Meet Egyptian 3D concrete printing company Layn’s Zeyad Zein

🏗️ OUR FOUNDER OF THE MONTH — Every month, Founder of the Month looks at how a successful member of Egypt’s business or startup community got their big break, asks about their experiences running a company, and gets their advice for budding entrepreneurs. Speaking to us this week is Zeyad Zein (LinkedIn), co-founder and CEO of Egyptian 3D concrete printing company Layn.

Zeyad Zein will tell you he’s an engineer by study and an entrepreneur by life — that’s how he introduces himself. Zein studied architecture and construction management at Alexandria University, graduated, and founded Layn almost out of the gate. “It’s so weird and so hard to found something and have it work out,” he tells EnterpriseAM, “because you don’t have the expertise to run a multi-mn-USD company just yet.”

He still did it. Layn is Egypt’s first 3D concrete printing company — building its own hardware, software, and construction material in-house. In the roughly two years since its launch, the company has scaled from a prototype Zein was too embarrassed to show investors to five state-of-the-art machines running 24 hours a day, six days a week, and consuming 15 tons of concrete daily, with Sodic, Mountain View, and Emaar among its client roster.

The idea had been forming throughout university. Construction and real estate account for 20% of Egypt’s GDP, making it one of the largest sectors in the economy, and the technology powering it was, in Zein’s view, decades behind where it should be. “It’s a beautiful industry, very large, but outdated.” For Zein, it posed a challenge he welcomed with open arms.

His initial plan was to import the technology — that proved unrealistic. Industrial 3D concrete printers cost anywhere from USD 500k to USD 2 mn each, and Egypt’s foreign exchange dynamics made the financial model unworkable for local developers at those prices. Beyond the cost, the available technology didn’t meet his standards. “As Egyptians, we are very skilled in construction,” he says. “We didn’t find anything that met our standards so that it could work in Egypt.”

The alternative was to build it from scratch — hardware, software, and construction materials — and own the intellectual property entirely. That decision, which he acknowledges he did not fully understand the implications of at the time, turned out to be the company’s core advantage. “We didn’t initially realize that by building the technology ourselves, the control and benefit would be so incredible.”

Building it required a co-founder. Zein found one in Mohamed El Hashemy (LinkedIn), who brings roughly 15 years of experience in 3D printing across Egypt and Saudi Arabia and had previously co-founded Lamina, a company that built industrial-grade 3D printers for the jewelry industry. “Having a co-founder is like a marriage,” Zein says. “It’s so hard, and you need to be so lucky to find the right co-founder.” El Hashemy had an entrepreneurial journey with its share of ups and downs — which Zein considers an asset: he arrived with a map of what fails as much as what succeeds.

The company kicked off as a bootstrapped venture, soon awarded a grant from a European program. Then came investor interest: Dar Ventures’ Zeina Mandour and Nader Abou Shadi, alongside other angel investors, which gave the company enough breathing room to get going. To date, Layn has tested more than 300 tons of concrete in its development process, iterating on mix designs until the material performed to the standards the technology required.

Layn today operates across six product verticals: Urban Life, focused on hardscape and outdoor furniture; Walls, covering fences and boundary structures; Infra, producing manholes and urban infrastructure components; Spaces, targeting low-rise buildings; Skins, covering architectural facades; and Reefs, the company’s most unexpected offering, currently in development.

Reefs is perhaps one of Layn’s most interesting undertakings — one that holds impact beyond balance sheets: “According to public reports, around 60% of global coral reefs are damaged, unfortunately. To restore those damaged reefs, you need to 3D print artificial coral structures that you plant inside the natural reef area,” Zein tells us. “After a year, the coral adapts to its new habitat, and over one to five years, the actual coral reef grows back. So you restore the damaged reefs by creating the habitat.”

Why 3D printing? “Because you can create complex shapes according to their natural form. 3D printing is the only way to create voids and complex shapes.” Layn is currently completing R&D on the materials — seawater replaces tap water, and specific pH calibration is required — and expects to launch the vertical soon.

The team has grown from two people to 70, including blue- and white-collar workers, PhD holders, patent holders, and people who have worked across Lebanon, Saudi Arabia, and London. This is, in Zein’s view, unparalleled. “Tell me 10 companies globally that have five printers working 24 hours a day,” Zein says. “You won’t find them — not because they’re bad, but because of quality requirements and market demand. We were very lucky in Egypt to have both.”

For now, Layn is staying strictly within Egypt — though future expansions throughout Saudi Arabia and the UAE are on the horizon. Why? Egypt has more than enough scale, Zein argues. “One of the main reasons we’re delaying our expansion outside Egypt is simply the size of the Egyptian market.” The demand for printed urban furniture, fencing, and infrastructure across the new cities being built across Egypt’s coasts and desert is, in Zein’s framing, the bigger window than anything available regionally right now.

Layn’s trajectory since launch has been steep by any measure. The company has scaled its machine fleet, grown its headcount from two co-founders to a team of 70, and expanded its client roster to include some of Egypt’s most prominent developers — all within roughly two years of operation. What began with a shoddy prototype has become an operation running at full capacity, with demand out there in the bucketload.

Looking ahead, Zein says: “I don’t see Layn printing just furniture or fences — I think Layn will be printing cities with all their components. Three digital factories are planned: Digital Factory Cairo is already operational; DF White will serve the Mediterranean and North Coast; DF Red will serve the Red Sea. A mega-factory is planned for the early 2030s.

Looking back, the co-founder and CEO recalls being declined by a European VC, citing doubt that the company could succeed within Egypt. Zein’s response was succinct: “We built the pyramids.” The five machines running around the clock in Cairo today are, in his telling, the continuation of that argument — and he’s not done making it.

His advice to up-and-coming entrepreneurs? Don’t take advice from someone who hasn’t done it before.
