iOTA Financial Solutions

Inspiration

Our inspiration came straight from the Toyota Financial Services challenge statement and a collective fear we observed: buying a car financing is intimidating. Too many people, especially young or first-time car buyers, fear the confusing terminology, hidden fees, and long commitments of loans and leases. We aimed to make this fearful experience simple and transparent. We sought to build a "financial co-pilot" that not only helps individuals find a car, but also educates them and builds their financial confidence, creating an affinity of trust with the Toyota brand.

What it does

iOTA Financial Solutions is a smart, user-centric web site that guides customers through the entire vehicle finance and lease process. It starts by asking some lifestyle and financial questions of the user. Based on that, our site: -recommends suitable Toyotas within their budget -educates them by defining tough financial terminologies -simulates payments -builds an exclusive Toyota community -streamlines the sale with online scheduling tools -assists owners with end-of-lease tips ahead of time, return car checklists, and open "wear and tear" policies. -provides value through an incentive program that rewards gas and rental car use, also serving as a new revenue source for Toyota.

How we built it

We built Iota using a modern React + TypeScript stack with Vite for lightning-fast development. The frontend leverages Tailwind CSS and Radix UI for a polished, accessible interface, with Framer Motion adding smooth animations throughout the user experience.

The backend is a Node.js Express server that integrates three powerful APIs:

Google Gemini 2.5 Flash-Lite for intelligent chatbot conversations ElevenLabs for natural text-to-speech voice responses Supabase for secure user authentication For the interactive Texas map, we integrated Leaflet with React-Leaflet and OpenStreetMap tiles to visualize real-time vehicle inventory across 8 dealership locations.

The AI-powered vehicle recommendation system uses a custom 100-point scoring algorithm that analyzes user preferences from our 5-step questionnaire, matching them with the perfect vehicle based on category, powertrain, budget, fuel efficiency, and predicted resale value.

Our financing calculator dynamically compares lease vs. finance options with real-time calculations, including insurance bundling and AI-powered resale value predictions through our Express API endpoints.

The entire development workflow ran on two servers (Vite dev server on port 3000, Express API on port 3001) with environment variable management through dotenv for secure API key handling.

Challenges we ran into

One biggest challenge was we didn't have APIs for a lot of necessary data so we had to use hard coded data at various places. Another one was that the prices of cars keep changing daily so there might not be financial accuracy if we use the hard coded data.

Accomplishments that we're proud of

We are most proud of creating a solution that focuses on the entire customer lifecycle, not just the initial sale. We included features like the end-of-lease support and the clear "wear and tear" policy to enhance the long-term trust and reduce customer anxiety. We also introduced a new incentive program. It’s a win-win-win: the customer gets tangible rewards (like gas), Toyota gains a new revenue stream from partners, and it increases customer engagement with the app long after they've purchased the car.

What we learned

We learned that simplifying finance has more to do than just building a calculator, but rather with building trust through transparency and education. We learnt how important it for a customer to feel comfortable on our website, which is why we made our website in a way that it makes the customer feel seen.

What's next for iOTA Financial Solutions

Our next step is to move from prototype to production by integrating directly with Toyota Financial Services' live credit application APIs and Toyota's real time dealership inventory. Launch the incentive program. We would begin formal partnership discussions with gas station chains and rental car companies to roll out the rewards program.
