Tell if AI
Runs fleets of AI agents that post human-passing content across social platforms for brands.
Tell if AI sells AI accounts built to pass as human, right as platforms move to detect that and models make the content itself free to copy.
Tell if AI creates posts and videos using artificial intelligence and posts them on social platforms like TikTok and Instagram to help companies grow their audience. The problem is that big platforms like TikTok and Meta are now requiring labels that say content is AI-made, and they are getting better at detecting it. This makes the main reason to use Tell if AI, which is hiding that the content is fake, go away. At the same time, cheaper tools that do the same thing are launching, and the platforms themselves could ban AI content altogether or change their rules tomorrow. The one thing that could change this is if Tell if AI finds a way to help companies do something the platforms actually want, instead of relying on a trick that platforms are actively shutting down.
Tell if AI announces a Series A or new named client beyond the single telehealth partner. Would show investor conviction and customer traction despite structural risks.
Tell if AI's telehealth partner faces FTC-adjacent marketing scrutiny or ends the partnership. Would show its only disclosed customer relationship is unstable or regulatorily exposed.
- 2 employees listed in YC directory
- 1 disclosed customer: a telehealth clinic partner
- Founded 2025, part of YC Fall 2025 batch
- Platform AI-labeling and provenance detection could kill the 'indistinguishable from human' pitch within 6-12 months.
- Crowded field of better-funded faceless-content tools commoditizing the same feature set.
- Single disclosed client in telehealth vertical facing FTC-adjacent marketing scrutiny risk seen at peer MEDVi.
- Revenue-share pricing tied to platform-controlled distribution that can be revoked by policy changes.
- Two-person team with no reported funding beyond YC batch slot limits ability to scale or defend share.

- Is Tell if AI profitable?
- No public revenue or profit data exists. Tell if AI runs on revenue-share deals with client brands rather than flat fees, per its YC profile, and as of July 2026 discloses only one client, a telehealth clinic, with no independent confirmation of results or revenue.
- Could AI replace Tell if AI's own business?
- Arguably it is already happening. Tell if AI's core offering, AI-generated posting across TikTok, Instagram, YouTube and X, is matched by ReelFarm, Clippie AI, Korpi AI and APOB.AI, all shipping similar faceless-content automation directly to brands as of mid-2026.
- Who owns Tell if AI?
- Tell if AI is privately held, founded in 2025 by Austin Stone and Ilariia Belova, and is part of Y Combinator's Fall 2025 batch. No parent company or funding round beyond YC's standard batch investment has been publicly reported as of July 2026.
- Who is Tell if AI's biggest competitor?
- Tell if AI competes with faceless AI-content tools ReelFarm, Clippie AI, Korpi AI and APOB.AI, which ship similar automated posting features directly to brands as of 2026, per Clippie's July 2026 blog and Korpi's March 2026 tool ranking, potentially bypassing agencies like Tell if AI.
- Will TikTok's AI-labeling rules hurt Tell if AI?
- Likely. TikTok and Meta require AI-content labeling and auto-detect provenance metadata as of July 2026, directly threatening Tell if AI's pitch of running accounts 'indistinguishable from human creators,' per reporting dated 2026-07-04.
- Does Tell if AI have any funding?
- Tell if AI is a Y Combinator Fall 2025 batch company, which typically includes YC's standard investment, but no independently confirmed funding amount, seed round, or valuation has been reported as of July 2026, unlike peer telli, which raised $15M that same month.
