Vetted Fractional CTO Services

A fractional CTO is a senior technology executive who joins a company part-time, on an ongoing basis, to lead technology strategy, architecture, and engineering decisions. Instead of hiring a full-time executive, companies engage a fractional CTO for a defined number of hours per week, typically 10 to 25, for as long as the work requires it. Engaging a fractional CTO is a common step for founders who need executive-level judgment without the full-time commitment.

Fractional CTO rates through Tecla depend on scope, seniority, and whether the CTO leads engineering directly. There are no upfront fees, no fees to start the search, and no charges for interviews. The proposed fee based on scope is all-inclusive.

The scope of the work is similar, senior technology leadership. The difference is in hours, cost structure, and commitment. A full-time CTO works 40+ hours per week with a six-figure salary and equity. A fractional CTO works 10 to 25 hours per week on a monthly retainer, with no equity required and flexibility to scale up or down.

They are the same underlying engagement, delivered under different names. CTO as a Service is a framing borrowed from SaaS, more common with dev shops and companies used to buying tech functions as ongoing services. Fractional CTO is the more common framing in the startup ecosystem for the same fractional tech leadership model. Both describe senior technology leadership on demand, without a full-time hire.

The terms overlap significantly. Outsourced CTO usually implies a fully external, vendor-style relationship, more common in SMBs and non-tech businesses. Fractional CTO usually implies a leader who embeds part-time in the company. In practice, the market uses the terms interchangeably, and the engagement structure is often the same.

Common triggers include: needing senior technical judgment before a Series A raise, filling a leadership gap between full-time CTO hires, adding CTO-level oversight to an engineering team that is running without one, or supporting a founder without a technical background through a critical build phase.

Engagements typically run from three months to multiple years. Most start at three to six months and extend as the work continues. Companies often transition fractional engagements to full-time hires when the role grows beyond part-time scope, and we support that transition through executive search.

Yes. If the fractional CTO engagement does not work within the first 90 days, we replace the leader at no additional cost. The guarantee is standard across every engagement we run.

Most companies work with specialized fractional CTO firms rather than running an independent search. Tecla is one of the fractional CTO companies focused specifically on senior tech leadership, with a network of pre-vetted executives ready to match within days. An independent search typically takes weeks and lacks vetting rigor.

First candidates are typically presented within 3 to 5 business days of the briefing call. Most engagements are up and running within two weeks of the initial conversation.

Sometimes. In many engagements, the fractional CTO transitions to a full-time role once the company reaches the scale that justifies it. When that is not the right fit, Tecla runs the executive search for the permanent CTO alongside the fractional engagement.
