Circleback's seed post of 26 November 2024 is signed by Ali Haghani and names Kevin as co-writer of the first code. Investors are from that post, and Neo from UBC Computer Science's news story of March 2024, which says the founders received $125K through the Neo Accelerator in 2023 and $500K on joining Y Combinator. Angels the seed post names are listed without other detail. Circleback's blog sitemap, read 6 November 2026, has no funding post after the seed, and a web search found no later round. The seed post gives the $2.5M seed but no total, and it isn't clear whether the Neo money is part of it, so totalRaised is left out. No source states a valuation.",
