If you are building a partnership or referral motion for your SaaS business in 2026, you have probably come across both Scayul and Cello. On the surface, they sound similar: both help you grow through introductions and referrals rather than paid acquisition. But they are built for fundamentally different use cases, and choosing the wrong one could mean investing time and money into a tool that does not actually solve your problem.
This article breaks down what each platform does, where each one excels, and how to figure out which one belongs in your stack.
Cello is a user referral platform built for SaaS companies that want to turn their existing user base into a growth channel. It describes itself as an all-in-one referral platform that lets you launch a partner and user referral program on autopilot, with users like Typeform and Fellow relying on the platform to accelerate their flywheel.
The core mechanic is straightforward: Cello embeds a referral widget directly into your product, so your existing users can share a referral link with their network. When someone converts through that link, the referrer gets rewarded automatically. The platform integrates directly with Stripe and other payment providers for fully automated attribution and success-based payouts, with real-time performance tracking built in.
Cello's pricing starts at a Free plan supporting referral ARR up to $5,000, with the Grow plan at $350 per month for referral ARR up to $50,000, and the Scale plan at $750 per month for referral ARR up to $100,000.
Cello is well-reviewed for what it does. Users consistently highlight the streamlined onboarding process, the quality of customer support, and the success-based pricing model as standout strengths.
Scayul is a partner ecosystem platform built for SaaS companies with mature partnership teams. Where Cello focuses on turning your users into referrers, Scayul focuses on helping partnership professionals build, manage, and activate strategic partner relationships.
The core mechanic works differently. On Scayul, users share a profile page. Other users in the network can visit that page and request introductions to contacts in the page owner's network. The owner approves or rejects the request, and Scayul's AI drafts a warm introduction email that is sent organically through Gmail or Outlook. The result is a warm, personalized introduction rather than a generic referral link.
Scayul also includes two additional features designed for partnership teams:
Navigator allows users to prospect for potential partners across the Scayul network using a tag-based taxonomy, filtering by business type, role, and ideal prospect profile to surface relevant partnership opportunities.
Partner Overlapping enables account mapping between two companies that both have an active CRM connected, surfacing shared customers and leads to identify co-selling opportunities.
Scayul currently integrates with HubSpot, with additional CRM integrations in development.
This is the most important distinction. Cello is built for user referrals: your customers refer other potential customers in exchange for a reward. The referral is user-to-user, and the platform is optimised for volume and automation at that layer.
Scayul is built for partner introductions: your strategic partners (other SaaS companies, agencies, consultants) introduce your business to their network contacts. The introduction is partner-to-contact, and the platform is optimised for quality, context, and relationship depth.
If you want to run a referral program where your end users share links with friends and colleagues, Cello is the right tool. If you want to build a network of strategic partners who actively introduce you to potential customers and vice versa, Scayul is the right tool.
In Cello, the referrer is typically your existing customer or user. The referral link is impersonal by design: it scales because it requires minimal friction from the referrer.
In Scayul, the introducer is a strategic partner with a relationship to both parties. The introduction is personalized: an AI-drafted email that reflects the context of the relationship and the specific reason the two parties should connect. This creates a fundamentally different quality of first contact.
Cello's core differentiator is that it is built for in-product user referrals rather than traditional affiliate programs.
Its network effect comes from the volume of users sharing within your product.
Scayul's network effect compounds differently: as more partnership professionals join the platform, the Navigator feature becomes more powerful, surfacing a broader and more diverse set of potential partners. The value of the network increases for every user as the platform grows.
Cello uses shared-success pricing, meaning you only pay when your program generates revenue, with the option to start free and scale without upfront costs.
Scayul operates on a flat monthly subscription at $79 per month, which means your cost is predictable and does not scale with revenue generated. For partnership teams generating high-value introductions, this is typically the more cost-effective model.
Cello is designed for automated setup within hours and integrates natively with your existing tools.
Because it requires embedding a widget inside your product, you do need some development involvement at setup.
Scayul connects via CRM integration (currently HubSpot) and does not require in-product embedding. Setup is handled at the account level rather than the product level.
Cello is excellent at what it does, but there are clear boundaries to its scope. While Cello can technically handle affiliate programs, that is not what it is built for. Its strength is enabling in-product referral programs among users. If your goal is to work with creators, influencers, or publishers who take affiliate partnerships seriously, it is not the right platform.
More broadly, Cello does not help you with strategic partner discovery, account mapping, relationship management, or the kind of warm business introductions that partnership managers facilitate on behalf of their companies. It is a referral tool, not a partnership tool.
Scayul is not designed for user referral programs. If you want your end users to share a link with their network and earn a cash reward, Scayul is not the right fit. It is built for partnership professionals managing strategic relationships, not for consumer-style referral loops.
Scayul also has a cold-start consideration: the value of the platform increases as your network grows, so early adopters benefit most from building their presence on the platform while the network is still forming.
The honest answer is that for many SaaS businesses, these tools are not in competition at all. They solve different problems at different layers of the growth stack.

Choose Scayul if:
For businesses that want both, running Cello for user referrals and Scayul for strategic partner introductions is a reasonable combination: each operates at a different layer of the growth funnel and they do not overlap in functionality.
Both Scayul and Cello are built on the same underlying insight: warm introductions outperform cold outreach. But they operationalize that insight in very different ways and for very different audiences.
Cello is the right tool if you want to scale peer-to-peer referrals from within your product. Scayul is the right tool if you want to build the kind of strategic partner network that turns warm introductions into a consistent, high-quality pipeline. For partnership professionals building an ecosystem-led growth motion in 2026, Scayul is purpose-built for exactly that job.
