Who is Seilern?

We are an independent, privately-owned investment manager focused on investing in the purest quality growth companies.

With a belief that investing in only the best companies can achieve enduring returns, Peter Seilern established Seilern Investment Management ltd in its original form in 1989.

While we have enhanced our process over the years, we have remained patient, long-term investors.

Focused on building lasting portfolios

Independently minded

We interrogate and debate to find the right answers – even if this goes against established wisdom.

Immersive insight

We take our time to understand completely and build independent insight.

Intellectually tenacious

We seek to continually refine and improve our process, enhancing our clients’ portfolios.

Process-driven

Our robust process drives our investment selection. We do not compromise on following the ten golden rules.

Long-term

We aim to preserve and grow our clients’ capital over the long term – not to make quick profits.

The investment philosophy

The team

Our people are our strongest asset to help bring success for our clients. This is underpinned by a powerful collegiate belief in quality growth investing.
