Armis Raises $435M in Pre-IPO Funding Round at $6.1B Valuation for Cybersecurity Growth

Armis, a San Francisco-based cybersecurity startup specializing in asset protection for enterprises, has secured a hefty $435 million pre-IPO funding round to fuel its expansion and pave the way for an expected IPO in 2026. The nine-year-old company – known for safeguarding critical infrastructure and IoT devices – saw its valuation jump to $6.1 billion with this round. The investment was led by Goldman Sachs’ Growth Equity arm, with participation from Alphabet’s CapitalG and Evolution Equity Partners. Armis reportedly turned down multiple acquisition offers (including a $5 billion bid from Thoma Bravo) in favor of this funding, underscoring its ambitions to remain independent and go public on its own terms.

Armis plans to use the fresh capital to accelerate product innovation and global go-to-market efforts as it marches toward $1 billion in annual recurring revenue (ARR). The company has already surpassed $300 million ARR this year and serves over 40% of the Fortune 100 among its customers. By “behaving like a public company” and hitting aggressive growth targets, Armis aims to become a multigenerational cybersecurity leader focused on unified cyber exposure management. The sizable pre-IPO round – coming just a year after a $200M raise at a $4.2B valuation – signifies strong investor confidence in Armis’ trajectory as it prepares for a potential late-2026 IPO.

Funding Details:

• Startup: Armis

• Investors: Goldman Sachs Alternatives (lead), CapitalG, Evolution Equity Partners (among others)

• Amount Raised: $435 million

Ripple Lands $500M in Funding at $40B Valuation to Build Out Crypto Banking Empire

Blockchain pioneer Ripple has landed a massive $500 million funding round that values the company at $40 billion, marking one of the year’s largest crypto financings. The raise was led by a cadre of Wall Street heavyweights – including Fortress Investment Group and Citadel Securities – with participation from major crypto investors like Pantera Capital, Galaxy Digital, Brevan Howard, and Marshall Wace. This strategic late-stage investment provides Ripple with a war chest to expand beyond its origins in cross-border payments and transform into a full-service crypto banking platform. It also signals growing institutional confidence in blockchain infrastructure, coming at a time of more favorable regulatory tailwinds for crypto ventures.

Founded in 2012 and known for the XRP cryptocurrency, Ripple has spent recent years diversifying its offerings through acquisitions and new products. The company now delivers services ranging from stablecoin issuance and crypto custody to prime brokerage and treasury management, effectively positioning itself as an institutional crypto bank. CEO Brad Garlinghouse noted that 2025 has been a “record year” as Ripple evolved into a crypto-native financial services provider. With six acquisitions completed in the past two years and this half-billion in fresh capital, Ripple is poised to accelerate its push into mainstream finance. The funding will bolster Ripple’s ability to compete with traditional financial institutions by providing blockchain-based alternatives for payments and banking, solidifying its status as one of the most valuable private companies in crypto.

Funding Details:

• Startup: Ripple

• Investors: Fortress Investment Group, Citadel Securities, Pantera Capital, Galaxy Digital, Brevan Howard, Marshall Wace

• Amount Raised: $500 million

MoEngage Secures $100M in Series F Funding to Accelerate AI-Powered Customer Engagement

Customer engagement platform MoEngage has secured $100 million in a Series F funding round aimed at fueling its global expansion and AI-driven product development. The new investment was co-led by India’s A91 Partners and existing backer Goldman Sachs Alternatives, and it values the San Francisco- and Bengaluru-based SaaS firm at roughly $700 million. As a marketing technology provider serving brands in 75+ countries, MoEngage plans to leverage the capital to deepen its presence in North America and Europe while enhancing its Merlin AI suite, which helps consumer brands automate personalized campaigns and product recommendations. This latest round (split 60% primary and 40% secondary) also brings MoEngage’s total funding to about $250 million to date, reflecting steady support from investors for its growth trajectory.

Founded in 2014, MoEngage spent its early years building a strong base in India and Southeast Asia before expanding aggressively into Western markets over the last few years. The platform enables business-to-consumer companies to harness their first-party customer data and engage users across web, mobile, and email channels with AI-optimized targeting. CEO Raviteja Dodda said the company’s focus on AI-powered decisioning – via features that automatically segment audiences, generate campaign content, and determine the best time and channel to reach customers – gives it an edge as marketers seek more efficient tools. MoEngage is on track to hit $100M in annual recurring revenue by the end of 2025, and this funding will help accelerate hiring and innovation to meet growing demand from enterprise clients around the world.

Funding Details:

• Startup: MoEngage

• Investors: A91 Partners (co-lead), Goldman Sachs Alternatives (co-lead)

Reevo Raises $80M in Funding to Build AI-Native Revenue Platform for Go-to-Market Teams

Reevo, an artificial intelligence startup aiming to overhaul enterprise go-to-market systems, has emerged from stealth with $80 million in funding for a go-to-market for teams. The Santa Clara-based company’s combined $10M seed and $70M Series A rounds were co-led by top Silicon Valley firms Khosla Ventures and Kleiner Perkins, giving Reevo a valuation of about $500 million.

Founded in 2024 by David Zhu (a former DoorDash engineering leader) and team, Reevo is developing a modern “AI-native” revenue operating system that unifies marketing, sales, and customer success tools into one intelligent platform. The goal is to replace the fragmented tangle of CRM, analytics, and outreach software that businesses use with a single, AI-driven platform that can automate workflows and provide end-to-end visibility into the customer journey.

Reevo’s platform consolidates every stage from initial prospecting to closing deals and post-sales support, allowing go-to-market teams to work from one source of truth. By embedding AI at its core, the system can automatically capture and analyze customer interactions (emails, meetings, etc.), generate insights, and even suggest next best actions for sales reps. This promises to eliminate the manual data entry and siloed processes that often slow down B2B revenue teams. The substantial funding, backed also by Zhu Ventures (Reevo’s co-founder’s fund), will be used to accelerate product development and hire top engineering talent as Reevo prepares to launch its platform commercially. With legendary investors like Vinod Khosla and Mamoon Hamid in its corner, Reevo aims to redefine how companies generate revenue by making their entire go-to-market stack smarter and more cohesive.

Funding Details:

• Startup: Reevo

• Investors: Khosla Ventures (co-lead), Kleiner Perkins (co-lead), Zhu Ventures

• Amount Raised: $80 million

• Total Raised: $80 million

• Funding Stage: Series A

Braveheart Bio Launches with $185M in Series A Funding to Tackle Heart Disease

Newly formed biotech Braveheart Bio has burst onto the scene with an impressive $185 million Series A financing to develop what it hopes will be a breakthrough treatment for a serious heart disease. The Boston-based startup formally launched on Nov. 5 with one of the largest first-round biotech fundings in recent memory. Its focus is a drug candidate (BHB-1893) for hypertrophic cardiomyopathy (HCM) – a condition where the heart muscle thickens abnormally – which Braveheart licensed from China’s Hengrui Pharmaceuticals in a deal earlier this year. Hengrui had already advanced the drug into Phase 2 and Phase 3 trials in China, and Braveheart will use the new capital to kick off global late-stage trials in 2026 to prove the therapy can be “best-in-class” against existing treatments. The sizable Series A indicates high conviction that Braveheart’s approach could challenge Bristol Myers Squibb’s Camzyos – currently the only approved HCM drug – by delivering better efficacy or safety for patients.

Braveheart Bio is led by CEO Travis Murdoch, the former head of an immunology startup acquired by Biogen, and its chairman is Biogen CEO Chris Viehbacher – bringing seasoned leadership to the young company. The startup’s investor syndicate features about half a dozen top-tier life science funds, among them Andreessen Horowitz (a16z), Forbion, and OrbiMed. With this strong backing, Braveheart intends to move quickly: the funding will support aggressive clinical development of BHB-1893 and build out the company’s operations. The broader strategy, as evidenced by Braveheart’s formation, is to scout promising drug assets globally (in this case from Hengrui in China) and develop them in the West – a model that has become increasingly common in biotech. Thanks to one of the year’s largest Series A rounds, Braveheart now has the resources to potentially bring a much-needed new therapy to HCM patients worldwide if its program succeeds in pivotal trials.

Funding Details:

• Startup: Braveheart Bio

• Investors: Andreessen Horowitz, Forbion, OrbiMed, and others

• Amount Raised: $185 million

• Total Raised: $185 million

• Funding Stage: Series A

• Funding Date: November 5, 2025

Giga Raises $61M in Series A Funding for AI Customer Support Automation

Giga, an artificial intelligence startup focused on customer support automation, has raised $61 million in a Series A round to expand its enterprise voice AI platform. Led by Redpoint Ventures with participation from Y Combinator and Nexus Venture Partners, the funding will help Giga scale its technology that enables companies to deploy AI-driven voice agents for customer service. Giga’s platform uses advanced natural language processing and contextual memory to hold realistic conversations with customers, aiming to reduce wait times and improve resolution rates. By training on a company’s own knowledge bases and data, Giga’s AI agents can understand nuanced inquiries and provide real-time assistance without needing human hand-offs, even in complex, compliance-heavy industries like finance and healthcare.

Founded by Varun Vummadi and Esha Manideep (graduates of IIT Kharagpur), Giga has already seen promising traction. Its AI support agents are handling millions of customer calls each month for large clients and have demonstrated success in deployments such as at DoorDash, where Giga’s solution reportedly reduced call escalations and sped up issue resolution. With the new capital, Giga plans to grow its technical team and accelerate go-to-market efforts, targeting global enterprises looking to transform their customer service operations with scalable AI. The substantial Series A round reflects investor conviction that voice AI can play a pivotal role in the future of customer support, augmenting or even replacing traditional call centers with always-on automated agents.

Funding Details:

• Startup: Giga

• Investors: Redpoint Ventures (lead), Y Combinator, Nexus Venture Partners

• Amount Raised: $61 million

• Total Raised: $61 million

• Funding Stage: Series A

Hearvana Raises $6M in Pre-Seed Funding to Develop On-Device AI for “Super­human” Hearing

Seattle-based Hearvana, founded by researchers at the University of Washington Mobile Intelligence Lab, including co-founder Shyam Gollakota, announced a $6 million pre-seed funding round on November 5, 2025. The startup is building an AI-powered sound enhancement platform intended to operate on-device and deliver advanced auditory capabilities such as noise-source localisation and adaptive sound “bubble” creation. In a world increasingly saturated with ambient noise, the startup’s pitch is that listening technologies should do more than just amplify—they should smartly differentiate and prioritise in real-time.

The round was led by Point72 Ventures and SCB 10X, with participation from the AI2 Incubator, SBI US Gateway Fund, Forston VC, Ascend, J4 Ventures, Pack Ventures, and Amazon’s Alexa Fund. The company will use the fresh capital to scale hardware partnerships (earbuds/hearing aids/smartphones), refine its on-device AI models for low-power environments, and build out commercial relationships with manufacturers and hearing-aid OEMs.

Funding Details:

• Startup: Hearvana

• Investors: Point72 Ventures (lead), SCB 10X, AI2 Incubator, SBI US Gateway Fund, Forston VC, Ascend, J4 Ventures, Pack Ventures, Amazon Alexa Fund

Tala Health Secures $100M in Seed Funding at $1.2B Valuation to Re-Imagine AI-Enabled Healthcare

Tala Health, a San Francisco-based health-tech startup incubated by Titan Holdings, closed a $100 million seed round on November 5, 2025, valuing the company at $1.2 billion. Tala Health’s vision is to combine AI automation with clinician oversight in a vertically integrated care platform: from symptom-checking and triage to referral and follow-up.

The startup argues that healthcare requires a proactive rather than reactive model, and AI can enable 24/7 engagement and earlier intervention. The new capital will fund the rapid scaling of its clinical AI model team, build partnerships with major payers/providers, and expand go-to-market in key U.S. geographies.

Funding Details:

• Startup: Tala Health

• Investors: Sofreh Capital (lead)

• Amount Raised: $100 million

• Total Raised: $100 million (seed)

• Funding Stage: Seed (with unicorn valuation)

• Funding Date: November 5, 2025

Crew Raises $3.8M in Seed Funding to Launch “Pre-Spend” Banking Platform

Lehi, Utah fintech startup Crew announced a $3.8 million seed funding round on November 5, 2025. The company was founded by former leaders of Divvy and offers a “budgeting before you spend” platform that integrates checking, savings, budgeting, and virtual cards for consumers.

Crew’s differentiator is its emphasis on proactive financial guidance: users plan a purchase, set aside funds (“pockets”), receive virtual cards, and track spending in real time — rather than the traditional model of tracking after the fact. The company reported a doubling of daily active users and card transactions in the past month. The new funds will support product enhancements, national rollout of its FDIC-insured checking (in partnership with Bangor Savings Bank), expansion of virtual card offerings, and compliance/stability build-out for scale.

Funding Details:

• Startup: Crew

• Investors: Capital Eleven (co-lead), Kickstart Fund (co-lead)

• Amount Raised: $3.8 million

• Total Raised: $6.3 million (includes prior $2.5 M pre-seed)
