We can approach our further expansion on a sound process foundation.”

After the very successful launch of the Weekend Supermarket at the Vienna location, the newly founded company go2market GmbH is entering the expansion phase.

These had to stand up to discussions with investors in all facets and underline the professionalism of the team.

Startup Negotiation Training

Startup Negotiation Training for 11 B2B Startups

How do I finance my startup, how do I get good collaborations and what tips and tricks are there for investor negotiations? These are topics that are of burning interest to all startup founders, and rightly so, after all, the financing of one’s own startup depends on many external factors and not only on the idea behind the startup. Therefore, ideal preparation for investor and cooperation negotiations is all the more important. As part of the 9th batch of the accelerator program Startup Wiseguys, one of the leading B2B startup programs in Eastern Europe, konsultori and key2investors (our online platform for professional preparation for investor meetings) together with the 11 selected startups of Startup Wiseguys dedicated themselves to all aspects that need to be considered in 2nd level negotiations in the startup negotiation training.

In 2012, Mr. Huber started his office HUBER GESTALTUNG, in which services from architecture, interior and corporate branding are offered fluently in combination.

Investor acquisition

Investor acquisition of an industry platform

To finance EUR 400,000 and the next expansion phase of an already excellently established industry platform, the founding team was looking for a suitable investor. There was still no expansion strategy and no argumentation for potential investors. The team was not yet sure whether a strategic investor was suitable at this point and what business angels would value as financial investors.

Architect Marketing

Architects marketing for an architectural firm

When the office was founded, it consisted of two people. They had successfully completed their first projects. The previous orders were brought to the team by word of mouth. In the third year after their foundation, the two approached me. Their goal was to address a larger circle of addressees and to be able to win customers away from word of mouth.

Strategy revision

Strategy Revision of a digital marketplace

The highly dynamic business environment of a digital marketplace requires the annual strategy review of the 8 business units. We carry this out more frequently as part of strategy review projects. Numerous changes occur on the customer side, as well as with the competition and new trends in the overall market. The management and the division heads wanted an external perspective. The assignment also included a moderated strategy process. The project involved defining the new direction and bringing it to the supervisory board for a decision. Over a period of 6 weeks, we worked with the individual divisions and at company level. Finally, we had to bring the results together.

Expansions Coaching

Startup Expansion Coaching: Interview with the “geometry gods” of Feasible.

Feasible brings complex geometries beyond orthogonality from the drawing board to manufacturing. As soon as geometries become more complex and structures no longer have right angles, manufacturing processes become difficult and expensive. With the help of the funding program “creative_project” of the Vienna Business Agency (a fund of the City of Vienna), Feasible and its project partner Rechenraum developed the software package ‘BOXER’: Non-rectangular structures can be brought into production without exploding costs.

Read the interview with the managing directors here about non-orthogonal geometries, what the future holds for manufacturing in the construction sector, and how they are approaching further expansion.
