How Haléau used Substack to build trust before scale

In an industry addicted to acceleration, Haléau arrived slowly, and that restraint may be its most revealing choice.There was no launch crescendo, no influencer seeding spree, no breathless cascade of SKUs engineered for algorithms rather than people. Instead, founder Eleanor Pendleton began with a single product, a waitlist and an unusually open ledger. The result was demand, but more notably, loyalty.When Haléau officially entered the market late last year, more than 17,000 people had signed up for the waitlist. For an independently founded beauty brand, that figure alone would normally signal scale ambitions and a race to capitalise. Instead, what followed offered a clearer measure of momentum and sustained engagement.“Already we’re seeing strong repeat engagement [since October],” Pendleton told Inside FMCG. “Customers are returning to purchase additional shades or to gift the product to loved ones, alongside continued growth across our community channels without any paid media.”Pendleton is utilising the language of trust with its debut product, the Pearl Baume, which sits somewhere between makeup and object. It’s luminous, tactile and deliberately unhurried.The emotionally literate consumerIn a clean-beauty market that has matured past its early moral binaries, Pendleton is acutely aware that formulation alone is no longer enough.The consumer, particularly in prestige beauty, has become educated, sceptical and emotionally literate.“Consumers are discerning, educated and looking for products that don’t force a trade-off between skin health, luxury and artistry,” she noted.That insight matters as retail has spent the past decade chasing optimisation with faster, cheaper, more efficient products. Beauty, however, seems to be moving in the opposite direction.The shift toward “skin-first makeup” reflects a broader rebrand of value. Enhancement over concealment, longevity over novelty and feeling over function.Pendleton describes the brand as a “considered, timeless wardrobe of essentials,” a phrase that borrows from fashion’s more enduring traditions rather than beauty’s seasonal turnover.The open book: what retailers can learnWhat makes Haléau particularly compelling for retailers is how it was built. Pendleton did not manufacture mystery around the brand’s origins. Through an ‘Open Book’ Substack, she shared the realities of costs, delays, craftsmanship and compromise, an inversion of the industry’s usual polished opacity.“In theory, these final weeks should feel exciting. In reality? They feel like a balancing act between chaos, exhilaration, and exhaustion,” she wrote in early September, detailing airfreighted packaging, mounting nerves and the strain of holding a business and a household together at once.“This isn’t just business. It’s personal. It’s heart and hustle, poured into every ingredient, every choice, every step of the journey.”That openness continued through launch day itself. On the morning Haléau went live, Pendleton woke before dawn, switching the site on hours early, only to watch orders begin flowing in immediately.“The orders started rolling in – and they didn’t stop,” she wrote. “By the time the clock struck 8am AEST, we had already surpassed 100 orders. I was in shock.”What struck her most, however, was not the velocity but the community behind it. “The loyal readers who have followed me since my days at Gritty Pretty… believed in Haléau before a single product existed,” she wrote.In sharing both vulnerability and momentum in real time, Pendleton turned transparency into a trust mechanism that invited customers to feel genuinely invested.“I built Haléau in the open,” she said. “People felt invited into the process rather than marketed to.”That sense of invitation is critical as modern consumers are progressively auditioning brands for emotional alignment.Transparency, when done credibly, creates participation, and participation creates patience. The waitlist, therefore, was a community already invested in the outcome.In prestige beauty, restraint is proving more powerful than reach. US-based Glossier built early loyalty by launching slowly and prioritising community dialogue and repeat engagement over constant newness, while US brand Merit Beauty has kept its portfolio deliberately lean, opting for fewer launches and a measured cadence to build trust and longevity rather than chase hype.Across markets, these brands demonstrate that growth is being driven by emotional connection, a reminder that in beauty, loyalty is often earned through patience rather than pressure.A different educationThe pearl inspiration at the heart of Haléau is a personal choice, drawn from Pendleton’s childhood growing up near a pearl farm and her enduring relationship with the ocean.“[The product] allowed the community to root for the brand before they had even tried it,” she said. “That kind of connection is rare and very special.”For all its romance, however, Haléau is not naive about the operational realities of retail. Pendleton is candid about the learning curve involved in turning a concept into a trading entity.“Nothing fully prepares you for the operational realities of running a brand,” she admitted. “It’s an entirely different education.”What surprised her most, though, was emotion. The intensity of customer proximity. The way feedback lands as feeling rather than data.“One email from a customer can make your week; one packaging hiccup can keep you awake at night,” she said.This emotional exposure may be the hidden cost of direct-to-consumer intimacy, but it is also its advantage.Looking ahead, the brand’s growth strategy mirrors its launch philosophy. Expansion will be intentional, not fast.Additional Pearl Baume shades are coming, alongside complementary complexion products, including a pressed pearl-infused powder and a treatment-forward hybrid bridging skincare and makeup.“Sustainability is not a marketing message for us; it’s a responsibility,” Pendleton said. “We are committed to creating objects that endure.”For retailers watching the next evolution of prestige beauty, Haléau offers a useful provocation. The most powerful growth strategy is sometimes trust, built patiently.
