Jonathan Grothaus is CEO (the person leading the company) and co-founder (someone who started the company with others) of myflexbox, a provider of open parcel stations headquartered in Salzburg. In 2018, the idea for a carrier-independent smart-locker network won Salzburg AG's internal challenge. In 2019, it became Salzburg AG's first corporate startup. myflexbox was spun off as an independent, wholly owned Salzburg AG subsidiary on 1 July 2022.
The sources document the challenge win for the idea. They do not attribute a personal win to Jonathan Grothaus and Peter Klima.
For teenagers and parents in Salzburg, the profile shows a path from a company idea to a spin-off. The next step is to check Grothaus's role and the current network size in myflexbox's announcement of 1 July 2026. Then assign older finance and growth figures to their historical dates.
Where the work becomes concrete in Salzburg
Company, address, and registration
The myflexbox legal notice names MYFLEXBOX Austria GmbH at Warwitzstraße 8, 2nd floor, 5023 Salzburg. Jonathan Grothaus is listed there as management, Peter Klima as authorized signatory. The company is registered under FN 568589 k at the Provincial Court of Salzburg.
Founding and team
According to WKO Salzburg, Jonathan Grothaus, Lukas Wieser, and Peter Klima founded myflexbox in 2018. Grothaus and Klima had been Salzburg AG employees. Wieser joined later as a third co-founder.
An official myflexbox announcement on the expansion to Germany separates the company stages. In 2018, the smart-locker idea won Salzburg AG's internal challenge. In 2019, it became Salzburg AG's first corporate startup. The spin-off as an independent company followed on 1 July 2022. myflexbox was then a wholly owned Salzburg AG subsidiary.
Growth in numbers
The WKO article reflects the position in March 2024. It reports roughly 500 parcel stations in Austria around the turn of 2023/24. It reports roughly 150 stations in Germany. The expansion numbers in the article were future targets from that historical point.
Also as of March 2024, WKO describes staff growth from 25 people in early 2023 to nearly 70. Revenue in 2023 was in the single-digit millions according to the article. At that time, myflexbox worked with carriers including DPD, FedEx, UPS, and GLS.
A current myflexbox company announcement dated 1 July 2026 lists Jonathan Grothaus as CEO and founder. It reports more than 2,300 parcel lockers across over 800 cities and municipalities in Germany and Austria. Both numbers are first-party company claims.
In February 2023, the STAR IV fund of STAR Capital invested 75 million euros according to myflexbox's funding announcement. WKO says STAR Capital then held 50.6 percent of the shares and Salzburg AG held 49.4 percent. In March 2024, WKO described it as the largest investment in a Salzburg startup up to that point.
Why the Salzburg connection holds up here
Five sources support different parts of this profile. The legal notice documents the company, address, and registration. The myflexbox expansion announcement documents the challenge, the 2019 corporate startup, and the 2022 spin-off. WKO Salzburg documents the founding, team, and figures as of March 2024. The funding announcement documents the investor, amount, and date. The company announcement of 1 July 2026 provides the current role and two current network figures as first-party claims.
Why this can matter to teens
For teenagers, this path shows a rarely described founding model. The idea won an internal competition in 2018. It became a corporate startup in 2019. The independent spin-off followed only in 2022. Outside investors came later.
The subject itself is also unusual for a youth profile: parcel stations, last-mile delivery, and CO2 savings in deliveries are real infrastructure problems that cities like Salzburg are working on, far removed from gaming or social media.
What you can specifically take away from this
As you read, compare which fact comes from which source. The chronology comes from myflexbox's 2022 announcement. WKO Salzburg supports the founding, team, and historical growth figures. The 2026 company announcement supports the current role and network size.

What matters so this profile stays honest
As of 31 July 2026, the statements here rely on the legal notice, WKO Salzburg, and three myflexbox announcements. The 2022 announcement supports the company chronology. The WKO figures belong to March 2024. The network size of more than 2,300 lockers in over 800 cities and municipalities comes from a company announcement dated 1 July 2026. It is marked as a first-party claim.
The sources name no open internships or visiting rules for teenagers. SalzburgTeen therefore runs this profile as career and founding-path orientation, not as a participation offer.
Conclusion
Jonathan Grothaus's path has three clearly documented company stages. In 2018, the smart-locker idea won the internal challenge. In 2019, it became Salzburg AG's first corporate startup. The independent spin-off as a wholly owned subsidiary followed on 1 July 2022. Historical WKO figures and current company claims remain separate from that chronology.
