## **From Data Autonomy to Adaptive AI: Building Systems That Change How Decisions Get Made** **DOORS OPEN: 18:30** **TALKS START: 19:00** **NETWORKING: 20:00 - 21:30** ## **Our Speakers** **Marta Expósito Ventura, PhD, Head of Data, Stark Future** **Africa Perianez, Co-founder & CEO, Causal Foundry** ## **Marta Esposito - From ticket queues to data autonomy - engineering the shift** **Marta Esposito is Head of Data at Stark Future, an electric motorcycle company building high-performance, connected vehicles at the intersection of hardware, software, manufacturing and data.** **In her talk, Marta will explore what it takes to move a data function away from reactive ticket queues and towards a more autonomous operating model. As connected products generate increasingly rich streams of operational, product and user data, the role of data teams changes: from responding to requests, to enabling better decisions across the organisation.** **Her session will look at the engineering, organisational and cultural shift behind data autonomy: how teams structure data work, prioritise internal demand, build trust in data products and move closer to the real systems they support.** ## **Africa Perianez - Designing AI for imperfect conditions** **Africa Perianez is Co-founder and CEO of Causal Foundry, where she leads a team of engineers and AI scientists building reinforcement learning and personalisation technologies for real-world operational decision-making.** **Her work focuses on adaptive AI infrastructure that supports decisions across healthcare, logistics, behavioural nudging, demand forecasting, stockout prevention and resource allocation. Causal Foundry works with global partners including the Gates Foundation, Google.org, GAVI, Lilly and Johnson & Johnson, applying AI in environments where decisions are complex, resources are constrained and impact matters.** **In this talk, Africa will explore how AI systems move beyond prediction and dashboards into adaptive decision support. What does it take to build systems that can operate across changing contexts, local constraints and human behaviour? And how do you design AI that supports better decisions without pretending the real world is cleaner than it is?** ## **What’s In It For You?** **Some of the most interesting work in AI today is not just about building more powerful models. It is about turning data, machine learning and decision intelligence into systems that people and organisations can actually use.** **In this DeepTech Talks edition, Marta and Africa will explore two complementary sides of applied AI: how data teams become more autonomous inside complex organisations, and how adaptive AI systems support operational decisions in the real world.** **You’ll hear about:** * **How data teams move from reactive service models to autonomous data products** * **What it takes to build AI systems that support operational decision-making** * **How reinforcement learning and personalisation can be applied beyond consumer tech** * **The gap between dashboards, predictions and decisions that actually change outcomes** * **How technical teams work with messy real-world systems, constraints and stakeholders** **Expect a grounded conversation about AI that becomes s part of how organisations sense, decide and act.** ## **Who Should Come?** * **Data scientists, ML engineers and AI engineers** * **Data leaders, analytics leaders and engineering managers** * **Product leaders working with data-heavy or AI-enabled systems** * **Deep tech founders and technical operators** * **People working across healthtech, mobility, logistics, manufacturing or decision intelligence** * **Anyone curious about how applied AI becomes operational infrastructure** ## **Extras** **We’ll have food and drinks. 🍷🍕** **Come ready to meet engineers, founders, esearchers, data leaders and technology builders working on the next generation of applied AI systems.** **Spaces are limited, so grab your spot on Meetup while you can.** **Brought to you by DeepTech Recruitment & Cloudworks.** The organisers and venue reserve the right to refuse admission or entry and shall not be held liable for any incidents, losses or damages occurring during the event.

We will meet at La Querida, Passeig de Pujades 33, [https://goo.gl/maps/u5ZpycVXeZb7XyeE9](https://goo.gl/maps/u5ZpycVXeZb7XyeE9) You can leave your stuff there and we will begin running from outside the bar. A description of the route is below for your information. Before the run, we take a group photo and after we drink and/or eat at the bar (not mandatory). We will chat a bit before starting to run. The distance is about 10 kilometers (\~6 miles). However, there are plenty of opportunities to turn back before and sometimes people run a shorter distance. Each person runs at her/his own pace. Most of the time people are talking/chatting so it's honestly a casual run. Mini groups tend to form according to pace. Please note people run at their own risk and please if you have any medical condition make sure you let someone know and be sensible, run within your abilities. And don't forget to check our [facebook group](https://www.facebook.com/groups/319006355235925/) for news and activities! We kick off by running into the Ciutadella Park via the main gate. We then take a right to exit the park and immediately take a left to run alongside the round wall of the zoo (Passeig de Cicumvallacio). We then turn right at Carrer de Ramon Trias Fargas and head towards the beach. We then take a left turn and run along the beach heading northeast. Along the coast, we cross the Passeig Maritim de la Mar Bella for a quick stop at the water fountain and then turn back. The main change on the way back is that we turn right at the tram station along the other wall of the zoo (continuation of Carrer de Wellington) and once we reach the end of the wall, we are back to Passeig Pujades where we end our run.

New Meetup is here! Let's gooo!

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
