Fractional CTO Sydney

Marshall Tech provides fractional CTO services in Sydney for growing Australian businesses that need senior technical leadership without hiring a full-time CTO. We guide architecture, vendor selection, roadmap planning, and delivery, then work alongside your team to turn the right technical decisions into shipped outcomes.

Best for

• Businesses doing $2M–50M revenue with 5–50 staff and no senior technical leader
• Founders evaluating build-vs-buy or platform migration decisions

Full details

Workflows & Automation

Marshall Tech builds custom workflows, APIs, and automation for Australian businesses with manual handoffs, broken connectors, or duplicated data. We map the process, design the integration layer, and ship monitored automation that reduces admin load, improves reliability, and removes vendor lock-in from critical operations.

Best for

• Businesses running multiple systems with manual data transfer between them
• Operations teams spending >10 hours/week on repetitive reporting or data entry

AI Consultant Sydney

Marshall Tech works as an AI consultant in Sydney for small and growing businesses that want practical AI tied to operations. We assess readiness, select the right use case, build the workflow, and add guardrails so AI systems are reliable, measurable, and usable in production.

Best for

• Businesses wanting to automate content production at scale with quality controls
• Operations teams drowning in manual data analysis and reporting

Full details

Custom Software & App Development

Marshall Tech builds production-grade custom software, web applications, and API-first platforms for businesses that need more than a brochure site or template tool. We design the backend, frontend, and infrastructure around your workflow so the product can launch quickly and scale without a rewrite.

Best for

• Businesses needing a web application or internal tool built in weeks, not months
• Startups validating a product concept before committing to a full engineering team

Full details

Tech Stack Optimisation

Marshall Tech audits messy tech stacks, broken integrations, and SaaS sprawl for Australian businesses that need cleaner systems and lower overhead. We map the tools, identify what to keep or cut, and fix the data flow so operators can trust the platform again.

Best for

• Businesses paying for 30+ SaaS tools with unclear ROI on half of them
• Companies with broken integrations, dirty data, or workflows held together with manual processes

Frequently Asked Questions

If you're unsure, start with a 2-week diagnostic. We'll audit your stack, map your processes, and recommend the highest-leverage service based on your specific situation. Most clients start with either a platform rescue, a workflow automation project, or a fractional CTO engagement.

Yes, and most clients do. A common pattern is fractional CTO plus workflow automation: strategic direction paired with immediate operational wins. Pricing adjusts for combined engagements.

Most engagements begin within 1–2 weeks of the initial discovery call. The 2-week diagnostic sprint is designed to deliver immediate value while we scope longer-term work.

Optimisation and automation projects: A$5k–$20k. AI implementations: A$10k–$50k. Full platform builds: A$40k–$100k. All projects start with a fixed-price scope sprint so there are no surprises.
