- Enterprise: $149+/month (over $30,000/month from affiliates)

Cello
Cello markets itself as a referral and partner platform. But the product was built for user referrals (inside your app) and that’s where it shines bright.
What Cello does well: you embed a referral widget into your authenticated product, and your existing users can refer friends without ever leaving the app. Attribution is automatic. Rewards are handled. For PLG companies where the user base is a growth channel waiting to be activated, it’s a clean solution.
What it doesn’t do well: external affiliate programs. Based on our observation, there’s no coupon code support. The partner-facing experience is relatively thin.
There are also two hard constraints. First, to install Cello you need frontend integration to your app or website and user authentication. Second, there’s a 5% transaction fee on partner referral payouts, on top of the subscription.
If you want to turn your existing SaaS product users into referrers, Cello is worth a serious look. However, if you want to recruit and manage independent affiliates (influencers, podcasters, newsletter writers, or agencies) it has some limitations.
Cello Unique Selling Points
- In-product referral widget embedded in your app
- User referrals and partner referrals from one platform
- Implementation typically a few hours with minimal dev resource
- Automated KYC, compliance, and fraud detection
- Performance-based pricing tied to referral ARR
Cello Pros and Cons
Pros of Cello
- Purpose-built for in-product, user-led referral growth
- Free to get started; costs scale with results
- Fast setup for product-led teams with an authenticated app
- Strong compliance and payout automation for user referrals
Cons of Cello
- Requires a logged-in web or mobile experience to function
- Affiliate backend too limited for affiliate programs that focus on external affiliate recruitment
- No affiliate coupon code support (that we’re aware of)
- G2 reviewers ware asking for more customizability features within the product, such as for landing pages, and filtering features.
Cello Pricing
- Free plan: up to €5k referral ARR
- Grow: €200/month (up to €50k referral ARR)
- Scale: €750/month (up to €100k referral ARR)
- Enterprise: custom
5% transaction fee applies to partner referral payouts.
Reditus
Reditus is one of the affiliate software that offers affiliate marketplace. When we went inside its marketplace, it has 25,000+ B2B SaaS affiliates on the platform who are actively browsing programs to join. If you’re launching an affiliate program from scratch and has no desire to recruit your partners manually, Reditus marketplace is a great shortcut compared to cold outreach.
But there's a catch: the marketplace is only accessible on the $239/month Scale Up plan. The free plan (up to $1,000/month in affiliate MRR) is enough to test how Reditus can support your affiliate marketing program. But if the marketplace is why you’re considering Reditus, that’s the plan you’re budgeting for.
Now, if you still want to do manual cold affiliate outreach, Reditus comes with the recruitment fundamentals: custom sign-up page, tracking, commission management, CRM integrations. But looking at how Reditus is built and marketed, it seems that that the platform is built around affiliate discovery first, and partner management second.
Reditus Unique Selling Points
- Marketplace of 25,000+ B2B SaaS affiliates
- AI affiliate recruitment feature for finding partners by industry
- Free plan available (up to $12k ARR via in-app referrals)
- Custom affiliate sign-up page and dashboard
- Integrations with Stripe, Paddle Billing, and major CRMs
- White-glove migration support on Growth and Scale Up plans
Reditus Pros and Cons
Pros of Reditus
- Marketplace access is a real head start for affiliate discovery
- Free plan makes it low-risk to test
- Built exclusively for B2B SaaS
- CRM integrations useful for larger sales-led teams
Cons of Reditus
- MRR-based pricing rises as the program grows
- Management tooling can be limited for more complex affiliate program structures
- More of discovery-first affiliate software
- A user left a G2 review, saying they wished to have more detail reporting
Reditus Pricing
- Free: up to $1,000 MRR from affiliates
- Starter: $71/month (up to $5,000 MRR)
- Growth: $119/month (up to $10,000 MRR)
- Scale Up: $239/month (up to $20,000 MRR)

How Rewardful Compares to FirstPromoter, Cello, and Reditus
Curious to see exactly how Rewardful stacks up when managing your program day-to-day? While all four platforms help you run affiliate campaigns, their underlying architecture and tracking logic are built for different SaaS growth strategies.
Here is a deeper look at the technical and operational differences between Rewardful and these three platforms:
Rewardful vs. FirstPromoter: Seamless Subscription Sync vs. Plan Caps
FirstPromoter severely limits its $49/month starter plan, capping your program at just 2 campaigns and $5,000/month in affiliate revenue. If you succeed, you are forced into an expensive plan change. Rewardful gives you unlimited campaigns on all plans, letting you scale your program freely without hitting restrictive structural walls.

Rewardful vs. Cello: External Influencers vs. In-App User Widgets
While Cello focuses on activating your existing user base from inside your app, Rewardful unlocks external growth channels. It gives you the infrastructure to scale a traditional affiliate program with outside partners like industry influencers, bloggers, and agency partners.

Rewardful vs. Reditus: 0% Fee vs. Extra Charge
Reditus charges you based on a percentage of your affiliate MRR, meaning they take a bigger cut of your revenue as your program grows. With Rewardful, you don’t have to pay extra for your success. It offers predictable, transparent, flat-rate pricing that protects your profit margins as you scale.

FirstPromoter vs. Cello vs. Reditus: Choose The Affiliate Tool That Aligns with Your Growth Strategy
Ultimately, choosing between these platforms comes down to how you plan to acquire your partners. If you want to tap into an existing pool of B2B SaaS publishers and don't mind paying a premium to access it, Reditus provides a built-in discovery engine. If your primary goal is to turn your active, logged-in software users into brand ambassadors via a native, in-app widget, Cello is built specifically for that workflow.
However, if your goal is to build an independent, highly scalable affiliate channel using external partners like influencers, bloggers, and agencies, you need a dedicated management platform. While FirstPromoter offers traditional tracking, its restrictive plan caps can penalize early success. Rewardful eliminates those arbitrary walls—delivering a deep, two-way subscription sync engine with Stripe, unlimited campaigns, and flat-rate pricing designed to protect your profit margins as you scale.
