Operational AI Advisor · Fractional Chief AI Officer
Rhiza helps founders, CEOs, and operating leaders identify where AI can create meaningful value, move the right initiatives into production, and build the leadership and operating capability needed to scale.
For organizations with real operating complexity, meaningful AI and data investment already in motion, and no single leader owning the path from activity to measurable value.

The Thesis
The pilots work. The demos impress. The model is rarely the constraint.
Value appears when AI is connected to a meaningful business decision, embedded in a real workflow, owned by the right leaders, and measured against an outcome that matters. That layer is the operating system of the business, and it is where most AI programs stall.
Reaching it requires more than technology. It requires business focus, operating discipline, and senior leadership across the full path from opportunity to execution.
The Moment
Most organizations already have more AI possibilities than they can pursue. The challenge is deciding where to focus, determining what is genuinely feasible, establishing clear ownership, and moving from experimentation to a capability the business can rely on.
Teams are pursuing disconnected use cases without a shared view of business value, feasibility, or strategic importance.
Experiments show promise, but stall before production because the workflow, ownership, data, or operating model is not ready.
AI spending is growing faster than the organization’s ability to explain what value it is creating or how that value will be measured.
Business, technology, data, and functional teams each own part of the work, but no leader owns the complete journey from opportunity to measurable outcome.
Left alone, none of this resolves on its own. It compounds. The spend keeps climbing, the leverage stays locked up, and the value story stays thin at exactly the moment it matters most: the next raise, the board review, the exit. The organizations that pull ahead do not run more pilots. They put AI to work inside the operating system of the business.
Where Rhiza Fits
Rhiza works across strategy, operating model, data, technology, and execution, connecting decisions that are usually divided across separate teams. The objective is not another AI roadmap: it is the focus, ownership, and operating path required to turn the right opportunities into measurable capabilities.
Identify the small number of AI opportunities with the strongest combination of business value, feasibility, strategic importance, and speed to impact.
The result: fewer disconnected experiments and greater confidence in where to invest.
Translate a promising use case into a practical operating plan spanning workflow, data, technology, ownership, governance, adoption, and measurement.
The result: a credible path from idea to a capability the business can use.
Establish the operating model, decision rights, leadership cadence, and governance needed to scale AI beyond a single successful initiative.
The result: an organization that becomes better at turning AI opportunities into business outcomes.
How It Works
Every engagement begins by clarifying what should improve in the business and what decisions, workflows, or products must change to create that value. Technology is evaluated in service of that outcome, not treated as the strategy itself.
Clarify the business problem, decision, workflow, or customer outcome that needs to improve.
Establish what success would mean and how the organization will recognize measurable progress.
Assess the use case across value, feasibility, data readiness, operating complexity, economics, risk, and speed to impact.
Separate compelling opportunities from attractive distractions.
Define the business owner, decision rights, delivery roles, governance, and leadership cadence required to move the work forward.
Make accountability explicit before complexity increases.
Work alongside internal teams and partners to shape delivery, resolve cross-functional barriers, support adoption, and measure results.
Build internal capability so progress does not depend on the advisor indefinitely.
Selected Outcomes
Across leading global organizations, the through-line is the same: data and AI turned into operating systems that create measurable value and survive scale.
AI-Enabled Product Growth
~12×
estimated revenue run-rate growth
For a Series B connected-products company, built production AI and recurring-revenue infrastructure that helped support 12× growth in annual revenue run-rate and strengthened acquisition readiness.
Predictive Risk Management
~$10B
gross fixed-income book
Built the predictive risk platform for the retail fixed-income operation within Morgan Stanley, automating pricing, exposure, and hedge decisions across a ~$10B gross book, and developed an algorithmic U.S. Treasury bond arbitrage system supporting approximately $300M in cumulative face value.
AI Economics at Scale
91%
operating cost reduction per device
Re-architected a connected-product AI pipeline from costly batch processing to live/on-device inference, reducing monthly operating cost by approximately 91% per device and making the revenue model economically scalable.
The Engagement
Rhiza is designed for organizations that need senior ownership and practical momentum now, but may not need another full-time executive or a large consulting team. Engagements begin with a focused business question and expand only when there is meaningful value to pursue.
Operational AI Diagnostic
Clarify where to focus.
A concentrated assessment of the highest-value opportunities, current constraints, organizational readiness, and the practical path forward.
Best for: AI activity exists, but priorities, value, ownership, or the execution path are still unclear.
Principal outputs
Engagement shape
A focused, time-boxed engagement concluding in a 90-day action plan.
Fractional Operational AI Leadership
Move priority initiatives toward value.
Embedded fractional leadership delivered through focused execution cycles. Rhiza works alongside business leaders, internal teams, and external partners to establish ownership, guide delivery, remove cross-functional barriers, and connect the work to measurable outcomes.
Best for: AI is strategically important and you need senior operating guidance, without adding a delivery team.
Principal outputs
Engagement shape
Typically begins with a focused 90-day value-realization phase, then continues in execution cycles.
Strategic AI and Data Oversight
Sustain direction as the capability scales.
Ongoing executive or board-level advisory for organizations that need experienced judgment, operating oversight, and strategic continuity without a full-time role.
Best for: Internal ownership exists, but leadership still needs executive guidance, value oversight, or board and investor narrative support.
Principal outputs
Engagement shape
Ongoing senior judgment as the capability matures, at a cadence set with leadership.
Rhiza works with your existing leaders, teams, and partners, not around them and not in place of them. The objective is measurable progress and stronger internal capability, not long-term dependency.
A Good Fit
Rhiza is best suited to founder-led, scaling, mid-market, and PE-backed organizations where AI is becoming strategically important but the path from interest to business value remains unclear.
Staff augmentation, generic AI training, isolated technical implementation, or large transformation programs built around consultant headcount.

About Chris
I’m Chris Tambos. For 30+ years I’ve helped organizations turn emerging technologies into operating capabilities and measurable business outcomes, across early algorithmic decision systems, commercial natural language processing, AI-driven commerce, connected products, industrial AI, and enterprise-scale data and AI leadership.
Across each generation of technology the challenge has been remarkably consistent: connect technical possibility to a business problem that matters, build the organizational capability required to act, and measure whether the work changed the outcome. I’ve done that from inside the organizations responsible for delivering the results, not from outside them.
Rhiza is the Greek word for root. It’s a deliberate choice: what shows above ground, growth, margin, enterprise value, is determined by the system beneath the surface that no one sees. Most companies try to grow the visible part. I build the operating intelligence underneath it, where the leverage compounds.
Start With the Decision
A practical discussion about the opportunity, bottleneck, or decision that matters most to your organization: whether there is a credible path to value, what may be standing in the way, and whether Rhiza is the right partner to help move it forward.
A focused executive conversation. No generic AI pitch.
