Services
Where we go deep
Every engagement starts with understanding your problem. These are the areas where we have the deepest experience - and most real work spans more than one.
Fractional CTO
A fractional CTO is a senior technology executive who works with your company on a part-time or contract basis, providing the same strategic leadership as a full-time CTO at 60–80% lower cost. If you have a product vision and early traction but no technical co-founder, we step into the CTO role - making architecture decisions, conducting technology due diligence, evaluating vendors, planning your product roadmap, and hiring your first engineers. From system design to engineering org structure, we cover the full CTO remit.
Who it's for
- Non-technical founders who need a technical partner
- Scale-ups that have outgrown their initial technical setup
- Companies between CTOs who need continuity
What you get
- Clear technology roadmap aligned with business goals
- Architecture that scales with your growth
- Confident technical decision-making without a full-time hire
- Engineering team structure and hiring strategy
Technology Strategy
Technology strategy is the discipline of aligning technical decisions with business objectives. We advise founders, leadership teams, and boards on the choices that shape their business - from stack selection and cloud architecture to scaling strategy and build-vs-buy trade-offs. Every recommendation is grounded in over 15 years of experience building production systems across ecommerce, fintech, and telecommunications, including technology due diligence for investment and acquisition.
Who it's for
- Leadership teams making critical technology decisions
- Founders evaluating technical approaches or vendors
- Boards needing independent technical due diligence
What you get
- Technology strategy aligned with business objectives
- Vendor and platform evaluations you can trust
- Technical due diligence for investment or acquisition
- Build-vs-buy analysis backed by real-world experience
Automation & AI
AI is everywhere, but most of it is noise. We cut through the hype and implement workflow automation, LLM integration, and intelligent process orchestration that actually make a difference to your business. Whether it's automating repetitive processes with RPA, building retrieval-augmented generation (RAG) pipelines, or integrating AI into your existing systems - we focus on practical adoption that delivers measurable results. Based on our experience, most businesses can automate 20–30% of manual tasks with current technology - the challenge is identifying which ones deliver the highest ROI.
Who it's for
- Companies with manual processes ripe for automation
- Teams looking to integrate AI into existing workflows
- Businesses that want practical AI, not proof-of-concepts
What you get
- Automated workflows that eliminate repetitive manual work
- AI integrations that enhance existing systems
- Clear ROI on every automation investment
- Team training and documentation for ongoing use
Small Business Technology
Small business technology consulting helps companies replace manual processes with connected, efficient systems. Spreadsheets everywhere, manual data entry that eats hours, disconnected tools that don't talk to each other - the average small business loses significant productivity to these inefficiencies. We meet you where you are and move you forward pragmatically: business intelligence dashboards, CRM implementation, workflow automation, and the right SaaS tools set up properly with your team trained to use them. No enterprise software you don't need, no jargon, no overengineering.
Who it's for
- Small businesses running on spreadsheets and manual processes
- Companies that know they need technology but don't know where to start
- Teams drowning in disconnected tools
What you get
- Connected systems that replace manual data entry
- Business intelligence dashboards on your existing data
- Automated workflows for repetitive tasks
- A technology roadmap sized for your business
Backend Architecture
Backend architecture consulting covers the design and implementation of scalable, resilient server-side systems. Building reliable systems is hard - building reliable systems around unreliable third-party services is harder. We specialise in designing and building backend architectures that scale, with deep expertise in RESTful and event-driven API integrations, microservices orchestration, complex integration ecosystems, and the edge cases - race conditions, cascading failures, retry storms - that only surface in production.
Who it's for
- Companies with complex integration requirements
- Teams scaling systems that weren't designed to scale
- Businesses managing multiple third-party API dependencies
What you get
- Resilient architectures built for real-world conditions
- API integrations that handle edge cases gracefully
- Scalable systems built around non-scalable parts
- Technical documentation and runbooks for your team
Data Engineering
Data engineering is the discipline of designing, building, and maintaining the systems that collect, store, and transform raw data into usable business intelligence. We build data pipelines, ETL/ELT processes, data warehouse architectures, and analytics infrastructure that turn messy, real-world operational data into clear business insights. From admin dashboards to reporting tools to full analytics platforms - we've built the systems that help teams make data-driven decisions with the data they already have.
Who it's for
- Companies sitting on valuable data they can't easily access
- Teams that need internal dashboards and reporting tools
- Businesses building analytics capabilities from scratch
What you get
- Data pipelines that reliably move and transform your data
- Dashboards and reporting tools built for your workflows
- Analytics infrastructure your team can maintain and extend
- Data-driven decision making across the business
Team Building & Hiring
Engineering team building is the process of designing, hiring, and scaling a high-performing development organisation. It's about more than posting job ads - we help you define roles and career frameworks, design structured interview processes, build technical assessments, and establish the engineering culture that attracts and retains strong engineers. Whether you're hiring your first developer or scaling from five to fifty, we've built eight engineering teams from scratch and can guide you through it.
Who it's for
- Founders hiring their first engineers
- Companies scaling their engineering organisation
- Teams that need to restructure or level up
What you get
- Clear role definitions and career frameworks
- Interview processes that identify the right people
- Team structures that support your engineering goals
- Engineering culture that retains talent
Frequently Asked Questions
Common questions
A fractional CTO is a senior technology executive who works with your company on a part-time or contract basis. They provide strategic technical leadership - architecture decisions, technology roadmaps, vendor evaluation, and engineering team building - at a fraction of the cost of a full-time CTO hire. Companies typically engage a fractional CTO when they need senior technical direction but aren't ready for a full-time executive.
A fractional CTO typically costs 60–80% less than a full-time CTO hire when you factor in salary, equity, benefits, and recruitment fees. Engagement models vary - from embedded advisory (regular weekly involvement) to monthly retainers for strategic guidance. The right model depends on your stage, complexity, and how much hands-on technical leadership you need.
Startups typically benefit from a fractional CTO when they have product-market fit or early traction but no technical co-founder, when they're making critical architecture decisions that will affect scalability, when they need to hire their first engineers and want to get the team structure right, or when they're raising funding and need credible technical leadership for due diligence.
A technology consultant typically delivers recommendations and leaves. A fractional CTO embeds in your team, takes ownership of technical outcomes, and stays engaged over months or years. They attend your standups, review your pull requests, interview your engineering candidates, and are accountable for the technology strategy - not just advisory.
Xethos has deep experience across ecommerce, fintech, telecommunications, and SaaS. We've built systems handling thousands of daily transactions, designed architectures for regulatory compliance including SOC 2, and integrated hundreds of third-party APIs. Our approach adapts to any industry where technology decisions drive business outcomes.
Yes. While Xethos is based in Cape Town, South Africa, we serve clients across South Africa, the United Kingdom, and the European Union. Our GMT+2 timezone is only 1–2 hours ahead of the UK, making real-time collaboration straightforward. We work remotely with structured communication cadences tailored to each client's needs.
A technology strategy engagement starts with deep listening - understanding your business goals, current systems, team capabilities, and constraints. We then deliver a clear technology roadmap covering stack recommendations, architecture decisions, build-vs-buy analysis, and a prioritised implementation plan. Engagements typically run 4–8 weeks for the initial assessment, with optional ongoing advisory.
Large consulting firms often deploy junior consultants, deliver slide decks, and move on. Xethos is founded by a hands-on engineer with over a decade of experience building production systems. We write code, review architectures, and stay engaged long enough to see our recommendations through. Our advice comes from building, not just advising.
Yes. We specialise in practical AI adoption and workflow automation for small and medium businesses. Rather than chasing trends, we identify the specific manual processes costing you time and money, then implement targeted automation - from intelligent document processing to CRM workflow automation to AI-assisted customer support - with clear ROI metrics.
Building an engineering team from scratch means defining the roles you need, designing interview processes that identify the right people, creating technical assessments, establishing team structure and engineering culture, and then hiring and onboarding your first engineers. We've done this multiple times across different industries and company stages, from first-hire startups to scaling teams from five to fifty.
