Silicon Catalyst Angels is an accredited angel investment group spun out in July 2019 from Silicon Catalyst, the semiconductor-focused incubator and accelerator based in Silicon Valley, CA, USA. The group consists of seasoned semiconductor industry investors, engineers, and executives who invest individually in startups that have been vetted or admitted into the Silicon Catalyst ecosystem — especially in next-generation silicon hardware, semiconductor IP, sensors, photonics, and related deep tech areas.

Pre-Seed / Seed: Core focus — angel-level investments enabling early institutional capital for hardware- and silicon-oriented startups.
Series A: Also provides access to Series A funding for portfolio companies once they’ve proven traction and fit for early institutional scaling.

• Silicon Catalyst Angels’ members invest individual accredited capital in startups — aggregated group commitments historically total several hundred thousand dollars for funded deals, though no fixed minimum/maximum check is published.
Equity Taken:
• The group does not publish a fixed ownership percentage it always takes in every investment (common for angel networks). Terms — including equity stake and valuation — are negotiated per deal with founders and participating investor members.
• Industry norms for seed/angel rounds indicate that collective dilution across all early investors commonly ranges ~10%–25% of a startup’s equity (overall across all participants), with individual investors or groups taking meaningful minority positions consistent with their capital contribution.
• Because Silicon Catalyst Angels consists of individual accredited angel members investing directly, a founder may expect the group’s participation to contribute to minority ownership positions after negotiation — not a controlling stake, and dependent on valuation and total round composition (i.e., proportionate to total raise).
Equity Structure: As with most angel investments, terms may include priced preferred equity, SAFEs, or convertible notes based on founder/investor agreement (this is standard practice for angel groups, because Silicon Catalyst Angels does not publicly document unique instrument terms).

Submission Method: Startups can submit a pitch via the Silicon Catalyst Angels pitching form or directly reach out through the website; because the group is tied to the Silicon Catalyst pipeline, many funded startups come from that incubator’s funnel.
Investor Membership: Accredited angels interested in participating can apply to join the network and attend investor meetings where deals are reviewed. 

Sector Focus: Deep tech and hardware — semiconductors, photonics, silicon IP, sensors, MEMS, advanced computing, next-gen materials.
 Geography: Focused on U.S.-based and globally deployable deep tech companies (especially startups connected to the Silicon Catalyst ecosystem).
Stage: Seed and early institutional (Series A). 
Company Profile: Strong technical founding teams building scalable hardware-centric ventures with demonstrable market potential.

Typical Angel Network Workflow:
 • Initial Intake: Founders submit deck, business model, and team bios for review.
• Screening & Pre-Review: Early evaluation by group members or a screening committee for technology relevance and market potential.
• Pitch & Discussion: Founders present to Silicon Catalyst Angels members at an investor meeting.
• Due Diligence & Negotiation: Interested members conduct diligence and negotiate terms with the founders.

Strategic Capital: Early angel and seed capital from semiconductor-savvy accredited investors.
 Deep Expertise: Mentorship and domain guidance from industry veterans with silicon/hardware experience.
 Network Access: Visibility to both angels and larger VCs interacting with the Silicon Catalyst platform’s broader network.
 Follow-On Support: Opportunities to participate in Series A alongside early supporters as companies scale.
