## 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

## Runopt

Runopt is an AI-powered software platform for land development. It pairs interactive 3D zoning maps with logic-backed feasibility analysis so that developers, engineers, utilities, regulators and community stakeholders can evaluate sites together from the earliest stage. The goal is transparency: by surfacing zoning, terrain and utility data in a shared, data-driven view, Runopt aims to speed up approvals and reduce costly redesigns later in a project.

The platform has a strong focus on data centers, offering a collaborative surface where developers, utility providers and regulators align on power, connectivity and zoning requirements. It also includes government planning analysis that gathers the latest published municipal information and benchmarks it against neighboring jurisdictions to forecast future planning steps, plus a professional network for connecting with subject-matter experts. Broader capabilities cover residential, commercial, transportation and industrial sites, with rail and agriculture planned for later packages.

Runopt is currently onboarding via a waitlist. It emphasizes privacy and compliance, noting HTTPS encryption in transit, encrypted storage at rest, the option to delete uploaded data at any time, and help with local data storage for larger organizations. Its stated mission is to become a global leader in digital land development solutions.

**Pricing & Plans:** Runopt does not publish public pricing. The site invites visitors to join a waitlist and to contact the team, and it describes a tiered set of packages (with some use cases, such as rail and agriculture, planned for later packages). Pricing is therefore arranged directly with the vendor.

- **3D zoning maps with feasibility logic:** Interactive 3D zoning maps paired with logic-backed feasibility analysis let teams view zoning, terrain and utility constraints on a shared surface.
- **Site scoring and comparison:** Score, compare and export multiple sites to evaluate potential quickly and make data-driven investment and planning decisions.
- **Collaboration and data center site proposals:** A shared platform for developers, utilities and regulators to align on power, connectivity and zoning requirements early, improving transparency.
- **Government planning analysis:** Collects and analyzes published government planning information and benchmarks it against nearby municipalities to forecast future planning steps.
- **Compliance and productivity automation:** Automates repetitive calculations so teams can complete hundreds of site assessments per year faster, while keeping projects aligned with the latest zoning and regulatory requirements.

**Strengths:** Combines 3D visualization with logic-backed feasibility in one platform; Built for multi-stakeholder collaboration between developers, utilities and regulators; Automates repetitive site calculations to speed up assessments; Strong stated data-privacy posture with encryption and deletable uploads

**Limitations:** Still in a waitlist phase, so immediate access may be limited; Pricing is not published, requiring a sales conversation; Focused mainly on site feasibility and zoning rather than full design or construction documentation; Some use cases such as rail and agriculture are noted as later packages
