The individuals that us-based startup founders follow on X reveal who is engaged in your space. When someone follows a thought leader, an industry voice, or a prominent individual, they are signalling interest in that person's domain. But X only lets you scroll through follower lists one profile at a time - no filtering, no classification, no way to find the us-based startup founders among the noise.
Startup founders are some of the most active and engaged people on X. They share what they are building, engage with people they admire, and follow accounts that inspire or inform them. For anyone who invests in, recruits from, or sells to startups, knowing which founders are paying attention to a given account is a high-signal indicator of market interest.
Catch The Good Ones lets you track any individual's X account and classify every new follower using customisable AI-powered filters you define in plain English. Track the thought leaders and prominent figures that attract the us-based startup founders you care about. When they gain new followers matching your criteria, those people appear on your dashboard - classified and ready to act on.
The US dominates this space globally, and the people shaping it are active on X.

Recruit founders or their teams
A startup founder who follows you is already a fan. If their company is pre-product or winding down, they might be your next hire. If their company is thriving, their team might be too.
We smart-compose a personalised DM so you can send it in one click.
Build a prospect list of startup customers
If you sell to startups, your follower list is a warm prospect list. Export founder followers to CSV, enrich with company data, and prioritise outreach to the ones already paying attention.

| Sarah Chen | Venture Partner | 45.2K |
| Marcus Thompson | Managing Director | 28.7K |

Founders who follow you might be building something complementary. Identify them, explore synergies, and start conversations that could lead to integrations, partnerships, or joint ventures.

See how it works for youFrequently asked questions
How does Catch The Good Ones identify startup founders?
We classify every new follower using AI against your customisable filters. Founders are commonly identified by bio signals like "founder", "co-founder", "CEO", or startup-related language. But you define exactly what matters - you might search for "technical founders in fintech" or "solo founders with 5K+ followers".
Can I find founders at specific stages?
Yes. Your search filters can target stage signals - for example, "pre-seed founders" or "founders who recently raised Series A". The AI uses bio and posting signals to match against your criteria.
Can I track who follows my competitors to find founders interested in my space?
Yes. Add any public X account as a tracked account. If your competitor sells to startups, tracking their account reveals which founders are in their audience - and potentially yours.
What types of individuals should I track to find startup founders?
Thought leaders, industry voices, conference speakers, and prominent figures in your space. The startup founders who follow these individuals are typically the most engaged and relevant people in the ecosystem.
Does the person I track know I am monitoring their followers?
No. We only access publicly available data. There is no notification to the account owner or their followers.
How do you identify US-based profiles?
Our AI analyses bio text, location references, and posting patterns. Profiles that reference US organisations, cities, or institutions are classified as US-based. This catches clear signals from bios and professional affiliations.
