## 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

## Spatial.ai

Spatial.ai starts from a simple premise: two consumers with identical demographics can behave completely differently, so demographics alone are a weak basis for retail marketing and site selection. Its PersonaLive system classifies every U.S. household into 17 high-level groups and 80 behavioral segments derived from four dimensions of observed behavior — demographics, social media activity, mobile movement data, and credit card transactions. The company reports that this multi-source approach improves retail behavior prediction by an average of 17% and produces campaigns that perform up to 50% better.

The workflow runs in three steps. First, marketers identify their top segments in minutes by uploading CRM contact lists to see which segments are most valuable, or by uploading a visitation report — or simply drawing a polygon — to see which segments visit a location most. Second, they position the brand strategically using consumer spend data: comparing market share against competitors by segment and tracking how much each segment spends on different brands over time. Third, they build tailored multi-channel campaigns by viewing detailed segment portraits, personalizing ad imagery and copy, and exporting audiences to Meta, TikTok, Google, Snapchat, X, programmatic platforms, and direct mail.

Alongside PersonaLive, Spatial.ai offers Proximity for segmenting neighborhoods by social media behaviors and FollowGraph for quantifying consumer social interest at a geographic level. Typical applications include site selection, digital marketing, credit card market share analysis, and retention and expansion programs. The platform is used by more than 750 retailers, e-commerce brands, and agencies, and case studies cite clients including Colliers, HIFI Agency, AAA, SeaQuest, and Goodwill. Data is permissioned, anonymized, and aggregated, so the system describes behaviorally similar groups rather than identifying individuals.

**Pricing & Plans:** Paid subscription with three published tiers on monthly or annual billing. The Analyst is $500/month (or $425/month billed annually), The Media Buyer is $800/month (or $700/month annually), and The Strategist is $1,500/month (or $1,350/month annually). Contacts and locations are billed separately at the greater of the two counts, from $0 up to $500/month at unlimited scale. Each plan includes up to 5 users.

- **PersonaLive behavioral segments:** Every U.S. household is classified into 17 high-level groups and 80 behavioral segments built from demographics, social media activity, mobile movement data, and credit card transactions.
- **Segment your own data fast:** Upload CRM contact lists or a store visitation report, or draw a polygon, to see which segments drive the most value or visit a location most — typically in minutes.
- **Market share and spend analysis:** Compare your brand against competitors by segment and track how much each segment spends on different brands over time, using insights from 100M+ credit card transactions.
- **Cross-channel audience activation:** Export top segments for targeting across Meta, TikTok, Google, Snapchat, X, programmatic platforms, and direct mail, or enrich your CRM with demographic and segment codes.
- **Segment portraits and creative guidance:** Detailed segment portraits reveal which brands customers visit, who they follow on social, the best channels to reach them, and key demographic traits to guide ad imagery and copy.

**Strengths:** Behavioral segmentation combining social, mobile, and transaction data adds context that demographics alone miss; Self-serve segmentation from CRM files or visitation data delivers answers within minutes; Audiences export to every major ad channel plus direct mail from one platform; Transparent published pricing with 90-day opt-out and multiple case studies from real brands

**Limitations:** Coverage is limited to U.S. households, so non-U.S. brands are not served; Plans start at $500/month and contacts or locations are billed separately, which is steep for small retailers; Advanced competitive spend analysis requires the top Strategist tier
