How Joiin Built a SaaS Affiliate Channel from Zero to €130K+ ARR (Using an Affiliate Network Approach)

“We started from zero; no affiliate program, no strategy, nothing. Reditus helped us go from that to over €130K in Annual Recurring Revenue (ARR), without needing to hire or manage a partner team. If you’re a SaaS company looking for a scalable, low-maintenance growth channel, this is it.”



Paul Shipway, CCO at Joiin

When Joiin first began working with Reditus, they had no affiliate program in place. They had no affiliate network, no strategy, and no infrastructure. Their growth was driven by their product, organic channels and paid ads.

Joiin believed that affiliate marketing could become a scalable acquisition channel but they were not sure exactly what to expect. They trusted Reditus and the guidance of founder Joran to help define the structure, tactics, and strategy for their SaaS affiliate programme.

Building the Affiliate Program and leveraging our Affiliate Network

Within three months of the first setup steps, Joiin recorded its first affiliate‑driven sale. This period accounted for recruiting the early affiliates, integrating tracking, and onboarding partners. They were aware that starting from zero meant that initial ramp periods tend to be slow, as you adding one more layer to your sales cycle.

The internal demands at Joiin remained light. The CCO led the initiative, with support from development resources for tracking integration. Joiin did not need to hire a dedicated affiliate program manager, Reditus did all the heavy lifting for them to star with. Reditus handled marketing of the affiliate program, recruitment & activation of the affiliates. When they started to generate revenue, we started to take care of the payouts, allowing them to save time & the worry about tax compliancy.

After a year, a challenge emerged: a small set of affiliates started to bid on Joiin’s brand keywords using affiliate links. To preserve integrity, Reditus built a fraud detection system and started to flag suspicious behavior. This allowed Joiin to remove or sanction affiliates violating rules, protecting margins and reputation.

Growth, Metrics & Compound Effects

Over the span of their first eighteen months, Joiin’s affiliate program evolved into a meaningful revenue stream:

• 373 affiliates signed up
• ±20% of the affiliates generated clicks
• 25 affiliates contributed referrals
• Over €80.000+ in lifetime affiliate‑driven revenue
• €130.000+ ARR currently attributable to affiliate channel
• Joiin’s only ongoing cost is the subscription to Reditus US$299/month and the affiliate payouts for the first 12 months.
• Estimated share of new revenue from affiliate channel: ~10%

The growth curve shows the compounding nature of affiliate marketing. In year one, Joiin scaled from zero to approximately €2,500 MRR. In year two, they grew from €2,500 toward €10,000+. That acceleration is typical once momentum builds in an affiliate program and leveraging a network.

Because Joiin pays 40% commission for 12 months, the acquisition economics are predictable. They know exactly what they will pay per referred paid customer, and don’t have to worry about spending money on unqualified sign ups. Because their retention and renewal rates are strong, they can reliably model lifetime value and profits, making the affiliate channel a lower risk investment.

When you look at the numbers, they are doing things on benchmark averages. Of the 373 affiliates, around 70 are active (i.e. generate clicks) and 25 produce referrals. When you are new to affiliate marketing, this might be suprising; but it is quite normal and on benchmark to have ±10-20% only to be active. It is good to remember that the 80/20 rule is also very common for Affiliate marketing; 20% of your affiliates, will drive 80% of the revenue.

Attracting the right, and relevant affiliates will therefore be important.

Why the Case Matters & Strategic Lessons

This case is especially potent for two reasons. First, Joiin managed to reach ~€12K MRR in affiliate‑driven revenue with virtually no ongoing effort from their side. After the initial setup, the recruitment help from Reditus the system started running fairly passively. Ideally you would spend more time & effort in growing the channel, but as any startup there is only limited time and efforts to put into certain things.

Going from zero to ~€12K monthly affiliate revenue with only a single internal owner is a powerful proof point. It shows that a SaaS company, with good Product Market Fit can adopt an affiliate network strategy without adding a heavy internal burden.

The results underline how a strong an affiliate network, recruitment engine, attribution transparency, and fraud tools are critical. Without the marketplace exposure and recruitment support, Joiin’s results would likely have been far weaker.

Advice for SaaS Teams Building an Affiliate Channel

Expect a delay before traction. The early months may seem slow if you are not recruiting affiliates yourself; but perseverance is key. Focus on recruiting quality affiliates who align with your audience rather than just high numbers. Build clarity in attribution, payout rules, and fraud management from day one. Leverage an established affiliate network or marketplace rather than building everything yourself. Over time, affiliate marketing compounds, as more partners join and learn what works, revenue accelerates.

Goals & Next Steps

Joiin’s target now is ambitious: to grow the affiliate channel toward €100,000 MRR. Expansion across geographies, recruiting top‑tier affiliates, and deploying AI or automation to reduce manual work are part of the roadmap. The affiliate network will continue evolving into a major growth lever for Joiin’s SaaS marketing strategy
