Think about the X accounts that matter in your world. The companies, the thought leaders, the media outlets, the conference accounts. Each one has a follower list, and buried in those lists are european blockchain developers. The problem is that X only lets you scroll through a long list of profile photos and short bios with no way to intelligently filter for the people you are looking for.
Blockchain developers build the smart contracts, protocols, and decentralised applications that power web3. In the blockchain space, community is everything - developers choose projects based on technical merit and community quality. Identifying which blockchain developers are following a given account reveals potential contributors, users, and advocates who are already paying attention to the project.
Catch The Good Ones fixes that. Add any public X account and we classify every new follower using customisable AI-powered filters you define in plain English. The european blockchain developers surface to the top, classified and ready to act on. It works for any account - your own, a competitor, a thought leader, a conference, a media outlet. If an account has followers, we can find the european blockchain developers among them.
From London to Berlin to Paris, Europe has a thriving ecosystem, and the key people in it are active on X.

We smart-compose a personalised DM so you can send it in one click.
Build a contributor pipeline for your project
Export blockchain developer followers to CSV and cross-reference with your GitHub contributors. Find developers who follow you but have not contributed yet - they are your next potential contributors.

Six steps. From adding an account to a fully automated pipeline.
Add a tracked account
Add any public X account - your own, a competitor, a thought leader, a company. We start monitoring their followers immediately.
Define your search
Describe who you are looking for in plain English. "Investors with 10K+ followers" or "Female tech founders in fintech". Our AI maps it to filters.
Run a sync
Syncs run automatically on your schedule (up to 4x/day on Pro). Every new follower is classified by job role, personality, skills, and more.
Explore your matches
Your dashboard shows only the people who match your criteria. Full profile, job title, personality traits, and the date they followed.
Export and act
Download upload-ready CSVs for tools like Apollo, Hunter, and Snov.io. DM people directly on X. Or connect via our API and Zapier.
Automate it
Schedule regular syncs and let the workflow run for you. Set up automated actions via Zapier or our API. Choose your notification preferences so you never miss a match.

Web3 projects hiring developers
You are building a protocol, L2, or dApp and posting about it on X. Blockchain developers follow you because they are interested in your tech. Identifying them gives you a pipeline of candidates who already understand what you are building.

How does Catch The Good Ones identify blockchain developers?
We classify every new follower using AI that analyses their bio, recent posts, and profile data. You define your filters in plain English - "Solidity developers", "Rust blockchain engineers", "smart contract developers" - and the AI matches followers against your criteria.
Can I filter by blockchain ecosystem or language?
Yes. Your filters are fully customisable. Search for "Ethereum developers", "Solana Rust developers", "Move language engineers", or any other description. The AI interprets your plain-English filters and classifies accordingly.
Does this work for finding developers in competitor ecosystems?
Yes. Track any public X account - competing protocols, blockchain foundations, developer DAOs. We classify their followers using your filters, so you can discover blockchain developers engaged with other ecosystems in your space.
Can I really track any public X account?
Yes. Any public account. You do not need to own it, manage it, or have any relationship with it. Just add the handle and we start classifying their followers against your custom filters.
How many accounts can I track?
As many as you want. Each tracked account is billed separately based on the tier you choose (Starter, Growth, or Pro), so you can start with one and expand as you see results.
Which European countries are covered?
All of them. If a profile lists any European location or organisation, they are classified as European. The most common signals come from the UK, Germany, France, Netherlands, Nordics, and Spain, but any European country is captured.
