Pulse — The Borderless Wealth App for Immigrants

Inspiration

The inspiration for Pulse stems from a family of 43 in Vietnam. My parents were the only ones from their families who moved to America to work and provide for our massive extended family. Growing up, I saw the "cost" of the American dream: my parents would spend thousands in fees and hours driving to locations like Walmart just to send money for birthdays, holidays, funerals, and traditions.

The current remittance system is a tax on love and obligation. We built Pulse to eliminate the physical and financial hurdles of supporting a family across borders, turning a chore into a seamless experience.

What It Does

Pulse is a multimodal financial ecosystem that transforms how immigrants manage their global footprint:

  • Instant Remittances — Bypasses physical kiosks. Users send money from a US debit card to an international card in under 60 seconds.
  • AI Budget Guard — Driven by Gemini 3.0, it ensures users never "over-send" and compromise their own survival.
  • Opportunity Engine — Identifies micro-investment opportunities for the money saved on fees.
  • Credit Builder — Validates "hidden" financial reliability, reporting remittance consistency to credit bureaus.
  • Lingo-Live — A multimodal voice assistant providing real-time financial translation for non-native English speakers.

How We Built It

We engineered Pulse to be "2026-ready" using a decentralized and agentic stack:

  • AI Core — Gemini 3.0 API utilizing the thinking_level: "high" parameter for financial reasoning.
  • Blockchain Rails — Circle API for USDC tunneling on the Solana network to minimize gas fees.
  • Frontend — React Native (Expo) with a voice-first UI for accessibility.
  • Payment Intake — Stripe and Apple Pay integration for one-tap funding.
  • Compliance — Automated KYC via Gemini 3 Flash (Vision) for instant ID verification.

Challenges We Ran Into

The primary challenge was balancing immediate family need with individual financial safety. We had to create a mathematical model for "Safe-to-Send" limits.

If $I$ represents monthly income, $E_f$ fixed expenses, and $\beta$ the safety buffer $(0.20)$, the maximum safe remittance $R_{\max}$ is calculated as:

$$R_{\max} = (I - E_f) \cdot (1 - \beta)$$

We also struggled with Agentic Liability. Ensuring that a Gemini-powered suggestion for an investment or a budget adjustment was safe and compliant with the 2026 GENIUS Act required building a "Truth-Checking" layer that validates AI responses against real-time bank balances.

Accomplishments That We're Proud Of

  • Fee Disruption — We successfully brought the cost of a Vietnam-bound transfer down from the $6\%$ industry average to $0.5\%$.
  • Lingo-Live Multimodality — We developed a voice-to-voice interface that explains "insufficient funds" or "network delays" in a way that feels like a helpful peer, not a cold banking error.
  • The Pulse Certificate — Giving our users a tangible PDF they can show to a US landlord to prove they are financially responsible, despite having a "thin" credit file. -File Building— Solving one of Financial Tech's biggest problems of Financial Inclusivity, Pulse helps Immigrants, Foreign Students, and Young Adults who have no financial profile be involved through its portfolio management, allowing for future applications of credits, loans, etc.

What We Learned

We learned that technology must be competent. It wasn't enough to make a "faster Venmo"; we had to build something that understood the emotional weight of a funeral in Vietnam or a birthday halfway across the world. Technically, we mastered management in Gemini 3.0, allowing us to audit the AI's logic for every financial decision it suggested.

What's Next for Pulse

  • Digital Susu/Tanda — Social savings circles that allow our family of 43 to pool money for major events like weddings or funerals.
  • Visa Vault — An AI-encrypted document manager to handle visa renewals and passport photos via Gemini 3 Flash's vision capabilities.
  • Global Cash-Out — Partnering with local "Mobile Money" vendors in Vietnam so recipients can spend their Pulse balance at the local market without needing a bank account.
