From the room

The ideas worth taking with you.

The strongest ideas, disagreements and practical lessons from data leaders doing the work.

01

LLMs: risk & workflows

Brenn Hill · Engineering & Data Science / ML Leader at Delivery Hero

A grounded look at production use cases, trust, privacy, reliability and the foundations required to turn an impressive demo into a system people can depend on.

Productivity is the clearest value today

Copilots and agents help with scaffolding, refactors, tests, debugging and repetitive delivery work. Strong use cases have constraints and measurable outcomes rather than vague ambitions.

Build workflows, not chatbots

The patterns that survive production have defined inputs and outputs, explicit permissions, deterministic checks, approval gates and sensible fallbacks. Repeatability beats occasional brilliance.

The boring foundations are the multiplier

Shared definitions, documentation, metric alignment, data contracts and access rules determine the quality of model output. LLMs amplify strong foundations — and scale confusion when they are weak.

Mitigate risk through design

False confidence is often more dangerous than an obvious failure. High-stakes workflows need human review, references, safe-failure behaviour, privacy policy and tightly constrained actions.

Make learning reusable

Teams are pairing product and architecture roles, creating prompt and workflow libraries, introducing lightweight AI reviews and designing unit economics into workflows from day one.

Is prompt-based analytics worth solving?

Marc Roulet · VP Data & Analytics at sevdesk

An honest debate about natural-language self-service: where it can help, where confident but incorrect answers can damage trust, and why shiny technology still needs a genuine business case.

Self-service only works when users can frame good questions

If end users cannot ask the right questions or interpret the answers, natural-language analytics risks creating more confusion than clarity.

Confidently wrong is the dangerous failure mode

The biggest risk is not an empty answer but a convincing, incorrect one that becomes the basis for a business decision.

Use it as a co-pilot, not a pilot

Prompt-based analytics is most useful for quick exploration, brainstorming and helping people get started; critical interpretation and validation remain human work.

Trust is non-negotiable

Data teams spend years building credibility and can lose it quickly. Safeguards, validation and clear limitations must be part of the product, not an afterthought.

At-scale reliability remains hard

Leaders had experimented with several options, but none consistently delivered results they would confidently roll out at scale. Building your own is unrealistic for most organisations.

Training helps — but is difficult to scale

Structured training can teach responsible use and interpretation, though providing and enforcing it across a large organisation takes real effort.

Data teams become safe-self-service enablers

The role shifts toward boundaries, adoption guidance, data quality and trust. Human expertise and AI assistance work best together.

Business need comes before democratisation

Wider access is not inherently valuable if the answers are false or useless. Progress depends on cautious adoption and relentless focus on a real problem.

What does “good” look like in analytics?

Chase Richards · Head of Analytics at Zalando

A roundtable on moving beyond dashboard output: clearer standards, stronger career paths and analytics that earns its seat in business strategy.

Excellence means business impact

The best teams connect initiatives to revenue, retention, efficiency and innovation, turning analytics into a strategic growth lever rather than a reporting function.

Insights matter more than outputs

Dashboards do not change a business by themselves. Strong teams explain the why behind the numbers and translate it into recommendations leaders can act on.

GenAI raises the value of multidisciplinary analysts

As rote pulls and dashboard creation automate, technical expertise, business judgement, storytelling, experimentation and metric curation matter even more.

Career frameworks make quality scalable

Transparent expectations and levelling give people a path to build skills, earn promotion and take on leadership — helping good analysts stay and grow.

Measure decisions and outcomes

Success is better measured through decisions influenced, experiments launched and outcomes achieved than through the volume of dashboards delivered.

Embed analytics in strategy

Analytics should shape the business playbook at eye level with stakeholders, aligned directly with growth, retention and operational priorities.

Data leadership is influence

The strongest leaders combine technical depth, commercial awareness and storytelling to inspire action and make data part of competitive advantage.

Measuring marketing performance

Andre Wagner · Head of Data Analytics at Taxfix

A Data Leader Roundtable on attribution, brand measurement and the shared definitions Data and Marketing need in order to build solutions people can trust.

Acquisition surveys are overused for attribution

Customers can be asked where they came from, but an acquisition survey is a weak answer to every attribution question. Some channels, including radio beyond voucher use, remain difficult to measure conclusively.

Brand measurement remains unresolved

Leaders agreed that brand and brand equity matter, while also recognising that a comprehensive, dependable way to measure them is still elusive.

Clear naming improves data reliability

Marketing-led naming conventions for campaigns and vouchers make analysis more accurate and give teams a more dependable basis for comparison.

Align on definitions before building

Agreeing expectations and how numbers will be interpreted at the start reduces the back-and-forth that otherwise arrives after a solution has been delivered.

Choosing the right data tools

Valentin Umbach · Analytics Lead at komoot

A practical comparison of in-house, purchased and open-source data tools — including the less visible risks around knowledge, maturity, lock-in and total cost.

Protect against knowledge walking out of the door

In-house tools can fit internal knowledge closely, but they create continuity risk when the people who built them leave. Purchased tools can reduce that dependency.

Open source can preserve flexibility

Open-source tools can reduce cost and help prevent vendor lock-in, giving teams more room to evolve their stack over time.

Research before committing

A crowded tooling landscape makes deliberate evaluation essential. Teams need to compare capabilities against the problem they actually need to solve.

Let new tools mature

Exciting technology is not always ready for dependable use. Waiting for greater maturity can avoid avoidable bugs and operational problems.

Balance capability with total cost

The most advanced option is not automatically the best. Budget, operating cost and long-term ownership all belong in the decision.

The ROI of data

Anna Smolina · Data leader and roundtable host

A discussion centred on one of the hardest leadership questions: how to make the value of data work visible and stop the function being treated only as a cost centre.

Start with the decision or outcome

The value story becomes clearer when data work begins with the business decision, behaviour or result it is intended to improve.

Make contribution visible

Leaders need a consistent way to show where analytics changed a decision, reduced risk, improved efficiency or created commercial value.

Prioritisation is part of the ROI story

Choosing high-value problems — and being explicit about what will not be done — helps the team concentrate effort where it can matter most.

Translate technical work into business language

Stakeholders respond to speed, quality, revenue, cost and risk more readily than to outputs, pipelines or model complexity on their own.

The modern analytics stack

Valentin Umbach · Head of Analytics at LOVOO

A three-part roundtable on the role of a metrics layer, the limits of self-service and the enduring challenge of measuring the value created by analytics.

A metrics layer can create shared meaning

The discussion examined whether a common metrics layer is the missing connection between modern data infrastructure and consistent business definitions.

Self-service is more than access

Tools alone cannot supply context, creativity or communication. Those human elements shape whether self-service produces understanding or simply more output.

Analytics value needs deliberate measurement

Teams need to look beyond delivery volume and ask how analytics work changes decisions, behaviour and measurable business outcomes.

Data democratisation & the right tech stack

Sowmia Naraynan · Head of Analytics Platform at TIER Mobility

A connected conversation about widening useful access to data while choosing a technology stack that supports the organisation rather than dictating how it must work.

Democratisation needs dependable foundations

Broader access is most valuable when people can trust definitions, understand context and know where responsibility for quality sits.

Choose a stack for the organisation you have

The right technology depends on team capability, operating model, use cases and constraints — not simply on which tools are receiving the most attention.

Access and architecture are linked

How the stack is designed affects who can work with data, how independently they can act and where specialist support is still required.

Enablement remains a human responsibility

Documentation, guidance and communication determine whether new access becomes genuine capability across the business.

Data teams & project size

Divya Bokaria · Head of Data & Analytics at Zattoo

A Data Leader conversation about how the scale and nature of a project influence team shape, leadership attention and the way work should be organised.

Match the team to the problem

Project size is only one dimension; uncertainty, dependencies and the mix of skills required also shape the team that can deliver well.

Keep ownership clear as work grows

Larger initiatives create more interfaces. Explicit decision rights and ownership help prevent coordination from overwhelming delivery.

Ways of working should evolve with scale

The practices that suit a small exploratory project may not be enough when more teams, stakeholders and operational risks become involved.

Cloud, DevOps & ownership in data teams

Peter Greškovič · Data leader and roundtable host

A wide-ranging leadership discussion connecting infrastructure choices with DevOps practice and the question of who owns data products once they are in use.

Cloud versus self-hosted is a trade-off

The right choice depends on control, capability, security, cost and the operational responsibility a team is prepared to carry.

Bring DevOps thinking into data

Reliable delivery requires repeatable deployment, observability and shared responsibility for systems after they move into production.

Ownership must survive hand-offs

Clear accountability across data producers, platform teams and consumers helps prevent quality and operational issues from falling between teams.

Architecture and operating model belong together

Infrastructure decisions work best when they reflect who will run the platform, support users and make changes over its lifetime.
