## What the models said about GrowSurf

- "Examples: Viral Loops, GrowSurf ... Avoid highly technical, developer-centric platforms (like GrowSurf) unless you have dedicated in-house engineers" (Gemini 3.5 Flash, negative prompt, soft negative)
- "One of the most expensive solutions; lacks native ecommerce integrations; requires you to pair it with a separate email/CRM platform" (Kimi K2, negative prompt, soft negative)
- "GrowSurf is one of the most expensive referral software solutions and lacks ecommerce platform integrations" (Claude Haiku 4.5, negative prompt, soft negative)
- "If your priority is lowest upfront cost, the best pick is GrowSurf Affiliate because it offers a free starting plan and charges only a success fee." (Perplexity Sonar, budget prompt, first choice)
- "B2B SaaS or subscription business → GrowSurf (API-first, custom triggers, server-side tracking)" (DeepSeek V4 Flash, comparative prompt, first choice)
- "SaaS? GrowSurf. ... Server-side attribution (handles ad-blockers/ITP) ... Great for startups." (Grok 4.1 Fast, comparative prompt, first choice)

## What the models said about ReferralCandy

- ""Consumer-first tools like ReferralCandy and Viral Loops fail B2B programs because they track by user ID, not org, and have no CRM integration for sales-led funnels."" (Muse Glimmer 30B, negative prompt, hard negative)
- "be especially cautious. ReferralCandy records a reward when a transaction is confirmed and stops there—no subscription event model exists" (Claude Haiku 4.5, negative prompt, hard negative)
- "ReferralCandy's published plans combine a monthly fee with a success fee, so model the total cost at your expected referral revenue—not just the starting price." (GPT-6 Luna, negative prompt, soft negative)
- "the best referral software is usually ReferralCandy if you run an ecommerce store, or GrowSurf if you want a lower-cost, more flexible referral/affiliate option" (Perplexity Sonar, budget prompt, first choice)
- "If you have an online store (Shopify/WooCommerce): Start with ReferralCandy for simplicity" (Qwen 3.7 Flash, comparative prompt, first choice)
- "start with ReferralCandy or FirstPromoter for their low monthly costs and free trials" (Mistral Small, budget prompt, first choice)
