About
Second Nature AI is an AI-powered sales training and role-play platform founded in Israel and headquartered globally, enabling revenue teams to practice sales conversations with realistic AI personas. In October 2025, the company raised a $22 million Series B led by Sienna VC and supported by Zoom (also a customer), Bright Pixel, StageOne Ventures, Cardumen, and Signals VC, bringing total funding to over $37 million.\n\nSecond Nature's technology builds a data model of each company's sales playbook by analyzing recorded calls, marketing collateral, and scripts, then generates a library of AI-driven role-play scenarios mirroring the most common conversations reps encounter. After each practice session, reps receive personalized feedback and performance scores across dimensions like objection handling, discovery quality, and closing behavior. The platform supports 20 languages and multiple conversational styles, and new customers can deploy their first AI role-plays within an hour of onboarding.\n\nCustomers report a 33% reduction in onboarding time and a 20%+ increase in sales for teams like GoHealth. Second Nature competes with Mindtickle and Brainshark for sales readiness market share, differentiating on the depth and realism of its AI conversation engine. The October 2025 funding will support global expansion and deeper integration of personalized coaching and certification workflows into enterprise training systems.
AI quality assurance with insurance-backed warranties from Swiss Re and Greenlight Re; EU AI Act compliance assessments backed by YC and reinsurance partners for high-risk AI deployments.
About
Armilla AI is a third-party AI quality assurance and warranty company that evaluates AI models for organizations deploying AI in regulated or high-stakes contexts — assessing models against EU AI Act and NIST AI Risk Management Framework requirements for risks including bias, hallucination, robustness failures, and adversarial vulnerabilities, then providing performance guarantees backed by insurance coverage from reinsurers Swiss Re, Greenlight Re, and Chaucer. Founded in Toronto, Canada, Armilla raised $6.81 million total including a C$4.5 million seed round in February 2024 from Mistral Venture Partners, MS&AD Ventures, Y Combinator, and its reinsurance partners.\n\nArmilla's model is unique in the AI governance market — rather than just providing compliance reports, Armilla backs its assessments with insurance warranty products. An enterprise deploying a third-party AI model can purchase an Armilla warranty that pays out if the model performs differently than assessed (fails on bias, accuracy, or robustness metrics), transferring AI performance risk to insurance markets that can price and distribute it. This insurance mechanism creates financial accountability for AI quality claims that audit reports alone don't provide.\n\nIn 2025, Armilla competes in the AI governance, risk, and compliance market with Credo AI, Arthur AI, and AI audit firms for enterprise AI risk assessment and compliance tools. The EU AI Act, fully applicable by August 2025 for high-risk AI systems, is driving enterprise compliance urgency — companies deploying AI in hiring, credit scoring, healthcare, and other regulated contexts need third-party conformity assessments. Armilla's insurance-backed warranty differentiates its offering from pure advisory competitors. The reinsurer backing (Swiss Re, Greenlight Re, Chaucer) provides both capital credibility and distribution through insurance broker channels. The 2025 strategy focuses on growing EU AI Act compliance assessments and expanding the warranty product coverage to more AI deployment use cases.
