## AltIndex

AltIndex is an investment research platform built around alternative data — the non-traditional signals that hedge funds and quant desks have long paid heavily for. Instead of relying only on earnings and price history, it continuously measures things like company web traffic, app download estimates, job-posting momentum, Reddit and social chatter, insider transactions and congressional disclosures, then aggregates them into a single 0–100 score per stock.

Those scores feed several tools. Autopilot turns rules-based portfolios into models you can follow automatically; AI Stock Picks surfaces high-conviction long and short candidates drawn from the scoring model; and Stock Alerts push a notification the moment a company you care about spikes in popularity, sentiment or insider activity. A portfolio AI score lets you upload a screenshot of your brokerage and see every holding ranked, making it easy to spot the positions dragging your overall score below 60.

There is also an AI analyst interface that answers plain-English questions about your holdings, grounded in live AltIndex data rather than invented figures, and an MCP server plus API so institutions and developers can pipe the same signals into their own tools. The site also publishes free trending pages — Reddit stocks, congress trading, the Fear & Greed index, earnings calendar — and a regular newsletter with picks and market commentary.

**Pricing & Plans:** Freemium with a free tier and free trial. Searching tickers requires no account, and there is a newsletter promotion offering a discount. Paid plans unlock the fuller Autopilot, AI picks, alerts and institutional/API access; exact tiers are listed on the AltIndex pricing page.

- **Alternative-data signal engine:** Scores stocks using web traffic, app downloads, job postings, social mentions and insider activity rather than price charts alone.
- **AI stock picks and alerts:** High-conviction buy and sell signals plus real-time notifications when a holding spikes in popularity, sentiment or insider trading.
- **Portfolio AI score:** Upload a brokerage screenshot and get a 0–100 score for every holding, blended into a single portfolio score.
- **Ask AltIndex AI:** Ask plain-English questions about your holdings and get answers grounded in live scores, fundamentals and alt-data signals.
- **MCP server and API:** Plug AltIndex data into your own AI assistants, notebooks and internal tools for institutional or personal workflows.

**Strengths:** Blends genuinely differentiated alternative-data signals with standard fundamentals instead of repackaging price data; Portfolio scoring via a brokerage screenshot avoids any account linking or credential sharing; Publishes an MCP server and API, which is rare for retail-focused research platforms; A substantial library of free research pages and a newsletter make it easy to evaluate before paying

**Limitations:** AI stock picks come with no guarantee of future performance; the site cites a 61% win rate that is historical only; Some of the headline features, including Autopilot and institutional data access, sit behind paid plans; Alternative-data signals can be noisy and occasionally contradict the underlying fundamentals

## 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
