Seraph Group
VC Fund
Foster City, United States
Seraph Group is a VC fund in Foster City focused on Software and Health Care. It all began in 2003, with a conversation outlining the inefficiencies in Angel investing in addition to the difficulties entrepreneurs face while raising start-up capital. Few investment groups specialize in investing $50k to $2 million in early-stage companies and even fewer bring a broad value-add network to support entrepreneurs. The Seraph Investor Network was founded with the vision of providing capital and support in an expedient and efficient manner without geographic prejudice. Our Investor Network reaches 91+ cities and spans three continents. The reach provides valuable expertise to entrepreneurs and investors. Seraph Group is comprised of a diverse group of business leaders, entrepreneurs, and technology leaders across wide array of different industries. By leveraging this expertise, Seraph Group is able to evaluate and invest in venture scalable opportunities across most industries. Investments range from $50K to $1.5 million and can participate along any financing stage of the company. While Seraph Group is comprised solely of angel investors, the investment process mimics a traditional venture capital firm where there is a fund managed by a small investment team. This pool of smart capital brings singular access to a prestigious group of individuals that are all invested in an entrepreneur's business and its success. In today' market, companies have proven that only a relatively small amount of capital infusion, under $1 million, is enough to build a venture scalable business. However, most entrepreneurs will attest, that raising $500K to $1.5 million, is the hardest amount of capital to raise because it is too small for traditional venture firms. Seraph Group's focus is to fill this unmet need in the market for professional, smart capital. The primary investment criteria for companies raising money is for it to be a venture-scalable business and not a life-style business. Seraph Group will consider investing in any round of financing and has often invested alongside later-stage venture firms.

| Lightsprint provides an AI-native product development platform that supports collaborative software development on a shared codebase. The platform offers a web-based workspace where product managers, designers, and engineers describe changes in plain English, review visual plans, and guide fleets of background coding agents. Its Visual Plan Modeturns requirements into structured task breakdowns, mockups, and codebase-aware specifications before any code is written. Parallel cloud agents then execute these plans in isolated environments, running tests and generating pull requests against existing repositories. Each change includes a live preview URL so non-technical teammates can review behavior before merge. Lightsprint is model- and tool-agnostic, integrates with systems such as GitHub, Linear, and Slack, and is designed to preserve institutional context about code patterns and product decisions over time. | $6.1M / Seed / Oct 13, 2026 | ||
