Seraph Group

Tuff Yen, the firm's founder, serves as Managing Partner and leads investment decisions. The firm's process is distinctive because it involves a network of over 400 limited partners—primarily current and former C-suite technology executives—who participate in evaluating deals. Final investment committee authority rests with Yen and the core investment team, but the LP network's technical feedback is structurally embedded in due diligence.

Seraph's primary sourcing channel is its own limited partner network of 400-plus technology executives. These LPs, drawn from companies like Oracle, Apple, and Intel, frequently encounter early-stage companies through their own professional orbits and bring those opportunities to the firm. The firm also receives referrals from co-investors and its existing portfolio founders, creating a proprietary top-of-funnel that relies less on inbound pitch decks than on operator-led introductions.

Seraph typically structures investments through individual deal vehicles rather than raising traditional blind-pool venture funds. This allows its 400-plus network of executive LPs to opt into specific investments on a deal-by-deal basis. The structure gives investors granular control over their venture exposure and aligns with the firm's model of engaging LPs who can also contribute operating expertise to the companies they back.

Seraph focuses on seed and early-stage investments, often participating as one of the first institutional checks into a company. The firm's deal-by-deal vehicle structure means investment amounts vary by opportunity and LP interest. The firm has backed over 100 companies since inception, with a portfolio concentrated in enterprise software, AI, digital health, fintech, cybersecurity, and mobility.

The firm's portfolio has produced exits through acquisitions by major technology acquirers. Autonomous driving company Cruise was acquired by General Motors in 2016 (per Reuters, 2016). Mobile security company Lookout reached a valuation exceeding $1.5 billion. Other exits in the firm's history include companies acquired by Google, Microsoft, and Cisco, reflecting the enterprise and infrastructure tilt of its portfolio.

Seraph's network is composed primarily of practicing and former technology operators—CTOs, VPs of engineering, and product leaders—rather than purely financial investors or multi-generational wealth families. This creates a technical evaluation layer inside the firm's due diligence process that is more commonly found inside corporate venture arms. The network operates as both a sourcing channel and an active post-investment resource for portfolio companies.

The firm's geographic focus is predominantly North America, with its headquarters in Milton, Georgia. Seraph has also made selective investments in Israel, leveraging its LP network's connections in technology hubs internationally. The firm's core deal flow and portfolio concentration remain US-centric, aligned with the professional networks of its executive investor base.
