Hong Kong Fractional CTO & Senior Advisor
Senior cloud, data, and AI leadership for Hong Kong companies
Helping leadership teams make better decisions on cloud architecture, data platforms, AI adoption, and vendor selection without a full-time senior executive.
Most engagements start with a Diagnostic Sprint: a fixed-scope review delivered as a written report with clear recommendations and next-step options.
When to Bring in Fractional Leadership
Cloud spend is rising, but architecture confidence is low
Costs are increasing, but the team lacks confidence to assess whether the current architecture is appropriate for the next stage of growth.
Data is fragmented and decisions are delayed
Business data is scattered across systems, reporting is slow, and there's no clear path to consolidation or meaningful improvement.
AI is on the agenda, but roadmap and business case are unclear
Leadership wants to explore AI, but lacks the internal expertise to separate realistic value from vendor hype or develop a credible plan.
Major vendor decisions move forward without enough internal technical challenge
Platform evaluations and major vendor decisions move forward without anyone internally positioned to challenge recommendations or validate technical claims.
How Engagements Work
Structured advisory and leadership support for companies that need senior technical judgment without a full-time hire.
Diagnostic Sprint
A fixed-scope engagement for architecture review, cloud cost assessment, AI opportunity framing, data platform evaluation, or vendor assessment. Delivered as a written report with actionable recommendations.
Typical engagement: 2-3 weeks · fixed fee
For companies that need clarity and direction before committing to broader advisory work.
Monthly Advisory
Regular strategic input on cloud, data, AI, and architecture decisions. Structured as a monthly retainer with scheduled sessions and ad-hoc access for urgent questions.
For companies that need consistent senior technical judgment without a full-time commitment.
Fractional Leadership
Senior involvement in roadmap planning, architecture decisions, team guidance, delivery oversight, and executive decision support during periods of transition or scale.
For companies that need senior technical leadership during critical phases but don't require a full-time CTO.
Ideal fit
Hong Kong SMEs, growth-stage companies, and established firms facing cloud, data, or AI decisions where senior judgment matters, and a full-time CTO is not the right cost or commitment yet.
Not a fit
Hands-on coding staff augmentation, build-from-scratch agency delivery, or earliest idea-stage teams without budget for senior advisory. WazoTek is advisory and oversight: implementation stays with your team or selected partners.

Frequently Asked Questions
What does a fractional CTO or senior advisor actually do?
We provide senior technical judgment and leadership support for cloud, data, and AI decisions without the cost and overhead of a full-time hire. This includes architecture reviews, vendor evaluation, roadmap planning, team guidance, and decision support for important technology choices.
How is this different from hiring a full-time CTO?
A fractional engagement provides access to senior-level experience without the cost and commitment of a full-time hire. This works well for companies that need strategic technical leadership but don't require someone in the role full-time, or for companies facing major technology decisions that benefit from outside expertise.
How is this different from a software agency or contractor?
WazoTek focuses on advisory, decision support, and technical oversight rather than hands-on delivery or staff augmentation. We help you make better decisions, evaluate options, challenge vendor proposals, and set technical direction. When implementation is required, we help structure the work, select partners, and provide oversight, but execution itself is handled by your team or selected partners.
What kinds of Hong Kong companies are the best fit?
Companies that need senior technical judgment for cloud, data, or AI decisions but don't have that expertise in-house. Typically SMEs, growth-stage companies, or established businesses planning technology modernization. Best fit is leadership teams facing major technology decisions where getting it right matters.
How do engagements usually begin?
Most engagements start with a diagnostic sprint: a fixed-scope assessment focused on a specific challenge such as cloud cost optimization, architecture review, or AI roadmap framing. This provides immediate value and clarity before committing to ongoing work. Many companies then move to a monthly advisory retainer or fractional leadership arrangement.
Are implementation services included?
WazoTek focuses on advisory, decision support, and technical oversight rather than hands-on execution. When implementation is required, we help define requirements, evaluate vendors or contractors, and provide oversight during delivery. Implementation itself is handled by your internal team or selected partners.
How is pricing determined?
A typical Diagnostic Sprint runs 2-3 weeks as a fixed-fee engagement. Advisory retainers are structured as fixed monthly fees. Fractional leadership engagements are scoped based on required involvement and duration. Exact fees are confirmed after a short diagnostic call to ensure fit and scope clarity.
Where are you based and who do you work with?
WazoTek is based in Hong Kong and prioritizes work with Hong Kong companies and leadership teams. This allows us to provide responsive in-person support when needed and stay close to the local business context and work in the same time zone as client teams.
