## Prolific

Prolific operates a marketplace where researchers and organisations post studies and verified participants complete them for payment. The pitch is quality over volume: instead of a massive but unvetted panel, Prolific verifies participants, applies attention and honesty checks, and lets requesters filter by detailed demographic, professional, and behavioural criteria. That makes it possible to target narrow, representative groups — for example coding experts, healthcare professionals, or specific national populations — which matters when a study compares groups or needs to generalise beyond a convenience sample.

In recent years Prolific has leaned heavily into AI. Its AI offering covers human preference data for fine-tuning and reinforcement learning, safety evaluation, red-teaming, and benchmarks across languages and tasks. It also publishes a leaderboard of model quality based on human evaluation, and offers developer-facing tooling such as a human-feedback API, agent workflows, and a Model Context Protocol server so AI pipelines can call for human input programmatically. Alongside this, the original academic and market-research business remains central.

Pricing is usage-based. Requesters pay for participant rewards plus a platform fee, and researchers either fund studies per response or talk to sales for larger programmes and managed services. Because rates depend on study length, targeting criteria, and volumes, published list prices are rare — the platform directs larger customers to a sales conversation.

**Pricing & Plans:** Usage-based for requesters: you pay participant rewards plus a platform fee, with custom quotes for large or managed programmes. Participants earn per completed study; joining is free.

- **Verified, targetable participant pool:** Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
- **AI data and human feedback:** Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
- **Built-in data-quality controls:** Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
- **Fast study launches:** Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
- **Participant side with guaranteed pay:** Participants get a clear per-study reward, flexible scheduling, and a minimum pay standard enforced by the platform.

**Strengths:** Strong focus on data quality with verification and attention checks; Granular targeting that supports niche and representative samples; Fast turnaround compared with traditional panel providers; Growing AI-focused tooling including a human-feedback API and MCP server

**Limitations:** Pricing is quote-based for many use cases, which makes budgeting less transparent up front; Participant availability in some narrow demographics can be limited or slower to fill; Costs add up quickly for large multi-country or longitudinal studies

## Urbalytics

Urbalytics is aimed at people who make money decisions about Japanese property: individual investors, brokers and owners. Its central premise is that the visible asking price hides most of what matters, so the platform assembles and visualizes the record behind a listing — every price revision, relisting, withdrawn listing and recorded sale, plus how the current price sits against comparable deals nearby. The site reports roughly 5.77 million tracked properties and over 19.8 million sale and price-history records, and it currently covers the four prefectures of the greater Tokyo area.

Functionally the product splits into free and paid layers. Free includes sale-history search, an undervaluation checker that scores a property against past transactions for its area and type, a self-service price estimate that accepts a listing URL, manual entry or photos and requires no sales follow-up, a 30-year cash flow and IRR simulation, an investment map of average yields by area, and favourite-property watching with alerts for price changes and relistings. The paid Plus tier adds neighbouring sale history, price-change and completed-deal records, market rent versus actual rent upside analysis, rental appraisal and undervaluation amounts.

An unusual feature of the platform is its editorial layer. Urbalytics publishes market reports broken down by developer brand, municipality, station and postcode, plus a 'price cut watch' section that aggregates the median reduction for apartments, single buildings, houses and land, alongside a blog with market analysis. The company is explicit that it is not an investment advisory or financial instrument sales service — the information is presented as reference material for the user's own judgement.

**Pricing & Plans:** Freemium. A free plan covers sale-history search, the undervaluation checker, self-service price valuation, cash flow simulation, the investment map and property watching. The Plus plan adds neighbouring sale history, price-change and closed-deal history, rent upside analysis and rental appraisal, listed at ¥4,167 per month on annual billing or ¥9,800 per month monthly, with a 7-day free trial that auto-converts to paid. A Pro tier for heavier professional use is quote-based via contact. Prices are as shown on the site and should be confirmed before purchase.

- **Price revision and sale history:** See a property's full timeline of listings, price cuts, relistings and recorded sales, including how many times the price moved and by how much.
- **Undervaluation checker:** A proprietary model benchmarks a property against past transactions for its area and property type, returning an undervaluation percentage and an amount in yen.
- **Self-service price and rent appraisal:** Submit a listing URL, manual details or photos to get an estimate in about a minute, with no sales calls and no obligation.
- **Cash flow and IRR simulation:** Enter price, income, taxes, repairs, loan repayments and equity to project net cash flow and IRR across 30 years in chart form.
- **Area reports and price-cut watch:** Market reports by brand, municipality, station and postcode, plus aggregated median price reductions by property type for the covered region.

**Strengths:** Price-revision and sale history is assembled in one screen rather than pieced together from portals; Several genuinely useful tools, including valuation and cash flow simulation, are free; Data coverage spans more than a decade, with market reports by station, area and postcode; Clearly states it is a data platform and not investment advice, avoiding overstated claims

**Limitations:** Coverage is limited to the greater Tokyo area (Tokyo, Kanagawa, Saitama and Chiba) so far, with other regions promised later; The most valuable history and rent-upside features sit behind the paid Plus plan and a trial that auto-converts to billing; Pro pricing is quote-only, making it hard to budget without contacting the company; Valuation figures are explicitly indicative and cannot account for daylight, interior condition or building management quality
