Massive is a venture capital fund that invests $500k-$2M in deep-tech companies at the "inflection point" when they've moved from potential to proven traction—after seed but before traditional growth rounds—rather than leading deals themselves. The fund was built unusually by starting with the founders' own capital and SPVs before creating a traditional fund structure, and enforces an "equal effort" rule where they ignore spray-and-pray pitches but promise to respond to founders who clearly show why their company fits Massive's thesis.
