cielo24 is a technology company specializing in a human-in-the-loop (HITL) platform that transforms media content into actionable intelligence, offering services like captions, transcripts, audio description, dubbing, data labeling, and localization for English and foreign languages.[1][3][4] It serves clients in online education, enterprise, news, entertainment, business services, and technology sectors, solving problems of accessibility compliance (e.g., WCAG, ADA, HIPAA), content discoverability, global reach, and user engagement by converting unstructured media into searchable data like indexes and media intelligence.[1][2][3][4] With 11-50 employees based in California, cielo24 emphasized high accuracy (99%), fast turnaround (as quick as 2 hours), low per-minute pricing without setup fees, and 24/7 support, but operations are winding down after its acquisition by Rev, with services concluding on September 30, 2025.[1][4]
Founded in 2012 in Santa Barbara, California, cielo24 emerged to address growing demands for multimedia compliance, discoverability, and engagement in media-heavy markets.[3] The company built its platform around creating high-quality, searchable data from unstructured media, starting with core offerings in captions, transcripts, and media intelligence tailored for scalable, integrated solutions.[2][3] Early traction came from partnerships with large media platforms in education and enterprise, leveraging proprietary HITL technology combining AI automation with human expertise for precision in captioning and data services; it evolved to include localization, audio description, and data labeling, positioning itself as a leader in accessibility before the Rev acquisition announcement.[1][4]
cielo24 rode the wave of rising accessibility mandates (e.g., ADA/WCAG) and AI-driven media intelligence trends, capitalizing on surging demand for inclusive multimedia amid remote learning, global content distribution, and compliance laws in education, enterprise, and entertainment.[2][3][4] Its timing aligned with explosive growth in video content and AI/ML needs for high-quality training data, where HITL approaches bridged gaps in pure automation for nuanced tasks like captioning and localization.[1][3] Market forces like expanding online platforms and localization for global audiences favored its scalable, low-cost model, influencing the ecosystem by setting benchmarks for compliant media processing and enabling partners to boost discoverability and engagement; however, the Rev acquisition signals consolidation in speech-to-text and captioning, potentially shifting focus amid competitors like Otter.ai and 3Play Media offering broader live services and integrations.[3][4][6]
Post-acquisition by Rev, cielo24's standalone services end September 30, 2025, with users urged to migrate, likely integrating its HITL tech into Rev's transcription portfolio amid intensifying competition from players like 3Play Media with superior live captioning, integrations, and SLAs.[4][6] Trends in AI-powered accessibility, multimodal data labeling for LLMs, and global video localization will shape its legacy, potentially amplifying Rev's offerings in enterprise and education. Its influence may evolve through embedded tech in larger platforms, reinforcing HITL standards, but former customers face disruption—watch for Rev's execution on promised continuity to sustain cielo24's momentum in compliant media intelligence.[4][6] This closure underscores the startup ecosystem's volatility, where even specialized innovators like cielo24 must navigate acquisition dynamics to endure.
cielo24 has raised $5.0M across 1 funding round. Most recently, it raised $5.0M Series A in October 2015.
