12Build
12Build Sales B.V. is a Dutch private limited company — a besloten vennootschap met beperkte aansprakelijkheid (B.V.) — registered in the trade register of the Netherlands Chamber of Commerce (KVK) under number 63719444, at Ernst Machstraat 10, 7442 DL Nijverdal. The registry record carried on this profile gives the company’s status as Active and was last synchronised on 25 September 2026. Checked independently on 28 September 2026, the Dutch VAT number NL855370002B01 validated through the European Commission’s VIES service in the name 12BUILD SALES B.V. at that Nijverdal address, so the company was still registered under that name and at that address on that date. An active registry status is not in itself evidence that a company is trading.
The name shown at the top of this page, "12Build", is a trade name rather than the registered name. Three of the company’s own publications tie KVK 63719444 to the registered name 12Build Sales B.V.: the Dutch, English and Danish editions of its general terms of 1 February 2023, which each open by defining "12Build" as the besloten vennootschap met beperkte aansprakelijkheid 12Build Sales B.V., established at Ernst Machstraat 10 in Nijverdal and trading under Chamber of Commerce number 63719444; the privacy statement on 12build.com, which names 12Build Sales B.V. at the same address as the controller; and the German statutory imprint, which repeats the KVK number and adds establishment number 000032605609 and the VAT number above. Other companies also trade under the 12Build name, so the trade name alone does not identify this legal entity.
12Build Sales B.V. operates the 12Build platform at www.12build.com, a business-to-business tendering and procurement marketplace for the construction industry. Its general terms describe the platform as a restricted area of the website where an Offering Party — typically a main contractor — publishes a Work and invites quotations, and Requesting Parties, meaning subcontractors and suppliers, respond and exchange project documents and messages through it. The company also markets tender, bid and supplier management tools, subcontractor company profiles, an evaluation module, integrations with third-party construction software, and notifications of changes in a counterparty’s financial status. Access is contractually limited to businesses registered in a chamber-of-commerce trade register and operating in construction, and the German imprint states that the offering is directed exclusively at commercial users.
The same legal entity is named as the contracting party in the Dutch, Belgian, English, German and Danish editions of those terms, and the website is published in Dutch, Belgian Dutch, English, German, French and Danish, so it contracts with customers in several European markets. The only address on record for it, and the only office on its contact page, is Nijverdal.
Data quality notes on this profile
The legal form shown on the card as "Private limited company (Ltd.)" is a generic English label applied by the data feed. The company’s own Dutch terms give the form as a besloten vennootschap met beperkte aansprakelijkheid, which is not the same instrument as a UK "Ltd."; Dutch law has no form of that name.
The incorporation date shown as 1 January 2015 is the feed’s year-only placeholder rather than a filed date, and no incorporation or registration date should be read from this profile. KVK does record a date of registration and prints it in its Business Register Extract, but that extract is a paid product and the KVK public search does not answer automated requests. The company holds no Legal Entity Identifier, so GLEIF publishes no registry-validated creation date for it; a missing LEI is normal for a company of this size and is not evidence of anything.
No revenue, balance-sheet or employee figure for KVK 63719444 could be obtained. A Dutch B.V. deposits its annual accounts with KVK, and those filings are a chargeable product.

Shareholders
Shareholders of 12Build Sales B.V.
No shareholder of 12Build Sales B.V. (KVK 63719444) is disclosed on this profile, and none could be identified from a publicly accessible official source. The shareholder field stored for this company holds no rows at all. What it contains instead is the data provider’s "no data held" response, whose own text states that shareholder information for companies in the Netherlands is filed with the Chamber of Commerce and the UBO Register and that a nil result may mean the company is newly incorporated, a first filing deadline has not passed, filings are overdue, or UBO access is restricted. That records what the provider holds; it is not a statement about this company, and it is not evidence that 12Build Sales B.V. has no shareholders. A Dutch B.V. always has at least one.
The Netherlands does not operate a public share register for a besloten vennootschap. The shareholders’ register of a B.V. is kept by the company itself, and KVK’s own description of the details in its Business Register Extract covers the business name, address, business activities, date of registration and the names of the directors — not shareholdings. No ownership percentage is available for this company, and none has been inferred; no figure has been substituted for a missing one.
Nothing was found elsewhere. The Dutch repository of official publications at repository.overheid.nl, which is where merger and concentration notices concerning Dutch companies appear in the Staatscourant, returns no record for "12Build" or "12Build Sales". That nil result was tested against a control: the same query form returned 1,410 records for "Heineken" and 7,676 for "Nijverdal", so the search was working. GLEIF holds no LEI record for registration number 63719444, so there is no LEI-based direct or ultimate parent relationship to read.
Data availability
Shareholder information for this company is Restricted: it exists, but it is not published. Beneficial ownership is Not public — the Netherlands does operate a UBO register at KVK, but public access was withdrawn following the Court of Justice of the European Union’s judgment of 22 November 2022 in Joined Cases C-37/20 and C-601/20, and KVK states on its own product page that information from the UBO Register is not public and that an extract can be ordered only by someone authorised to sign for the organisation or otherwise entitled to view UBO data. Neither the absence of shareholder rows nor the closure of the UBO register is evidence that this company has no shareholders or no beneficial owner.

Officers
Directors and officers of 12Build Sales B.V.
No director or officer of 12Build Sales B.V. (KVK 63719444) is recorded on this profile. The officer field holds no rows: the data provider returned its "no data held" response, and the text of that response says officer data "is not available for this jurisdiction" and that the company may operate in a jurisdiction without mandatory officer filing.
That statement is wrong for the Netherlands and should not be read as a description of Dutch law. KVK’s own published description of the Business Register says it contains details of businesses and of their officials, that most of those details are open to the public, and that the publicly available details of an official or authorised representative include the name, title, authorisation and date of appointment. KVK’s product page for a Business Register Extract says the extract shows the names of the directors and who is authorised to sign on the company’s behalf. Dutch director information therefore exists and is public; it sits behind a paid KVK extract, which was not purchased for this profile, and the KVK public search does not answer automated requests. Nothing here is evidence that the company has no directors — a Dutch B.V. must have at least one.
One name is on the public record, from the company’s own statutory publication rather than from the register. The German-language imprint for 12build.com, published to satisfy § 5 of the German Telemediengesetz, names 12Build Sales B.V. of Nijverdal, KVK 63719444, as the operator of the site and states that it is represented by its managing director ("Vertreten durch die Geschäftsführer"): Patrick Aarbodem, CEO. This is the company’s own legally required declaration of who represents it, as published on 28 September 2026. It is not a register entry, it carries no appointment date, it does not say whether he is the only person so authorised, and it has not been checked against the Handelsregister. The same imprint names Edwin van Dijk, Head of Marketing, as the person responsible for content under § 18(2) of the German Medienstaatsvertrag; that is a media-law function, not a corporate office, and he is not identified as an officer of the company.
Nationality is Not disclosed for both individuals. Nationality does not appear in KVK’s list of publicly available details of an official, no source retrieved records it, and it must never be inferred from a name, an address or a place of business.
Data availability
Officer information for this company is Restricted: the Dutch trade register does record directors, their authorisation and their appointment dates, and most of that is public, but it is only obtainable through a chargeable KVK extract and the register’s public search rejects automated retrieval. No appointment date, termination date, country of residence or nationality is available for any person connected with KVK 63719444, and no officer list on this profile should be treated as complete or current.

Group Structure
Group structure of 12Build Sales B.V.
The corporate tree stored against this profile holds nine entities and places 12Build Sales B.V. (KVK 63719444) at the bottom of a seven-level chain. It carries no ownership percentages, no effective dates and no source reference, and no relationship in it could be verified from an official filing. What follows separates the one point that is independently on the record from the rest, which is not.
Independently on the record: the disclaimer published on the company’s own website states that "12Build is de merknaam van 12Build Secure B.V. te Nijverdal" — 12Build is the trade name of 12Build Secure B.V. of Nijverdal. That is the same name the stored tree shows two levels above this company, with KVK number 08157566. It establishes that a second Dutch company at Nijverdal holds the brand under which 12Build Sales B.V. trades, which is a real and sourced connection. It is not evidence of share ownership, and it does not establish a parent-subsidiary relationship. The intermediate entity in the stored tree, 12Build Group B.V. (KVK 61502596), is not named in any source retrieved.
Not on the record: above those entities the tree runs through Matchmaker BidCo B.V. (KVK 99264811) to three Australian companies named EstimateOne BidCo Pty Ltd, EstimateOne MidCo Pty Ltd and EstimateOne HoldCo Pty Ltd, and attaches EstimateOne Pty Ltd and Construction Link Limited (England and Wales, 09791821) as further members of the same group. The Australian identifiers stored beside those four names (676456401, 676455735, 676454685 and 130242554) are given without any statement of what kind of identifier they are, and none was resolved against an Australian register. Nothing retrieved supports any of this. Neither 12build.com nor estimateone.com mentions the other company anywhere, including in the statutory imprint, the privacy statement or the general terms, all of which name 12Build Sales B.V. alone. GLEIF holds no LEI for any of the entities, so no corroborated consolidation relationship exists to read. The Dutch official publications repository returns no record for "12Build", "12Build Sales", "Matchmaker BidCo" or "EstimateOne"; that nil result was validated against control searches, which returned 1,410 records for "Heineken" and 7,676 for "Nijverdal". At Companies House, Construction Link Limited (incorporated 23 September 2015, status Active, SIC 74909) records no relevant legal entity with significant control at all: its PSC entries are two individuals, each with ownership of more than 25% but not more than 50% of shares and voting rights, notified on 15 February 2025. Because an overseas company is generally not a "relevant legal entity" under the UK PSC regime, that neither confirms nor refutes an Australian parent — but no UK filing names an EstimateOne company as its owner.
Every relationship in the stored tree is therefore a possible relationship only, and none should be relied on. Provider-generated trees on this dataset have previously been found to chain custodial, nominee and unrelated entities into apparent ownership.
Verified corporate relationships
No corporate relationship involving 12Build Sales B.V. could be verified from an official filing or another authoritative source, so no relationship table is published here. The one sourced connection — that 12Build Secure B.V. of Nijverdal holds the 12Build trade name — is a brand statement made by the company itself, not an ownership disclosure.
Data availability
Corporate-linkage information for this company is Not public. The Netherlands publishes no share register for a besloten vennootschap, KVK’s Business Register Extract does not disclose shareholdings, and the UBO register has not been open to the public since the Court of Justice of the European Union’s judgment of 22 November 2022 in Joined Cases C-37/20 and C-601/20. Neither the immediate parent nor the ultimate parent of 12Build Sales B.V. could be confirmed, and the absence of confirmation is not evidence that the company is independent.

Frequently Asked Questions
What does 12Build do?
12Build Sales B.V. is a Dutch private limited company (besloten vennootschap met beperkte aansprakelijkheid, B.V.) registered with the Netherlands Chamber of Commerce under KVK number 63719444, at Ernst Machstraat 10, 7442 DL Nijverdal. It operates the 12Build platform at www.12build.com, a business-to-business tendering and procurement marketplace for the construction industry: under its own general terms of 1 February 2023, main contractors publish works and invite quotations, and subcontractors and suppliers respond and exchange project documents through the platform. Around that it markets tender, bid and supplier management tools, subcontractor profiles, an evaluation module, integrations with construction software and notifications of changes in a counterparty's financial status. Use is contractually limited to businesses registered in a chamber-of-commerce trade register and operating in construction. The name shown on this page, “12Build”, is a trade name; the registered name is 12Build Sales B.V., as its own general terms, privacy statement and German statutory imprint all confirm against KVK 63719444.
Who owns 12Build?
No shareholder of 12Build Sales B.V. is disclosed. The data provider holds no shareholder rows for this company at all — the stored field is its “no data held” response, which describes the provider's coverage rather than this company. The Netherlands does not operate a public share register for a besloten vennootschap: the shareholders' register is kept by the company itself, and KVK's Business Register Extract shows the business name, address, activities, date of registration and directors, not shareholdings. Searches of the Dutch official publications repository returned nothing for 12Build or 12Build Sales, validated against control searches that did return results, and GLEIF holds no LEI relationship record for KVK 63719444. The information is restricted, not absent: a Dutch B.V. always has at least one shareholder. No ownership percentage is available and none has been inferred.
Who is 12Build's UBO (Ultimate Beneficial Owner)?
No ultimate beneficial owner of 12Build Sales B.V. can be identified from a publicly accessible source, and none is asserted here. The Netherlands does maintain a UBO register at KVK, but it has not been open to the public since the Court of Justice of the European Union's judgment of 22 November 2022 in Joined Cases C-37/20 and C-601/20. KVK states on its own product page that information from the UBO Register is not public and that a UBO extract can be ordered only by a person authorised to sign for the organisation or otherwise entitled to view UBO data. No complete ownership chain for this entity is available from any source consulted, so no effective ownership percentage could be calculated. The absence of a published UBO is a restriction on access, not evidence that the company has none.
What is 12Build's company registration number?
12Build's registration number is 63719444, filed with Netherlands Chamber of Commerce (KvK) in Netherlands. Its current status on the register is active.
Is 12Build still an active company?
12Build's status on Netherlands Chamber of Commerce (KvK) is listed as active.
What is 12Build's registered address?
The registered address on file for 12Build is Nijverdal, Netherlands.
What legal structure is 12Build registered as?
12Build is registered as a Private limited company (Ltd.) in Netherlands.
What is 12Build's revenue?
No revenue, balance-sheet or employee figure for 12Build Sales B.V. could be verified. A Dutch B.V. deposits its annual accounts with the Netherlands Chamber of Commerce and those filings are a chargeable product, so entity-level figures for KVK 63719444 are not obtainable free of charge. No official source reviewed publishes a turnover or headcount for this company, and no figure circulating on company-directory sites has been used. Any figure published for the wider 12Build brand or for companies named in the stored corporate tree would be a different entity's figure and is not attributed here.
Is 12Build listed on a stock exchange?
12Build Sales B.V. is not listed on any stock exchange. It is a Dutch besloten vennootschap, a private company form whose shares are not freely transferable, and no securities regulator or exchange record naming KVK 63719444 was located. It has no ticker and holds no Legal Entity Identifier, so GLEIF publishes no record for it. Entities named elsewhere in the corporate tree stored on this profile are separate legal entities, and nothing about them should be read as a listing of this company.
Who are the officers/directors of 12Build?
No director or officer of 12Build Sales B.V. is recorded on this profile. The stored officer field holds no rows and carries the provider's message that officer data “is not available for this jurisdiction” — which is wrong for the Netherlands. KVK's own description of the Business Register says it records officials and that the name, title, authorisation and date of appointment of an official are publicly available, and its Business Register Extract shows the names of the directors and who is authorised to sign. The data exists and is public, but it sits behind a chargeable KVK extract that was not purchased, and the KVK public search rejects automated requests. One name is on the public record from the company's own statutory publication: the German imprint for 12build.com, published under § 5 of the Telemediengesetz, names 12Build Sales B.V., KVK 63719444, as the site operator and states that it is represented by its managing director, Patrick Aarbodem, CEO, as published on 28 September 2026. That is a company declaration, not a register entry; it carries no appointment date and does not say whether he is the only person so authorised. Nationality is Not disclosed.
Does 12Build have a parent company or subsidiaries?
No corporate relationship involving 12Build Sales B.V. could be verified from an official filing. The corporate tree stored on this profile holds nine entities and places the company at the bottom of a seven-level chain, with no ownership percentages, no dates and no source. One point is independently sourced: the company's own website disclaimer states that 12Build is the trade name of 12Build Secure B.V. of Nijverdal, the entity the tree shows two levels above it with KVK 08157566 — a brand statement, not an ownership disclosure. The rest is unsupported. The tree runs on through Matchmaker BidCo B.V. (KVK 99264811) to Australian companies named EstimateOne BidCo, MidCo and HoldCo Pty Ltd, and attaches EstimateOne Pty Ltd and Construction Link Limited (England and Wales, 09791821). Neither 12build.com nor estimateone.com mentions the other company anywhere; GLEIF holds no LEI for any of them; the Dutch official publications repository returns nothing for 12Build, Matchmaker BidCo or EstimateOne, validated against control searches; and Companies House records no corporate person with significant control for Construction Link Limited, only two individuals. Treat every relationship in the stored tree as a possible relationship only.
Can Zavia monitor changes to 12Build'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'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'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'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.
