and Precision
A FINRA-licensed M&A advisory firm delivering institutional-quality execution for companies and investors across the lower-middle market.

A Firm Built on Professionalism & Real Partnerships

We prioritise preparation and communication, helping clients understand their options and move confidently through each stage of the process. Our approach is defined by measured decision-making, real market awareness and a long-term view of what success means for the owners and investors we serve.
Our Mission
Our mission is to empower lower middle market companies with thoughtful sell-side, capital raising, and buy-side advisory solutions, helping businesses unlock value and navigate critical growth and transition moments.

Expertise Where It Matters Most
We specialize in advising companies, typically between $1–$20 million in EBITDA, with deep experience in consumer, industrial, residential services, business services and niche manufacturing sectors. Our advisory work spans three core areas:
Sell-Side Advisory
Competitive, well-structured processes designed to maximize valuation and fit.
Capital Raising
Equity and debt solutions tailored to each company’s growth or liquidity priorities.
Buy-Side Advisory
Strategic acquisition support, from sourcing through diligence and closing.
Across every engagement, clients experience:
Hands-on, responsive support from the deal team.
Strategy shaped around their priorities, not a template.
A regulated, credible investment banking process.
Insights informed by real market conversations and relationships.
