San Francisco's blockchain and cryptocurrency funding activity spans a wide range of stages and check sizes across the 34 companies shown here. The largest rounds are concentrated in early 2025: Phantom closed a $150M Series C on January 16, and Movement Labs followed with a $100M Series B on January 8 — both the same month. Portal to Bitcoin's $50M Series A in August 2025 and Andalusia Labs' $48M Series A in December 2023 are the next largest disclosed rounds. Series A is the most common labeled stage with eight companies, while nine companies raised at seed, ranging from $3M (o1.exchange, Rakurai, Nubila, NodeShift) to $11M (Gameplay Galaxy).
Deal flow in the set runs from Superstate's November 2023 Series A through Lava's October 2025 raise, with activity spread across both 2024 and 2025 rather than clustering in any single quarter. Three companies — Mesh, Plume Network, and Securitize — reported rounds at undisclosed amounts, all categorized as Series Unknown. Pre-seed activity includes five companies, with Human's $7M in February 2025 the largest of that cohort.
