## AlterMe

AlterMe starts with a DNA test that maps genetic markers linked to how your body responds to exercise, nutrition and recovery. That genetic blueprint is then combined with continuous biometric signals — activity, sleep and readiness data — to produce a plan you actually follow, rather than a generic template.

The system delivers one unified plan across four pillars: fitness, nutrition, sleep and recovery. Plans are built and refreshed every week based on your goals (weight loss, strength, longevity or thriving on GLP-1 medications) and your recent data, so the guidance adapts as your body and habits change.

The company markets itself on outcomes rather than features, citing member surveys around weight loss, fitness gains and visceral fat reduction, and positions the product as HSA/FSA eligible. AlterMe is designed for people who have tried generic programs and want a plan grounded in their own biology.

**Pricing & Plans:** Paid. Entry point from $49 to start, with financing options available, plus a DNA test that is regularly discounted from around $99.

- **DNA Blueprint:** A saliva DNA test maps genetics related to fitness response, nutrition and recovery, producing an actionable blueprint rather than a raw report.
- **Biometric tracking:** Connects wearable sensor data to track activity, sleep and daily readiness, feeding those signals back into your weekly plan.
- **Adaptive weekly plan:** Your exercise, nutrition and recovery plan is rebuilt each week from your goals and latest biometric data so it never goes stale.
- **Multi-goal programs:** Choose a focus such as losing weight, building strength, increasing longevity or supporting GLP-1 treatment, and the plan adjusts accordingly.
- **All-in-one wellness system:** Fitness, nutrition, sleep and recovery live in a single app instead of being spread across multiple subscriptions and programs.

**Strengths:** Personalization driven by DNA plus live biometric data, not a static questionnaire; A single system covering fitness, nutrition, sleep and recovery; HSA/FSA eligible and priced to start at a low entry point; Weekly plan refresh keeps guidance relevant as goals change

**Limitations:** Requires completing a DNA test before the full system kicks in; Some outcome statistics come from member surveys rather than independent trials; Ongoing subscription plus test cost adds up over a year

## 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
