Heywear

Heywear was Martin Källström's third venture and his first outside pure software/hardware: a same-day optical retail startup in New York City, built to compress the entire prescription-eyewear process — eye exam, frame selection, lens edging — into a single 30-minute visit for one flat price. Conceived at the end of 2018 by a small, French-inflected founding group and steered day-to-day by an American hospitality-and-operations CEO, Heywear opened its NoHo flagship in March 2021, expanded to as many as five New York locations by mid-2022, raised a few million dollars from hardware- and infrastructure-focused investors, and then quietly closed all its stores by around 2024. Martin's own name barely appears in the company's regulatory paper trail — a detail that, on its own, tells part of the story of what kind of co-founder he was here.

Origins: a bad glasses-buying trip becomes a company (2018–2019)

Corentin Macias's frustration with American eyewear. Macias hadn't needed glasses until adulthood, and when he finally had to get a prescription filled he was stunned by how convoluted American optical retail was — a separate appointment for the eye exam, another trip to an optician to try frames, a third visit for fitting and adjustment. At the time he was working as an investment analyst at the Paris hardware fund HCVC (Hardware Club), and he used the vantage point of a VC evaluating hardware deals to dig into just how underserved the U.S. optical market was — three out of four American adults need glasses, he noted, and the healthcare system offers far less of a safety net than in France. He began laying the groundwork for what became Heywear at the end of 2018. French Morning ↗, Research ↗

The model: one visit, one price, no surprises

Heywear's real innovation wasn't a piece of hardware — it was operational. The company built a vertically integrated, direct-to-consumer retail model: it designed its own frames, ran its own stores, employed its own doctors, and owned its own medical-tech and software stack, including small on-site optical labs that cut and edged lenses while the customer waited rather than shipping the job to an outside wholesale lab.

Flipping the traditional order of operations. At a conventional optical shop, customers pick frames only after finishing their eye exam. Heywear reversed the sequence: customers chose frames first, so the on-site lab could start grinding and edging lenses to the (soon-to-be-confirmed) prescription while the exam was still underway — collapsing what is normally a multi-day, multi-appointment process into one visit.

The NoHo flagship

Full operational detail — location, customer flow, virtual queue, equipment — lives on the dedicated project page: Heywear NoHo Studio.

Heywear's flagship studio opened at 363 Lafayette Street at Bond Street in Manhattan's NoHo neighborhood in March 2021, stocking more than 3,000 distinct lens types on-site to handle volume without outside dependencies. Research ↗, French Morning ↗

Clinical technology

Heywear's speed depended on real diagnostic hardware, not just process design. The company installed a Visionix VX 120+ multimodal screener in February 2019 — well before its public launch — a fully automated device that maps the anterior segment of the eye in roughly 90 seconds. It objectively measures visual acuity via wavefront aberrometry, assesses corneal shape through topography (catching complex astigmatism), measures anterior-chamber angles to flag glaucoma risk, and screens for cataracts.

Brand & design

Center's brand identity. Heywear commissioned CENTER, an award-winning Brooklyn-based design studio founded by Alex Center (known for brands including Vitaminwater, SmartWater, Kin Euphorics, and Good Light), to build its visual identity from scratch. Center's own framing of the brief: "Our branding is a celebration of both sides of the experience, bridging the gap between the technical process of optometry and the gift of self expression."

Leadership: Pascocello as CEO, and the question of Martin's role

Jaclyn Pascocello's path to Heywear. Pascocello's career ran from Wall Street (stints at Smith Barney, Merrill Lynch, and Cowen, per a research compilation) into hospitality operations at Hillstone Restaurant Group, where she said she mastered "human behavioral psychology and premium customer service" managing high-volume restaurants. From there she became COO of Spacious, a startup that converted empty daytime restaurants into drop-in coworking space and was later acquired by WeWork — direct-line experience in turning underused physical space into a fast, repeatable customer flow, which she then brought to Heywear as its operating and public-facing CEO.

The notable gap in the SEC record. Heywear Inc. filed four Form D exempt-offering notices with the SEC between January 2020 and May 2021. Martin Källström does not appear as a related person — officer, director, or promoter — on any of the four. Alexandre Jais is listed as an executive officer continuously across all four filings; Jaclyn Pascocello joins as an executive officer starting with the February 2021 filing; Idan Cohen appears as an executive officer only on the earliest, 2020 filing; and the board of directors named across the filings — Alexis Houssou (2020–2021), and, from February 2021, Romain Afflelou and Marc Menasé — likewise never includes Martin. Read plainly, this is evidence that whatever role Martin played at Heywear, it was informal and strategic rather than a filed corporate office — a materially different footing than his roles at Twingly or Narrative, where he was CEO of record.

Growth and expansion

Closure, ~2024 — and why

By 2024, industry observers and consumer reports confirmed all of Heywear's New York retail locations had permanently closed. What follows draws on an AI research compilation's forest-level analysis of the company's arc, not on a contemporaneous closure announcement, and should be read with that caveat. Research ↗

The research's headline judgment: Heywear "succeeded brilliantly as an operational and technological proof-of-concept, but faltered as a sustainable enterprise, ultimately demonstrating that while technology can accelerate manufacturing workflows, it cannot easily untangle the deeply entrenched regulatory, financial, and physiological realities of the American vision care market."

Legacy in wearable technology

Heywear sits inside Martin's longer arc in wearable and body-adjacent hardware. He has connected it directly to Narrative Clip and, later, to Meta's AI glasses — arguing Meta finally fulfilled a vision both of his own earlier ventures were reaching for: hardware that captures your world and runs capable AI on top of it. Where Google Glass failed, in his telling, by being "too nerdy and techy and looked very dangerous," Meta succeeded by getting the form factor right and shipping strong multimodal AI alongside the hardware. ▶ 2:35, ▶ 3:01

Personal context: New York and an opening to plurality

Martin split his life between New York and Sweden through the Heywear years, and by his own account the period brought an identity crisis alongside the business one. He discovered Eckhart Tolle's The Power of Now, which reframed how he understood emotion and selfhood: "Du är inte dina tankar och du är inte din kropp. Tankar, känslor och smärta är någonting du har, inte någonting du är" (You are not your thoughts and you are not your body. Thoughts, feelings and pain are something you have, not something you are). ▶ 3:25, ▶ 6:59

After returning to Sweden and rereading the book with fresh eyes, then moving back to New York, he met a polyamorous woman on Tinder who became his guide into a new relational world — an awakening to plurality, both philosophical and relational, that he has said ran alongside the Heywear years. ▶ 7:54
