Everflow vs GrowSurf

Everflow is a partner marketing and affiliate tracking platform based in Mountain View, California, founded in 2016 and preparing for its tenth anniversary in 2026. It serves brands, affiliate networks and agencies that pay partners for sales, leads or installs. Its core job is to track every click and conversion back to the right partner, pay them correctly and show which partners actually drive revenue. In December 2025 the company said it tracked $4.3 billion in partner revenue, up 19% year over year.

Everflow tracks repeat purchases, upsells and subscriptions, and can pay on later-stage events such as approved leads, SQLs or retained customers through HubSpot and Salesforce. Everflow Pay manages payouts, a Marketplace helps recruit affiliates, and traffic health monitoring flags blocked or broken tracking links. It also pulls spend from Google Ads, Facebook and TikTok for blended attribution, and it is API-first, with an MCP server for AI agents. Pricing is quote-only with a 6-month commitment, onboarding and free migration.

Everflow suits performance marketers and networks running serious affiliate volume who need flexible payout rules and server-side tracking. impact.com is the enterprise heavyweight for broader partnership types, PartnerStack focuses on B2B SaaS, and Tapfiliate or Post Affiliate Pro are cheaper self-serve tools for smaller programs.

Buying tip: there is no public price and the 6-month commitment applies, so prepare your monthly click, conversion and payout volumes before the sales call and ask which integrations and seats are included.

GrowSurf is a US-based referral and affiliate marketing platform built for tech startups and SaaS products. It gives every user a referral link automatically, tracks who referred whom, and pays out rewards, so a company can launch a customer referral program with one code snippet instead of building the logic in-house.

Core features include white-labeled referral portals, configurable qualification rules (signup, first purchase or custom events), automatic rewards as gift cards, cash or account credits, manual approval, fraud protection, analytics and tax form collection with 1099 filing. It offers native integrations such as Stripe, Chargebee, Recurly, Salesforce, PayPal and Wise, plus a REST API, JavaScript library, webhooks and an MCP server for AI coding tools. Referral programs are paid with a 14-day trial; affiliate programs run on a free plan with a 3% success fee.

GrowSurf fits B2B and B2C software companies with a few thousand active customers who want referrals embedded in the product. Ecommerce stores on Shopify are better served by ReferralCandy, waitlist and viral launch campaigns by Viral Loops, and Stripe-first affiliate programs by Rewardful or FirstPromoter, which start cheaper.

Buying tip: plans are priced by participants, not by referrals. Startup costs $179 a month for up to 2,500 participants ($125 billed yearly) and Business starts at $449 for 10,000, so only enroll users who are likely to share. If you mainly want affiliates, the free plan with the 3% fee avoids a fixed subscription.
