Our clients







What it is. A leadership advisory firm that also delivers retained executive search. Search is one implementation capability, not the business model.
Who it's for. CEOs, founders, boards, and investors at Series A to pre-IPO B2B SaaS companies in MarTech, eCommerce, Composable Commerce, Supply Chain SaaS, and Enterprise AI.
What it delivers. Leadership decisions that hold: the right GTM leaders, and an honest read on the teams already in the seat.
We build the mandate before we build the slate.
- 1
The mandate.
Business context, first-year outcomes, failure modes, the team to be built, and board expectations, agreed before recruiting starts.
- 2
Motion before profile.
We define how this role must sell, market, or serve before deciding who could do it.
- 3
Short slates.
We submit short. Volume submission moves the screening burden onto your calendar, and executive attention is the scarcest thing you have.
- 4
After the hire.
Structured check-ins through the first months, so issues surface while they are still easy to fix.
Cognitive Fit Assessment.
Kolbe, a licensed third-party instrument, gives a read on how a candidate instinctively approaches problems and execution. It is one input to a human decision, never a screen or a cutoff.
Human judgment throughout.
Every advancement decision is made by a person.
How we help
Leadership advisory
What clients say
“For go-to-market hires, first, you have to define what experience you want to deliver to customers. Second, you assess whether a candidate can deliver that experience -- ideally in ways you never even imagined. Third, you confirm that your company can provide that candidate the challenge and opportunity she/he seeks. … Darrell understands all of these steps.”
“Given the strength of his network, it's clear why so many retail software companies trust him with executive searches. Darrell doesn't just know the key players; he understands the nuances of the retail tech business and exactly what's required to succeed, no matter the category or niche.”
“Darrell's knowledge and connections in the MarTech world were extremely helpful from securing a board member to identifying and approaching alliance partners to formulating business strategy. He is a true asset to any startup founder”
