About Supermoon Capital

Supermoon Capital is an early-stage venture firm whose branding suggests a thematic seed and pre-Series A focus, with limited specific data on healthcare specialization or AI emphasis from the inputs provided. Firms operating in this profile typically deploy seed checks in the range of two hundred fifty thousand to one and a half million dollars, with reserves for follow-on, and the strategy may include thematic depth in one or two verticals depending on the partners’ backgrounds. The natural fit is a focused seed company with a defined buyer, an articulate founder thesis, and early evidence of customer pull or technical defensibility. Healthcare AI founders can engage if the company aligns with the firm’s specific themes, which founders should research independently via the firm’s portfolio and partner backgrounds before reaching out. Without confirmed healthcare specialization, founders should treat this as a generalist seed firm and should not expect deep clinical or regulatory coaching. Companies pursuing therapeutics, complex devices, or healthcare businesses that require deep regulated-market expertise are unlikely to find specialist value here. The best entry path is a warm introduction from a portfolio CEO, a fellow seed investor, or an operator in the firm’s network. Direct outreach to partners on LinkedIn or via the firm’s website is acceptable for cold contact, paired with a tight executive summary, traction signals, and a clear articulation of why the company aligns with the firm’s stated themes. Founders should research the partners individually before tailoring outreach.
