What Curve Labs does
Curve Labs is a privately-held applied research lab founded in 2024 and headquartered in Singapore (incorporated as an LLC), with operational presence in San Francisco, Chicago, Hong Kong, Wuxi, and Nanjing. The company builds the empathic layer for AI systems, developing emotionally intelligent AI personas and tools targeted at developers, enterprises, and consumer applications. Its stated mission is to create AI personas that exhibit human-like emotional intelligence capable of meaningful, unprompted interactions across customer support, mental wellness, creative writing, education, AI agents, and robotics use cases.
The company's core product is ThinkFeel, an Emotion AI API and SDK (Beta v0.1.2, launched November 2025), powered by the proprietary Emotionally-Aware Mixture-of-Agents (EmMA) architecture — a novel LLM-powered multi-agent system that simulates region-specific brain functions via think-feel-reply frameworks incorporating neurological factors, emotional states, and linguistic nuance. Supporting capabilities include HEXACO-based personality profiling, multimodal understanding (image, sticker, voice), jailbreak prevention, and message-ready API chunks. Distribution occurs through an OpenAI-compatible completions endpoint, a TypeScript SDK on NPM, GitHub cookbooks, and consumer-facing Telegram bots (Emma and Andre) that serve as live product demonstrations. Infrastructure dependencies span Groq, Cerebras, OpenAI, Vercel, Stripe, Telegram, and Cloudflare.
The business model is usage-based API pricing at near-inference cost during Early Access Beta (with rate limits of 25 req/min, 100 req/hr, 500 req/day), supplemented by custom persona development during onboarding and an alpha x402 payment rail. Go-to-market is API-first and product-led, with developer relations, grassroots AI communities (AI Tinkerers, The Generative Beings, AI Builders), event presence (Token2049, Tech Crunch Disrupt, Open Robotics AI Forum, NUS Unicon), and strategic partnerships (NVIDIA Inception, BytePlus/ByteDance, Embodied Agents Lab of Singapore, Founders Inc Canopy). Disclosed customers include Unreel.ai (enterprise, Media & Entertainment) and a confidential wellness partner (campus-based mental wellness pilot). The company has no publicly disclosed funding rounds and no disclosed revenue.

Curve Labs competitors and assessment
Company assessmentBroad incumbents
- Anthropic: Anthropic's Claude emphasizes personality and tone as core capabilities and is used as foundation model infrastructure; comparable to OpenAI as both partner-foundation-model and indirect competitor in emotional AI.
- OpenAI: OpenAI's GPT models and Custom GPTs cover conversational personas broadly; Curve Labs explicitly integrates OpenAI SDKs and treats OpenAI as a research partner, while also competing against its increasingly emotional base models.
- Affectiva (Smart Eye): Affectiva (acquired by Smart Eye) pioneered emotion-sensing AI for automotive, media, and research — a broader incumbent in emotion AI with overlapping technology DNA but a different vertical focus.
Emerging players
- Tavus: Tavus builds personalized AI video agents with human-like delivery, intersecting Curve Labs' AI-influencer and emotionally resonant persona use cases.
- Beyond Presence: Beyond Presence creates real-time conversational AI avatars with facial animation — an emerging peer whose avatar + emotional persona combination closely matches Curve Labs' EmMA-style vision.
Direct peers
- Replika: Replika is a consumer companion AI that prioritizes emotional connection and authentic persona behavior — a direct comparator for Curve Labs' companion apps / mental wellness segment.
- Hume AI: Hume AI builds an 'empathic voice interface' and emotion-measurement API (EVI) that infers emotional state from voice and expression — the closest direct competitor to Curve Labs' ThinkFeel emotion AI API across both modality and product packaging.
- Character.ai: Character.ai enables creation of persona-based conversational agents with distinct emotional styles, directly overlapping Curve Labs' creative writing / entertainment and persona-development segments.
- Inflection AI: Inflection AI built 'Pi' as an emotionally intelligent personal assistant, positioning empathy as the core differentiator — a strategically comparable, well-funded effort in the same emotional-AI agent category.
- Soul Machines: Soul Machines creates autonomously animated, emotionally responsive digital humans and AI avatars for customer experience — overlapping directly with Curve Labs' emotionally intelligent persona and avatar use cases.
