Deno 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. 177 public profiles were available, 23 were unavailable or protected, and 52 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 Roles are self-described and can be incomplete or outdated.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.
