SEIL PRIVATE OFFICE is the entrepreneurial investment arm of the Seil Group.
We act as an investor, operator, and joint venture partner in select real estate and investment structures, with a clear focus on undervalued, structurable assets. Our approach is entrepreneurial: We invest our own capital, structure financing, assume operational management, and develop properties with a clearly defined exit strategy.
OUR APPROACH:
We identify opportunities with value creation potential – be it through repositioning, new leasing, restructuring, or strategic realignment – and bring together capital, structure, and management. In doing so, we assume not only the role of capital provider but also that of active asset manager and strategic operator.
In joint venture structures, we collaborate with family offices, entrepreneurs, institutional investors, and international capital partners. We structure investment models with clear governance, transparent risk distribution, and a defined exit strategy.
Our focus is not on short-term project development, but on controlled value creation, stabilization and institutional usability.
SEIL stands for discreet capital allocation, operational excellence and entrepreneurial responsibility – with its own risk, commitment and clear performance orientation.
The company operates in the following business areas:
Direct Investments
direct investments in real estate
Joint Ventures
structured partnerships for short-, medium- and long-term real estate projects
Club Deals
Formation of selected investor groups for specific individual real estate projects
Private Equity
Our equity capital is specifically invested in companies or assets to actively increase their value.
SEIL PRIVATE OFFICE sees itself as an entrepreneurial investment partner with its own capital, a clear vision, and a long-term perspective. We invest selectively, take responsibility for implementation, and combine strategic structuring with operational management – always with the aim of creating substance rather than simply moving capital.
Our roots lie in real estate brokerage. This is precisely why we understand how to reconcile diverse interests, realistically manage expectations, and create sustainable structures. We don't think in terms of one-sided advantages, but rather in long-term partnerships – because only balanced structures lead to stable results.
For approximately 15 years, we have been structuring investments, supporting acquisition and sales processes, and assuming responsibility as both investor and operator throughout the entire life cycle of an asset. In doing so, we combine capital, strategy, and operational management with clearly defined governance and exit structures.
SEIL PRIVATE OFFICE collaborates with entrepreneurs, family offices, and institutional capital partners. Integrity, reliability, and high ethical standards form the basis of our actions – at every stage of an investment.

(Frankfurt am Main, October 2022) SEIL REAL ESTATE (SRE), the real estate management boutique for institutional and private high-net-worth investors, is committed to modernity and progress not only in its consulting and client services, but also in its human resources. As one of the first in its sector, the Frankfurt-based company is taking a radical step towards a better work-life balance for its employees by giving them every fourth Friday off, effective immediately.
Maximilian Seil, Managing Director of SRE: “If we want progress in the industry, we have to start with work-life balance. This applies both to our daily real estate business and to how we interact with each other within our team.” The prerequisite is that it benefits everyone involved: “We are convinced that 12 additional days off per year, giving our employees 12 long weekends, will have a positive effect – primarily on their well-being, but ultimately also on SRE itself. Because when employees feel balanced at work and in their private lives, this always has a positive impact on daily business,” Seil continued.
The company restructured in April, expanding its management team with the addition of Executive Advisor Nino Grubisic MRICS (STOA GmbH) and rebranding to further sharpen its positioning. It also recently joined the DGNB, the German Sustainable Building Council.
Nino Grubisic adds: “Both trials by individual companies and studies demonstrate that reduced working hours have a positive impact on employee satisfaction and well-being. Although less time is available, the perceived workload decreases and productivity often even increases. With this step, our company aims to further distance itself from outdated ideas and actively shape the future of work for the benefit of everyone.”

(Frankfurt am Main, July 25, 2022) Frankfurt-based real estate boutique Seil Real Estate (SRE) acted as sell-side advisor to the TM Property Group on the sale of a historic building project in a prime location. The property, built around the turn of the 20th century, is located on Mainluststrasse, directly adjacent to the banks of the Main River in Frankfurt. The historic building currently comprises nine units and approximately 1,000 square meters of leasable space.
SRE had already acted as buyside advisor for TM Property in the acquisition of the property and, together with them, as project partners, oversaw the concept and development phase. TM Property, with the involvement of the historic preservation authorities, obtained a building permit for the conversion into spacious apartments, and the concept envisioned the sale of luxurious apartments in the historic building as well as the penthouse. However, after the building's interior had been gutted, a buyer was identified for all units, and the sale was finalized with this buyer.
“Thanks to our origins in Wiesbaden, we are intimately familiar with the potential of older buildings and knew that this would work particularly well in this prime location. After renovation, the buyer will own an outstanding property in a top location in Frankfurt am Main. This transaction demonstrates that we can find the right solutions even in these times,” says Nino Grubišić, Executive Advisor at SRE.
The exact purchase price of the property was not disclosed, but it was in the high single-digit millions. The buyer is a private individual and the seller a subsidiary of the TM Property Group from Wiesbaden.
