Everflow vs FirstPromoter

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.

FirstPromoter is affiliate and referral management software built specifically for SaaS and other subscription businesses. Its main job is to attribute signups and payments to affiliates or referring customers and calculate recurring commissions correctly over the life of a subscription, including upgrades, downgrades, refunds and cancellations.

It integrates directly with billing systems such as Stripe, Paddle, Chargebee, Recurly and Braintree, and offers a JavaScript tracking script and API for custom setups. Program managers can run several campaigns with different commission rules, tiered and multi-level rewards, coupons tied to affiliates, fraud detection for self-referrals and suspicious traffic, branded affiliate portals and payout management via PayPal or bulk files. Plans are priced by the referral revenue tracked each month, so cost grows with program success, and some extras cost more.

FirstPromoter suits subscription companies whose billing is not only Stripe or that need nuanced commission logic. It does not give you a marketplace of affiliates to recruit from, so you bring your own partners. Rewardful is simpler and popular with Stripe-only startups, Tolt is a newer low-cost option, and PartnerStack or Impact fit larger partner ecosystems with discovery and enterprise contracts. The interface is functional rather than modern, but tracking depth is the reason teams choose it.
