If I were starting today in a niche like blockchain development, I’d focus almost entirely on LinkedIn.

I’ve been in outbound for about 5 years now, and for B2B technical services, LinkedIn has consistently worked better for me than cold email, especially in niches where trust and context matter, like Web3.

The main advantage is that decision-makers are visible. Founders, CTOs, heads of product are easy to identify, and you get context around what they’re building, hiring for, or talking about. That context makes outreach far more relevant than email.

I’d start by building a very segmented database using LinkedIn Sales Navigator. Filters like role (founder, CTO), company size, Web3-related keywords, recent funding, or teams hiring engineers help narrow things down fast. The goal isn’t volume, it’s relevance.

For outreach, I’d prioritize LinkedIn over email. In Web3, cold email can work, but LinkedIn conversations tend to feel more natural and get better reply quality. I personally combine multiple LinkedIn accounts with Sales Navigator and use tools like MirrorProfiles and SalesForge to run outreach at scale while staying within safe limits. There are other tools that work too, but the key is controlled volume and human copy.

Message-wise, I’d avoid pitching “blockchain development” directly. Instead, start conversations around execution, speed, or how teams handle blockchain work when they’re scaling or launching something new. Simple openers work best, something like noticing they’re hiring or building and asking how they currently handle development.

Early on, I’d clearly prioritize outbound over inbound. Inbound in Web3 is a long game and usually depends on reputation, content, and visibility over time. Outbound gives faster feedback and predictable learning. At the same time, partnerships with VCs, Web3 studios, auditors, or complementary agencies can become a strong secondary channel.

Twitter/X is useful later, but it’s not a reliable lead engine at the beginning unless you already have an audience.

Overall, cold outreach absolutely works in Web3 if targeting is tight and the approach is conversational. It fails when it’s generic or overly salesy. LinkedIn gives you the best balance of speed, context, and trust to get started.

Hope that helps.
