Building FinTech Applications on Bubble.io: A Practical Guide
Dividend Finance processed $1B+ in loans on Bubble. The platform works for FinTech — with clear boundaries. Six FinTech use cases that work well, what Bubble cannot do, and the pattern that makes FinTech on Bubble viable: Bubble as the operational layer on top of regulated infrastructure.
What Financial Applications Can Be Built on Bubble
Bubble.io has a documented track record in FinTech: Dividend Finance built a $1B+ loan origination portal on Bubble. Multiple insurance brokers, investment platforms, and financial services firms use Bubble for their operational infrastructure. The platform’s SOC 2 Type II certification, correct implementation of Stripe’s financial APIs, and enterprise security features make it viable for many financial use cases — with important scope boundaries.
Where Bubble Fits
Loan Origination Portals
Broker-facing and borrower-facing portals for collecting application data, uploading supporting documents, tracking application status, and coordinating with underwriters. This is Dividend Finance’s exact use case. Bubble handles the workflow orchestration; the actual loan processing happens in banking systems.
Insurance Broker Platforms
Policy management, renewal tracking, claims management, and client CRM for insurance brokers. The actual insurance underwriting happens with regulated carriers; Bubble manages the broker’s operational workflow and client relationships.
Investment Portfolio Trackers
Displaying portfolio holdings, performance charts, allocation breakdowns, and transaction history for investment clients. The actual trading and custody happens elsewhere; Bubble provides the reporting and client portal interface.
Financial Advisor Client Portals
Secure document sharing, financial plan access, meeting scheduling, and performance reporting for wealth management clients. Regulatory requirements for advice delivery are handled by the advisor; Bubble handles the operational relationship management.
Expense Management Tools
Employee expense submission, approval workflows, receipt upload, and reimbursement tracking for SMBs. Not payment processing; operational workflow management. A category where off-the-shelf tools often do not fit specific company workflows.
FinTech Startup MVPs
Validating a FinTech business model before investing in banking partnerships and regulatory approvals. A Bubble MVP demonstrates the user experience and workflow, allows product-market fit testing, and supports fundraising before the full regulated infrastructure is built.
The Honest Boundaries
| Capability | Can Bubble Do It? | What To Use Instead |
|---|---|---|
| Process bank payments directly | ✗ | Stripe (card payments) or banking API partners (Plaid, TrueLayer, Volt) connected via API Connector |
| Provide actual banking services | ✗ | Licensed banking partner; Bubble provides the front-end workflow only |
| Issue securities or investment products | ✗ | Regulated broker-dealer; Bubble provides operational tooling around it |
| Store card data (PCI DSS Level 1) | ✗ | Never store card data in Bubble; Stripe handles card storage |
| Sub-50ms trade execution | ✗ | Custom low-latency infrastructure; Bubble not designed for this |
| Act as a regulated financial entity | ✗ | Requires financial licensing; Bubble is a tool, not a regulated entity |
