## Appen

Appen is one of the oldest pure-play AI data companies, tracing its roots to 1996 when it began building human-labeled datasets for speech recognition and NLP. Over three decades it supported successive generations of model development — search relevance in the 2000s, machine translation, deep-learning vision annotation, Transformer-era semantics, GPT-3 scale corpora, RLHF for conversational AI, and now agentic and multimodal foundation models.

Today Appen positions itself around six specialised capability areas: Frontier Alignment (chain-of-thought reasoning traces, SME RLHF, supervised fine-tuning demonstrations, adversarial red teaming), Agentic AI (golden trajectories, RL environment design, failure-mode taxonomies, SWE-driven evaluation), Multimodal and Speech AI (multilingual ASR and conversational corpora, expressive TTS annotation, VLM training data, video action labelling), Physical AI (LiDAR point-cloud annotation, multi-camera sensor fusion, robotics demonstration trajectories, world-model rollouts), Model Integrity (hallucination benchmarking, bias detection, regulatory audits and continuous monitoring), and Research Services (context engineering, calibrated LLM-as-a-judge, synthetic data and custom benchmarking).

Delivery runs through Appen's AI Data Platform (ADAP), which blends automation with human oversight, and the company cites SOC 2 and ISO 27001 certification, 500+ global locales, and a client roster that includes major cloud, search, retail and aerospace organisations. Appen does not publish self-serve pricing; engagements start with a scoping conversation and are quoted per project, so cost depends on data volume, language coverage, modality and annotation complexity.

**Pricing & Plans:** Enterprise/contact-for-pricing. Appen does not publish self-serve plans; projects are scoped and quoted individually. Appen also sells off-the-shelf (OTS) datasets and crowd/contractor workforce programs with separate terms.

- **Frontier alignment data:** Chain-of-thought reasoning traces, SME-level RLHF, supervised fine-tuning demonstrations and adversarial red teaming for the most capable models.
- **Agentic AI datasets:** Golden trajectories, RL environment design, failure-mode taxonomies and software-engineering-driven deep evaluation for autonomous agents.
- **Multimodal and speech corpora:** Multilingual ASR and conversational speech data, expressive TTS annotation, vision-language model training data, video action labelling and voice-agent evaluation.
- **Physical AI annotation:** LiDAR point-cloud labeling, multi-camera sensor fusion, robot demonstration trajectories, world-model rollouts and embodied interaction logs.
- **Model integrity and evaluation:** Hallucination benchmarking, bias detection, regulatory audits and continuous monitoring, plus independent model evaluation.
- **AI Data Platform (ADAP):** A production platform that combines automation with human oversight, with SOC 2 and ISO 27001 certification and 500+ locales covered.

**Strengths:** Three decades of annotation methodology, tooling and workforce management experience; Very broad coverage: frontier alignment, agentic, speech, multimodal, physical AI and evaluation in one vendor; 500+ locales and multilingual expertise that most in-house teams cannot match; Enterprise-grade security posture (SOC 2, ISO 27001) and publicly listed governance

**Limitations:** No transparent self-serve pricing; every engagement requires a sales/scoping cycle; Enterprise-oriented contracts can be heavy for small teams or indie developers; Quality depends on workforce management, so results vary by project and locale; Overlaps with many cheaper specialist annotation vendors, making vendor selection non-trivial

## SuppCo

SuppCo positions itself as a companion app for supplement users rather than a shop. You add the products you already take, and SuppCo rates each one with its TrustScore system, a 29-attribute quality measure that weighs manufacturing standards, third-party testing, label accuracy and inactive ingredients. The score and the underlying evidence are shown openly, so a 9.8 "Excellent" rating on a fish oil is explained rather than asserted.

The other half of the product is personalisation. Stack analysis reviews your whole regimen for nutrient coverage, dosing and redundancy, then compares it against your goals and returns a StackScore with specific suggestions. SuppCo's expert panel, which includes physicians and nutrition coaches known for their work in functional medicine, contributes protocols for goals such as longevity, gut health, fitness, weight management and fertility, and a research center summarises what thousands of studies say about individual nutrients and popular ingredients.

Alongside the app, SuppCo runs a Buying Club that sells vetted products directly and returns a share of spend as credits, plus a community and editorial layer. The service is free to use, with an optional Pro subscription for deeper personalisation, and SuppCo now operates as part of Function following that acquisition.

**Pricing & Plans:** Freemium. SuppCo is free for all users, including the stack tracker, TrustScore product ratings and research content. An optional Pro subscription unlocks advanced personalization tools, and the SuppCo Buying Club offers 30% back in Supp Credits on purchases.

- **TrustScore® quality ratings:** Scan or search products to see a quality rating built from 29 attributes covering manufacturing standards, testing benchmarks and inactive ingredients.
- **Personalized stack analysis:** Get a StackScore for your routine along with nutrient-level coverage, dosing feedback and gap analysis against your health goals.
- **Expert-designed protocols:** Follow regimens designed by clinicians and functional-medicine experts for goals like longevity, gut health, fitness, weight management and fertility.
- **Tracker with reminders:** Smart scheduling, reminders and daily intake logging so you actually stick to your supplement routine.
- **Research center and community:** Browse nutrient explainers, goal guides and protocols informed by thousands of published studies, plus a members' community.

**Strengths:** TrustScore turns supplement quality into a plain numeric rating with visible criteria; Stack analysis catches overlaps, dosing issues and coverage gaps across a whole routine; Protocols contributed by named, credentialed experts rather than anonymous listicles; Free core tier with no paywall on basic tracking and product research

**Limitations:** Health guidance is educational and not a substitute for professional medical advice; Pro tier required for the most advanced personalization features; Vendor-supplied listings and scores may not cover every niche or regional brand; App-centric experience, so desktop-only users get less value
