Twitter Threads vs TikTok Slideshows for SaaS

Twitter threads built half of the B2B SaaS brands that exist today. From roughly 2019 through 2023, a founder with a halfway decent writing voice could land 50k impressions on a Tuesday, attract a handful of investors and 200 sign-ups, and call it a launch.

That window is closed. Twitter (now X) impression mechanics changed twice since 2023, organic reach on long threads collapsed by ~70%, and the platform now favors short replies and video over multi-tweet structures. Meanwhile, TikTok’s slideshow format has gone in the exact opposite direction. Here is the actual math.

What a typical SaaS thread does in 2026

We tracked 60 SaaS founder accounts (10k-80k followers) and looked at their best thread of the past quarter. Median performance:

• Impressions: 18,400.
• Click-through to product: 0.6%.
• Sign-ups attributable to the thread: 24.
• Time to produce: 2-3 hours.

What a typical SaaS TikTok slideshow does in 2026

Same accounts, same products, slideshow format. Median performance over the past quarter:

• Views: 84,000.
• Click-through to product (via link in bio): 1.1%.
• Sign-ups attributable to the deck: 97.
• Time to produce with an AI slideshow maker: 5-10 minutes.

Why slideshows are winning

Three structural reasons, all algorithmic.

1. Completion rate is higher by design. TikTok rewards completion, and slideshows auto-advance with the music. A 9-slide deck at 3 seconds per slide is 27 seconds of guaranteed completion if the hook lands. A thread requires active scrolling all the way through, which most readers do not do past tweet 4.

2. The format is still under-supplied. Fewer than 1% of SaaS founders currently post slideshows on TikTok. Twitter threads have saturated supply — every B2B marketer writes them. Algorithmic boost goes to under-supplied formats. That is why a decent slideshow beats a great thread on raw reach.

3. Production cost has collapsed. A thread still takes 2-3 hours of writing. A slideshow used to take 3-5 hours of design. AI slideshow makers cut that to under 10 minutes, which changes the economics of the channel entirely. Threads cannot be sped up the same way — the value is the writing voice, which AI cannot fully ghostwrite for you yet.

Should you abandon threads entirely?

No. Threads still work for one specific job: building trust with a small audience that already knows you. If you have 20k+ engaged followers on X, your threads are likely your highest-conversion content for warm prospects.

What you should stop doing is treating threads as a top-of-funnel acquisition channel for a new SaaS. The reach math does not work anymore. Use threads to deepen relationships with people who already follow you. Use TikTok slideshows to find people who do not.

How to actually make the switch this week

Take your three best-performing Twitter threads of the past 6 months. Each one was a list. Convert each to a 9-slide TikTok deck.

• Slide 1: the hook (your thread’s opening tweet, rewritten as a single bold claim).
• Slides 2-8: the list points, one per slide.
• Slide 9: the CTA (your product link in bio).

If you do this manually it takes 3-5 hours per deck. With Slidetik, paste the product URL, pick the “feature list” story angle, and the system generates a 9-slide deck with copy and AI visuals in 60 seconds. Tweak the hook, post.

Three decks live in the same week as your next thread. Compare the numbers in 14 days. The math is going to surprise you.
