Alt Carbon scores $12M seed to scale carbon removal in India
From a struggling family tea estate to an innovative climate venture, Alt Carbon has raised $12 million in a seed round as it plans to scale its carbon dioxide removal work in the South Asian nation. The climate tech startup, which locks away carbon for thousands of years through enhanced rock weathering on farmlands, attracted investment led by Lachy Groom, the co-founder of the robotics AI company Physical Intelligence.
The journey began in May 2020 with a bittersweet homecoming. Siblings Shrey and Sparsh Agarwal drove 16 hours from the eastern state of Kolkata to Darjeeling — a city known for tea farming in the leafy foothills of the Himalayas — expecting to bid farewell to their family’s tea estate, Salem Hill, which was facing bankruptcy. Instead, that farewell visit planted the seeds for Alt Carbon, which they officially launched in late 2023.
Initially, they explored carbon markets as a way to revive their family business and support other tea estates in the region by generating supplementary income. But during their exploration, they discovered enhanced rock weathering as an approach that could transform Darjeeling’s legacy from being at risk of climate change impact to a frontier of climate action.
“Within carbon markets, our realization was that a lot of the projects in India, which are more avoidance-based, are of very low quality, and they produce junk credits,” Sparsh said in an exclusive interview.
Last year, Alt Carbon started its pilot around the Agarwals’ family tea estate on about 500 acres of land, which they later scaled up in North Bengal, expanding their scope from tea farms to those of rice and bamboo. The startup aims to expand to 500,000 hectares of land.
By 2030, the startup aims to remove 5 million tons of carbon from the region, Sparsh told TechCrunch.

Alt Carbon deploys enhanced rock weathering using waste basalt rock dust from mines and quarries in the volcanic igneous province of Rajmahal Traps, located in eastern India. The rock dust, a waste product from the construction industry, is spread on farm fields, where it reacts naturally with rainwater to remove carbon dioxide and add micronutrients to the soil to improve its fertility and health and enhance crop yields. When rainwater containing carbon dioxide interacts with basalt dust, it forms stable bicarbonate ions. These are stored in the soil and eventually flow through rivers to the ocean, where they settle as calcium carbonate, locking away carbon for over 10,000 years.
For transporting the specialized dust from source locations to farm fields, the startup relies on rails and diesel trucks and pays for one-way fares as these sources are part of the tea industry’s freight transportation system. The startup also avoids emissions from dedicated rock processing by relying on the waste basalt from existing mining and crushing operations.
Instead of using the basalt dust alone, the startup has developed a proprietary combination of basalt and other organic ingredients, which it calls Hari Maati (green soil in Hindi), to convince farmers to spread it on their farmlands.
Alt Carbon estimates its carbon credits at $270 per metric ton, which Sparsh said is significantly cheaper than direct air capture credits that, he believes, cost roughly $800 a ton. However, he expects the startup to reduce costs within 36 to 48 months.
The startup relies on three layers of measurements to understand how much rock is getting weathered and how much carbon is being removed, Shrey told TechCrunch. It begins with measurements to track weathering progress and then moves to measuring water within the soil, groundwater sampling, and river monitoring. The third layer uses proprietary reactive transport models that help track ions transported from the soil to water bodies. The startup also uses machine learning-driven modeling to get carbon-removal numbers.
Alt Carbon says its models adhere closely to methodologies set by carbon removal registries, including Isometric and Puro.earth. They have also received approvals from intergovernmental organizations, including SBTi, ICVCM, and CORSIA.
The startup has its labs in Darjeeling and Bengaluru and employs 8 to 10 PhDs, with an overall headcount of 25 employees. It aims to scale these labs and expand its work by doing more soil sample analysis and even setting up a hardware studio for better, high-quality data collection on the ground, using remote sensing. The startup also plans to deploy sensors on the ground to get more insights at a lower cost and in a faster time. All this will come through that seed round led by Groom.
Last year, the startup secured a $500,000 pre-purchase by Frontier and a $1 billion advanced market commitment led by Stripe, Alphabet, Meta, Shopify, and McKinsey. It also recently signed a strategic partnership with a buyer coalition, NextGen, started by South Pole and Mitsubishi Corporation, to scale its enhanced rock weathering. The group also included BCG Group, Swiss RE, LGT, and UBS among its members. Last month, the startup signed an offtake agreement with Japan’s shipping company, MOL Group, to purchase 10,000 tons of carbon removal credits.
Alt Carbon will deliver its first carbon credits in less than a month through Isometric, Sparsh said.

The Case for Custom eLearning Platforms: Why Organizations Are Making the Switch
The corporate eLearning market has exploded in recent years, growing over 800% since 2000. As the demand for eLearning continues to accelerate, more and more organizations are finding that off-the-shelf solutions cannot keep pace with their training needs. This has led many companies to make the switch to custom-built eLearning platforms tailored specifically for their requirements.
There are several key reasons driving the demand for customized eLearning tools:
Greater Flexibility and Scalability
Generic eLearning software packages often impose rigid constraints that limit their ability to adapt to an organization’s evolving needs. Meanwhile, the “one-size-fits-all” approach fails to support the personalized learning critical for employee development. Custom platforms provide flexibility to add and modify features to match ever-changing business goals. As companies scale training across global workforces, custom solutions built on cloud infrastructure can scale seamlessly to handle growing demand.
Deeper Integration Across Systems
Smooth integration with existing HR, LMS, and other business systems is critical for optimizing training workflows. However, off-the-shelf tools rarely integrate well, creating data and process siloes. Custom platforms can tightly integrate role-based learning paths with core business applications, sync user profiles, enable single sign-on, and more. This level of integration catalyzes more impactful training function.
Better Data and Analytics
Generic software severely limits access to data insights that drive improvement. Custom platforms unlock a trove of analytics on content consumption, learner progression, platform adoption, and real-time feedback. Integrated analytics dashboards and APIs allow businesses to derive deep visibility across the learner lifecycle. These insights help continuously enhance learner experience, target development gaps, and demonstrate direct training ROI.
Enhanced Learner Engagement
For modern learners accustomed to consumer-grade digital experiences, poor platform usability quickly erodes engagement. Custom designs allow companies to incorporate familiar features from popular apps and websites while optimizing for their audience. Adaptive learning approaches further personalize content to individual styles and needs. With modular component architecture, custom platforms stay on the cutting edge of new modalities like AR/ VR to captivate learners.
Brand and Culture Alignment
Off-the-shelf tools impose a generic and often disruptive experience that clashes with existing brand identity and culture. In contrast, custom platforms allow organizations to carry over familiar styling, voice, and workflow patterns. Consistency in experience preserves brand recognition while smoother onboarding leads to wider adoption across all employee groups. Over time, the platform can evolve alongside cultural changes as well.
While custom elearning tools require greater upfront investment, for enterprise training needs, the long-term benefits far outweigh the costs. The ability to mold platforms to current and future needs results in greater leverage from learning spend.
As businesses demand ever-more from their learning technology, custom solutions provide the agility needed for true scale. Rather than forcing training functions into the constraints of generic software, custom elearning development keeps the focus on nurturing talent and capabilities. For any organization looking to drive workforce transformation through learning, custom elearning represents the way forward.

Pintarnya raises $16.7M to power jobs and financial services in Indonesia
Pintarnya, an Indonesian employment platform that goes beyond job matching by offering financial services along with full-time and side-gig opportunities, said it has raised a $16.7 million Series A round.
The funding was led by Square Peg with participation from existing investors Vertex Venture Southeast Asia & India and East Ventures.
Ghirish Pokardas, Nelly Nurmalasari, and Henry Hendrawan founded Pintarnya in 2022 to tackle two of the biggest challenges Indonesians face daily: earning enough and borrowing responsibly.
“Traditionally, mass workers in Indonesia find jobs offline through job fairs or word of mouth, with employers buried in paper applications and candidates rarely hearing back. For borrowing, their options are often limited to family/friend or predatory lenders with harsh collection practices,” Henry Hendrawan, co-founder of Pintarnya, told TechCrunch. “We digitize job matching with AI to make hiring faster and we provide workers with safer, healthier lending options — designed around what they can reasonably afford, rather than pushing them deeper into debt.”
Around 59% of Indonesia’s 150 million workforce is employed in the informal sector, highlighting the difficulties these workers encounter in accessing formal financial services because they lack verifiable income and official employment documentation.
Pintarnya tackles this challenge by partnering with asset-backed lenders to offer secured loans, using collateral such as gold, electronics, or vehicles, Hendrawan added.
Since its seed funding in 2022, the platform currently serves over 10 million job seeker users and 40,000 employers nationwide. Its revenue has increased almost fivefold year-over-year and expects to reach break-even by the end of the year, Hendrawn noted. Pintarnya primarily serves users aged 21 to 40, most of whom have a high school education or a diploma below university level. The startup aims to focus on this underserved segment, given the large population of blue-collar and informal workers in Indonesia.

“Through the journey of building employment services, we discovered that our users needed more than just jobs — they needed access to financial services that traditional banks couldn’t provide,” said Hendrawan. “We digitize job matching with AI to make hiring faster and we provide workers with safer, healthier lending options — designed around what they can reasonably afford, rather than pushing them deeper into debt.”

While Indonesia already has job platforms like JobStreet, Kalibrr, and Glints, these primarily cater to white-collar roles, which represent only a small portion of the workforce, according to Hendrawan. Pintarnya’s platform is designed specifically for blue-collar workers, offering tailored experiences such as quick-apply options for walk-in interviews, affordable e-learning on relevant skills, in-app opportunities for supplemental income, and seamless connections to financial services like loans.
The same trend is evident in Indonesia’s fintech sector, which similarly caters to white-collar or upper-middle-class consumers. Conventional credit scoring models for loans, which rely on steady monthly income and bank account activity, often leave blue-collar workers overlooked by existing fintech providers, Hendrawan explained.
When asked about which fintech services are most in demand, Hendrawan mentioned, “Given their employment status, lending is the most in-demand financial service for Pintarnya’s users today. We are planning to ‘graduate’ them to micro-savings and investments down the road through innovative products with our partners.”
The new funding will enable Pintarnya to strengthen its platform technology and broaden its financial service offerings through strategic partnerships. With most Indonesian workers employed in blue-collar and informal sectors, the co-founders see substantial growth opportunities in the local market. Leveraging their extensive experience in managing businesses across Southeast Asia, they are also open to exploring regional expansion when the timing is right.
“Our vision is for Pintarnya to be the everyday companion that empowers Indonesians to not only make ends meet today, but also plan, grow, and upgrade their lives tomorrow … In five years, we see Pintarnya as the go-to super app for Indonesia’s workers, not just for earning income, but as a trusted partner throughout their life journey,” Hendrawan said. “We want to be the first stop when someone is looking for work, a place that helps them upgrade their skills, and a reliable guide as they make financial decisions.”

OpenAI warns against SPVs and other ‘unauthorized’ investments
In a new blog post, OpenAI warns against “unauthorized opportunities to gain exposure to OpenAI through a variety of means,” including special purpose vehicles, known as SPVs.
“We urge you to be careful if you are contacted by a firm that purports to have access to OpenAI, including through the sale of an SPV interest with exposure to OpenAI equity,” the company writes. The blog post acknowledges that “not every offer of OpenAI equity […] is problematic” but says firms may be “attempting to circumvent our transfer restrictions.”
“If so, the sale will not be recognized and carry no economic value to you,” OpenAI says.
Investors have increasingly used SPVs (which pool money for one-off investments) as a way to buy into hot AI startups, prompting other VCs to criticize them as a vehicle for “tourist chumps.”
Business Insider reports that OpenAI isn’t the only major AI company looking to crack down on SPVs, with Anthropic reportedly telling Menlo Ventures it must use its own capital, not an SPV, to invest in an upcoming round.
