Dennis Nowak, a German national with a history of involvement in cryptocurrency and multi-level marketing schemes, has emerged as a key figure in Voidara, an AI agent-based platform launched in early 2025. The company's website, voidara.ai, privately registered on April 14, 2025, provides no public information about its ownership or executives.
Nowak, who claims Swiss residency on his LinkedIn profile, hosts official Voidara marketing webinars, which are featured on the company's YouTube channel. His appearance with Voidara follows the January 2025 collapse of Flyback Solutions, another one of his ventures, which operated as an MLM crypto scheme.
Nowak first drew attention in mid-2019 during a Swiss investigation into MyCryptoWorld, Infinity Economics, and We Go Crypto. MyCryptoWorld was identified as an MLM "shitcoin" pump and dump scheme. Infinity Economics and We Go Crypto were non-MLM cryptocurrency fraud operations. The results of that Swiss investigation remain unconfirmed.
Following his crypto activities, Nowak returned to LavyLites, a Hungarian multi-level marketing company. BusinessForHome reported his monthly income from LavyLites at $80,000 around mid-2016. But his earnings significantly declined by late 2020. In October 2020, Nowak publicly demanded one million euros in alleged unpaid commissions from Lavylites and threatened legal action, though no public resolution followed.
Nowak then launched Elixoo in early 2021. This scheme, which has since collapsed, functioned as a pay-to-play MLM centered on obscure meteorite powder supplements. In late 2023, he initiated Flyback Solutions, an MLM crypto Ponzi scheme involving "shitcoin" pump and dump tactics. Flyback Solutions ceased operations in January 2025, preceding Voidara's launch by only a few months.
Voidara also features Renz Eduard Deelstra, also known as Renze Deelstra, as a "top leader & trainer." Deelstra, from the Netherlands, has his own history with fraudulent schemes. He was identified as a net-winner in the notorious Zeek Rewards Ponzi scheme, which collapsed in 2012 and defrauded over a million people of hundreds of millions of dollars.
After Zeek Rewards, Deelstra continued to recruit for the Crowd1 Ponzi scheme. Crowd1, which claimed to sell educational packages and generate revenue from gaming and gambling, was widely flagged by regulators globally as an illegal pyramid scheme. Deelstra was terminated from Crowd1 in 2021. He then launched NewChoyce, another MLM crypto Ponzi, which collapsed within months and was subsequently rebranded as GreenChoyce.
By 2022, GreenChoyce was rebooted again as "Eco and GreenChoyce." This iteration also collapsed. Its former website now redirects to "GreenChoyce International," which appears to be another unsuccessful attempt to revive the brand. Deelstra's consistent pattern involves moving from one collapsed scheme to the next, often with rebranded versions.
Voidara adheres to one legal standard by including an "imprint" page on its website, a requirement for businesses operating in Germany and several other German-speaking countries. This page reveals the company operates through ChainPay Solutions EOOD, a shell entity purportedly registered in Bulgaria. And such arrangements commonly obscure true ownership and complicate regulatory oversight.
The history of both Nowak and Deelstra suggests a pattern of promoting multi-level marketing schemes that involve cryptocurrency or questionable products, often ending in collapse and investor losses.
