## 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

## DuoSoft

DuoSoft positions itself as a purpose-built technology partner for organizations rather than a generic dev shop. Its five stated capabilities are custom software development, AI integration, digital transformation consulting, business analysis and corporate training. In practice that means the company starts with a discovery call to map goals, users, data and existing systems, then helps prioritize what to build first based on business impact, cost and risk before shipping working increments.

The solutions DuoSoft delivers are centered on operational software: management systems and internal operations tools, request and approval workflow automation, reporting and decision-support dashboards, integration and improvement of legacy systems, and AI-powered process assistants that give staff faster access to internal knowledge. The team also produces technical analysis, requirements documentation and a prioritized backlog, which is often the deliverable enterprises need before any code is written.

Its working principles emphasize transparent decisions, direct access to decision makers and early feedback loops. DuoSoft states that it uses AI across analysis, development and quality assurance to move faster and reduce errors, while planning delivery time, integration risk, security and maintenance as a single system. Corporate training is offered alongside delivery so that teams can actually operate what gets built. The company is based in Ankara, Turkey, publishes a general contact address, and shares project work through its LinkedIn presence.

**Pricing & Plans:** DuoSoft does not publish fixed packages or per-seat rates. Pricing is quoted per project after a discovery call, and engagements are scoped around requirements, delivery phases and ongoing maintenance or training needs.

- **Custom software development:** Management systems, operations dashboards and internal tools designed around the way your organization already works.
- **AI integration with clear boundaries:** AI features embedded into business processes with defined data security and usage limits, so teams know what the model can and cannot touch.
- **Digital transformation roadmap:** A prioritized plan covering software, processes, data and the team capabilities needed to execute it in stages.
- **Business analysis and backlog:** Requirements, user flows, acceptance criteria and a prioritized backlog documented before implementation begins.
- **Corporate AI and software training:** Practical sessions that help internal teams operate new software and adopt AI tools safely in day-to-day work.

**Strengths:** End-to-end coverage from discovery and business analysis through delivery, training and maintenance; Explicit emphasis on defined data security and usage boundaries for AI features; Staged delivery with working increments and regular feedback rather than a single big-bang release; Corporate training included as a capability, so internal teams can operate the delivered software

**Limitations:** No published pricing, packages or self-serve trial, so evaluation requires a sales conversation; Enterprise-oriented consulting model is likely overkill for very small teams or simple one-off builds; Public product documentation and case studies are limited, making independent comparison harder
