## Labelbox

Labelbox occupies an unusual position in the AI stack: it does not primarily sell a chatbot or a generator, it builds the environments and data that models learn from plus the agents that take over recurring engineering and research work. The homepage claim is direct — frontier AI labs train on Labelbox environments and expert data, while engineering and research teams hand their recurring backlog to agents running on Recursion. A recent Series E of more than $100 million signals a heavily funded bet on that thesis.,For enterprises, the newer half of the product is Recursion. Agents are triggered by real signals — a failing build, a PagerDuty alert, a new dependency release, a fresh model checkpoint, or a Monday morning schedule — and then work in the background until the job is done. The examples the company promotes are concrete deliverables rather than summaries: a tested pull request with a preview link, a postmortem draft in Confluence with every event sourced, an ablation table naming the changes that mattered, or a patch for each exposed service after a critical CVE. A grader agent scores each run, and the graded session leaves behind memories, notes and skills that the next session reads before it acts.,The original foundation remains the data business: labeling, annotation, curation and model evaluation supported by expert human reviewers, used for computer vision, NLP, supervised fine-tuning, RLHF and red teaming. In practice the two halves reinforce each other, since the environments that produce high-quality training data are the same environments where agents learn to do real work. Pricing is enterprise-style, routed through sales conversations and shaped by data volume and agent usage, with no public self-serve tier.

**Pricing & Plans:** Contact for pricing. Labelbox does not publish self-serve plans or public rate cards; its pricing route instead directs interested teams to talk to sales, and cost is shaped by data production scope, agent deployment and enterprise requirements. There is no published free tier. Prospective customers should request a quote based on their volumes and use cases.

- **Data labeling and expert annotation:** Structured annotation, curation, model evaluation and human-in-the-loop review across vision, language and generative tasks, used to build the training and eval data behind production models.
- **Autonomous agent sessions:** Recursion agents start on their own from builds, alerts, commits, checkpoints and schedules, then work in the background until the task is finished and reviewable.
- **Domain specialists by function:** Specialist agents cover software engineering, reliability, security, ML research, evals, R&D, product and finance workflows, from flaky test fixes to postmortem drafts and vulnerability patches.
- **Graded outcomes that compound:** Every agent run is scored by a grader, and graded sessions leave memories, notes and skills that the next session reads before acting, so quality compounds over time.
- **Native tool and data integrations:** Agents operate against the tools teams already use, including GitHub, Jira, Linear, Slack, Datadog, PagerDuty, BigQuery, Databricks, Vercel and cloud providers.

**Strengths:** Covers both sides of the problem: training and eval data production plus agents that act on recurring work; Backed by a recent $100M+ Series E and adoption by frontier AI labs, indicating real funding and demand; Agent runs produce concrete deliverables with proof — tests, reruns, ablations — rather than unverified suggestions; Integrates with the toolchain teams already run: GitHub, Jira, Linear, Slack, Datadog, PagerDuty, BigQuery and Databricks

**Limitations:** No self-serve pricing or open signup: everything routes through a sales conversation, which slows down evaluation; The platform assumes real engineering and research infrastructure (GitHub, cloud providers, data warehouses) to deliver value; Positioning has shifted quickly toward autonomous agent sessions, so teams wanting only labeling workflows may find it heavier than needed

## Semafind

Semafind works with organisations that face problems too specific to be solved by off-the-shelf software. The firm positions itself between academic research and applied engineering: it helps clients explore whether a novel algorithm or model can create a competitive edge, builds a working prototype, then integrates that technology into existing infrastructure with training and ongoing support. Its stated process runs through ideation, prototyping and integration, each stage aimed at reducing the risk of research-heavy projects.

The consultancy publishes a portfolio of applied projects that show the range of work it takes on, including a visual spare-part identification system for engineering maintenance, semantic CV matching that recommends roles from resumes and job descriptions, AI networking recommendations for events, behavioural anomaly detection for early disease identification in animals, a reverse dictionary for company terminology, and personalised e-commerce product recommendations.

Semafind also productises some of this research. SemaReader focuses on semantic reading and automatic knowledge-graph creation from documents, while SemaDB is its vector database offering for similarity search. Knotes is an additional knowledge tool. The company is a UK-registered limited company and invites prospective clients to a free initial consultation. Because engagements are scoped per project, pricing is quoted on contact rather than published as fixed public tiers.

**Pricing & Plans:** Pricing is quote-based: Semafind offers a free initial consultation and scopes consulting engagements per project. Its software products such as SemaReader and SemaDB have their own plans — check the official site for current figures.

- **Custom AI & ML engineering:** Bespoke algorithms and models built for problems that generic tools cannot solve, from computer vision to recommendation systems.
- **Research-to-production pipeline:** A structured ideation, prototype and integration process designed to de-risk research-heavy projects before full rollout.
- **Semantic knowledge tooling:** Products including SemaReader for semantic reading and knowledge-graph creation, and SemaDB, a vector database for similarity search.
- **Data science consulting:** Hands-on data analysis, anomaly detection and predictive modelling engagements shaped around specific business goals.
- **Training and ongoing support:** Integration includes team training and continued support so new technology is adopted rather than shelved.

**Strengths:** Genuine research depth rather than template implementation; Clearly documented portfolio of applied projects across industries; Combines consulting with owned products such as SemaReader and SemaDB; Free initial consultation lowers the barrier to starting a conversation

**Limitations:** No published price list, so budgeting requires a sales conversation; Project-based engagements may not suit very small, low-budget teams; Product documentation for SemaReader and SemaDB is comparatively light
