## 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

## Deferred

Deferred positions itself as the "no fee" 1031 exchange provider. A 1031 exchange lets a real estate investor defer capital gains tax by reinvesting the proceeds of a sold investment property into a replacement property, but the law requires a neutral Qualified Intermediary to hold the money in between. Most QIs charge a fee (often $1,000–$1,500 or more) and keep any interest the funds earn. Deferred flips that: it charges nothing on a standard forward exchange and passes a share of the interest back to the client.

The company says it has completed more than 8,000 exchanges and holds client funds at commercial bank partners in segregated, individually FDIC-insured accounts, with coverage options up to $175M plus a $25M fidelity bond and $5M errors-and-omissions policy. A team with over 200 years of collective 1031 experience handles the paperwork, deadlines and identification forms.

Pricing is transparent and exchange-type dependent: standard forward exchanges are free with interest sharing, while reverse exchanges start around $7,000 and improvement (build-to-suit) exchanges start around $7,500 because of their added complexity. The site advertises a perfect 5-star record on Google and Trustpilot.

**Pricing & Plans:** Standard forward exchanges are free with interest sharing; reverse exchanges start around $7,000 and improvement exchanges from about $7,500. Reverse and improvement exchanges are quoted individually.

- **No-fee forward exchange:** Deferred charges $0 on standard forward 1031 exchanges and instead earns from the interest generated by escrowed proceeds.
- **Interest sharing:** Unlike most QIs that keep the interest, Deferred pays a share of the interest earned on your exchange funds back to you.
- **Secured, segregated funds:** Proceeds are held in individually FDIC-insured accounts at commercial banks, with a $25M fidelity bond, $5M E&O cover and coverage options up to $175M.
- **All exchange types:** Supports standard forward exchanges plus more complex reverse and improvement (build-to-suit) structures with dedicated support.
- **Expertise and guidance:** A team with 200+ years of collective 1031 experience guides deadlines, 45-day identification and paperwork.

**Strengths:** No fee on standard forward exchanges; You keep a share of the interest your funds earn; Funds held in segregated, FDIC-insured accounts with high coverage limits; Advertises a perfect 5-star review record on Google and Trustpilot

**Limitations:** Reverse and improvement exchanges carry substantial fees (thousands of dollars); Interest-sharing economics depend on prevailing rates and hold duration; Services are US-specific and tied to IRS 1031 rules
