Companies Using Rewardful

Affiliate software is a marketing decision before it is a technical one, so I wanted to see who buys Rewardful. Our October 2026 crawl finds its script, loaded from r.wdfl.co or announcing its JavaScript object, on 4,799 live domains. After we set aside one platform's client portals, 2,648 of the rest match a company. That puts it 15th of 96 in Affiliate & Referral with a 1.52% share. The headline hides a second story, and it is the more useful one for anyone prospecting this list.

Count accounts, not domains

Rewardful's snippet carries an account key in a data-rewardful attribute, so we can see whose programme a page belongs to. We fetched the home page of every live domain and read a key on 2,716 of them. They held 1,672 different keys, about 1.6 domains per key. Most keys sit on one company's own sites. Some don't.

The largest single key belongs to Double, practice-management software for bookkeepers. Double's client portal, white-labelled on each firm's own subdomain (clients.firmname.com and the like), loads Double's Rewardful account. That is 287 accounting firms' domains, 5.94% of the 4,830 we checked, none of which runs an affiliate programme of its own, so we leave them out of every chart and table on this page. custom link domains hosted by Linkly (73), FeedBear's feedback boards (40), Pathwright's course sites (34), upcoach's coaching portals (21) and eleven smaller platforms do the same. All told, 552 domains, about one in nine, carry a platform's key; the 265 outside Double stay in the charts, 5.83% of the 4,543 we analyse. A few customers also own long tails of their own domains: one GRC certification body's key sits on 152 forwarding domains.

Sales signal: before you size a Rewardful list, drop client portals and hosted subdomains, then dedupe by account. What remains is a few thousand software companies, each paying for its own programme.

What the chart says, and what it doesn't

The usage chart reads 3,317 in June and 4,799 in October. Most of that rise comes from our side: the set of domains we crawl changes every month as dead sites drop out and new ones are found, and our detection widened over the summer. September to October was flat, 4,794 to 4,799. Exits are measurable. 1,144 domains dropped Rewardful on at least one hostname since we began tracking it on 16 March 2026, and 203 of those still run it on another hostname, so about 940 left it entirely in seven months.

"About one Rewardful domain in nine runs someone else's account. Strip those out and you find a few thousand young software companies, each paying to run its own programme." - Elif Arslan, CMO at TechnologyChecker.io

Sales signal: treat this as a stable pool, not a surge. The exits are the interesting accounts, since a company that drops affiliate tracking has either closed or changed how it acquires customers.

Who the customers are

This is a start-up product. 73.7% of matched companies have 1 to 10 staff, 21.59% have 11 to 50, and only 24 have more than 200. 56.26% were founded in the 2020s. The recognisable names are funded software companies running a self-serve plan: Synthesia, Riverside, VEED, HeyGen and OpusClip in video, Scribe and Manatal in workflow and hiring, ONLYOFFICE in office software. Several load Rewardful on the app itself, such as app.gptzero.me or auth.heygen.com, because that is where a referred visitor signs up and pays.

Rewardful says its customers bill through Stripe or Paddle, and that rule shapes the list. You won't find many shops or agencies here. You find subscriptions: software, courses, coaching, fitness memberships like Fit4Mom's on-demand platform and PushPress.

Sales signal: these teams are small and growth-led, and the affiliate programme is often owned by a founder or the first marketer. Pitch tools that recruit affiliates or create content for them, and keep the price close to Rewardful's own $49 to $149 a month.

Where they are

The United States has 1,267 of the 2,648 matched companies. The United Kingdom (213), Canada (136) and Australia (111) bring the English-speaking share to 65.22%. France is next with 74, then India (61) and Germany (52). Industry follows the same line. Software Development (23.59%) and Technology, Information and Internet (16.78%) lead. Before we set Double's portals aside, Accounting ranked third, and 163 of its 179 companies were those portals; now it is out of the top ten.

Sales signal: an English-language campaign covers two thirds of the market. A European push is small by comparison, and France is the only country outside the English-speaking four that reaches 70 companies.

Switching and overlap

None of the rival pairs passes our switching tests, so there is no migration table on this page. The overlaps are small. 60 Rewardful domains also run FirstPromoter today, out of 74 ever seen with both, and 35 run PartnerStack, out of 72. Since March, 12 domains dropped PartnerStack and kept Rewardful, while 8 went the other way. With Impact, 9 domains dropped Rewardful and kept Impact. Those are small numbers, and I wouldn't build a story on them.

"Rewardful, FirstPromoter and PartnerStack rarely share a site. A SaaS company picks one tool and keeps it, so the window to sell is before the programme launches." - Elif Arslan, CMO at TechnologyChecker.io

Sales signal: for a rival affiliate tool, the 35 sites running PartnerStack and Rewardful at once are the warmest list, since someone there is already comparing. For Rewardful's own team, PartnerStack's 3,131 domains are the natural prospect pool.

The stack around it

Across the 4,543 domains in our stack analysis, Google Analytics runs on 84.97% and Intercom on 14.99%. Stripe's script shows on only 25.51%, which surprised me until I remembered how Rewardful works: it reads payments from the Stripe account through the integration, so the marketing site never has to load Stripe.js. Paddle is on 1.76%. ProfitWell, a subscription-metrics product, is on 7.46%, and Vercel Analytics (6.8%) and Plausible (5.7%) show a developer-built, privacy-minded slice.

Sales signal: the typical Rewardful site is a SaaS marketing site with live chat and a self-serve checkout. Billing analytics, onboarding and in-app messaging tools fit this list better than e-commerce apps do.

What it costs

Rewardful's pricing page (checked 14 October 2026) prices by affiliate-attributed revenue: Starter is $49 a month for up to $7,500 of it, Growth $99 for up to $15,000, and Enterprise starts at $149 for up to $30,000. Every plan has a 14-day trial, unlimited affiliates and no transaction fee; optional Managed Payouts adds a 3% fee. The company was founded in 2018 and has been part of saas.group since November 2021.

Sales signal: a customer that outgrows $30,000 a month in affiliate revenue moves up Enterprise tiers. That is when buyers start comparing tools, so programme size is the timing signal.

Key takeaways

1. 4,799 live domains, 15th of 96, ahead of FirstPromoter (4,150) and PartnerStack (3,131).

2. About one domain in nine carries a platform's key; Double's 287 client portals are left out of the charts.

3. Small and young: 73.7% have 1 to 10 staff and 56.26% were founded in the 2020s.

4. English-speaking markets hold 65.22% of matched companies.

5. Rival tools rarely share a site, so the sale happens before launch.
