Fintech NerdCon

Fintech NerdCon is a deliberately practitioner-focused US fintech conference oriented around the engineering and technical side of financial services, staged at the San Diego Convention Center in San Diego, California. The event gathers software engineers, architects, technical product managers and engineering leaders for two days of sessions focused on how fintech systems are actually built, scaled and operated. It sits alongside Money20/20 USA, FinTech Meetup and FinovateFall as the calendar anchors for the US fintech operator community.

What happens at Fintech NerdCon

The programme combines technical deep-dive sessions on payment infrastructure, banking APIs, real-time payments engineering, fraud detection systems, ledger and accounting system design with broader sessions on engineering leadership, architecture decisions and the practical realities of operating fintech systems at scale. Workshops and code-along sessions feature alongside conventional talks. The event is deliberately scaled down from the major fintech conferences (Money20/20 USA at 14,000+ delegates, Fintech Meetup at similar scale) to support depth over breadth, with sessions long enough to cover engineering trade-offs rather than just high-level talking points. Side events — engineering-leader dinners, vendor technical demos, after-hours hospitality — extend the programme into focused practitioner-network time.

Who attends

The audience is overwhelmingly technical: software engineers and technical leads from US fintechs and banks, principal and staff engineers responsible for payment, ledger and banking systems, engineering managers and directors, technical product managers with engineering backgrounds, and senior architects designing fintech and banking systems. Attendance skews toward growth-stage and mature US fintech operators alongside engineering teams from US banks investing in modernisation. Vendor presence is meaningful but heavily concentrated in API platforms, infrastructure tools, engineering productivity tools and developer-facing fintech infrastructure rather than business-oriented sales-side vendors. The conference is not a fintech-deals event and is not a regulatory-affairs conference in the traditional sense — it is an engineering practitioners' forum for people who actually ship fintech code.

Dominant themes at Fintech NerdCon 2026

The engineering agenda emphasises the architectural choices and operational realities of US fintech systems: payment integration patterns across cards and account-to-account rails, the engineering implications of FedNow and RTP network adoption (idempotency, reconciliation, exception handling), ACH modernisation and Same Day ACH operational dynamics, ledger and accounting system design at scale, fraud detection architecture under tightening regulatory expectations, the practical mechanics of building open-banking APIs under the Consumer Financial Protection Bureau's section 1033 rulemaking, embedded finance API design, and the increasingly common application of stream processing, event sourcing and modern data architectures in financial services. The role of AI in engineering productivity and as a system capability itself receives substantial coverage — code-generation tooling, AI agents for incident response, LLM-based customer-service infrastructure.

Planning to attend

San Diego is well-connected by air across North America with direct flights from major hubs; San Diego International Airport (SAN) sits about 10 minutes from the convention centre. Hotel supply in the Gaslamp Quarter and downtown San Diego is plentiful and walkable to the convention centre. November timing puts the event in San Diego's pleasant late-autumn weather window. The technical audience and intermediate scale make this an unusually high-quality networking event for engineering leaders looking to compare notes with peers — most attendees report that informal conversations between sessions are the highest-value part of the conference. The conference language is English.
