Career of Jakob Zebedee Leaf
Sales Intelligence Executive at AB InBev
Jakob currently works as a Sales Intelligence Executive at AB InBev, a major global brewing and beverage company. He began this full-time role in January 2025 and is based on-site in London.
In this position, he focuses on the accuracy, reliability and accessibility of sales data. His responsibilities include managing monthly data collection from account managers, overseeing quality control checks and carrying out root cause analysis when dashboard data errors occur.
A key part of his work involves designing and automating Python-based workflows to improve efficiency. He also acts as a link between technical teams and commercial teams, helping both sides understand data systems and use information more effectively.
Key Responsibilities at AB InBev
His work at AB InBev includes improving data ingestion formats, refining data cleaning standards and increasing backend data visibility. These improvements support faster and better-informed decision-making across commercial teams.
He has also led cross-functional workshops to identify process pain points and implement practical reforms. This shows that his role is not only technical, but also highly collaborative. He works with stakeholders to make data processes clearer, more scalable and more reliable.
Data and Analytics Experience
Albany Beck: Data and Analytics Pioneer Consultant
Before joining AB InBev, Jakob worked as a Data and Analytics Pioneer Consultant at Albany Beck from September 2024 to December 2024. This was a full-time role in the City of London.
Through Albany Beck’s Pioneer programme, he gained training in data analytics, Python, cloud computing, machine learning and digital transformation. The programme was designed to build both technical expertise and real-world problem-solving skills.
This experience strengthened Jakob’s ability to help organisations deal with complex data challenges. It also supported his transition into more advanced commercial and technical roles.
Outlier: AI Trainer
From June 2024 to September 2024, Jakob worked part-time and remotely as an AI Trainer with Outlier. His role involved training a large language model in mathematics, designing prompts and correcting outputs to improve answer quality.
This experience fits naturally with his mathematics background. It also shows involvement in the growing field of artificial intelligence, where mathematical understanding, clear communication and careful evaluation are essential.
Consultancy and Early Professional Roles
Artefact: Data Consultant
Jakob worked as a Data Consultant at Artefact from October 2022 to June 2023. During this period, he worked in a project team that created and maintained custom dashboards for an international automotive manufacturer.
His role involved reporting, analysis and client communication. He also helped lead an international development team while liaising with the client to refine project scope. This gave him experience across the full data journey, from source data to warehouse, platform backend and front-end dashboards.
He also built technical understanding in SQL, particularly while checking work completed by DevOps teams. Rather than focusing only on individual data queries, he developed a wider understanding of pipelines, errors and delegation of fixes.
Working within an agile framework gave him experience in setting realistic deadlines, reprioritising tasks and ensuring timely delivery of agreed items.
The Clifton Club: Steward
While studying for his master’s degree, Jakob worked part-time as a Steward at The Clifton Club in Bristol from September 2021 to June 2022.
This hospitality role helped develop practical people skills. Working in hospitality often requires calmness, teamwork, organisation and strong communication. These qualities can be highly useful in later consultancy and stakeholder-facing roles.
180 Degrees Consulting Bristol
From June 2021 to August 2021, Jakob completed a Consultant Internship with 180 Degrees Consulting Bristol. He worked with the charity WECIL to improve its member communication framework.
The team explored solutions for a busy phone line, including an online FAQ page, a peer-to-peer support chatroom and an AI chatbot-style solution. This early consulting experience showed an interest in using digital tools to solve real organisational problems.
