Can YouTube Shorts significantly help grow a channel subscriber count?

Shorts are strong for discovery because the feed pushes them to non-subscribers but they convert to subscribers far less reliably than long-form does.

Use Shorts as the top of a funnel: get found, then point new viewers to long-form that earns the subscribe, rather than treating raw Shorts views as growth.

Make Shorts that represent your actual channel so they attract the right people, channels that post Shorts in isolation gather views while the subscriber line barely moves.

Shorts can genuinely help, with an important caveat about what they are good at. Their strength is discovery: the Shorts feed shows your clip to large numbers of people who do not subscribe to you, so a single Short that lands can put your channel in front of an audience that long-form alone would take months to reach. That is real and worth using. The caveat is conversion. A Shorts view is a low-commitment moment, someone swipes in, watches a few seconds and swipes on, so the rate at which Shorts viewers turn into subscribers is normally much lower than for long-form, where someone has chosen to spend ten minutes with you and is far more likely to subscribe. So Shorts can absolutely grow subscribers but they normally inflate view counts faster than subscriber counts and treating raw Shorts views as if they were growth is the common mistake.

The pattern that actually compounds is to treat Shorts as the top of a funnel rather than the whole channel. Use Shorts to get discovered, then give the new viewers a clear reason and an easy path to stay: make Shorts that genuinely represent what your channel is about (so the people they attract are the people who would enjoy your main content, not a random crowd), point viewers toward a strong piece of long-form and make sure that long-form delivers so the subscribe is earned. Channels that grow subscribers from Shorts normally pair them with consistent, substantial long-form that converts the attention, while channels that post Shorts in isolation rack up views and wonder why the subscriber line barely moves. So the honest answer is yes, significantly but only as part of that pairing, lean on Shorts for reach and on your core content for the reason to subscribe.

This is creator-side growth, so it sits outside what Flinque does and no tool, including Flinque, can grow your channel for you, that comes from the content and the funnel above. Flinque is a brand-side discovery and vetting tool, so the only point where it touches your world is the other direction: brands use it to find and check creators to partner with and a channel that is growing a real, engaged audience is exactly what they screen for. So the work that grows your subscribers honestly also makes you more discoverable to brands later. The growth itself, though, is yours to build through Shorts-for-reach plus strong long-form, not something software supplies.
