Cold outreach is getting harder. The average cold email reply rate in 2024 was just 5.1%, down from roughly 7% the year before, and that number is still falling. Warm intros are 5–10x more effective at driving meaningful conversations than cold outreach. When someone vouches for your credibility, prospects are far more likely to engage.
The case for building a network-led growth strategy has never been stronger. But which tool do you actually use to execute it? Two platforms occupy this space for startup teams: Intro Stars and Scayul. They're both built around the power of warm introductions, but they approach the problem very differently, and which one is right for you depends on where your business is and what you're trying to build.
Introstars is a marketplace for high-value paid business introductions. Founded by Mike Adams, a former Apple, HP, and Zoom marketing executive who has attended over 1,000 networking events, the platform was built on a simple but powerful premise: genuine relationships are essential for successful business growth, and warm introductions are key to sustainable business success.
The model works like this: businesses post what kind of introductions they're looking for, and connectors in the Intro Stars network bring them those introductions in exchange for a success fee. Introducers use the platform for free. Those receiving introductions pay a monthly fee, and the system is aimed at professionals, entrepreneurs, B2B salespeople, and recruiters looking for a cost-effective way to generate warm leads and new business opportunities.
Two proprietary features sit at the core of the product; introprotect™ ensures that every introduction is safeguarded and that all parties honour their commitments, while introtracker™ lets members track all their introductions and get paid for closed deals.
For introducers, the earning potential is significant: payouts can range from £500 to £10k+ per successful referral.Scayul is a partner ecosystem platform for startup and tech teams who want to build a scalable, repeatable go-to-network strategy. Rather than facilitating individual introductions, Scayul is designed for teams that want to operationalise their entire partner programme - mapping shared accounts, managing relationships across a portfolio of partners, and generating warm introductions consistently across the whole team.
Where Intro Stars puts the connector at the centre, Scayul puts the partnership at the centre. The platform brings together account mapping, AI-assisted introductions, and shared workspaces so that partner-led growth stops being something that only happens when one person knows the right contact — and becomes a systematic, company-wide motion.
Despite 53% of B2B companies saying outbound isn't as effective as before, leveraging warm introductions can boost trust and credibility, but only if you have the infrastructure to make them at scale.

The honest answer is that Intro Stars and Scayul serve different growth moments, and for many startups, they're not really competing at all.
Introstars is a strong choice if you're in active business development mode, need a steady flow of qualified warm leads, or want to monetize your own network by making introductions for others. It's lean, incentive-aligned, and you can get moving quickly. If you work in B2B sales or marketing, it's a game-changer for lead generation - and if you're an entrepreneur or founder, it can help get those first precious introductions to paying customers.
Scayul is the right choice when you're ready to build partnerships as a growth channel - not just as a lead source. Once you have a set of technology partners, agency partners, or ecosystem relationships you're actively working, Scayul gives your team the tools to map those relationships to your pipeline, remove the friction from warm introductions, and turn partner-led growth into something predictable. Warm outreach can achieve response rates of up to 45%, while cold email campaigns struggle with just 1–5% - but getting those rates consistently requires a system, not just good contacts.
The bottom line: start with Introstars if you need introductions now. Graduate to Scayul when you're ready to turn those introductions into a repeatable engine.
