The InterGest partner meeting in Istanbul focused on intercultural exchange - a valuable opportunity for Natalie to strengthen international networks and bring new perspectives to her daily work.

The future was also shaped in Cologne: Liss Heller visited Maik Pfingsten to work on new concepts relating to tax-optimized wealth accumulation. Product development, clear implementation strategies and creative energy made this workshop a significant step towards innovative advisory solutions. The results can be found here.

Another highlight: our blog celebrated its 10th anniversary. For a decade, we have been providing content that informs, inspires and makes you think - for entrepreneurs who want more than just numbers.

Inspiration knows no boundaries.

2023 was a year full of inspiring encounters and exciting impulses - both at home and abroad. We were on business trips to South Africa, Sweden, Hamburg, Milan and Mallorca - always with the aim of gaining new perspectives, strengthening networks and bringing a breath of fresh air into our work.

A special moment: Heller Consult celebrated its 32nd birthday - without a big party, but with all the more gratitude and a touch of confetti on the red carpet.

In the summer, things became sustainable: with our second-hand BAZAAR in Porzellangasse, we set an example for conscious consumption. Clothing and accessories changed hands in style - selected with heart and dedication.

We were also active internationally: “Hej” from Sweden! When visiting our InterGest partners, the culinary side of networking was on the agenda alongside professional exchange.

Many big and small celebrations will accompany us in 2022: On April 1, 2022, clan boss Liss Heller celebrates her 40th anniversary. (She was an early starter 😊!)

30 (+1) years of Heller Consult: there wasn't a big party this year, but the red confetti carpet was laid out in our hearts.

All good things come in threes: Heller Consult holding company InterGest®Austria turns 10 and InterGest Worldwide turns 50. As a partner of InterGest Worldwide, we support medium-sized companies from abroad with their expansion plans.

In November 2021, we launched our collaboration with Cointracking. Together we will guide you through the crypto tax jungle.

2020 was a year of great challenges, a year that went down in history. At the beginning of the year, we opened our office at Porzellangasse 49. Our former event space “Heller Consult Atelier” was converted into our new office premises and also extensively remodeled. A few weeks after moving in, “home office” was already on the agenda, as Covid reached Austria. No problem for the Heller Consult team. Thanks to journal services, video calls and the like, both external and internal communication went smoothly.

The first Heller Consult online program was launched in November: The Entrepreneur Starter Package.

After 13 years, it was time for Heller Consult to say goodbye: At the end of 2019, moving boxes were packed, many things were sorted out and reorganized. We changed our office premises and moved from Schubertring to Porzellangasse in the 9th district.

Online, online, online: That was probably our word of the year. Heller Consult was extremely active online in 2018 with webinars, videos, social media and email mailings. Our online program “Cryptos steuerlegal” was also launched.

However, analogue is still a must! This was clearly visible at our 2018 networking events “Wednesdays will be HELLER”. Topics ranged from data security in companies and corporate governance to the (potential) financial crisis.

Another special topic for us this year: the GDPR. Excellently prepared and still well informed - we were and still are!

The office in Pestalozzigasse is not suitable for larger events, and the question kept coming up: where to go? That's why Heller Consult purchased a spacious event and seminar room. Renovation work began shortly after the contract was signed. In just one month, everything had to be ready for the first Heller Consult event, the “Success Happening”. With a team of floor layers, plumbers, electricians and painters, we were able to transform the already relatively nice loft into a wonderfully fancy location. Together with interior designer and Heller Consult guest blogger Maria Husch, the loft was given that certain “Heller touch”. This is how the name Erfolgsatelier came about.

After extensive planning and strategy development, the Heller Clan Blog was launched in fall 2014. This blog is designed to explain tax terms in a simple way, provide an insight into our day-to-day business and familiarize entrepreneurs with news about tax changes and business management topics.
