2025 subsequent-events note also calls it Fiber Crew B.V.; the 2025 subsidiary list still uses the longer name, so at least one source is out of date. Second, the registration_number field mixes identifier systems without labelling them: the Belgian node "Elegant" carries BE0899305113, a Belgian enterprise/VAT number, not a company number of the same kind as the Dutch KvK numbers beside it. Third, the tree carries no ownership percentages at all, so nothing in it distinguishes the 100%-held energy companies from the roughly 50%-held fibre companies — a distinction the parent’s accounts make explicitly.
Data availability
Partial. The Dutch commercial register publishes neither group structures nor shareholdings for a B.V., and filed annual accounts are a paid product. Everything verified above comes from the listed parent-level publications and the ACM register; the direct legal owner of Jonaz B.V.’s shares, the ownership percentage at each individual step of the chain, and any subsidiary or branch of Jonaz B.V. itself could not be established. Whether Jonaz B.V. still exists as a separate legal entity today could not be established from any free source: it has no LEI, so GLEIF holds no retirement or successor record for it, and a Dutch domestic merger is announced in a newspaper under article 2:314 of the Civil Code rather than in the Staatscourant, so its absence from the official-publications repository proves nothing. The latest positive evidence is that the parent’s audited subsidiary list names Jonaz B.V. at 31 December 2025 in a report authorised on 28 May 2026, the ACM register still carries KvK 24403213 as Jonaz B.V. on 28 September 2026, and jonaz.nl is live and selling.

Frequently Asked Questions
What does Jonaz B.V. do?
Jonaz B.V. is a Dutch retail telecommunications provider registered with the Chamber of Commerce under KvK number 24403213 and based in Rotterdam. It sells fibre internet access, television and fixed telephony to households under the Jonaz brand, and is entered in the ACM register of telecoms providers as a provider of a public electronic communications service, registered on 23 September 2014. Its published proposition is a 1,000 Mbit/s symmetrical fibre connection at EUR 39.95 per month, with television at EUR 4.95 per month, in municipalities including Amersfoort, Almere, Hilversum, Lelystad, Nijkerk, Soest and Veenendaal. It is registered as a service provider, not as the operator of a public communications network.
Who owns Jonaz B.V.?
No shareholder records are held for Jonaz B.V.; the provider returned its standard no-data response for the Netherlands rather than a list, and the Dutch Handelsregister does not publish a general shareholder list for a B.V. The one ownership figure on the public record comes from the audited consolidated financial statements of Nuts Topholding B.V. (KvK 68242050, Amsterdam), which report a 50.05% share in the issued capital of Jonaz B.V. at both 31 December 2024 and 31 December 2025. That is the interest of the group as a whole; the direct legal shareholders of Jonaz B.V. are not named in any free source.
Who is Jonaz B.V.'s UBO (Ultimate Beneficial Owner)?
No ultimate beneficial owner of Jonaz B.V. could be identified. The Dutch UBO register has been closed to the general public since the Court of Justice of the European Union ruling of 22 November 2022, so it cannot be consulted. The ownership chain obtainable from the parent's published accounts stops at corporate entities and at an unnamed group described only as the founders of the underlying entities, so no effective percentage can be calculated and no natural person is named here. This is an absence of accessible information, not evidence that no beneficial owner exists.
What is Jonaz B.V.'s company registration number?
Jonaz B.V.'s registration number is 24403213, filed with Netherlands Chamber of Commerce (KvK) in Netherlands. Its current status on the register is active.
Is Jonaz B.V. still an active company?
Jonaz B.V.'s status on Netherlands Chamber of Commerce (KvK) is listed as active.
What is Jonaz B.V.'s registered address?
The registered address on file for Jonaz B.V. is Rotterdam, Netherlands.
What legal structure is Jonaz B.V. registered as?
Jonaz B.V. is registered as a Private limited company (Ltd.) in Netherlands.
What is Jonaz B.V.'s revenue?
No entity-level revenue figure for Jonaz B.V. could be verified. A Dutch B.V. files annual accounts with KvK, but they are a paid product and no free source publishes them. The audited consolidated statements of the parent, Nuts Topholding B.V., report only aggregate figures for the 2024 acquisitions as a whole (EUR 3,316 thousand of revenue and a loss before tax of EUR 2,061 thousand from the acquisition dates to 31 December 2024, across three acquired businesses) and do not break out Jonaz B.V. Those are group figures covering more than this company and must not be read as its revenue.
Is Jonaz B.V. listed on a stock exchange?
No. Jonaz B.V. is a private limited company (besloten vennootschap) and no securities of the company are admitted to trading on any exchange. Its parent group is privately held and likewise not listed; no stock-exchange listing or ticker exists for Jonaz B.V.
Who are the officers/directors of Jonaz B.V.?
One officer record is held for Jonaz B.V. and the provider reports it as complete: H.K. Tanis, role given as Director, status active, country NL, with no appointment date, no resignation date and no nationality. The record could not be independently verified, because the Dutch Handelsregister publishes directors and their powers of representation only in a chargeable extract. The total number of statutory directors in office and the age of the stored record could not be established, and no former officer is recorded.
Does Jonaz B.V. have a parent company or subsidiaries?
Jonaz B.V. is part of the Dutch energy and telecoms group headed by Nuts Topholding B.V. (KvK 68242050, Amsterdam). The parent's audited consolidated financial statements name Jonaz B.V., Rotterdam, at a 50.05% share in issued capital at 31 December 2024 and 31 December 2025, and describe it as one of three operational entities — with Ipronto Communications B.V. (KvK 24391901) and Spokkie B.V. (KvK 23092732) — under a fibre holding company, KvK 95451358, of which the group obtained 50.02% control on 8 November 2024 and the remaining 49.98% in April 2026. Jonaz B.V. has no subsidiaries or branches that could be established from any free source.
Can Zavia monitor changes to Jonaz B.V.'s ownership over time?
This profile reflects a point-in-time snapshot from Netherlands Chamber of Commerce (KvK). Zavia's monitoring API can track changes to Jonaz B.V.'s registered shareholders, officers, and group structure going forward, flagging updates as they're filed rather than requiring a manual recheck.
Can I access Jonaz B.V.'s data through an API?
Yes. Zavia's API connects directly to official government ownership registries across 195 countries and territories, including Netherlands, so records like Jonaz B.V.'s registration, shareholder, UBO, and group-structure data can be queried programmatically instead of viewed one page at a time.
Where does this company information come from, and how current is it?
This record is sourced directly from Netherlands Chamber of Commerce (KvK) and was last synced on 25 September 2026.
