Arc Boats designs and manufactures electric boats and electric propulsion systems for consumer, commercial, and defense customers. The company sells consumer sport boats that currently generate meaningful revenue while using that product line to validate its technology for commercial buyers. For commercial projects Arc typically designs boats for customers and partners with shipyards to build them, exemplified by a hybrid tugboat developed for Curtin Maritime with Snow & Co. For defense customers Arc intends to supply propulsion systems directly to primes and neo-primes to meet demand for more reliable, electric powertrains. Arc has grown to about 200 employees and plans to add production, engineering, and go-to-market staff following its latest fundraise.

Nitra embeds AI agents into core business functions—payments, procurement, inventory management, scheduling, and insurance verification—giving medical practices a single system to run their back office. Its financial suite includes a Visa-powered expense card, bill pay, patient payment processing, and AI-driven accounting, while its commerce marketplace connects users to thousands of biopharma and medical-supply products through partners like McKesson and Medline. Recently the company added a voice-AI patient management module that handles appointment scheduling and insurance eligibility checks. In 2025 the platform’s annualized revenue jumped from $4 million to more than $33 million on 740 percent growth, and it surpassed $1 billion in annualized processing volume across thousands of doctors in over 700 clinics. December 2025 saw a single-day record of roughly $9 million in purchases. Management expects to serve 3,000+ clinics, top $150 million in annualized revenue, and exceed $4 billion in processing volume during 2026. Founded in 2024 by CEO Tim Hwang and President Jonathan Chen, Nitra plans to expand headcount from about 50 to over 200 and roll out new AI modules for revenue-cycle management, patient marketing, payroll, and staffing.

Verustruct develops robotic systems and a software suite to automate housebuilding, centered on a patented translational slip form (TSF) technology that can extrude load-bearing walls onsite while integrating electrical, plumbing, and insulation. The company applies machine learning and real-time inspection software to accelerate construction workflows and produce higher-quality builds. It targets lower-cost materials such as basalt and limestone to reduce per-square-meter building costs. Verustruct was founded by Nicholas Callegari, then an MBA student at the Yale School of Management, and received strategic support from that school during its early development. The company converted to a Public Benefit Corporation to embed social objectives alongside venture growth. Verustruct has publicly disclosed an oversubscribed $2.4 million pre-seed raise to advance its technology and operations.

Copper, led by CEO Sam Calisch, is a Berkeley, CA-based appliances company focused on improving electrification. Its first product is a battery-equipped induction stove that plugs into a regular 120V outlet. The stove enables cooks to upgrade from gas to induction without costly, complex electrical upgrades. The company raised $28M in funding. Copper intends to use the funds to continue to scale its technology platform into additional products. The round was led by Prelude Ventures and included participation from Building Ventures, Voyager, Collaborative Fund, Climactic, Designer Fund, Necessary Ventures, Leap Forward Ventures and Climate Capital. Channing St. Copper’s core product is an Energy Storage Enabled (ESE) induction stove that embeds a modest battery into the appliance to deliver high-performance induction cooking on a normal (120V) outlet, avoiding 240V wiring. The stove includes load-shifting capabilities designed to work with power utilities and to create a network of energy-storage-enabled appliances that plug into standard outlets. Embedding batteries into appliances is intended to eliminate permitting, wiring complexity, and labor costs associated with whole-home battery installs, and to lower the installed cost and installation barriers compared with systems like the Tesla Powerwall. The company positions the product as a fast, cheap pathway to retire gas ranges (the article cites 45 million gas ranges in use) and to reduce greenhouse gas emissions while improving public health and safety. Channing St. Copper plans to expand its offering toward whole-home electrification with a suite of ESE appliances including hot water heaters, mini-split/heat-pump air conditioners, and clothes dryers. The LinkedIn post congratulates Eric Wilhelm, Sam Calisch, and the Channing St. Copper team for the milestone.
