12Build Secure B.V.
About 12Build Secure B.V.
12Build Secure B.V. is a Dutch private limited company — a besloten vennootschap met beperkte aansprakelijkheid (B.V.) — registered in the Netherlands Handelsregister under KvK number 08157566, with its registered address at Ernst Machstraat 10, 7442 DL Nijverdal, Overijssel. Its VAT registration NL8177.46.596.B01 validated as active in the European Commission’s VIES system on 28 September 2026, returning the registered name 12BUILD SECURE B.V. at that same Nijverdal address. The registration was shown as active in the provider record at its last synchronisation on 25 September 2026.
12Build Secure B.V. holds the 12Build brand. The disclaimer published on 12build.com states, in both its Dutch and its English edition, that 12Build is the trade mark of 12Build Secure B.V. of Nijverdal. 12Build is a business-to-business tendering platform for the construction industry: main contractors create projects, break them into work packages and send out requests for quotation; subcontractors and suppliers receive those requests, submit priced bids and maintain profiles in a searchable marketplace of construction specialists. The site publishes tender-management, bid-management and supplier-management modules, integrations with Dalux, Catenda, IBIS, KPD and SharePoint, and Dutch, Belgian, German and English-language editions.
Which legal entity carries that trading activity has changed over time, and it matters for anyone matching this record. All three language editions of the 12Build general terms dated 1 February 2023, the privacy statement and the German §5 TMG imprint name a different registered company — 12Build Sales B.V., KvK 63719444, at the same Nijverdal address — as the contracting party and data controller for the platform. Archived copies of 12build.com show the earlier position: on 21 May 2013 and on 8 January 2014 the site’s own contact block published KvK 08157566 together with VAT NL8177.46.596.B01, from Nijverdalseweg 143 in Rijssen with a sales office in Zwolle, under the name Aanenuitbesteden.nl B.V. in the 2013 capture and under the 12Build name in the 2014 one. By the capture of 2 April 2016 the contact page carried KvK 63719444 instead. No free public source establishes turnover, employee numbers or current trading activity for 12Build Secure B.V. itself, and none of the platform’s published scale can be attributed to this entity.
Two fields on the information card above are not reliable. The incorporation date shown as 1 January 2026 is a year-only placeholder rather than a filed date, and it is contradicted by the record itself: KvK 08157566 is an old-format registration number from the pre-2014 regional chamber for Oost Nederland at Enschede — which the company’s disclaimer still names as the office where its general terms were deposited — and the company’s own website was already publishing that number in May 2013. The real incorporation date could not be established from a free source. The legal form shown as "Private limited company (Ltd.)" is a generic label; this entity is a Dutch B.V., a distinct legal form from a UK limited company.

Officers
Directors and officers of 12Build Secure B.V.
No director or officer of 12Build Secure B.V. (KvK 08157566) could be established from a free authoritative source, and none is named here. That is a limit on what could be retrieved, not a finding about the company.
The provider record for this company holds an officer stub instead of officer rows. Its text asserts that officer data "is not available for this jurisdiction" and that the company "may operate in a jurisdiction without mandatory officer filing". That is wrong for the Netherlands. A Dutch B.V. registers its bestuurders in the Handelsregister, and KVK’s own product page for the Uittreksel Handelsregister describes the extract as showing the business name, address, activities, registration date and the names of the directors or owners, and says it is what you use to check who the directors are and who may sign on behalf of the company. Directors of 12Build Secure B.V. therefore exist on the Dutch register; they were simply not retrieved.
A named individual who is not an officer of this company
The German §5 TMG imprint published on 12build.com names one person as CEO and statutory representative (Geschäftsführer). That imprint is filed for 12Build Sales B.V., KvK 63719444 — a different registered company sharing the Ernst Machstraat 10 address in Nijverdal. It is not evidence of any appointment at 12Build Secure B.V., and this profile does not carry it across. The same applies to the two individuals recorded on the UK persons-with-significant-control register of CONSTRUCTION LINK LIMITED, an entity that appears in this company’s stored corporate tree: they hold no established position in 12Build Secure B.V.
Data availability
Officer information for 12Build Secure B.V. is Restricted, not absent. KVK’s free company search is a client-side application that returns no register content to an automated request, and the Uittreksel Handelsregister that carries the director names is a paid product; the dated history of appointments and resignations sits in a separate paid product, Handelsregister Historie. Nationality is recorded here as Not disclosed — no source consulted publishes a nationality for any person connected with this company, and nationality is never inferred from a name, an address or a country of residence. No appointment date, resignation date or way of representation is published here for the same reason.

Group Structure
Group structure of 12Build Secure B.V.
No parent, subsidiary or sister-company relationship involving 12Build Secure B.V. (KvK 08157566) could be verified from an official filing or another authoritative source. Nothing is presented here as a verified relationship.
The provider record does store a corporate tree: nine nodes, maximum depth seven, with this company flagged as the selected node at depth five and carrying the correct identifier NL 08157566. The stored chain runs ESTIMATEONE HOLDCO PTY LTD → ESTIMATEONE MIDCO PTY LTD → ESTIMATEONE BIDCO PTY LTD → Matchmaker BidCo B.V. → 12Build Secure B.V. → 12Build Group B.V. → 12Build Sales B.V., with ESTIMATEONE PTY LTD and CONSTRUCTION LINK LIMITED attached alongside the Dutch branch. No ownership or voting percentage is stored for any edge, so no effective percentage can be reported or calculated, and none is substituted with zero.
Two features of that tree warrant caution. It places an entity named 12Build Group B.V. below 12Build Secure B.V., which is the opposite of the arrangement those names imply. And for CONSTRUCTION LINK LIMITED the UK register does not corroborate a corporate parent: its persons-with-significant-control register records two active individual PSCs, each holding more than 25% and not more than 50% of both shares and voting rights, notified on 15 February 2025, with no relevant legal entity registered. Because an Australian company is not a relevant legal entity under the UK PSC regime, control exercised through one would be traced to individuals — so this is not a contradiction of the stored tree, but neither is it evidence for it.

Each row records only whether the entity exists as named in an official register. It does not verify any relationship between the entities.

A shared address and a shared website are not evidence of a corporate relationship. 12Build Secure B.V. and 12Build Sales B.V. are two separate registered companies at Ernst Machstraat 10 in Nijverdal operating behind one brand and one website, and that is the extent of what the sources establish about them.
Data availability
Corporate-linkage information here is Not public. The provider’s own shareholder stub for this company points to KVK and the UBO register rather than naming holders; KVK’s free company search returns no register content to an automated request; and the Dutch UBO register has not been open to the public since the Court of Justice of the European Union’s judgment of 22 November 2022 — KVK’s page for the UBO extract states that UBO data is not public and that an extract can be ordered only by a person with rights to view it.
Every nil result above was checked with a positive control through the same query form before being reported. TED (api.ted.europa.eu/v3/notices/search, query FT ~ "08157566") returned no procurement notice naming this company, while the identical query form returned notices for KvK 34366966. The Dutch official-publications service repository.overheid.nl/sru returned no record for "12Build", "12Build Secure" or "08157566", while the same query form returned 7,676 records for "Nijverdal". GLEIF holds no Legal Entity Identifier for any 12Build or EstimateOne entity, on a query form that returns two records for Heineken N.V. These are absences of evidence; none of them is evidence that the company is independent, has no parent or has no subsidiaries.

Frequently Asked Questions
What does 12Build Secure B.V. do?
12Build Secure B.V. is the Dutch besloten vennootschap (B.V.) that holds the 12Build brand. The disclaimer published on 12build.com states, in its Dutch and English editions, that 12Build is the trade mark of 12Build Secure B.V. of Nijverdal. 12Build itself is a business-to-business tendering and bid-management platform for the construction industry, covering tender management, bid management and supplier management. Note that the platform's customer contracts, its privacy statement and its German § 5 TMG imprint are all in the name of a different registered company, 12Build Sales B.V. (KvK 63719444), so the platform's published activity and scale cannot be attributed to 12Build Secure B.V. No free public source describes what this entity trades in today beyond holding the brand.
Who owns 12Build Secure B.V.?
Not disclosed. The provider holds no shareholder rows for 12Build Secure B.V. — the stored field is a stub whose own text points to KVK and the UBO register rather than naming any holder. KVK's free company search is a client-side application that returns no register content to an automated request, so no shareholder of this company could be verified from a free source, and no ownership percentage is published here. This is a restriction on access; it is not evidence that the company has no shareholders.
Who is 12Build Secure B.V.'s UBO (Ultimate Beneficial Owner)?
Not disclosed, and not obtainable from a public source. The Dutch UBO register has not been open to the public since the Court of Justice of the European Union's judgment of 22 November 2022, and KVK states that UBO data is not public and that a UBO extract can be ordered only by a person with rights to view it. No ultimate beneficial owner of 12Build Secure B.V. is published here. None should be inferred from the provider's stored corporate tree either: that tree carries no ownership percentage on any edge, and none of its relationships could be corroborated by an official filing.
What is 12Build Secure B.V.'s company registration number?
12Build Secure B.V.'s registration number is 08157566, filed with Netherlands Chamber of Commerce (KvK) in Netherlands. Its current status on the register is active.
Is 12Build Secure B.V. still an active company?
12Build Secure B.V.'s status on Netherlands Chamber of Commerce (KvK) is listed as active.
What is 12Build Secure B.V.'s registered address?
The registered address on file for 12Build Secure B.V. is Nijverdal, Netherlands.
What legal structure is 12Build Secure B.V. registered as?
12Build Secure B.V. is registered as a Private limited company (Ltd.) in Netherlands.
What is 12Build Secure B.V.'s revenue?
No revenue figure for 12Build Secure B.V. could be obtained. A Dutch B.V. must file annual accounts with KVK and those filings are public, but KVK supplies them only as a paid product and there is no free machine-readable route to them, so entity-level figures are behind paid access rather than unpublished. Any turnover or scale figure quoted for the 12Build platform relates to the business as a whole and not to this legal entity; the platform's customer contracts are in the name of 12Build Sales B.V. (KvK 63719444).
Is 12Build Secure B.V. listed on a stock exchange?
No. 12Build Secure B.V. is a privately held Dutch B.V. with no stock-exchange listing and no ticker symbol. It also holds no Legal Entity Identifier: a GLEIF search returned no LEI record for it, on a query form that returns two records for Heineken N.V.
Who are the officers/directors of 12Build Secure B.V.?
Not disclosed here, because none could be retrieved from a free authoritative source. The provider record stores an officer stub asserting that officer data "is not available for this jurisdiction" — which is wrong for the Netherlands. A Dutch B.V. registers its bestuurders in the Handelsregister, and KVK describes its Uittreksel Handelsregister as showing the names of the directors or owners and who may sign on behalf of the company. The directors exist on the register; they were not retrieved because KVK's free search is not machine-readable and the extract is a paid product. The German § 5 TMG imprint on 12build.com names a CEO, but that imprint is filed for 12Build Sales B.V. (KvK 63719444), a different company at the same address, and evidences no appointment at 12Build Secure B.V. Nationality is Not disclosed.
Does 12Build Secure B.V. have a parent company or subsidiaries?
No group relationship involving 12Build Secure B.V. is verified. The provider stores a nine-node tree placing this company at depth five, beneath Matchmaker BidCo B.V. (NL 99264811) and an EstimateOne HoldCo / MidCo / BidCo chain in Australia, and above 12Build Group B.V. (NL 61502596) and 12Build Sales B.V. (NL 63719444). No ownership percentage is stored for any edge, and no official filing corroborating any of those relationships was found. Several of the individual entities do check out — ESTIMATEONE HOLDCO PTY LTD (ABN 74 676 454 685) and EstimateOne Pty Ltd (ABN 24 130 242 554) are on the Australian Business Register, and CONSTRUCTION LINK LIMITED (09791821) is active at Companies House — but an entity existing is not the same as an ownership link. Treat the tree with care: it places an entity named 12Build Group B.V. below this company, the opposite of what the names imply.
Can Zavia monitor changes to 12Build Secure 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 12Build Secure 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 12Build Secure 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 12Build Secure 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.
