Takeoff built what it describes as a “long-horizon agent runtime” designed to let AI agents handle end-to-end tasks across industries including lending and healthcare. Aakash Thumaty of Takeoff said the company secured several seven-figure contracts across five industries by focusing on revenue-aligned outcomes rather than inference APIs alone.<\/p>\n
The acquisition aligns with Sierra’s broader strategy of scaling industry-specific AI agents globally. Thumaty said both companies share the conviction that the largest AI businesses will be built around measurable outcomes, not model inference.<\/p>\n
“We’ve spent the last 14 months building Takeoff into a long-horizon agent runtime that enables agents to operate like humans but scale like software,” Thumaty said in a statement.<\/p>\n

Sierra’s Recent Moves<\/p>\n
Sierra has emerged as one of enterprise AI’s most valuable players, closing a $950 million Series E in May 2026 led by Tiger Global and GV at a $15 billion valuation \u2014 its third major funding milestone in roughly 18 months, up from $4.5 billion in late 2024.<\/p>\n
The company crossed $150 million in ARR<\/a> seven quarters after its February 2024 launch, with more than 40% of the Fortune 50 now counted as customers. New capital is earmarked for European and Asian expansion and for extending agents into sales and customer lifetime value<\/a> optimization.<\/p>\n Sierra’s platform has expanded beyond customer support into Agent OS 2.0, an Agent Data Platform and enterprise change management tooling. Notable deployments include Nordstrom’s voice agent “Nora” (live in five weeks), Singtel (10 weeks, resolution rates above 70%) and Cigna (eight weeks, cutting patient authentication time by 80%).<\/p>\n The company also achieved FedRAMP High authorization<\/a> in June, unlocking access to federal agencies. This month, it named SoftBank Corp. as its exclusive Japan sales partner<\/a>, building on a LINEMO deployment that delivered 97% inquiry resolution and 93% customer satisfaction.<\/p>\n Agentic AI Platforms: ROI & Architecture<\/p>\n Autonomous agent platforms are moving past pilots into production, with vendors tying architecture decisions directly to revenue outcomes and compliance requirements.<\/p>\n Grounding Agents in Systems of Record<\/p>\n Effective autonomous agents depend on systems of record. Agents resolve up to 40%<\/a> of inquiries across chat, email, voice and WhatsApp when integrated with CRM knowledge bases and workflow APIs.<\/p>\n View All<\/a><\/p>\n ServiceNow’s Autonomous CRM platform<\/a>, launched May 5, illustrates the architecture. Prepackaged actions span service, sales and field operations across government, finance, telco, healthcare and retail. The company said the platform resolves more than 100 million customer cases monthly.<\/p>\n Omnichannel Deployment Patterns<\/p>\n Autonomous agents now operate across voice, web, chat, email and messaging in what amounts to a modern omnichannel contact center<\/a> architecture. The model replaces handoff-heavy processes with multi-step autonomous execution.<\/p>\n Governed agents \u2014 those constrained by business logic and human-in-the-loop oversight \u2014 deliver deterministic outcomes in regulated environments. Clear escalation paths remain important in sectors governed by HIPAA, SOC 2 and the EU AI Act.<\/p>\n Sierra Background<\/p>\n
