## Questions

### Who runs investment decisions at Walden Catalyst?

Co-Founders Young Sohn and Lip-Bu Tan serve as Managing Partners and lead investment decisions together. Sohn is the former President and Chief Strategy Officer of Samsung Electronics, where he ran a $20 billion corporate venture and M&A operation. Tan was the longtime CEO of Cadence Design Systems, the electronic design automation leader. Their combined operating experience inside the semiconductor supply chain directly shapes the firm's investment committee discussions and technical diligence.

### How does Walden Catalyst source proprietary deal flow?

The firm sources deal flow through deep technical networks inside university AI and semiconductor labs, corporate R&D groups, and the fabless chip ecosystem. Sohn's relationships across Samsung's component and foundry divisions and Tan's access to chip design tooling and EDA customers provide a sourcing channel distinct from the traditional venture partner-introduction model. The partnership can identify technical founders before they formally launch a company, often at the research-paper or stealth-project stage.

### Which sectors does Walden Catalyst explicitly avoid?

Consumer internet, mobile apps, and capital-light enterprise SaaS fall outside the firm's core thesis. Walden Catalyst focuses on capital-intensive deep tech where semiconductor innovation, data-center architecture, and AI training infrastructure create defensible moats. The partners' backgrounds do not align with the rapid iteration and network-effect scaling typical of consumer software, and the firm has not made public investments in those categories.

### How are the founders' prior roles at Samsung and Cadence relevant to portfolio companies?

The founders' operating backgrounds give Walden Catalyst the ability to advise on chip tape-out strategy, foundry selection, and EDA tooling — decisions that can determine whether a semiconductor startup survives its first fabrication cycle. Sohn's Samsung tenure opens conversations with one of the world's three leading foundries, while Tan's deep relationships across the fabless design ecosystem can accelerate a portfolio company's path to a first silicon prototype and anchor customer.
