## Intuition Machines

Intuition Machines is a research-driven AI/ML company best known for hCaptcha, an independent, privacy-first alternative to reCAPTCHA that protects a large share of the internet. Behind the CAPTCHA business sits a broader stack of machine-learning platforms used by payment processors, marketplaces and other high-traffic online services to separate legitimate users from automated abuse. The company also maintains an active research programme, including published work on weakly supervised OCR and on generative AI safety.

The product portfolio covers three areas. The hCaptcha security suite is the consumer-facing layer, deployed on websites and in apps. The IM Perception Platform gives engineering teams an API-driven way to train, deploy and continuously improve perception models with active learning rather than large labelled datasets. Risk Insights supplies scoped, blinded risk signals that enrich a customer's own models without exposing personally identifiable information, which matters for companies operating under GDPR and similar regimes.

Because its customers are large online services, Intuition Machines sells primarily through a sales-led enterprise process rather than self-service plans. hCaptcha is popular with smaller sites, but the enterprise modules, custom model training and risk-signal products are quoted individually. Teams evaluating it should expect to talk to sales and to review documentation rather than sign up instantly online.

**Pricing & Plans:** Pricing is not published for most products. hCaptcha has a widely used free tier for sites of varying sizes, while enterprise offerings such as hCaptcha Enterprise, the IM Perception Platform and Risk Insights are sold through contact-for-pricing arrangements.

- **hCaptcha security suite:** A privacy-first security AI suite used by websites and apps to block bots and abuse, positioned as an independent alternative to reCAPTCHA.
- **IM Perception Platform:** An active-learning platform with robust APIs that automates the full train, deploy and improve cycle for computer-vision models.
- **Risk Insights:** Scoped and blinded signals that enrich risk scoring while keeping ML models compliant with global privacy laws and free of PII.
- **Fraud and abuse detection ML:** Detection models for credential stuffing, account takeover, card testing, chargeback fraud, purchase fraud and SMS tolling fraud.
- **Continuous active learning:** Semi-supervised evolutionary strategies keep model accuracy stable as real-world data shifts over time.

**Strengths:** Operates at internet scale, protecting hundreds of millions of users; Privacy-first design avoids PII and helps with GDPR-style compliance; Combines a widely adopted product (hCaptcha) with serious published ML research; Covers multiple fraud types, from bot traffic to payment and card-testing abuse

**Limitations:** Enterprise-focused sales process, not self-serve sign-up; hCaptcha is free for basic use but enterprise features sit behind a sales conversation; Documentation and tools are aimed at engineering and security teams rather than casual users; Pricing details for the Perception Platform and Risk Insights are not published

## Roundtable (Proof of Human)

Roundtable began as an AI-powered fraud prevention platform and now operates under the name Proof of Human (Proof of Human, PBC). The roundtable.ai domain redirects to poh.org, and the site explicitly describes the company as formerly Roundtable AI, so the underlying product and team remain active — simply under a new brand and mission framing as a public benefit corporation.

The core of the product is an invisible verification API. Instead of asking users to solve puzzles, it watches how they interact with a page: how they type, where the mouse travels, how they scroll, whether they paste text or leave typos uncorrected, and how their clicks land. Those signals roll into a live behavioral profile that distinguishes real humans from scripts, bots and increasingly capable AI agents. Verification is continuous rather than a one-time gate.

Because the approach is behavioral rather than identity-based, the company emphasizes privacy: no PII is collected and no cross-site tracking is performed. Integration is a single script with a site key and user ID, and the platform reports millions of sessions processed each month with sub-200ms latency backed by SLA guarantees.

Use cases cluster around market research (verifying panel respondents), financial services (account creation and high-risk transactions), ticketing and live events (stopping scalper bots), and general fraud, bot and account takeover prevention. Pricing is quote-based and available by contacting sales or booking a demo.

**Pricing & Plans:** Roundtable (Proof of Human) does not publish public price tiers; pricing is quote-based and available on request. Prospective customers are directed to book a demo or email the sales team to discuss enterprise pricing and volume.

- **Invisible, Frictionless Verification:** Proof of Human runs silently behind login and checkout flows, scoring behavior in under 200 milliseconds without CAPTCHAs or friction for real people.
- **Continuous Behavioral AI:** Continuous behavioral models look for programmatic typing, teleporting mouse movement, jump scrolling, centered clicks and pasted text to catch bots and AI agents mid-session.
- **Privacy-Preserving by Design:** The service states it collects no PII and does no cross-site tracking, helping teams meet compliance and privacy requirements.
- **Effortless Integration:** A single script tag with a site key and user ID is enough to begin verifying sessions, and results include an example session report with explainable signals.
- **Enterprise-Scale Performance:** The platform reports millions of sessions processed monthly and near-instant API latency with SLA guarantees, suited to high-traffic consumer flows.

**Strengths:** No CAPTCHAs, popups or friction for genuine users; Continuous behavioral scoring rather than a one-time human check; Detects modern AI agents as well as classic bots; Privacy-preserving: no PII and no cross-site tracking

**Limitations:** Pricing is quote-based, so buyers cannot self-serve or compare costs upfront; Enterprise buyers must go through a demo and sales process; Continuous behavioral verification can raise privacy review questions before deployment; Previewed prices and plans are not published on the site
