## LightOn

LightOn is a European AI company, founded in Paris and researching large language models since 2016, that now positions itself as "the search engine for AI agents." Its central product, LightOn Core, ingests an organization's entire document estate — contracts, claims files, tickets, reports, scans and handwriting — and turns it into one governed, machine-readable source of truth. Rather than bolting a chatbot onto a data warehouse, LightOn attacks the retrieval problem directly, which is why its marketing leans on the claim that an in-house RAG typically costs at least twice as much as LightOn Core across a three-year production horizon.

Above the retrieval layer sit LightOn Apps: packaged use cases that map to real operational jobs, such as searching across all data, comparing information against a ground-truth version, extracting and cross-checking week-long reading tasks overnight, monitoring recurring faults, scoring suppliers with page-level justification, and mapping a research field in days. Each is illustrated with concrete customer narratives from public administration, insurance, procurement and fleet operations.

For builders, LightOn offers an API with a 15-day test access and the underlying models — including LightOnOCR-3 for document understanding — which are open-weighted and widely used by the research community. The company is explicitly European and sovereign-AI oriented, participating in EU projects such as DeployAI, OpenEuroLLM, LLMS4EU and SCRIBE. Pricing is enterprise and quote-based: prospective buyers book a 45-minute session with an AI architect and request a demo.

**Pricing & Plans:** Enterprise pricing, quoted per organization. LightOn does not publish self-serve plans. Developers can request a 15-day API test access with no commitment, and buyers typically start with a demo call with an AI architect.

- **Enterprise Document Search:** Turns a full document estate into one governed, machine-readable source of truth, so answers cite the pages that support them.
- **LightOn Core Platform:** On-premise or sovereign-friendly deployment of the retrieval stack, with LightOn's own open-weight models underneath.
- **Ready-Made Use-Case Apps:** Prepackaged agents for finding information, comparing against ground truth, extracting and cross-checking, monitoring weak signals, scoring with justification and mapping research.
- **Developer API & Integrations:** Production-grade parsing, extraction and retrieval for teams wiring document intelligence into their own products.
- **Frontier Open-Weight Models:** State-of-the-art document understanding models such as LightOnOCR-3, developed by a lab doing AI research since 2016.

**Strengths:** Purpose-built retrieval stack rather than a generic assistant wrapper; Clear, operational use cases backed by named industry scenarios; Open-weight models with strong research pedigree and community adoption; European, sovereign-AI positioning suited to regulated buyers

**Limitations:** Enterprise/quote-based pricing with no public self-serve tiers; Full value depends on having a large, messy document estate to index; Deployment and governance decisions add evaluation time versus plug-and-play tools

## Scale

Scale positions itself as the infrastructure layer for reliable AI - the data, evaluations and deployment support that sit underneath working systems rather than a single consumer-facing model. Founded in 2016, it built its reputation supplying training data and labelling capacity to the autonomous vehicle and then the generative AI wave, and now describes itself as powering a large share of the world's leading generative AI model builders.

The offering spans three broad areas. Data covers sourcing and expert annotation for training and fine-tuning, including RLHF-style preference data. Evaluation covers public leaderboards and private benchmarks used to measure model capability and safety. Applications covers the build-and-deploy side: identifying a viable use case, constructing the system and owning the outcome, with agentic AI for enterprise operations.

Scale's customer list leans heavily enterprise and public sector, including large technology companies, healthcare providers, media organisations, energy companies and government defence programmes. Because engagements are scoped rather than self-serve, pricing is arranged through a sales process, and the platform is aimed at organisations with serious data volume, strict compliance needs and a mandate to put AI into production.

**Pricing & Plans:** Contact for pricing. Scale does not publish rates; engagements are scoped through a sales conversation and depend on data volume, services and programme complexity.

- **Data Engine:** Human-sourced and expert-annotated training data, including specialist contributors with advanced degrees, at the quality bar frontier labs require.
- **Model evaluation & benchmarks:** Public leaderboards plus private benchmarks that test model capability and safety for the most ambitious AI developers.
- **Enterprise AI applications:** Platform and services teams that pick the right use case, build the system and take ownership of the outcome.
- **Agentic deployment:** Agentic systems designed around measurable business outcomes across private equity portfolios, energy and healthcare operations.
- **Domain expertise:** Programmes spanning healthcare, robotics, defence, public sector and enterprise with human oversight built in.

**Strengths:** Backed by a long track record in training data and model evaluation.; End-to-end coverage from data sourcing through to deployed systems.; Experienced with regulated, classified and safety-critical environments.; Benchmarks and leaderboards give an independent view of model capability.

**Limitations:** No public pricing or self-serve signup - you need a sales conversation to get started.; Enterprise-scale contracting and data operations require real internal commitment.; Overkill for small teams with modest data or evaluation needs.; Some projects involve sensitive government and defence work with strict compliance overhead.
