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%

8.2 Recap: Fintech Business Models

- 8.5 Token allocation
- 8.6 Lecturer reflection
- 8.7 Wrap-up & next steps
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).
Notes
The big lesson from Lecture 7 is that most fintech business models are still unproven at scale. Neobanks took a decade to reach the operating-profit line; BNPL is currently being repriced by regulators; embedded finance survives on take-rates that look ten years away from being defensible. Tonight, dig past the press releases into actual unit economics.
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)?
Notes
Bring numbers tonight. “Revolut has 50M users” is not a business model. “Revolut earns €5 per user per quarter from interchange + premium subscriptions, with a CAC of €20 and a 70% retention curve” is.

What groups present today
6 min + 2 min Q&A. Each presentation must include:
- One specific company / product / regulation.
- Unit economics — CAC, LTV, take-rate, NIM, default rate — whichever applies. Bring numbers.
- Critical view — what could break this model? Who is already trying to break it?
- 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.
Notes
Live-fill slide.
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?”
Notes
Live-fill slide.
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.
Notes
Live-fill slide.
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?”
Notes
Live-fill slide.
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.
Notes
Live-fill slide.
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.
Notes
Live-fill slide.

How tokens work
- 20 fresh tokens per group per session.
- Other groups only — no self-allocation. Total = 20.
- Moodle quiz opens for 5 minutes after the last presentation.
Notes
Standard rules — week 8 means you’ve done this three times now.
Allocation rubric
- Insight — taught you something new?
- Originality — fresh angle?
- Clarity — followable?
- Critical depth — honest appraisal?
Notes
Tonight reward groups that brought real numbers — CAC, LTV, take-rate. Vendor narratives are everywhere; honest unit economics are not.
Tonight’s leaderboard
| Group | Tokens this week | Cumulative |
|---|---|---|
| Group 1 | — | — |
| Group 2 | — | — |
| Group 3 | — | — |
| Group 4 | — | — |
| Group 5 | — | — |
| Group 6 | — | — |
- We’re now past the halfway mark — 4 sessions remain. Final standings start to shape from here.

- 8.7 Wrap-up & next steps
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.
Notes
The “valuation as evidence” failure is the most common: a fintech being worth $X in its last funding round is not evidence the business model works — it’s evidence the funding-round market believed it would, possibly years ago. Cross-check with reported operating profit.
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?
Notes
The pivot to Lecture 9 is natural: the same companies that built innovative business models now need to industrialise compliance. RegTech is where that industrialisation happens.
