Fractional Ecommerce CTO Chief Technology Officer Service

Ecommerce technology challenges rarely come from a single platform. They come from growth outpacing structure, where ecommerce, ERP, marketing, fulfilment and data platforms evolve quickly, but no one owns the overall technical direction.

The Fractional Ecommerce CTO Service from Cogent2 provides senior, part time technology leadership for ecommerce-led businesses. This role operates at an executive level, owning ecommerce technology strategy, architecture and decision making across all systems that support online trading and growth.

It is designed for ecommerce brands that have moved beyond simple platform builds and now need experienced leadership to guide scale, performance and long-term technical decisions, without committing to a full-time CTO.

Cogent2’s Fractional Ecommerce CTOs work inside the business, partnering closely with founders, COOs and ecommerce leaders. Alongside senior leadership, you gain access to a joined-up technical and integration team that can execute, refine and optimise what is set at a strategic level.

When to hire a Fractional Ecommerce CTO

This service is particularly well suited to ecommerce businesses that:

• Generate the majority of revenue online

• Operate across multiple platforms and vendors

• Are scaling traffic, order volume or international reach

• Lack clear ownership of ecommerce technology decisions

• Want senior technology leadership on a part time basis

Hiring a Fractional Ecommerce CTO brings clarity, confidence and accountability to ecommerce technology strategy.
