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.

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.
Adept AI raised $415M to pioneer computer-use AI agents; its core research and agent team moved to Amazon in 2024 in a landmark talent acquisition while the company continues developing ACT-1 for enterprise automation.
Adept AI was founded in 2022 by a team of former OpenAI, DeepMind, and Google Brain researchers to build AI that can take actions on computers — navigating software interfaces, filling forms, and executing multi-step workflows in any application. Its ACT-1 model demonstrated the ability to control web browsers and desktop applications through natural language instructions, pioneering the computer-use agent paradigm that Anthropic later commercialized with Claude's computer use feature.
