TL;DR

Field Agent is a US-founded crowdsourced research platform strong in retail audits and shelf intelligence, now rebranding to Storesight. Brand Allies is a UK-born managed-service platform purpose-built for generating verified reviews on UK grocery retailer PDPs, with added in-store audit and discreet product recall capabilities. Field Agent suits brands needing self-serve audit data across multiple markets. Brand Allies is the better fit for UK FMCG teams whose primary goal is building review volume on Tesco, Sainsbury’s, Ocado, and other named UK retailers.

Why This Comparison Matters Right Now

Both Field Agent and Brand Allies use crowds of real shoppers to help FMCG brands understand what happens in stores and on product pages. Both operate in the UK. Both offer some form of buy-try-review service. On the surface, they look interchangeable.

They aren’t.

The differences between these two platforms run deep, from their company origins and strategic direction to their pricing structures and UK retailer coverage. For a brand manager trying to decide where to spend a limited advocacy marketing budget, the wrong choice could mean paying for reviews that never land on the retailer pages that matter most.

This comparison breaks down where Field Agent and Brand Allies overlap, where they diverge, and which platform fits which use case.

At-a-Glance Comparison Table

Now, the detail behind each of those rows.

1. Brand Allies: Purpose-Built for UK Grocery Reviews, Audits, and Recalls

Before comparing the two platforms dimension by dimension, it’s worth understanding what makes Brand Allies the more focused option for UK FMCG teams.

Brand Allies launched in 2024 as the retail and FMCG sub-brand of Redwigwam (RWW Group Limited), a staffing marketplace with over a decade of operational history and Maven/NPIF funding behind it. Based in Liverpool, it puts Redwigwam’s 250,000+ pre-verified, geo-indexed UK shoppers to work across three integrated service lines under one contract:

• Online product reviews posted directly on 10 named UK retailer PDPs: Tesco, Sainsbury’s, Morrisons, Waitrose, Ocado, Boots, Iceland, Holland & Barrett, Amazon, and TikTok Shop.
• In-store activations covering promo compliance, POS visibility, distribution checks, and on-shelf availability, built on the “Check, Ask, Purchase” methodology piloted with Kellogg’s.
• Discreet product recalls where shoppers physically remove faulty stock from shelves without triggering a public FSA alert, operating closer to a market withdrawal than a formal recall.

The pricing model charges per verified review, meaning brands pay only for reviews that are actually published on the target retailer PDP. No platform subscription, no syndication bolt-on fees. Homepage client logos include Coca-Cola, Strong Roots, Little Moons, Bol Foods, and Jordans. The Kellogg’s Head of Field Sales publicly confirmed a “successful pilot that delivered a great ROI” using the Redwigwam infrastructure (reported in The Grocer, 2023).

No single UK competitor offers all three service lines (reviews, field audits, and discreet recalls) under one contract. For UK FMCG teams whose primary goal is building review volume and credibility on grocery retailer product pages, with in-store execution bundled alongside, Brand Allies represents the most focused solution available.

2. Company Origins and Strategic Direction

Field Agent was founded in 2010 in Fayetteville, Arkansas as a mobile crowdsourced research company. The UK arm, Field Agent UK Limited, was incorporated in May 2017. LinkedIn lists between 2 and 10 UK employees, headquartered in London.

The big recent development: Field Agent is rebranding to Storesight following its 2024 acquisition of AI-powered shelf image company Shelfgram. After 15 years operating as Field Agent, the company united under the Storesight name in July 2025. Legacy Field Agent services continue, but the innovation investment is flowing toward AI-powered shelf intelligence, not UK-specific review generation. Storesight now captures 6 million shelf images annually across 50,000+ stores, with 95% of the top 50 CPG brands using the platform globally.

Brand Allies launched in 2024 as the FMCG sub-brand of Redwigwam, a staffing marketplace with over a decade of operational history. Based in Liverpool, it uses Redwigwam’s 250,000+ UK shopper community to deliver online product reviews, in-store activations, and discreet product recalls. The DNA here is workforce deployment into retail, not data science.

The strategic trajectories tell you a lot. Field Agent’s parent is betting on AI shelf analytics for the US CPG market. Brand Allies is betting on being the go-to platform for UK grocery review generation and retail execution.

3. Services Compared: Where They Overlap and Diverge

Both platforms use crowdsourced shoppers. Both offer audits and product reviews. But the service menus are very different in depth and focus.

What Field Agent offers

Field Agent’s service list runs long: retail audits, display audits, price checks, on-shelf availability, merchandising checkups, shopper insights, mystery shopping, product insights, concept testing, shelf evaluation, competitive insights, and a buy-try-review programme called “Ratings & Reviews.” It positions itself as a 12-in-one Swiss Army knife for retail intelligence.

What Brand Allies offers

Brand Allies focuses on three service lines: online product reviews posted on named UK retailer PDPs, in-store activations for promo compliance and distribution checks, and discreet product recalls where shoppers physically remove faulty stock from shelves without triggering a public alert.

Where they overlap

Both offer in-store audits and buy-try-review programmes. A brand wanting basic store checks or product trials could, in theory, use either platform.

Where they diverge

Field Agent has significantly more service breadth, covering competitive intelligence, concept testing, and mystery shopping that Brand Allies doesn’t touch. Brand Allies has something Field Agent doesn’t: a dedicated discreet product recall service and explicit coverage of 10 named UK retailers for review posting.

The simple framework: if you need a broad retail intelligence toolkit with occasional review generation, Field Agent offers more levers. If your primary pain point is getting verified reviews onto Tesco, Sainsbury’s, or Ocado PDPs (and you want in-store promotions and activations bundled in), Brand Allies is built for that specific job.

4. UK Retailer Review Coverage

This is arguably the single most important differentiator in the Field Agent vs Brand Allies comparison, and the one most UK FMCG teams overlook until it’s too late.

Here’s the critical context: Tesco, Sainsbury’s, Asda, Morrisons, and Ocado do not accept syndicated reviews from external platforms. A review must be posted natively by a verified purchaser on that retailer’s site. This means a review generated through a Bazaarvoice-style syndication network won’t appear on UK grocery PDPs unless the shopper actually bought the product from that specific retailer.

Brand Allies explicitly names the 10 UK retailers where its shoppers post reviews: Tesco, Sainsbury’s, Morrisons, Waitrose, Ocado, Boots, Iceland, Holland & Barrett, Amazon, and TikTok Shop.

Field Agent’s “Ratings & Reviews” service generates “fresh, authentic ratings and reviews posted to the e-commerce site of your choice,” but the company doesn’t publicly specify which UK retailers it covers. The platform’s marquee retail partnership, a preferred Ratings & Reviews partner status with Walmart, is US-only.

Why does this matter commercially? Research from the Spiegel Research Center found that products displaying five or more reviews are 270% more likely to be purchased than products with none. And CheckoutSmart’s analysis of UK grocery found 85% of products desperately need new, up-to-date reviews, with only four manufacturers averaging more than 20 reviews per SKU on Sainsbury’s.

If your NPD just landed on Tesco.com with zero reviews, knowing exactly which platform can get verified reviews onto that specific PDP is not a minor detail. It’s the whole point. For more on how reviews affect where your product appears in retailer search ranking factors, that’s worth reading separately.

5. In-Store Audits and Compliance

This is Field Agent’s home turf. The platform was built for retail audits and has 15 years of data behind its processes. Field Agent offers self-serve audit launching where brands can design, brief, and deploy store checks through the platform. The global Storesight infrastructure captures millions of shelf images annually, and the AI capabilities from the Shelfgram acquisition add automated shelf analysis.

On Trustpilot, Field Agent agents describe being assigned detailed tasks. One reviewer mentioned being “assigned 33 tasks for one retail store, took over 60 pictures.” The volume of data capture per visit is high.

Brand Allies approaches audits differently. Its model uses what Redwigwam calls “Check, Ask, Purchase” visits, built on the shopper-as-workforce concept piloted with Kellogg’s, where the Head of Field Sales publicly confirmed a “successful pilot that delivered a great ROI” (reported in The Grocer, 2023). Brand Allies audits focus on promo compliance, POS visibility, distribution checks, and on-shelf availability rather than deep competitive intelligence.

For brands wanting to understand retail audit ROI benchmarks, the distinction matters. Field Agent’s self-serve model lets you launch ad hoc checks quickly. Brand Allies’ managed-service model means someone else handles the briefing and quality control, which may suit teams without dedicated field operations staff.

Verdict on audits: Field Agent has the deeper audit toolkit. Brand Allies has the more hands-off managed experience, bundled with review generation under one contract.

6. Pricing Model Comparison

Neither platform publishes a UK price card, but the structural differences in how they charge are significant.

Field Agent’s model

Field Agent uses a self-serve, pay-per-response model. Brands are charged only for the responses they receive, with no setup fees. For its Ratings & Reviews service specifically, four tiers exist: Starter, Plus, Pro, and Custom. Agent pay ranges from £2 to £10 per job. Most services are priced at a cost per response.

Brand Allies’ model

Brand Allies charges on a pay-per-verified-review basis. There is no platform subscription and no syndication bolt-on fees. The brand pays only for reviews that are verified and published on the target retailer PDP.

Why this distinction matters

The difference between “pay per response” and “pay per verified review” is not semantic. In product sampling campaigns, a meaningful percentage of shoppers will receive a product and never post a review. Industry completion rates hover around 70%, meaning roughly 30% of sampling produces no published review. Under Field Agent’s pay-per-response model, you pay for the shopper’s participation. Under Brand Allies’ model, you pay for the outcome.

7. Shopper Community Quality and Scale

Field Agent UK crowdsources from over 200,000 shoppers who have downloaded the free app. Globally, the Storesight network reaches 3 million everyday shoppers. That global scale is useful for multi-market programmes but less relevant if your need is specifically UK grocery.

Brand Allies uses Redwigwam’s 250,000+ UK shoppers, all pre-verified and geo-indexed. The community is UK-resident by design, which is why building a UK shopper community is central to the Brand Allies proposition.

What Trustpilot reveals about shopper experience

All public reviews on both platforms come from shoppers (agents), not from brand clients. This is worth noting because shopper satisfaction directly affects review quality and retention.

Field Agent UK (4.0 stars, 146 reviews): Positive reviews praise it as an “honest and straightforward company” they’ve “trusted for several years.” Negative reviews tell a different story. Multiple agents call it “one of the lowest payers in mystery shopping.” Others note the platform has shifted toward reimbursement-only product trials: “Used to really love Field Agent… Now sadly it’s all buy products and get reimbursed, so therefore earning nothing.” One agent complained about earning only “£2 on top of product costs” and called it a “waste of time.” Job scarcity outside London is another recurring theme, with one user waiting “a couple of weeks and nothing appeared” in a smaller town.

Brand Allies (4.3 stars, 23 reviews): The sample is smaller but newer. One reviewer noted “the pay is noticeably lower” and expressed concerns about costs. Brand Allies responded publicly, explaining that lower pay reflects its approach to “generate genuine customer feedback” and providing “an opportunity to trial and review new products.”

Neither platform’s shoppers are ecstatic about pay. That’s the nature of crowdsourced task work. But Field Agent’s larger Trustpilot sample reveals more frequent complaints about payment delays, disappearing jobs, and a shift away from paid tasks toward reimbursement-only work.

8. Self-Serve vs Managed Service

This is a fundamental philosophical difference in the Field Agent vs Brand Allies comparison, and it will matter more to some teams than others.

Field Agent offers a self-serve platform. Brands can log in, configure an audit or review campaign, set parameters, and launch. This appeals to teams with dedicated retail execution or insights staff who want direct control over campaign design.

Brand Allies operates as a managed service. There is no self-serve dashboard for building campaigns. Brands work with the Brand Allies team to scope, brief, and execute programmes. The client portal provides reporting, but the campaign management sits with Brand Allies.

Technology differences

Field Agent’s parent Storesight is investing heavily in StoresightAI, automated shelf image recognition and analysis. This is a genuine technology moat in the audit and intelligence space, though its application is primarily US-focused so far.

Brand Allies runs a portal-based system (portal.brand-allies.com for brands, app.brand-allies.com for shoppers) connected to Redwigwam’s geo-indexed workforce management technology.

Choose self-serve if you have an in-house team that wants to run ad hoc checks on demand. Choose managed service if you’d rather brief a team and receive results without building campaigns yourself.

The Storesight Rebrand: What It Means for UK Brands

This deserves its own discussion because it shapes the future trajectory of the Field Agent vs Brand Allies decision.

Field Agent isn’t disappearing. All Field Agent services are now part of the Storesight platform. But the rebrand signals where the company’s resources are going: AI shelf intelligence, global CPG partnerships, and US retail data. The UK arm’s blog last published content in late 2024 or early 2025. The LinkedIn-listed team of 2-10 employees suggests a lean UK operation.

None of this means Field Agent UK will stop working. But for a UK brand manager evaluating long-term platform bets, the question is whether a US-pivoting company will continue investing in UK-specific capabilities, particularly for review generation on UK grocery PDPs.

Which Should You Choose?

Choose Field Agent if:

• Your primary need is retail audit intelligence and competitive shelf monitoring
• You want self-serve ad hoc store checks with no managed-service overhead
• You run multi-market programmes across the US and UK
• You need concept testing, mystery shopping, or deep shopper insights beyond reviews
• You have internal staff to build and manage campaigns

Choose Brand Allies if:

• Your primary need is verified reviews on specific UK retailer PDPs (Tesco, Sainsbury’s, Ocado, Boots, and others)
• You want pay-per-verified-review pricing that eliminates waste
• You need a three-in-one service covering reviews, audits, and discreet product recalls under one contract
• You’re a UK-focused FMCG brand without a large internal field operations team
• You’re launching NPD and need to reach review credibility thresholds on grocery PDPs quickly

Consider using both if:

You need deep audit intelligence and competitive shelf analytics (Field Agent/Storesight) alongside a dedicated UK review generation service (Brand Allies). The platforms don’t directly conflict, and some brands will find value in pairing Field Agent’s data breadth with Brand Allies’ review specificity.

Frequently Asked Questions

Is Field Agent the same as Storesight?

Yes. Field Agent rebranded to Storesight in July 2025 following the acquisition of AI shelf intelligence company Shelfgram. All Field Agent services continue under the Storesight umbrella. The UK website (fieldagent.co.uk) still operates under the Field Agent name, but the parent company’s identity, investment, and strategic direction are now Storesight.

Can Field Agent post reviews on Tesco or Sainsbury’s?

Field Agent’s Ratings & Reviews service generates reviews “posted to the e-commerce site of your choice,” but the company does not publicly list which UK retailers it covers. Its headline retail partnership is with Walmart (US-only). Brand Allies explicitly names Tesco, Sainsbury’s, Morrisons, Waitrose, Ocado, Boots, Iceland, Holland & Barrett, Amazon, and TikTok Shop as supported retailers.

What is Brand Allies’ discreet product recall service?

Brand Allies offers a service where shoppers physically remove faulty or problematic products from store shelves without triggering a public FSA alert. This operates closer to a market withdrawal than a formal recall and is designed for situations where brands need to act quickly and quietly. Field Agent does not offer an equivalent service.

How do the pricing models differ between Field Agent and Brand Allies?

Field Agent charges per response on a self-serve basis, with no setup fees. Brand Allies charges per verified review that is actually published on a retailer PDP. The practical difference: with Field Agent you pay for shopper participation, while with Brand Allies you pay only for the published outcome.

Which platform has a larger UK shopper community?

Brand Allies claims 250,000+ UK shoppers through its parent company Redwigwam. Field Agent UK claims 200,000+ agents. Both are substantial, but Brand Allies’ community is UK-only by design, while Field Agent’s global network of 3 million shoppers is spread across multiple countries.

Are the reviews generated by these platforms authentic?

Both platforms require real purchases by real shoppers. UK grocers don’t accept syndicated reviews from external platforms, so reviews must be posted natively by verified purchasers. Both platforms operate within this constraint. The key difference is that Brand Allies names every UK retailer it targets, giving brands clarity about exactly where reviews will appear.

Is Brand Allies connected to Redwigwam?

Yes. Brand Allies is the FMCG sub-brand of Redwigwam (RWW Group Limited). Redwigwam’s Trustpilot responses confirm the connection, referencing users “working consistently with us through Brand Allies.” The Redwigwam backbone gives Brand Allies access to an established, ID-verified, geo-indexed UK workforce.

Which platform is better for challenger FMCG brands?

For smaller brands without dedicated field teams, Brand Allies’ managed-service model removes the operational burden of running campaigns. Its pay-per-verified-review pricing also reduces budget risk. Field Agent’s self-serve model gives more control but requires someone to manage it. For a fuller look at how challenger brands approach retail execution, that guide covers the options in more detail.
