Beringea operates as a transatlantic investor, with teams in both the UK and the US. Each team focuses on its local market, but the structure is designed to support portfolio companies as they scale internationally.
For UK founders, this becomes most relevant when thinking about expansion into the US. It is a large and complex market, and early decisions can shape long-term outcomes. Our US team provides local insight, relationships and execution support that help reduce that risk.
Below, we provide an overview of the US investment team, their focus, and how they work. This is the first in a series of features on the Beringea US team.
How the US team fits into the broader platform
Beringea US is Beringea’s American investment business, headquartered in southeast Michigan. The team manages several active venture and growth capital funds investing in growth-stage companies across the United States.
The US funds focus on $2m-$10m preferred equity investments in businesses which have moved beyond early proof points and are ready to scale. While the team invests nationally, there has historically been an emphasis on the Midwest, a region with deep technical talent, capital-efficient businesses and a growing number of ambitious founders.
In terms of what the US team looks for, the fundamentals are consistent:
- A proven business model addressing a large and growing market
- Strong commercial traction, often reflected in ARR of $3m+
- Scalable financial and operating metrics
- A defensible product or technology with clear differentiation
- An exceptional management team with clarity of vision and ambition
Beringea US typically invests at Series A, Growth, or later stages, partnering with founders as they move from validation to sustained scale.
The US investment team
The US investment team is led by Charles (Charlie) Rothstein, Founding Partner at Beringea.
Charlie oversees all US fund activity and sits on the boards of several portfolio companies. He is also deeply involved in supporting entrepreneurship and economic growth in the Midwest, both through his work at Beringea and through his involvement with public and non-profit organisations in Michigan.
Alongside Charlie, the team includes Michael Gross (Managing Partner), William Blake III (Partner) and Ben Bernstein (Principal). The team brings experience across venture and growth investing, with a strong track record of supporting companies through scaling and exit.
Experience from the US market
Beringea US has backed a diverse group of growth businesses across multiple sectors.
A few examples include:
- Authenticx, a SaaS platform that combines human insight with automated analysis to help healthcare and service organisations better understand customer interactions and improve decision-making.
- Optilogic, an enterprise SaaS business that helps companies design, optimise and operate complex supply chain networks using advanced analytics and optimisation technology.
- Micro-LAM, an industry leader in precision manufacturing, which was backed by Beringea US and acquired in 2025 for more than $100m, demonstrating the team’s ability to support companies through to realisation.
These companies reflect the type of businesses the team supports and the outcomes they work towards.
How this supports UK portfolio companies looking to expand internationally
The transatlantic structure is designed to be practical for founders, not just a label.
For UK portfolio companies, Beringea US can support in several ways:
- Strategic insight: sharing market data, sector experience and practical lessons from companies already operating in the US.
- On-the-ground introductions: access to trusted lawyers, accountants and advisers to support US market entry and expansion.
- Co-investment: US funds have co-invested alongside the ProVen VCTs to back portfolio companies expanding into the US.
- Commercial introductions: connections to US corporate customers and decision-makers that can translate into early commercial traction.
- Access to US capital markets: support for companies looking to raise follow-on funding from US investors, where pools of capital are deeper and later-stage rounds are often larger.
This support is most often used when a company is entering the US market, but it can also be valuable earlier in shaping strategy or later when scaling operations.
For UK founders with ambitions to grow internationally, having a team already embedded in the US market - with the relationships, sector knowledge and capital to back it up - is a meaningful advantage at every stage of that journey.
