Background

Evan Stein is a Partner at Union Park Capital, a Boston-based private equity firm focused solely on lower middle-market Industrial Technology companies. He joined Union Park in 2016 and focuses on leading new later-stage and buyout investments in industrial technology markets.

At Union Park, Stein is actively involved with and currently serves on the boards of KPM Analytics, Process Insights, Advanced Environmental Monitoring, Exaktera, Spheros Environmental, and CFS Technologies. His work includes both new investment execution and portfolio-company support, including organic growth and add-on acquisition strategies. Union Park says he has worked on more than 25 industrial technology acquisitions across the U.S. and Europe.

Before Union Park, Stein was an investor at Battery Ventures, where he sourced, evaluated, and executed middle-market buyout transactions in industrial technology and industrial software. Earlier in his career, he held roles at Piper Jaffray and Boston Consulting Group.

Stein graduated from Northeastern University’s D’Amore-McKim School of Business with a B.S. in business administration, concentrating in finance. Union Park announced his promotion to Principal on July 1, 2020, and to Partner on May 24, 2022.

Investment Thesis & Focus

  • Union Park is not an angel or seed investor based on its current public materials; its stated focus is lower middle-market Industrial Technology private equity.
  • The firm targets the “smarts” of the industrial process: application-specific products and services used in technical industrial environments.
  • Union Park looks for businesses with durable revenue, protected niches, deep application knowledge, long operating histories, and recurring spares, repairs, or consumables revenue.
  • The firm’s stated approach is long-term value creation, with value created through “profitably growing a business, not financial engineering.”
  • Union Park partners with management teams on product innovation, commercial excellence, geographic expansion, and strategic add-on acquisitions.
  • The firm will consider profitable companies and historically profitable companies that are temporarily underperforming.
  • Transaction fit includes family-held businesses, ownership liquidity, acquisition financing, management buyouts, recapitalizations, take-private transactions, growth equity, and succession situations.
