## 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

## RFPG

RFPG lets investors, developers and tradespeople appraise a property by walking around it with a phone. Rather than a rough guess, the app produces an itemised refurbishment estimate broken down by room and trade, along with a materials list and schedule of works, and packages it all into a PDF deal pack.

The deal pack covers over 40 data points, including value estimates and sold-price comparables from HM Land Registry (England and Wales), the deal maths and a maximum offer figure, area average rent from ONS with gross yield, planning and flood checks, HMO and short-let routes, energy and safety items, and local crime, house-price and earnings data.

RFPG runs on any phone, with the most accurate scans coming from iPhone 12 Pro or later Pro models that have a LiDAR sensor and Android phones supporting ARCore Depth. Coverage varies by data source: refurbishment cost estimates span England, Wales, Scotland and Northern Ireland, while value estimates, Land Registry comparables and the EPC check cover England and Wales only. It also supports a social profile and an affiliate programme, and is built by a property developer turned software developer.

**Pricing & Plans:** RFPG uses a free app with paid reports. Your first scan is free, a single full report costs £29 (or 5 reports for £99), and subscription plans include Bronze (about £490/year, 3 reports a month), Silver (about £990/year, 10 reports a month) and Gold (about £2,490/year, 30 reports a month plus onboarding). Trades plans are priced per priced job — Trades Starter £390/year, Trades Standard £490/year and Trades Pro £790/year — and credit packs are available. A founding-member promotion running to 30 November 2026 takes 50% off year one of a yearly plan and 20% off renewals for life. Prices are shown in GBP and the company states it is not VAT registered.

**Strengths:** Turns an on-site walkthrough into an itemised costed deal pack; Pulls comparables and rent data from HM Land Registry and ONS; Works on any phone, with LiDAR-based accuracy on newer iPhones; Free first scan plus a single-report option if you do not want a plan

**Limitations:** Value estimates, Land Registry comparables and EPC checks only cover England and Wales; Outputs are estimates, not a RICS valuation or survey; Unused reports in a plan do not carry over between months
