Quote: The CTO as the 'sh*t umbrella'

The concept of the CTO as a "shit umbrella" was popularized by former Twitter Engineering Director David Loftesness, who described it as a core part of a servant leadership model. This approach emphasizes that a leader's primary role is to shield their team from distractions like corporate politics, unclear requirements, and excessive meetings, thereby creating a stable environment for focused, high-quality work. Moving into a CTO role requires a fundamental shift from pure technology management to becoming a strategic business partner. This involves aligning the technology roadmap with fundraising goals, participating in investor pitches to articulate technical value, and building strategic partnerships to accelerate growth. The founder-CTO relationship is pivotal, built on mutual trust in each other's domain expertise and a clear division of responsibilities to avoid friction. A critical, and often external-facing, CTO function during growth is leading technical due diligence for M&A or major partnerships. This involves a methodical assessment of a target's architecture, codebase, security posture, and engineering processes to identify risks and scalability limits. The process is not just an audit but a collaborative investigation to ensure the technology can support future business objectives. The programmatic advertising landscape is shifting focus toward efficiency and sustainability. Key trends for 2026 include the consolidation of retail media networks, the growing dominance of Connected TV (CTV) in brand budgets, and the use of AI for smarter targeting and optimization in a post-cookie world. Supply Path Optimization (SPO) is now a primary focus for advertisers, rewarding publishers who offer direct, transparent inventory. Measurement remains a core challenge in adtech, as fragmented customer journeys and signal loss from privacy changes make traditional attribution models less reliable. Marketers are shifting towards first-party data, incrementality testing, and Media Mix Modeling (MMM) to better understand ROI. This creates an opportunity for infrastructure leaders to build products that provide clearer, more trusted analytics. Enterprise software is being reshaped by AI agents and agentic workflows, which are autonomous systems that can plan, act, and adapt to complete complex, multi-step tasks. Companies like ServiceNow are using them to automate IT and HR processes, reducing manual workloads by up to 60%, while other applications are emerging in finance and customer service to accelerate business processes by 30% to 50%. The UK's startup ecosystem has seen a strong start to 2026, with companies raising a collective $4.26B in the first two months of the year. London-based SaaS companies accounted for $5.4M of that in January alone. "Soonicorns" (companies valued between $250M and $1B) to watch include London-based MatNex, which uses AI for advanced materials discovery, and Shop Circle, which has raised $245M for its e-commerce software tools. Formula 1's governing body, the FIA, has approved changes to the 2026 engine regulations to close a loophole allegedly exploited by Mercedes around compression ratios. Elsewhere in London, TfL tube fares are set to increase today, March 1st, with a Zone 1 peak single fare rising to £3.10. Meanwhile, international flights from London on Air India have been cancelled due to airspace closures over the Middle East.
