Personalised transaction advice and execution.
For entrepreneurs and businesses. For start-ups and financial investors.

We accomplish more.
For you – and your future.

With more than 15 years of experience in the field of transactions and strategy, we fully understand the provider and customer sides of standardised advisory offerings – and their limitations.

LSJ goes further. Flexible, personal, independent. Entrepreneurial thinking and action. For customers who want more.

M&A Advisory

We support you from your first negotiations of an acquisition and sale of a company or shareholdings all the way to the successful closing of a deal.

Strategic Advisory

We are advisors, supporters and mentors: for market entry, growth, portfolio optimisation or sparring for managers and companies.


LSJ stimulates growth and helps shape your future – providing analysis, structuring and implementation of equity capital measures.

We create values –
with values.

We operate independently, dynamically and in close proximity to our customers, with an affinity for medium-sized businesses and place the focus where it should be: on your satisfaction and your success.
