## About perpetuity.finance

## Company Overview
- **One-liner**: HelloTrade (d/b/a Perpetuity) is building a blockchain-powered, mobile-first trading platform that gives global investors 24/7 access to stocks, commodities, ETFs, and cryptocurrencies, with its own DeFi venue for perpetual futures and leveraged trading.
- **Entity Type**: Private, Pre‑launch startup (Seed / early‑stage)
- **Headquarters**: New York, NY, USA
- **Founded**: 2025
- **Founders**: Kevin Tang (CEO) and Wyatt Raich (CTO) – both former BlackRock digital assets leaders

## Core Business
- Primary industries: Fintech, Blockchain, Decentralized Finance (DeFi), Crypto Trading
- Target customers: B2C global retail investors, especially those in underserved markets (e.g., Southeast Asia) who lack easy access to U.S. equities; also B2B via the Perpetuity protocol for leverage trading.
- Mission / purpose: Democratize access to traditional and crypto assets using blockchain technology, making global commerce simpler, more secure, and available to anyone with an internet connection.

## Products & Services
- **[Perpetuity (protocol/platform)]**: An all‑in‑one DeFi venue for lending, borrowing, swapping, and leverage‑trading crypto assets. Powered by a sophisticated risk engine with dynamic withdrawal limits, tiered liquidation, backstop community fund, auto‑deleveraging, and real‑time risk monitoring. The platform also aims to democratize MEV.
- **[HelloTrade (mobile app)]**: A mobile‑first, blockchain‑powered trading app (not yet launched publicly; expected end‑2025 / early‑2026) that enables users to trade U.S. stocks, commodities, ETFs, and cryptocurrencies in a single interface, using crypto rails to bypass traditional brokerage barriers.

## Market Standing
- **Valuation**: Not disclosed (seed stage)
- **Key Metric**: Total seed funding raised – **$4.6 million**
- **Notable Investors/Partners**: Lead investor: Dragonfly Capital. Also backed by Mirana Ventures and multiple angel investors.
- **Growth Signals**:
  - Founders previously led BlackRock’s pivot into crypto (iShares Bitcoin Trust, Ethereum Trust ETFs).
  - Pre‑launch, already hiring founding‑level engineers (smart contract, low‑latency Rust/C++ roles).
  - Target market: global investors who lack access to U.S. equities (e.g., Vietnam, Indonesia), a large underserved demographic.

## Competitive Advantages
- **Founder DNA**: Both founders came from BlackRock’s digital assets team, bringing deep institutional knowledge of compliance, trust, and large‑scale trading infrastructure.
- **Blockchain‑native architecture**: By tokenizing traditional assets, HelloTrade enables 24/7 trading, fractional ownership, and global access without traditional intermediaries.
- **Mobile‑first UX**: Purpose‑built to be more intuitive than incumbents like Robinhood or Revolut, with a focus on clean user interface and seamless on‑chain transactions.
- **DeFi risk engine**: Perpetuity’s sophisticated risk management system (dynamic limits, tiered liquidation, community fund) differentiates it from simpler DeFi exchanges.

## Strategic Focus
- Launch the HelloTrade consumer app globally by early 2026.
- Invest heavily in security and user education to build trust with new users unfamiliar with blockchain.
- Continue building out the Perpetuity protocol as a capital‑efficient, secure venue for perpetual futures and leveraged trading.
- Grow engineering team (currently ~4–10 employees) in New York, with hybrid presence.

## Why Work Here
- **Culture**: Fast‑paced, mission‑driven team of builders from BlackRock, top crypto firms, and high‑growth startups. Hybrid work model with in‑person preference in New York.
- **Engineering focus**: Early team members get meaningful equity and autonomy to architect core systems (matching engine, smart contracts, risk models) from scratch.
- **Perks**: Competitive salary, unlimited PTO, flexible hours, health/dental/vision benefits.
- **Impact**: Solve cutting‑edge problems at the intersection of crypto, global markets, and mobile UX – a rare chance to build a new financial primitive.
- **Work environment**: Small team (pre‑launch), high ownership, direct lines to founders.
