Chief technology officer
A chief technology officer (CTO) is the senior executive who owns a company’s technology strategy, engineering teams, and product platforms. The CTO turns business goals into shipped technology, choosing the stack, setting the roadmap, and making sure what the company builds matches what customers actually need.
Key takeaways
- A CTO owns technology strategy, engineering hiring, and product architecture at the executive level.
- The role pays a US median around USD 200,000 and sits on the C-suite alongside the CEO and CFO.
- CTOs differ from CIOs: the CTO faces the product and customer, the CIO faces internal IT operations.
- Many growth-stage firms hire a fractional or outsourced CTO before committing to a full-time hire.
Most companies didn’t have a CTO until software became core to revenue. Now the role sits on almost every venture-backed cap table and most mid-market boards.
How it works
A CTO sets the technical direction, picks the architecture, hires engineering leaders, and owns the build-versus-buy calls that shape product economics. They report to the CEO, partner with the chief information officer on infrastructure, and translate roadmaps for the board.
The day-to-day shifts with company stage. Early-stage CTOs code. Series-B CTOs hire managers and set hiring bars. Public-company CTOs run innovation labs, vendor relationships, and external partnerships including outsourced software development contracts.
Most CTOs spend roughly a third of their week on people decisions, a third on architecture and technical review, and a third on external work: customer escalations, board updates, analyst calls, and partner meetings. In firms running formal agile programs, the CTO is the tie-breaker when product and engineering disagree on scope or sequencing.
Four common CTO archetypes show up in practice:
| Archetype | Primary focus | Best fit |
|---|---|---|
| Infrastructure operator | Data, security, network reliability | Regulated industries, fintech |
| Strategic planner | Stack choices, roadmap, M&A tech diligence | Scaling SaaS, growth-stage |
| Customer-facing CTO | Pre-sales, customer engineering, field demos | Enterprise software, B2B |
| Visionary | R&D, emerging tech, corporate strategy | Mature firms, conglomerates |
According to the U.S. Bureau of Labor Statistics, computer and information systems managers — the umbrella the BLS uses for CTOs and CIOs — earned a median USD 169,510 in 2023, with the top decile clearing USD 239,000. Public-company CTOs in tech routinely earn far more once equity is counted.
Examples
Werner Vogels has been CTO of Amazon since 2005 and is the public face of AWS architecture decisions, including the company’s serverless and AI infrastructure push announced at re:Invent 2023. His role is the “visionary plus customer-facing” hybrid most large tech firms aspire to.
Bret Taylor served as CTO of Facebook (2009-2012), co-CEO of Salesforce (2021-2022), and now runs the AI startup Sierra — a useful reminder that the CTO seat often springboards into CEO roles. A 2024 Deloitte CTO survey found 41% of CTOs at Fortune 500 firms now sit on the executive committee, up from 28% in 2018.
In outsourcing-led setups, Manila-based BPO Acquire BPO publicly named a chief technology officer in 2022 to run its automation and cloud roadmap across 16,000 staff. That signals the role has moved well beyond Silicon Valley unicorns into operational service firms. Fractional CTO arrangements, where a senior engineer splits time across three or four startups, became a standard offering at firms like Toptal and CTO.ai through 2023-2024.
A useful counter-example sits in non-tech industries. When US retailer Walmart promoted Suresh Kumar to global CTO in 2019, the brief was to rebuild Walmart.com’s stack and absorb the Jet.com platform. By 2024 the company reported USD 100 billion in e-commerce sales, with most of the engineering work routed through a global capability center in Bengaluru. That model, where the CTO sits in headquarters but the bulk of engineering runs from an offshore development centre, is now common in retail, banking, and insurance.

FAQ
What does a CTO actually do day to day?
A CTO splits time between strategy (roadmaps, board updates, vendor calls), people (hiring senior engineers, settling architecture debates), and selective hands-on work on the highest-stakes technical decisions.
CTO vs CIO: what’s the difference?
The CTO is product-facing and external: they decide what the company builds and ships to customers. The CIO is operations-facing and internal: they run the IT systems employees use, from email to ERP. Some smaller firms combine both roles into one seat.
How much does a CTO earn?
In the US, the BLS reported a median around USD 169,510 in 2023 for the broader manager category, with named public-company CTOs often clearing USD 1 million once equity vests. Startup CTOs typically take lower cash and higher equity.
Can a CTO be outsourced or fractional?
Yes. Fractional CTOs work 1-3 days a week across multiple companies and are common for seed-stage startups, family businesses moving online, and mid-market firms running a single transformation program. Rates run USD 200-500 an hour.
Does a CTO need a computer-science degree?
Not formally. Most CTOs hold a CS, engineering, or math degree, but a 2023 Harvard Business Review piece noted a growing share of CTOs come from product or operations paths, especially in non-tech industries adopting software.
