Here are the 30+ startups showcasing at HAX’s May 1 Demo Day

A few weeks back, TechCrunch ventured out to New Jersey to pay an early visit to HAX’s Newark offices. As much as I complained about the 90-minute commute in from Queens, it’s nothing compared to the last time I paid a visit to the SOSV-run hardware accelerator’s Shenzhen space.

HAX’s China operations have shrunk considerably since then, courtesy of a global pandemic and all of the ensuing lockdowns. That space had remarkable proximity to the global supply chain. One simply had to walk downstairs into mall-like spaces, filled wall to wall with component vendors.

In some ways, the Newark space is a reflection of the Shenzhen offices. There’s a faint sense of déjà vu, entering through the doors and spotting the familiar stadium seating where company and startup meetings are held. The China offices were far more lived-in by the time I visited. As the first news organization to visit the HAX space, we were greeted with walls of boxes awaiting the recycling truck — a familiar sight to anyone who’s ever moved office or house.

One key thing the new office has is plenty of space. The Newark “flagship” is 35,000 square feet, funded — in part — by $25 million from the state of New Jersey. While the city of Newark does maintain some manufacturing facilities, startups here can’t simply skip down to the massive Shenzhen markets to get a new part or have an old one machined. Instead, HAX has invested a lot into on-site equipment, including metal fab, 3D printing, CNC machines and laser and water jet cutters. There’s even a chemistry lab on-site for deep tech projects.

HAX will host its first demo day in four years here. The list includes more than 30 companies, across climate, manufacturing, computing, health and energy. We’ve got the exclusive list of all those companies showcasing (below).

Here are a few notable ones TechCrunch has chatted with over the years:

CocoonCarbon: U.K.-based CocoonCarbon has built a small factory inside a shipping container that is capable of turning steel runoff (turns out it’s called “slag”) into sustainable cement.

PureLi: Founded nearby, this Princeton University startup has designed a simple system it promises can dramatically speed up lithium extraction in brine lakes. Located primarily in South American countries like Chile, these “lakes” are produced when drilling for oil and gas. The startup is currently working on a rev share model, using a technology it says can double or triple the evaporation rate.

Renovate Robotics: We first covered this robotic roofing firm last March, when it announced a $2.5 million seed round. The news also found HAX associate/analyst Dylan Crow jumping to the startup side of the fence as COO. Renovate produced a winch-based robot that installs roof shingles in a gantry-like X,Y axis pattern. Roofing is an extremely dangerous business that’s prime for automation.

Silana: This Vienna firm is working on a robotic system that can completely automate the sewing process. Once completed, the startup says its technology (pictured at the top of the post) will be able to increase production speeds by 4x, while lowering costs and CO2 by 82% and 38%, respectively.

Swap Robotics: Swap has been around for a minute already. The firm actually competed in TechCrunch’s Startup Battlefield at Disrupt 2022. Founded in 2019, the company has built a robotic system designed to landscape solar farms — that means both grass cutting and snow removal. Early last year, the Battlefield finalist scored $7 million in seed funding. The round was fittingly led by California-based solar provider, SOLV Energy.

HAX’s Demo Day kicks off at 2 p.m. ET on May 1.
