About Us

Quiet confidence.
Measured decisions.

OGSA Partners was founded at Columbia Business School by George Alster and Omri Grynholc-Shoval, two classmates who chose to build their careers around one business, not a portfolio.

Our Approach

Complementary by design.

The strongest businesses are often built around years of technical knowledge, trusted customer relationships and a reputation that cannot be recreated overnight. Our role is not to replace that expertise, but to build around it.

We partner with owners and management teams who want to continue leading the work they know best. George and Omri take primary responsibility for the commercial, financial and strategic work around the business, while major decisions are made together.

Investment Philosophy

One business. A long-term partnership.

We are not building a portfolio and we do not invest with a fixed exit date. We intend to acquire one exceptional business, work alongside its owner and management team, and build it over many years.

That focus allows us to protect what already works: the people, customer relationships, culture and reputation. Where an owner wants to remain involved, we can create a structure that keeps their expertise at the heart of the company and allows them to participate in the value created together.

The Team

Meet the founders

George Alster
George Alster
Co-Founder & Managing Partner

George leads OGSA's commercial work: sourcing, relationships, and the search itself. Before OGSA, he spent four years at Baringa Partners in London, a strategy consultancy specialising in energy and infrastructure, where he rose from analyst to senior consultant and managed client relationships across the UK, the US, and Israel.

He has also built businesses of his own: a virtual private membership club spanning London and New York and a hygiene distribution company founded during the pandemic. He holds a First-Class MEng in Chemical Engineering from UCL and an MBA from Columbia Business School, where he was co-president of the Hospitality and Travel Association.

Outside of work, George plays as much tennis and golf as possible, only stopping to be the fun uncle to his five nieces and nephews.

Omri Grynholc-Shoval
Co-Founder & Managing Partner

Omri leads OGSA's operations and transaction execution. He spent four years at Harbor Group International, a global real estate private equity firm with over $21 billion in assets under management, where he oversaw the firm's Israeli investments end to end, from sourcing and diligence to negotiation and closing, and helped raise over $1 billion of capital. As part of his role, he led acquisitions of ownership stakes in real estate companies and subsequently partnered with management teams as an active shareholder, supporting strategic and operational initiatives.

Before his investment career, he served in the Israeli Intelligence Corps, where he received a Unit Honor of Excellence. He holds a BA in Economics and an MA in Financial Economics from Reichman University and earned his MBA from Columbia Business School in 2026, where he served as President of the Israel Business Association.

Away from work, he is an avid traveler, having visited more than 40 countries, and a lifelong sports enthusiast.

What We Look For

A high bar,
patiently applied.

We are looking for one established, profitable business in the UK or the US East Coast. Sector matters less than quality. These are the characteristics we weight most.

01

Recurring revenue

Contracted, repeat, or subscription income that makes next year's revenue knowable. Long customer relationships and low churn.

02

Essential services

Mission critical services customers cannot easily go without. Operationally embedded, and often required by regulation.

03

Fragmented industry

Markets with many small operators and no dominant national platform, leaving room for a careful owner to build.

04

Technical and operational depth

Deep technical knowledge supported by capable people who understand the work, the customers and the standards that make the business successful.

05

Consistent profitability

A record of steady profits through cycles. We are not a turnaround investor.

06

A partner-minded owner

An owner who cares about the company's next chapter and may want to remain meaningfully involved: leading the technical work, customers and team while sharing in the future value created.

What Happens Next

From first conversation to working partnership

Selling a business is a considered decision. The process should be too. Ours is simple, confidential, and moves at the owner's pace.

01

A first conversation

Confidential and without obligation. We want to understand the business and what its owner wants from a transition.

02

Getting to know the business

We sign an NDA, review information, and ask considered questions. We do not waste an owner's time.

03

An offer in writing

If there is a fit, we set out our valuation and terms plainly in a letter of intent, and complete diligence efficiently.

04

Designing the partnership

Together, we agree what the owner wants to keep leading, where OGSA can add the most value, how decisions will be made and how everyone participates in the company's future success.

Get In Touch

Want to keep building, not simply step away?

If you have built a strong business and would value a partner to help with the commercial, financial and strategic work around it, we would be glad to start a confidential conversation.

If you are an intermediary with a mandate, or simply want to learn more, we are always happy to talk.

Every enquiry is read by the founders

There are no automated replies and no gatekeepers. You will hear directly from George or Omri within 24 hours.

All enquiries are treated with complete confidentiality. We sign NDAs at any stage of the conversation.
