Trusted by Builders & Investors

"Obsidian Cipher didn't just invest — they parachuted in three senior engineers who rebuilt our data pipeline from the ground up. We went from 3-hour batch jobs to sub-second streaming in 6 weeks."

Maya Chen
CTO, Stratum AI (Series B)

"The combination of capital and technical expertise is genuinely rare. Obsidian Cipher caught architectural issues in our platform that would have cost us millions at scale — before we even closed the round."

JO
James Okafor
CEO, VaultEdge (Fintech)
