## 1. 🟦 MorphCast

### Overview
| Attribute | Detail |
|---|---|
| **Founded** | 2017 (Milan, Italy) |
| **HQ** | Milan, Italy |
| **Funding** | Bootstrapped / no major disclosed VC rounds; operates on a freemium + SaaS model |
| **Website** | [https://www.morphcast.com](https://www.morphcast.com) |

### Product Surface
- **MorphCast Emotion AI SDK / Engine** — a lightweight, **in-browser JavaScript SDK** that runs entirely on the client device (no server round-trips for inference)
- Key modules: facial expression recognition, attention tracking, engagement scoring, head pose estimation, age/gender estimation, and mood detection
- Tracks **100+ affective signals** derived from the foundational work of **Paul Ekman** (6 core emotions) and **James Russell's Circumplex Model** (valence × arousal)
- Products include: **MorphCast Interactive Video**, **MorphCast Adaptive Presentation**, and a developer-facing **SDK/API** for embedding into third-party apps

### Input / Output Modalities
| Direction | Detail |
|---|---|
| **Input** | Webcam / device camera feed (video frames) |
| **Output** | Real-time JSON emotion scores, attention/engagement metrics, demographic inferences, arousal/valence coordinates |

### SDK vs. Server-Side API
> ✅ **Ships a client-side SDK that lives inside the customer application.** Inference runs **entirely in-browser via WebAssembly/JS** — no video or biometric data ever leaves the user's device. This is MorphCast's primary architectural differentiator.

### Persistent Per-User Emotional Profile
- **No** — by design. Processing is ephemeral and on-device. No persistent emotional profile is stored. Aggregate/session-level analytics may be logged, but raw biometric streams are not transmitted or retained.

### Pricing
- **Freemium tier available** (free SDK access with usage limits)
- Paid tiers unlocked for higher call volumes, advanced signals, and commercial use
- Enterprise pricing available on request
- Pricing page: [https://www.morphcast.com/pricing/](https://www.morphcast.com/pricing/)

### Named Customers / Use Cases
- Primarily targets **EdTech, telehealth, e-learning, and digital marketing** verticals
- Named use-case partners include companies in online education and HR tech (specific enterprise names not publicly disclosed as of search date)

### Regulatory Posture
- **Privacy-first by architecture**: "server-free" design means GDPR compliance is structurally built in — no biometric data transmitted to a server
- Emphasizes compliance with EU AI Act and GDPR
- Positions the on-device approach as the answer to biometric regulation concerns
- Overview page: [https://www.morphcast.com/overview/](https://www.morphcast.com/overview/)

## 2. 🟥 Realeyes

### Overview
| Attribute | Detail |
|---|---|
| **Founded** | 2007 |
| **HQ** | London, UK (with offices in New York and Budapest) |
| **Total Funding** | ~**$33.8M** across multiple rounds |
| **Website** | [https://www.realeyesit.com](https://www.realeyesit.com) |

### Funding History
| Round | Amount | Key Investors |
|---|---|---|
| **Series A** | $16.2M | Draper Esprit, Karma Ventures, The Entrepreneurs Fund |
| **Series B** | $12.4M | Draper Esprit, NTT DOCOMO Ventures, Global Brain, Karma Ventures, The Entrepreneurs Fund |
| **Total** | ~$33.8M | (per Growjo / VentureBeat, [source](https://growjo.com/company/Realeyes_-_Emotional_Intelligence)) |

### Product Surface
- **Realeyes Attention Platform** — a research and media measurement platform focused on **attention and emotion measurement for advertising**
- Core products: **AttentionTube** (YouTube ad testing), **AttentionStream** (programmatic in-the-wild measurement), and custom studies
- Primarily a **market research / ad effectiveness** tool rather than a developer SDK
- Uses **opted-in panel participants** who activate their webcams in a controlled research environment

### Input / Output Modalities
| Direction | Detail |
|---|---|
| **Input** | Webcam video (opt-in panel), survey responses |
| **Output** | Attention scores, emotional engagement scores (happiness, surprise, confusion, disgust, etc.), second-by-second content reaction timelines, predictive viewability metrics |

### SDK vs. Server-Side API
> ⚙️ **Hybrid, but primarily server-side / managed service.** Realeyes deploys a **lightweight JavaScript snippet** into a study environment (not a persistent embedded SDK in a customer app). Video frames are processed on Realeyes' servers. The customer receives results via a **dashboard or data API**, not an embedded real-time inference engine. It functions more like a **SaaS platform + API** than a redistributable SDK.

### Persistent Per-User Emotional Profile
- **No persistent individual profile** in the advertising context — participants are panelists who consent for specific studies; data is aggregated and anonymized for reporting
- The company has been explicit that data is not used to build longitudinal individual emotion profiles

### Pricing
- **Not publicly listed** — enterprise/research contract pricing only
- Clients are typically large CPG brands, media agencies, and broadcasters
- Contact sales: [https://www.realeyesit.com/contact](https://www.realeyesit.com/contact)

### Named Customers
As cited in VentureBeat ([source](https://venturebeat.com/technology/realeyes-raises-12-4-million-to-help-brands-detect-emotion-using-ai-on-facial-expressions/)):
- **AT&T**
- **Mars**
- **Hershey's**
- **Coca-Cola**
- Additionally serves major advertising agencies and media buyers globally

### Regulatory Posture
- Relies on **explicit opt-in consent** from all panelists before webcam activation
- GDPR-compliant data handling for EU participants
- Does not operate passively or in always-on contexts — consent-gated research model is its primary compliance mechanism
- Has publicly supported standards-based attention measurement frameworks (e.g., via the **ARF** and **IAB**)

## 3. 🟩 Entropik (formerly Entropik Tech)

### Overview
| Attribute | Detail |
|---|---|
| **Founded** | 2016 |
| **HQ** | Bengaluru, India (with US presence) |
| **Total Funding** | ~**$35M+** |
| **Website** | [https://www.entropik.io](https://www.entropik.io) |

### Funding History

- Contact: [https://www.entropik.io/contact-us](https://www.entropik.io/contact-us)

### Named Customers
- Entropik has cited customers across FMCG, media, and retail sectors in India, Southeast Asia, and the US, though specific brand names are not consistently disclosed publicly
- Investor **Bessemer Venture Partners**' backing implies enterprise-grade customer validation

### Regulatory Posture
- Consent-based data collection for all biometric modalities
- Operates under **India's DPDP Act** (Digital Personal Data Protection Act, 2023) for domestic data and GDPR-equivalent standards for EU/UK clients
- Has expanded into heavily regulated markets (Middle East, Europe), suggesting active compliance investment
- The Series B funding specifically earmarked compliance infrastructure scaling

## 🔑 Key Differentiator: SDK vs. API

| Company | Delivery Model | Where Inference Runs |
|---|---|---|
| **MorphCast** | **Embedded client-side SDK** (JS + WebAssembly) | **On the user's device** — no video leaves the browser |
| **Realeyes** | Managed SaaS + lightweight JS loader | **Realeyes' servers** |
| **Entropik** | Cloud SaaS platform + REST API | **Entropik's cloud** |

> **MorphCast is the only one of the three that ships a true embedded SDK** designed to live inside a customer's web application or product, with all inference happening locally. This makes it the most suitable choice for real-time, privacy-sensitive, or latency-constrained deployments. Realeyes and Entropik are better characterized as **B2B research platforms** accessed via managed service contracts.
