Limitless Labs brings more real customers and creators into what SACHEU is making next
For immediate release
While much of beauty races to let AI make the calls, the partnership with SACHEU is built to do the opposite — to help hear more of its real customers and creators, and keep every product decision human.
LOS ANGELES, Aug. 27, 2026 — Limitless Labs, an agentic AI company, and SACHEU, category-creating cosmetics brand, announced a partnership to bring more real customer and creator voices into how the brand decides what to make, launch, and improve.
"Social Mirror Audiences shows us where beauty creators are frustrated in their routines, the gaps and pain points nobody's solved yet, before we ever start developing a shade," said Sarah Cheung, Founder of SACHEU. "It's not about chasing what's trending. It's about spotting the white space that no one's filled and getting there first. The formulas, the risk, the creative call on what to actually build — that's still all us. Limitless Labs AI just makes sure we're pointed at the right problem before we start."
The technology behind it is GEN's Social Mirror Audiences, where GEN trained a custom audience just for SACHEU on thousands of real beauty creators. Each audience member builds from that creator's own content and stated preferences, not an invented persona — and reads what real shoppers are already saying, including more than 22,000 customer reviews across 22 SACHEU products and 184,060 social videos. A proposed shade, product, or claim can then be put in front of that whole audience at once leading to unique insights and a clearer read on what will sell.
The step that makes the answers trustworthy comes next. GEN refines the audience against SACHEU's own internal data, keeping the voices that correctly understand the SACHEU brand. On SACHEU's data that refinement lifted preference accuracy by about 30 percentage points over an unrefined audience — the difference between a plausible answer and one the brand can act on. What used to take weeks of small panel research takes days, and every answer traces back to real customer and creator voices.
Beauty is a category built on being heard. But a single comment thread, a passing trend, or a small feedback group can only show so much. The partnership gives SACHEU a way to listen more widely and more carefully — reading what thousands of real customers say in their reviews, and paying attention to what real creators respond to — so the quiet, repeated things people are already telling the brand actually reach the table.
Since January the partnership has produced a methodology that shapes real decisions:
- Reading the reviews, all of them. When SACHEU revisited the how-to-use guidance on its Peel-Off Lip STAY-N, the decision was informed by 7,391 real customer reviews — the people who actually use the product — not a hunch.
- Hearing the creators. What real creators gravitate toward helps SACHEU understand which shades and ideas resonate before committing to them. Ahead of one lip shade launch, the order the audience preferred three shades in matched the order they went on to sell in.
- Deciding with more of the picture. SACHEU can see where interest is strong, where it is split, and where the brand's own judgment needs to make the final call. One shade study drew on 184,060 social videos to show which shades had real pull and which were splitting the audience.
In every case, the people who know the brand best still make the decision. The listening just makes it better informed.
"This patent-pending technology allows brands to predict what will sell before they manufacture it by learning from their customers at a scale they never could before," said Dale Janée Schroeter, VP of Business Development at GEN. "Our AI agents give sharper answers because they are built on real, unique data sets."
The approach is intentionally bounded. It helps SACHEU hear more and understand more; it does not replace the brand's creative instinct, shade expertise, or the trust SACHEU has built with its customers and creators. SACHEU makes every product, launch, and brand decision — now with more real voices in the room.
