Welcome to Emerging Technology & Finance

  • This is a flipped-classroom Bachelor course: every regular lecture (odd weeks) is followed by a flipped session (even weeks) where all groups present on the same topic. There is no exam to register for — sign up on the course Moodle page by 15 October 2026 so you receive announcements and the token-allocation quiz links.
  • Form a group of 4 by the end of Week 1 (Moodle sign-up sheet). Stragglers will be allocated by the lecturers.
  • Grading is 100% cumulative across the 6 flipped sessions: each session = 50% peer-allocated tokens + 50% lecturer evaluation. Each group gets 20 fresh tokens every flipped week to allocate to other groups via a Moodle quiz within 5 minutes of the session ending.
  • Submission per session: upload your slide PDF to Moodle before each flipped session starts. Ask questions during or right after each session — that is the preferred channel.
  • Admin / studies / exam-eligibility questions go to the registrar’s office (Studiensekretariat) at studiensekretariat@uni-ulm.de.
  • Course-content questions outside class: email oliver.padmaperuma@uni-ulm.de, CC andre.guettler@uni-ulm.de.
  • We also recommend the student advisory service.

Course Objective

Scope

We will:

  • Survey six emerging-technology modules at the cutting edge of finance: agentic AI · blockchain & DeFi · fintech business models · RegTech & cybersecurity · CBDCs
  • Pair every regular lecture with a flipped session in which every group presents their angle on the topic
  • Train critical evaluation, presentation, and peer-judgment skills via a transparent token-based peer-grading mechanic
  • Place the technologies in a real-world business and regulatory context (PSD2/3, MiCA, EU AI Act, post-quantum standards)

We will NOT:

  • Build production-grade fintech systems or trade live capital
  • Cover deep technical implementations (we treat code as supplement, not core)
  • Run a separate written exam or final-pitch competition — the cumulative flipped-session grade is the entire grade

Approach

Flipped-classroom alternation (12 weeks)

  • Odd weeks (W1, W3, W5, W7, W9, W11): regular lecture introducing the topic
  • Even weeks (W2, W4, W6, W8, W10, W12): flipped session — all groups present and allocate tokens
  • Groups of 4, formed by end of Week 1

Token mechanic (the grading vehicle)

  • 20 tokens per group per flipped session
  • Each group allocates them to other groups, weighing insight · originality · clarity · critical depth
  • Cumulative across 6 sessions = 50% of final grade · lecturer evaluation = 50%

  • 8.3 Session agenda
  • 8.5 Token allocation
  • 8.6 Lecturer reflection
  • 8.7 Wrap-up & next steps
  • What we covered last week
  • Open questions to dig into today

What we covered last week

  • Neobanks — N26, Revolut, Monzo, Chime. Customer-acquisition cost vs lifetime value; the long road to profitability (Vives 2017).
  • Embedded finance & BaaS — Stripe, Marqeta, Solaris, Adyen. Banking infrastructure as an API.
  • BNPL — Klarna, Affirm, Block Afterpay. Subprime credit in fintech clothing, or genuine innovation?
  • Open Banking & PSD2 — what data-sharing mandates actually delivered, who built on top (European Parliament and Council 2015).
  • Big Tech in finance — Apple Card, Google Pay, Amazon Lending — defensive moats or offensive land-grabs? (Frost et al. 2019).
  • Fintech lending — what the literature finds about FinTech vs bank credit supply (Berg, Fuster, and Puri 2022).

Open questions to dig into today

  • Neobanks: profitable yet — or perpetually one funding round away?
  • BNPL: real consumer innovation, or repackaged subprime lending?
  • PSD2 was meant to spark Open Banking competition. Has it actually?
  • Why has no European Big-Tech-style super-app emerged (vs. Alipay, WeChat, Grab)?

What groups present today

Presentation brief

6 min + 2 min Q&A. Each presentation must include:

  1. One specific company / product / regulation.
  2. Unit economics — CAC, LTV, take-rate, NIM, default rate — whichever applies. Bring numbers.
  3. Critical view — what could break this model? Who is already trying to break it?
  4. 1–2 discussion prompts.

8.4 Group presentations

Group 1 — Neobank unit economics

  • Pick one. Bring: revenue per user, CAC, retention curve, the latest reported operating profit (or loss).
  • The strongest version compares the neobank’s metric directly to an incumbent bank’s.

Group 2 — BNPL provider

  • Pick one. Bring: take-rate from merchants, default rate among users, the regulatory action(s) since 2023.
  • The strongest version answers “is this profitable on a fully-loaded credit-loss basis?”

Group 3 — Embedded finance / BaaS

  • Pick one. Bring: how it makes money (transaction fees, licensing, float), who the customers are (other fintechs, retailers, gig platforms), and the regulatory pushback (e.g. BaFin & Solaris).
  • The strongest version explains why a non-finance company would buy financial primitives as APIs.

Group 4 — Big Tech in finance

  • Pick one. Bring: what financial service it provides, who the underlying bank is, and the strategic role (defensive moat protecting the core product vs offensive land-grab).
  • The strongest version answers “why hasn’t this disrupted incumbents yet?”

Group 5 — Super-app outside Europe

  • Pick one. Bring: financial-services penetration, regulatory environment, and the cultural / infrastructure preconditions that made it possible.
  • The strongest version names what would have to change in Europe for a similar super-app to emerge.

Group 6 — Open Banking outcomes

  • Bring: API call volumes (UK CMA data, EU comparable), names of consequential third-party providers (Plaid, TrueLayer, Tink), and the honest answer to “did PSD2 actually create competition?”
  • The strongest version separates regulatory intent from measured outcome.

Standout insights & common gaps

  • Standouts (live-fill): groups that combined a real unit-economics number with a sharp regulatory observation.
  • Common gaps (live-fill): typically — (a) headline user counts without revenue per user; (b) press-release valuations as evidence; (c) assumed regulators are static when they are decisively reshaping BNPL and BaaS.

Concepts to revisit next regular lecture

  • Every business model we discussed today operates inside a compliance perimeter — KYC, AML, data protection, operational resilience. Lecture 9 zooms into that perimeter.
  • The interesting governance question that emerged tonight: as fintech volumes grow, how much of the regulatory burden can / should be automated?
