Everflow vs PromoteKit

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.

PromoteKit is affiliate management software for SaaS companies that bill through Stripe. It is built for indie hackers and small teams: you add one script tag to your site, connect your Stripe account, and PromoteKit tracks referral clicks, attributes signups and calculates commissions automatically from real Stripe payments, including recurring subscription revenue.

Affiliates get a branded portal where they sign up, grab links and coupon codes, and see clicks, conversions and earnings. Founders can set commission rates and durations, approve affiliates, track coupon-based referrals, and manage payouts from one dashboard, with webhooks for connecting other tools. Pricing takes no percentage of affiliate revenue: a free plan covers the first three referrals, a flat-priced Pro plan is among the cheapest in the category, and Enterprise is for larger programs.

PromoteKit fits early-stage and micro-SaaS products that want to start an affiliate program in an afternoon without a large budget. Because it is Stripe-focused and relatively new, teams on Paddle or other billing systems, or those running large programs with complex rules, will find it limited, and reporting is basic. Rewardful is the more established Stripe affiliate tool with deeper features, Tolt is a similar budget alternative, FirstPromoter suits growing SaaS programs, and PartnerStack or Impact serve larger partner ecosystems.
