All 5 sources verified from disk snapshots. source-0 (modal.com/blog/modal-series-c): Modal's own announcement — confirms $355M, $4.65B post-money valuation, General Catalyst and Redpoint as leads, Menlo/Bain Capital Ventures/Accel as new investors, >$300M ARR up fivefold from September 2025, over 1B sandboxes launched, sandboxes >1/3 of revenue, all quoted testimonials (Scott Wu, Brian Ichter, Andy Fang) verified verbatim (truncated but not misrepresented). source-1 (siliconangle.com): Confirms two-tranche structure ($2.5B first tranche, $4.65B second), $300M ARR from $60M, Bernhardsson quote 'The last six months have been driving everything' confirmed verbatim as attributed to SiliconANGLE. source-2 (techstartups.com): Confirms Series B at $87M led by Lux Capital in October 2025 at ~$1.1B valuation. source-3 (benzinga.com): Confirms platform details (2021 founding, Bernhardsson and Bubna, 13 cloud providers, sandbox >1/3 revenue, scale to 1,000 GPUs in minutes). Note: Benzinga erroneously reports '$400 million' in ARR — the article correctly uses '$300 million' sourced from Modal's own blog and SiliconANGLE. source-4 (letsdatascience.com): Confirms board seats for General Catalyst and Redpoint (as attributed to Let's Data Science), $300M ARR, two-tranche structure. Reuters is cited indirectly via SiliconANGLE and Let's Data Science; this is proper secondary attribution.

All key claims are supported by the cited sources. The $300 million ARR figure is correct per Modal's own blog and SiliconANGLE — Benzinga's '$400 million' appears to be a reporting error in that outlet. No fabricated specifics, no hallucinated quotes, no misattributed claims found. Truncated quotes (Andy Fang, Scott Wu, Brian Ichter) are accurate to the source and the omissions do not change the meaning.

High-quality funding announcement with thorough sourcing, accurate figures, and proper attribution. All five sources verified; all quotes confirmed verbatim from cited outlets. No corrections needed. Approved for publication.
