LlamaIndex Follower Analysis.

We paginate the provider’s follower-ID list until it reports completion, deduplicate it, then take a seeded random sample without replacement. Random selection is within that returned list; X and provider coverage may omit followers. Collection is not an atomic snapshot of all followers.

All 200 selected IDs remain in the denominator. 194 public profiles were available, 6 were unavailable or protected, and 80 available profiles had empty bios. Unknown information is not a negative-fit label.

Classification uses conservative public-bio text rules, followed by an AI-assisted profile-by-profile review. Roles are self-described and can be incomplete or outdated. We do not infer roles from a name, account popularity or a company affiliation alone. Percentages are rounded and may not add to exactly 100%.

• Developer + founder: Explicit software/engineering role and founder signals.
• Developers & engineers: Explicit software development, data, infrastructure or engineering leadership roles.
• Other founders: Founder signal without an explicit developer role; the business may be outside tech.
• Other software builders: Explicit indie-hacking, app-building or software-making signals without a developer/founder role.
• Other stated roles: A stated professional role outside the categories above.
• Organization accounts: Accounts explicitly describing an organization or product rather than a person.
• Not enough information: Unclear, empty, unavailable or protected bios. This does not mean poor fit.

The chart assigns developer-founders first, then developers, founders, other software builders and other roles. Explicit organization accounts are separate. A founder role alone does not establish a developer audience or a matching business.
