That\u2019s the type of grass Plantd makes into single- and multi-family housing panels from inside a former tobacco factory in Oxford, North Carolina.<\/p>\n<p>Read more <a href=\"https:\/\/durhammovinghub.com\/?p=2209\">The voice of the Canes pulls back the curtain. Why he\u2019s never missed a home game<\/a><\/p>\n<p>After five years, CEO Nathan Silvernail says his startup today is at an inflection point. He expects investors will double its valuation, currently in the low nine-figures, in a funding round later this year. The company continues <a href=\"https:\/\/www.newsobserver.com\/news\/business\/article294076974.html\" rel=\"Follow\" target=\"_blank\">to supply<\/a> the nation\u2019s largest home builder, D.R. Horton, on North Carolina projects. And in April, Plantd announced its first furniture contract (with a <a href=\"https:\/\/www.globenewswire.com\/news-release\/2026\/04\/27\/3281647\/0\/en\/plantd-expands-into-furniture-with-studio-tk-as-first-brand-partner.html\" rel=\"Follow\" target=\"_blank\">Johnston County manufacturer<\/a>).<\/p>\n<p>But is it ready to produce more panels, faster? How does a startup that celebrates its \u201cgratuitously carbon-negative\u201d environmental impact react to reduced U.S. policy interest in sustainability? And how long will the 92-worker company keep its headquarters in Oxford, a town of 9,000 north of Raleigh?<\/p>\n<p>\u201c2026 is that critical year when we\u2019re going from the R&amp;D role to full-scale production,\u201d Silvernail said in an interview last week with The News &amp; Observer. \u201cThen using that as that foundation to really kind of blast off.\u201d<\/p>\n<p>Blast off is apt phrasing. Silvernail met his Plantd cofounder Huade Tan while working at Elon Musk\u2019s aerospace company SpaceX. Both men were miserable there, Silvernail has said, but he still took lessons from that experience over to North Carolina.<\/p>\n<p>The N&amp;O conversation with Silvernail, which follows, has been lightly edited for clarity and length.<\/p>\n<p><b>N&amp;O:<\/b> What lessons did you learn from your time at SpaceX that you\u2019re applying at Plantd?<\/p>\n<p><b>Silvernail:<\/b> I started on like the first launch vehicle, right? I think SpaceX has launched like 500 rockets or something at this point. I started on like the first one. So, I got that experience of how to develop hardware, here\u2019s how you fly it once every two years, here\u2019s how you go to scale. Getting it to where we were launching once a week was a crazy gnarly learning curve. In hardware development, building one-of-one thing is a very different skill set than building 100 of that same thing, but I got to get both ends of that spectrum.<\/p>\n<p>That\u2019s the experience I\u2019m drawing on now. How we go from building one-of-one thing to, you know, a plan to build four or five, six or more every year of that same thing is the new challenge.<\/p>\n<p><b>N&amp;O:<\/b> What production advantages does Plantd bring to this industry?<\/p>\n<p><b>Silvernail:<\/b> It\u2019s the vertical integration aspect of it. I own my own machines; I don\u2019t have to depend on anybody else. I can build them as fast as I want, I can distribute them as fast as I want. And then at the same time, I have my own biomass.<\/p>\n<p>It\u2019s just like SpaceX. You enter Elon and his idea on, \u2018Hey, I\u2019m going to make these (rockets) reusable, which is going to allow me to drive all these costs down, while at the same time, I\u2019m going to vertically integrate. I\u2019m going to be the only rocket company that makes my own engines. I don\u2019t have to depend on all of these parts from other folks, that allows me to really, really aggressively control my prices.\u2019<\/p>\n<p><b>N&amp;O:<\/b> U.S. policies toward sustainability have changed drastically from the previous administration to this one. Has that affected Plantd\u2019s work?<\/p>\n<p><b>Silvernail:<\/b> It\u2019s notable, absolutely. I would say climate was sellable on the venture capitalist market for a long time. I think we started our company right at the tail end of that window, lucked out a little bit on timing, but then it shifted. Even during that time period, you couldn\u2019t charge for a green premium in a meaningful way. Nobody would rally behind them. Now it\u2019s even more true today.<\/p>\n<p>Read more <a href=\"https:\/\/durhammovinghub.com\/?p=2207\">Swarm of creatures made it seem \u2018the ground was moving\u2019 on NC island. See video<\/a><\/p>\n<p>You look at the new administration, the global economy and how that\u2019s impacting our economy here domestically, and we\u2019ve had to kind of reshift our focus. We don\u2019t change our ethos. Like our bread and butter is always around sustainability. It\u2019s showing that we can create engineered lumber and building materials in an efficient way when it comes to emissions and finance.<\/p>\n<p><b>N&amp;O:<\/b> Can you give an example of how the current administration\u2019s approach to environmental sustainability manifests?<\/p>\n<p><b>Silvernail:<\/b> Where that kind of shows up is not necessarily in the fluctuations on perspective of sustainability, but horrible operations, where you have government shutdowns every month. We had that kind of mass firing event from DOGE. That slowed the process (for processing applications for federal financing programs) down.<\/p>\n<p>The federal review phase that you have to go through was just constantly getting pushed out. And that\u2019s really where it showed up to make it difficult. I\u2019d say, for us, if we were starting in this market, and we were just now beginning, it would be a non-starter, most likely. Luckily, we\u2019re not in that phase.<\/p>\n<p>You know, the current administration and in the current climate, if you will, is very interested in American manufacturing and bringing jobs back to the country and bringing GDP back to the country, and so we fit really nicely into that category.<\/p>\n<p><b>N&amp;O: Why did Plantd choose to launch in North Carolina?<\/b><\/p>\n<p><b>Silvernail:<\/b> I think the mix between agriculture and industry here is really, really advantageous for what we\u2019re trying to do. When you\u2019re bringing new technology plus a new supply chain and everything involved into the mix, being able to co-locate all of that as much as possible is ideal, and North Carolina and South Carolina, I\u2019d say, are really more of the regions where that\u2019s possible.<\/p>\n<p>If you look at the kind of mega region of Charlotte, Raleigh and Greensboro being developed, all of our product for the next few years will be utilized directly in this region. So it also offered an advantage in that regard.<\/p>\n<p><b>N&amp;O: As you grow, do you see Oxford being your HQ going forward?<\/b><\/p>\n<p><b>Silvernail:<\/b> This is going to be our manufacturing hub. This won\u2019t remain our HQ. For now, it\u2019s kind of everything. It\u2019s where we do our <a href=\"https:\/\/www.youtube.com\/watch?v=Ex5no5bEpvI\" rel=\"Follow\" target=\"_blank\">tissue culture cloning<\/a>, it\u2019s where we do our manufacturing, our engineering, our production, all of that. The future aspect of this will be a manufacturing hub for the lumber products, as well as the machines that produce them, and then we\u2019ll be expanding out domestically and internationally with the machines that we produce here. But as far as where our HQ might live in the future, I don\u2019t have any thoughts around that yet.<\/p>\n<p><b>N&amp;O: So long-term headquarters, probably not Oxford?<\/b><\/p>\n<p><b>Silvernail:<\/b> I think longer-term, especially as we look more into rapid high-level expansion, I need to start robustifying my administrative team, my executive team, and all of that. Oxford is fantastic for engineers, technicians, agriculturalists, and all of that, but when it comes to actually running the company, it\u2019s a little bit shorthanded.<\/p>\n<p><b>N&amp;O: You mentioned your finished products are mostly in North Carolina. Where are they going?<\/b><\/p>\n<p><b>Silvernail:<\/b> I mean, they\u2019re going right down the block, pretty much. They\u2019re staying very local. The demand here is incredibly high.<\/p>\n<p>Read more <a href=\"https:\/\/durhammovinghub.com\/?p=2205\">Is swimming allowed in Triangle lakes &amp; rivers?
