Crusoe Energy Systems Powers AI Future with $1.38 Billion Series E at $10 Billion Valuation

Fund Raised: $1.38 billion

Investors: Valor Equity Partners (co-lead), Mubadala Capital (co-lead), NVIDIA, Fidelity Management, Founders Fund, Tiger Global, Salesforce Ventures, Franklin Templeton

Denver-based Crusoe Energy Systems closed a massive $1.38 billion Series E round, achieving a $10 billion valuation and positioning itself as one of the most capitalized players in AI infrastructure. Founded in 2018 by Chase Lochmiller (former hedge fund quant) and Cully Cavness, Crusoe has transformed from a cryptocurrency mining operation powered by stranded natural gas into a critical enabler of the AI revolution.

The company’s vertically integrated approach controls the entire stack—from energy generation to data center construction to cloud compute delivery. This model has allowed Crusoe to build faster than traditional operators, recently bringing online the first phase of its 1.2-gigawatt campus in Abilene, Texas, just one year after breaking ground. The facility, developed for OpenAI and Oracle as part of the Stargate project, represents the largest AI-focused data center deployment to date.

Crusoe differentiates itself through its energy-first strategy. The company sources power through an “all-of-the-above” mix including solar, wind, hydro, geothermal, and natural gas, often pairing on-site turbines with battery storage. In Iceland, Crusoe operates on 100% geothermal power through partner atNorth. The company reports a 45-gigawatt development pipeline—equivalent to powering eight to ten New York Cities.

As AI electricity demand rises faster than U.S. grid capacity, Crusoe’s expertise in managing stranded energy sources gives it a unique competitive edge. The company recently signed an agreement with GE Vernova to supply 29 aeroderivative gas turbines for flexible on-site generation. Crusoe Cloud, the company’s GPU-optimized compute platform, serves leading AI startups including Cursor, Decart, Fireworks, Odyssey, and Together AI, with bookings growing 5x in the first three quarters of 2025.

The funding brings Crusoe’s total equity raised to approximately $3.9 billion, with an additional $10 billion debt package arranged through JPMorgan and Blue Owl Capital, secured by Oracle’s 15-year Abilene lease.

Uniphore Secures $260 Million Series F from Tech Giants for Business AI Platform

Fund Raised: $260 million

Valuation: $2.5 billionInvestors: NVIDIA, AMD, Snowflake, Databricks Ventures (co-leads), NEA, March Capital, BNF Capital, National Grid Partners, Prosperity7 Ventures

Palo Alto-based Uniphore closed a remarkable $260 million Series F round led by four of the world’s top AI and data infrastructure companies—NVIDIA, AMD, Snowflake, and Databricks—marking an unprecedented validation of the company’s position in enterprise AI.

This positioning in the AI stack—between model providers and end applications—has proven increasingly valuable as companies rush to implement generative AI features.

Sesame Raises $250 Million to Build Voice-First AI Smart Glasses

Fund Raised: $250 million

Total Funding: $307.6 millionInvestors: Sequoia Capital (lead), Spark Capital (lead)

San Francisco-based Sesame secured $250 million in Series B funding while simultaneously launching its beta program, positioning the startup to compete with Meta and other tech giants in the emerging smart glasses market. Founded by Oculus co-founder and former CEO Brendan Iribe, former Ubiquity6 CTO Ankit Kumar, and former Meta Reality Labs director Ryan Brown, Sesame brings formidable hardware expertise to the wearable AI space.

The company is developing lightweight smart glasses integrated with advanced conversational AI that responds to natural speech. Unlike existing voice assistants that feel transactional, Sesame’s AI—featuring voices named “Maya” and “Miles”—captures the rhythm, emotion, and expressiveness of real human dialogue. When the company emerged from stealth in February, over one million people accessed the demos within weeks, generating more than five million minutes of conversation.

Sesame’s founding team reads like an Oculus reunion. Beyond the three founders, the roster includes Oculus co-founder Nate Mitchell as Chief Product Officer, former Oculus and Fitbit COO Hans Hartmann managing operations, and longtime Facebook and Meta executive Angela Gayles. This hardware execution experience matters enormously in a space where Amazon’s Echo Frames flopped and Google Glass became a cautionary tale.

The beta launch strategy reveals Sesame’s confidence in their technology. Starting October 21, select iOS users can access an early version of the AI companion through a dedicated app. The company also released its base AI model, CSM-1B, a 1-billion-parameter model available under an Apache 2.0 license for commercial use.

Sequoia Capital described the investment as a bet on voice becoming the next dominant computing interface, following the evolution from typing to tapping. “Sesame’s conversational layer felt different. It doesn’t just translate LLM output into audio—it generates speech directly, capturing the rhythm, emotion, and expressiveness of real dialogue.”

Moniepoint Closes $200 Million Series C to Scale African Fintech Leadership

Fund Raised: $200 million (including $90 million extension)

Valuation: Over $1 billion (unicorn status maintained)Investors: Development Partners International (lead), LeapFrog Investments, Google Africa Investment Fund, Visa, International Finance Corporation, Proparco, Swedfund, Verod Capital Management, Lightrock, Alder Tree Investments

Nigerian fintech Moniepoint closed its Series C round at $200 million after raising an additional $90 million extension, marking one of Africa’s largest fintech fundraises in 2025. Founded in 2015 by Tosin Eniolorunda and Felix Ike as TeamApt, Moniepoint has evolved from building payment infrastructure for banks into a comprehensive financial platform serving over 10 million active customers.

What sets Moniepoint apart from other African fintech unicorns is its profitability. The company claims to be the first African fintech to achieve profitability at unicorn scale while maintaining hypergrowth—processing over $250 billion in digital payments annually with revenue growing at over 150% CAGR. This combination of scale, growth, and profitability makes it an outlier in the African fintech ecosystem.

Moniepoint initially gained recognition through its agency banking network, bringing financial services to millions of underserved Nigerians. The company has since expanded into business and personal banking, credit, cross-border payments, and business management tools. Recent product launches include MonieWorld, a remittance solution targeting the African diaspora in the United Kingdom, and an integrated payment and bookkeeping platform for MSMEs.

The company processes 1 billion transactions monthly worth $22 billion—a 25% increase in just three months following its initial Series C close in October 2024. This momentum demonstrates the massive opportunity in Africa’s digital payments landscape, where cash remains predominant and traditional banks underserve small businesses.

Visa’s participation is particularly notable as the global payments giant deepens its involvement with Africa’s leading fintechs. Beyond Moniepoint, Visa has backed Interswitch, Paystack, and Flutterwave, while launching a fintech accelerator program across the continent.

The fresh capital will support Moniepoint’s expansion into at least five African countries over the next 18-24 months, starting with Kenya, while strengthening its UK operations. Despite reporting a $1.2 million loss in its first year of UK operations, the company remains well-positioned with backing from global investors.

LangChain’s framework solved this pressing problem, and developer adoption skyrocketed. The company raised a $10 million seed led by Benchmark in April 2023 and a $25 million Series A in 2024 at a $200 million valuation.

The market has grown increasingly crowded with competitors like LlamaIndex and Haystack, while OpenAI, Anthropic, and Google now provide built-in capabilities that were once LangChain’s differentiators. However, the company has evolved beyond its initial framework to build multiple products that enterprises need for production AI deployments.

Anrok Closes $55 Million Series C to Automate Global Sales Tax Compliance

Fund Raised: $55 million

Investors: Sequoia Capital, Index Ventures, Bessemer Venture Partners

San Francisco-based Anrok secured $55 million in Series C funding to scale its automated sales tax compliance platform globally. As businesses expand internationally and navigate increasingly complex tax jurisdictions, Anrok’s AI-powered system automatically determines tax obligations, calculates rates, and files returns across multiple countries.

The company solves a critical pain point for fast-growing technology companies. Traditional tax compliance requires dedicated finance teams monitoring regulatory changes across thousands of jurisdictions, manually calculating obligations, and filing returns. For companies selling digital products and services globally, this complexity multiplies exponentially.

Anrok’s platform integrates directly with billing systems, ERPs, and payment processors to automatically handle tax compliance end-to-end. The system continuously monitors regulatory changes across jurisdictions and adjusts calculations in real-time, reducing the risk of non-compliance penalties while freeing finance teams to focus on strategic work.

The Series C funding will support Anrok’s international expansion, particularly in European markets where digital services taxes and VAT regulations create significant complexity for U.S. companies. The company will also expand its product capabilities to cover additional tax types beyond sales tax, including indirect taxes and customs duties.

Findem Secures $51 Million to Transform AI-Powered Talent Acquisition

Fund Raised: $51 million ($36M Series C + $15M growth loan)

Investors: Silver Lake Waterman (lead), Wing Venture Capital, Harmony Capital, Four Rivers Group, JPMorgan (growth loan provider)

Redwood City-based Findem raised $51 million in combined equity and debt financing to expand its AI-powered talent acquisition platform. The company uses “3D talent data” compiled from trillions of data points to help enterprises identify and engage top candidates, differentiating itself from traditional recruiting tools that rely on resume keywords and LinkedIn profiles.

Founded in 2019, Findem has built proprietary datasets that map candidates’ skills, experience, and career trajectories in granular detail. The platform’s AI models predict candidate fit, likelihood to move, and compensation expectations, enabling recruiters to build more targeted pipelines and reduce time-to-hire.

The funding reflects growing demand for AI-native recruiting solutions as companies face talent shortages in competitive markets. Traditional recruiting workflows—posting jobs and waiting for applications—increasingly fail to surface the best candidates, who are often passive and not actively job searching.

Findem’s platform continuously scans and updates talent profiles, alerting recruiters when candidates become more likely to consider new opportunities based on career milestones, company events, or market changes. This proactive approach transforms recruiting from reactive application screening to strategic talent sourcing.

The $15 million growth loan from JPMorgan provides additional flexibility for customer acquisition and product development, while the $36 million Series C equity round, led by Silver Lake Waterman, will fuel expansion into new markets and customer segments.
