## Deferred

Deferred positions itself as the "no fee" 1031 exchange provider. A 1031 exchange lets a real estate investor defer capital gains tax by reinvesting the proceeds of a sold investment property into a replacement property, but the law requires a neutral Qualified Intermediary to hold the money in between. Most QIs charge a fee (often $1,000–$1,500 or more) and keep any interest the funds earn. Deferred flips that: it charges nothing on a standard forward exchange and passes a share of the interest back to the client.

The company says it has completed more than 8,000 exchanges and holds client funds at commercial bank partners in segregated, individually FDIC-insured accounts, with coverage options up to $175M plus a $25M fidelity bond and $5M errors-and-omissions policy. A team with over 200 years of collective 1031 experience handles the paperwork, deadlines and identification forms.

Pricing is transparent and exchange-type dependent: standard forward exchanges are free with interest sharing, while reverse exchanges start around $7,000 and improvement (build-to-suit) exchanges start around $7,500 because of their added complexity. The site advertises a perfect 5-star record on Google and Trustpilot.

**Pricing & Plans:** Standard forward exchanges are free with interest sharing; reverse exchanges start around $7,000 and improvement exchanges from about $7,500. Reverse and improvement exchanges are quoted individually.

- **No-fee forward exchange:** Deferred charges $0 on standard forward 1031 exchanges and instead earns from the interest generated by escrowed proceeds.
- **Interest sharing:** Unlike most QIs that keep the interest, Deferred pays a share of the interest earned on your exchange funds back to you.
- **Secured, segregated funds:** Proceeds are held in individually FDIC-insured accounts at commercial banks, with a $25M fidelity bond, $5M E&O cover and coverage options up to $175M.
- **All exchange types:** Supports standard forward exchanges plus more complex reverse and improvement (build-to-suit) structures with dedicated support.
- **Expertise and guidance:** A team with 200+ years of collective 1031 experience guides deadlines, 45-day identification and paperwork.

**Strengths:** No fee on standard forward exchanges; You keep a share of the interest your funds earn; Funds held in segregated, FDIC-insured accounts with high coverage limits; Advertises a perfect 5-star review record on Google and Trustpilot

**Limitations:** Reverse and improvement exchanges carry substantial fees (thousands of dollars); Interest-sharing economics depend on prevailing rates and hold duration; Services are US-specific and tied to IRS 1031 rules

## 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
