Full description

Venture-backed startup, focused on building foundational infrastructure at the intersection of fintech and Web3. We are currently in stealth mode, developing USHP- a next-generation product designed to address critical gaps in financial systems.

We are a small, deliberate team at an early stage. The people joining now will shape not just what we build, but how we build it, our culture, our standards, and our long-term trajectory. We are not looking for passengers; we are looking for builders who take ownership and thrive in environments where the path is still being defined.

Due to the nature of our work, specific product details are shared during the interview process under NDA.

USHP is building two related products: a proprietary daily predictive index of U.S. home prices, and an on-chain token whose value tracks that index. The token is collateralized by real U.S. residential properties and pays staking yield from the net income generated by the underlying portfolio. The protocol includes a full DeFi integration suite: Pendle yield tokenization, Aave/Morpho collateral, and Uniswap/Curve liquidity.
