KEY POINTS • Connections & Associations
Despite operating in diverse and disparate industries, many of the companies documented in this report share overlapping directorship and ownership structures and have been connected with the jewellery industry. • Hello & Goodbye
Representatives of many of these companies, which have recently faced insolvency proceedings, have appeared as guest speakers at Jewellery Industry Network events. • Lost Count?
Andy Phanthapangna supposedly represented Apeirogon Technologies at the Jewellery Industry Summit four years before the company was registered with corporate regulators. |
As reported, Angkham (Andy) Phanthapangna's name appears across numerous companies that were placed into liquidation by the same South Australian insolvency firm, Bernardi Martin.
As previously detailed here, four Phanthapangna-owned companies, including Grow Fit Fund, Banquet Creative, Achievement Collective, and AG Marketing Group, collapsed between January 2024 and October 2025.
Remarkably, there are many more companies worthy of examination.
Despite operating in diverse and disparate industries, including advertising, disability services, labour hire, IT, and charitable fundraising, these companies share overlapping directorship and ownership structures.
Indeed, at least eight companies linked by shared business addresses and creditor relationships have been involved in insolvency proceedings. At the same time, Australian Securities and Investments Commission (ASIC) records show action was taken to wind-up a ninth company.
And most interestingly of all, many of these collapsed companies have been ‘connected’ to the jewellery industry.
Indeed, many of these companies have been exhibitors at jewellery trade shows and summits organised and/or owned by the Jewellery Industry Network, founded by Phanthapangna and Laura Moore, former vice president of the Jewellers Association of Australia (JAA).
In some cases, representatives of these collapsed companies have appeared at these events as guest speakers.
Additionally, Jewellery World also has many connections to this complex network of companies. This is particularly true given that the company that, at one stage, owned the trade publication, was issued a wind-up notice in December 2023 by the Australian Taxation Office (ATO). It was subsequently dismissed in February 2024.
Jeweller does not suggest that any of the individuals referenced in this story have acted unlawfully.
Unravelling the connections
ASIC records list many Australian companies that trade under the name ‘Apeirogon’. For the curious, 'apeirogon' is a mathematical term used to describe a polygon with a countably infinite number of sides.
As far as Jeweller can establish, there are at least four ‘Apeirogons’ for which Phanthapangna can be identified as being a director, shareholder, or somehow associated with. Among them is Apeirogon [ACN: 611 647 486], the oldest entity, registered in April 2016 at 43 Port Road, Thebarton in Adelaide.
This business address will appear repeatedly in a long list of companies, including some associated with the jewellery industry.
» Company: Apeirogon
» ACN: 611 647 486
» Status: Liquidated
According to ASIC records, Phanthapangna is listed as a director and shareholder of this company, which appointed the insolvency firm Bernardi Martin on 15 August 2025.
It was subsequently liquidated on 25 August 2025 with unsecured liabilities totalling $2,397,874, including $991,087 owed to the Australian Taxation Office. At some point, the name was changed from Aperirogon Pty Ltd to ACN: 611 647 486.
Martin's liquidation report notes: "I am informed that the Company operated a business app development business, which ceased trading in July 2025. The business was sold to what I am informed is a non-related company for $70,000, of which $15,000 is still outstanding."
Acting as a company representative, Phanthapangna spoke at the Jewellery Industry Summit in July, 2021.
The inaugural event was promoted in Jewellery World and had the backing of the Jewellers Association of Australia.
With that said, some of the finer details are worth clarifying.
At the time, Jo Tory was president of the JAA and wrote: “The JAA along with event organiser, Moore Events, we are hosting a cocktail party to celebrate this worthy milestone. You simply need to register your attendance at the Jewellery Industry Summit.”
Moore Events is a private events management company registered by Moore on 19 September 2019. Conversely, the Jewellery Industry Network was registered in September 2020.
Phanthapangna 'headlined' a speakers list at his own event and his seminar topic was promoted as ‘Technology in the Jewellery Industry’. He was promoted in a Jewellery World article as the ‘CEO Aperigon Technologies’ (sic).
Along with the company’s name being misspelled, it’s more important to note that the company - Apeirogon Technologies – didn’t actually exist at the time of the event, according to ASIC records. That will be explained in detail below.
Again, acting for Apeirogon, Phanthapangna also spoke at the Jewellery Industry Fair in February 2022, thereby promoting his own company at an event organised by the Jewellery Industry Network, a company he and Moore also owned.
Apeirogon by name, apeirogon by nature
There are at least three more companies sharing the name ‘Apeirogon’, in addition to the one now liquidated.
Two of these companies shared the same registered address as Jewellery World and the soon-to-be liquidated children’s charity, Grow Fit Fund. Research shows that 99.9 per cent of charity’s donations was spent administration costs, which included 89.9 per cent of the donations being paid to staff (see Table to right).
As previously detailed, Phanthapangna was the charity’s director, and Moore promoted herself as a member of the Grow Fit Fund board.
Another ‘Apeirogon’ was formed in September 2023 - Apeirogon Corporation [ACN: 671 737 394] - with a registered address of 43 Port Road, Thebarton. Phanthapangna was a director and shareholder via Alphabet Technologies; however, there were recent changes at that company.
Current ASIC records indicate that Phanthapangna is no longer a director of Apeirogon Corporation, and Alphabet Technologies is no longer a 60 per cent shareholder.
Instead, a new company has replaced Phanthapangna’s entity – that being Apgon Australia [ACN 683 901 288].
This new company was registered with ASIC in January this year and is owned by Brandon Sithanh Phanthapangna.
The website for Apeirogon Corporation states: “served by Banquet Creative”, the other Phanthapangna-owned company in liquidation.
Yet another business using the name is Apeirogon Group [ACN: 667 727 488], which was registered in May 2023 and is also registered to 43 Port Road, Thebarton.
Phanthapangna was a director of this company and a 100 per cent shareholder via his Alphabet Technologies until March 2025. ASIC now records Apgon, owned by Brandon Phanthapangna, as a 50 per cent shareholder in this company.
There is also another business registered as Apeirogon, and this one is held by Sandra Jane Phanthapangna. The same ASIC record shows another business, Acumend.
It is interesting to note that the Liquidator's report for two of the Andy Phanthapangna-owned collapsed companies records Acumend Australia as being owed $37,000.
WHOIS, the public directory for domain name registrations, shows acumend.com.au as being registered by Sandra Jane Phanthapangna.
Remarkably, the list of ‘Apeirogons’ does not stop there!
Only two months ago, another appeared on the ASIC database - Apeirogon Technologies [ACN: 689 783 195] was registered on 6 August 2025. This was 10 days before Bernardi Martin was appointed to the now-liquidated Apeirogon Pty Ltd.
Although only registered this year, Apeirogon Technologies was the company Phanthapangna supposedly represented at the Jewellery Industry Summit four years earlier, as promoted by Jewellery World.
It’s interesting to note that neither Phanthapangna nor Alphabet Technologies appear on this new company’s ASIC record. The director, secretary, and shareholder are recorded as Jett Ferro, and it is noted that the shares are ‘beneficially held’.
With that said, the registered address is the same as almost all other Phanthapangna-associated ASIC records: Rose Street, Mile End in Adelaide.
A LinkedIn account for Jett Ferro lists him as 'Head Of Web3 Product Development’ at Apeirogon. Ferro also appeared alongside Phanthapangna in social media posts promoting the 2022 Jewellery Industry Fair.
Until recently, there appeared to be a website [apeirogontech.my] connected to the newly-formed Apeirogon Technologies which stated it was “served by Banquet Creative”, the marketing company owned by Phanthapangna. However, that site is now inactive.
» Company: Diverso Resources
» ACN: 666 528 856
» Status: Liquidated
Diverso Resources is another company associated with Phanthapangna that has been liquidated. It was registered with ASIC on 16 March 2023, and the director and secretary were recorded as Ivan Vantagiato.
The company’s shareholders are listed as Alphabet Technologies, owned by Phanthapangna, along with two other companies, S&I Vantagiato and Vantagiato. Bernardi Martin was appointed as liquidator on 17 February 2025.
It collapsed with $1,835,682 in unsecured creditors and worse; Martin’s report did not mince words: “I am of the opinion that the Company has been insolvent since its inception…”.
The Diverso Resources website remains live despite the company being placed into liquidation and it's interesting because it demonstrates further connections with the jewellery industry and the intricate web of associated companies.
“We are committed to providing the highest level of service by building long lasting relationships with both our candidates and clients. As part of the Apeirogon Group we have access to internal resources and a network which sets us apart from the rest,” the website explains. [Emphasis added]
Under a webpage titled ‘Partnerships and Connections’, it lists Banquet Creative and Apeirogon, two Phanthapangna-owned businesses which, as mentioned, have since been liquidated.
More interestingly, this webpage also describes a partnership with Industry Group Network, a company formed by Phanthapangna and Moore in September 2020. This is the company that acquired Jewellery World in July 2022 and which the Australian Taxation Office issued a wind-up notice in January 2024.
Diverso Resources is described as “a family owned and operated agency specialising in recruitment, shutdowns and labour hire” and goes on to explain, "At Diverso, we deeply value diversity, which is why we have intentionally established a Board of Advisors that embodies this principle.”
The website lists the ‘Board of Advisors’ as Ilaria Vantagiato (director), Bisahr Phanthapangna, Clinton Wilson, and Jye Sims. Sims, as previously noted, was a co-founder of Achievement Collective, another company owned by Phanthapangna that was promoted to the jewellery industry.
In another interesting example of an association between these companies, the social media account of the company's director and secretary, Ivan Vantagiato, details a sponsorship agreement between a motorsports company, SlipStream Autosport, and the children’s charity, Grow Fit Fund.
Regarding related party transactions, the liquidator’s report noted that Diverso Resources is owed around $150,000 by Apeirogon, Fullhammer, Banquet Creative and National Apparel Solution Unit Trust.
While Diverso Resources was liquidated 10 months ago, it should not be confused with Diversa Resources [ACN: 666 297 810] – yet another company associated with Phanthapangna.
Diversa Resources was registered with ASIC on 7 March 2023, around a week before Diverso Resources. Phanthapangna is the director and secretary of Diversa Resources, and his company, Alphabet Technologies, is listed as the shareholder.
To avoid confusion, Diverso Resources (with an ‘o’) was liquidated by Bernardi Martin and its website remains live, while Diversa Resources (with an ‘a’) remains operational; however, it does not appear to have a website
» Company: QED Technology
» ACN: 644 064 611
» Status: Liquidated
QED Technology was registered with ASIC on 4 September 2020. Phanthapangna was recorded as director and secretary, and Alphabet Technologies was the shareholder. At the time of publication, the company’s website is still active and displays an address of 5 Hackney Road, Hackney in Adelaide.
QED Technology collapsed with $2,168,761 in unsecured creditors. One of the creditors was the Jewellery Industry Network.
Again, Hugh Martin of insolvency firm Bernardi Martin was appointed to the company on 20 December 2024, and QED Technology was liquidated three days after Phanthapangna quit the Jewellery Industry Network.
Martin’s report details seven loan accounts totalling more than $230,000 in director-related transactions with: Andy Phanthapangna, Diverso Resources, Achievement Collective, Apeirogon, Bnqmedia, Grow Fit Fund and Jewellery Industry Network.
Interestingly, it also appears on the administrator’s report for Grow Fit Fund - QED Technology owes Grow Fit Fund $9,119.
In addition, QED Technology’s address is listed as 5 Hackney Road, Hackney, the same address as Banquet Creative, which in turn appears on the Grow Fit Fund creditors listing with a claim of $34,337 owed.
It should be noted that the Acumend website registered by Sandra Jane Phanthapangna also shows the same address - 5 Hackney Road, Hackney.
In a similar way to Diverso/Diversa, QED Technology should not be confused with QED Media, which is owned by The Trustee for The Apeirogon Trust, which in turn is connected to the now-liquidated Apeirogon [ACN: 611 647 486].
WHOIS shows that the QED Media website was registered by Andy Phanthapangna of Apeirogon Pty Ltd.
Even more to come…
Outlined in these articles is a network of companies, many of which have been liquidated, and which have connections to the jewellery trade and, in particular, the Jewellery Industry Network.
It reveals consistent patterns of shared directorships, recurring corporate addresses, and overlapping ownership. However, research has discovered that the complexity does not stop here.
The focus of the next report will be on another group of companies including, but not limited to, Industry Group Network.
As stated above, Industry Group Network acquired Jewellery World in 2022 and WHOIS provides another insight into this complex corporate structure.
This website was registered by Apeirogon Pty Ltd, the company that was liquidated by Bernardi Martin on 25 August.
The domain registrant contact person is listed as Laura Moore.
Editor's Note: This publication’s interest in director-related and family-related businesses associated with the Jewellery Industry Network was spurned during the research for the ‘Jewellery Trade Shows’ project, which was published between June 2024 and March 2025.
The purpose of that project was to provide readers with a like-for-like comparison of two jewellery industry trade shows held in Sydney on the same weekend in August 2024.
During that project’s research, the volume of director and ownership overlap between companies associated with the Jewellery Industry Network, Jewellery Industry Fair, and Jewellery World was noted, and this report is a result of that investigation.
This exhaustive research is based on publicly available information, and, as mentioned, numerous attempts were made to contact relevant individuals for comment.
Jeweller does not suggest that any of the individuals referenced in this story have acted unlawfully.
Readers must assess for themselves the significance of director-related and family-related connections between businesses and the wider jewellery industry.
