The most widespread type of battery, lithium-ion, still costs around $140 per kilowatt-hour for a pack.
Instead, manufacturers have started to explore sodium-ion batteries, not as a replacement, but as a complement to lithium-ion.
To deliver that many batteries, Unigrid isn’t going to be building its own factories.
Small vehicles like these are popular in India and Southeast Asia, where the intense heat can make lithium-ion batteries prone to overheating.
To get its sodium-ion batteries into production, Unigrid has raised a $12 million Series A.
Wastewater from these plants emerges laden with sodium sulfate, a byproduct of sulfuric acid and caustic soda, two chemicals used in battery manufacturing, copper refining and other industries.
“We can totally create a circular economy around these reagent chemicals,” Bilen Akuzum, co-founder and CTO of Aepnus Technology, told TechCrunch.
The two founded Aepnus to modernize the century-old chloralkali process, which splits salts like sodium sulfate back into the acids and bases that created them.
“We don’t use any expensive catalysts in our electrolyzers,” Akuzum said.
For customers, fully recycling sodium sulfate waste should reduce disposal and material costs.
“We’ve got an increased threat from foreign adversaries who have shown capabilities to jam, to destroy, to spoof the signals of GPS, which is scary,” Shaun Moore, CEO and co-founder of Tern AI, a startup that wants to provide an alternative to GPS, told TechCrunch.
The current system works by having GPS receivers in cars or phones pick up signals from satellites orbiting the earth.
The GPS receivers then use the time it took for each signal to travel to calculate the distance to each satellite.
“GPS technology has not meaningfully changed in 50 years, and what we’re seeing put forth as solutions to resolve or mitigate risk are just marginal improvements.
“When we first met Tern AI, what stood out the most was how differentiated and scalable their approach was to solving a critical problem in national security,” said Stephen DiBartolomeo, principal at Scout Ventures.
Jordan Meyer and Mathew Dryhurst founded Spawning AI to create tools that help artists exert more control over how their works are used online.
Meyer claims that, despite the fact that it’s substantially smaller than some other generative AI training data sets out there, Source.Plus’ data set is already “high-quality” enough to train a state-of-the-art image-generating model.
Generative AI models “learn” to produce their outputs (e.g., photorealistic art) by training on a vast quantity of relevant data — images, in that case.
Image Credits: Spawning“Source.Plus isn’t just a repository for training data; it’s an enrichment platform with tools to support the training pipeline,” he continued.
And, Meyer says, Spawning might build its own generative AI models using data from the Source.Plus datasets.
When you’re looking for a startup idea that could slow climate change, you might become an expert at home energy assessments.
Instead, the startup has put together a small team of engineers to create its own AI model specialized in home energy assessments using machine learning.
The company uses open data, such as satellite images, as well as its own training data set with millions of photos and energy assessments.
In the company’s first tests, its home energy assessments have been accurate within 5% of old-fashioned assessments.
The startup has now raised €4.7 million ($5.1 million at today’s exchange rate) with Racine² leading the round and a non-dilutive investment from Bpifrance.
If death and taxes are inevitable, why are companies so prepared for taxes, but not for death?
In the immediate aftermath of Linder’s loss, founding a company would have been a long shot.
So Bereave built a B2B product to sell to employers, which they can offer their employees in times of need.
The platform catalogs resources for people experiencing loss, walking them through the steps of closing out a loved one’s affairs.
Tall Poppy, a company that offers digital safety guidance for employees navigating online harassment and hacks, also uses step-by-step checklists.
And like all productivity tools, the ClickUp team has also heard the siren song of artificial intelligence.
The company has now launched what it calls “ClickUp Knowledge Management,” which combines a new wiki-like editor and with a new AI system that can also bring in data from Google Drive, Dropbox, Confluence, Figma and other sources.
With that, the company aims to build a tool that can rival other popular services like Notion and Atlassian’s Confluence.
The result, ClickUp argues, is a system that brings together the best of Notion, Confluence and Glean to allow users to quickly create documents.
This now enables the ClickUp Knowledge Management to perform retrieval augmented generation (RAG) — which has quickly become the industry standard for augmenting large language models (LLMs) with additional and up-to-date information.
But e-bike subscription startup Whizz sees it as an opportunity.
The lack of disruption in the e-bike subscription arena could mean that Whizz is in a perfect position to get a first-mover advantage.
Or it could mean that the e-bike subscription model is difficult to get right.
Other consumer-facing micromobility subscriptions in NYC have come and gone, like Beyond’s e-scooter rental offering and charging infrastructure company Revel’s attempt at an e-bike subscription.
His co-founders — Alex Mironov, Ksenia Proka, and Artem Serbovka — built and sold an e-bike subscription platform, Moy Device, to a private equity firm in Russia.
It’s been more than a minute since Tesla went public, but the EV company was inescapable on TechCrunch this week.
From layoffs to pricing changes and more, it was a week dyed deeply in Tesla colors so we had to chat through the latest.
But that was just one element of what we got into on Equity this week.
We also dug into Mary Ann’s reporting about Ramp’s latest round — and up valuation — that fit neatly next to Rippling’s own impending fundraise.
Equity is back tomorrow with a special interview between Mary Ann and Notable Capital’s Hans Tung, so stay tuned!
Humans have cast metal parts in basically the same way for thousands of years: by pouring molten metal into a mold, often made of compacted sand and clay.
To make those parts, Magnus Metals borrows elements of sand casting and 3D printing to perform what it calls digital casting.
Magnus Metals plans to sell its machines to customers as well as the proprietary ceramic that’s used to produce the bases.
And unlike 3D printing, which usually requires specific feedstocks, Magnus Metals said its system can use customer specified materials.
The method doesn’t require expensive tooling to create the bases, unlike molds for sand casting, according to the Magnus Metals.
