I.
A former CxO runs the engagement.
Not consulted to the function. Not briefed on the function. Ran it, under pressure, with the same constraints the buyer is under now.
Vol. I · The operator-led, AI-native execution firm
Modus operandi—
the way operators work.
Every engagement at Modus is run by a former CxO who has actually run the function. AI runs the labor underneath. The change ships in weeks, not quarters.
§ I · Principle
The most consulting engagements end with a deck.
Ours end with the change.
A mid-market CEO has a value-creation plan and a quarter to move it. The big firms send a partner to win the deal and a 26-year-old to run it. The boutiques write a strong memo and go home. The AI shops ship a model run by people who have never defended one in a board meeting. Each is excellent at half the job. None does the whole.
We built Modus against that half-measure. Every engagement here is run by a former CxO who has actually run the function — a former CIO leading the CIO work, a former CFO running the close, a former CMO inside the brand re-launch, a former CHRO running the culture reset, a former COO redesigning the operating model. Not consulted to the function. Run it.
AI is how we ship. Experience matched by technology. AI does the labor; the operator does the judgment. Discovery, analysis, code, change-management collateral, segmentation, close mechanics — compressed by tooling so the operator's judgment is what the engagement costs you, not the labor underneath. That is AI speed: weeks not quarters, decisions made not studied, change shipped not recommended.
The most human firm wins the age of AI. Ours is the firm where the human is a former CxO and the AI is the execution layer underneath.
§ II · Practice
Three commitments. No exceptions.
II.
AI runs the labor underneath.
Modern AI and automation are how the work gets done — not a service line we sell, and not the thing in the room making the call. AI does the labor; the operator does the judgment.
III.
The deliverable is the change.
Not a report. Not a roadmap. Not a steering committee deck. The integration shipped, the brand re-launched, the close on time, the seat filled. We scope to outcomes.
§ III · The Operators
A bench of former CxOs. One firm.
Thirteen-plus decades of senior-executive experience. Fifty-plus operators recruited from operating roles, not from consulting. The principal who scopes the engagement is the principal who runs it.
Humberto Castillo
CEO · Founder
Operator-grade CEO running the firm. Built the bench, runs the firm, signs the engagement letter.
Walt Carter
President · Former CIO
Three digital transformations in financial services. Implemented 20+ enterprise software programs before joining the firm. He's not learning from your CIO; he was your CIO.
Marty Smith
CGO · Growth Operator
Operator-grade go-to-market and growth leadership. Runs CMO-adjacent work: brand, demand, commercial transformation.
Bill Price
CBDO · Operator
Business development from an operator's seat, not a partner's. Sources, scopes, and runs the engagement to land.
§ IV · The Surface
Seven service lines. One firm. One bill.

The same principal who scopes the strategy can pull in the security operator, the interim CFO, the brand and growth lead, the workforce planner, and the data lead without re-onboarding.

"What's the fixed fee, and what's the deliverable I can put in front of the audit committee on date X? I'm not buying hours. I'm not buying a discovery. I want a number, a date, and a name on the engagement letter."
§ VI · Engage
Start a conversation with a former operator.
A 30-minute call with the principal who would run your engagement. No analyst on the line. No deck.
