Discovery & mandate
We learn the business and define the outcome. Every later decision is measured against that definition.
Mergers & Acquisitions
Exceptional businesses, precisely placed.
Sell-side and buy-side advisory for founder- and family-owned companies. Confidential, partner-led, from first meeting to close.
0%
No engagement fee, no success commission. 100% of the agreed proceeds go to the seller.
Engagement terms are set out in writing, in full, before any work begins.
How we work
Four phases,
one defined outcome.
Positioning & outreach
A curated set of qualified buyers, approached one at a time, on terms the owner has approved.
Negotiation & diligence
Competing interest is managed, not collected. Structure and diligence keep leverage on the seller's side through signed terms.
Close & transition
Through completion and into a clean handover — for the team, for customers, for whatever the owner does next.
The weight behind a process.

Start the conversation
Every transaction begins
with a private conversation.
Whether you are preparing a confidential sale or searching for a specific acquisition, the ONYX partners would welcome the conversation.
Investing rather than transacting? ONYX also opens late-stage pre-IPO positions to qualified investors.
