Discover the measurable impacts of AI agents for customer support

How Did Papaya Slash Support Costs Without Adding Headcount?

When Papaya saw support tickets surge, they faced a tough choice: hire more agents or risk slower service. Instead, they found a third option—one that scaled their support without scaling their team.

The secret? An AI-powered support agent from Maven AGI that started resolving customer inquiries on day one.

With Maven AGI, Papaya now handles 90% of inquiries automatically - cutting costs in half while improving response times and customer satisfaction. No more rigid decision trees. No more endless manual upkeep. Just fast, accurate answers at scale.

The best part? Their human team is free to focus on the complex, high-value issues that matter most.

You saw the headlines. You maybe even hit shared it with a friend. But do you actually know what’s under the hood?

Welcome to Inside the Round, where we peel back the hype, follow the money trail, and show you the signals hiding in plain sight.

Let’s dive in!

The Deal:

Anthropic, raised $13 billion in Series F funding at a $183B valuation.

  • Lead Investor: ICONIQ

  • Co-Leads: Fidelity Management & Research, Lightspeed Venture Partners

  • Other Investors: Altimeter, Baillie Gifford, BlackRock, Blackstone, Coatue, General Atlantic, General Catalyst, Goldman Sachs, Insight, Jane Street, T. Rowe Price, QIA, OTPP, and more

This is one of the largest private rounds in tech history. It positions Anthropic as OpenAI’s most serious rival.

What Do They Actually Do?:

Anthropic is the company behind Claude, the frontier model series now powering enterprises, startups, and power users worldwide.

  • Claude AI: Trusted for reliability, safety, and alignment

  • Claude Code: Already at $500M+ run-rate revenue just months after launch

  • Enterprise Platform: Over 300,000 business customers, with large accounts growing nearly 7x in the past year

  • Consumer Plans: Claude Pro and Max give power users advanced model access

Anthropic’s edge: not just raw capability, but alignment and interpretability baked into the core of their models.

The Growth Story

The numbers are staggering:

  • March 2023: Claude launched

  • January 2025: $1B run-rate revenue

  • August 2025: $5B+ run-rate revenue

  • 300K+ businesses actively using the platform

This makes Anthropic one of the fastest-growing tech companies ever.

The Founders

  • Dario Amodei (CEO) – Former VP of Research at OpenAI, now leading Anthropic’s push into frontier AI

  • Daniela Amodei (President) – Former OpenAI People & Safety lead, co-founder focused on scaling responsibly

  • Team: Built around ex-OpenAI researchers, with a reputation for both technical excellence and safety-first research

Anthropic’s DNA is a mix of deep technical chops and a mission-driven approach to AI alignment.

Why Now?

GTM execution is changing fast.

  • AI is automating manual tasks across sales and marketing.

  • GTM teams are becoming more technical.

  • Legacy CRMs are too slow, rigid, and complex. Seriously no one likes their CRM.
    Attio is all in on programmable CRM, betting that forward-thinking teams want tools that evolve with them.

Competitive Context

Anthropic is going head-to-head with:

  • OpenAI: Consumer dominance with ChatGPT, strong enterprise momentum

  • Google DeepMind / Gemini: Backed by Alphabet’s compute, but slower GTM motion

  • Mistral: Europe’s rising open-weight model challenger

  • xAI: Musk-backed, noisy but still catching up in enterprise traction

Anthropic’s differentiation: trusted, reliable, and safety-led AI. Where others are chasing scale, Anthropic is selling confidence.

Mini SWOT Analysis

Strengths

  • $5B+ run-rate revenue with enterprise-heavy base

  • Best-in-class alignment and interpretability research (Constitutional AI)

  • Strong backers and strategic investors

  • Growing developer adoption with Claude Code

Weaknesses

  • Consumer mindshare lags behind ChatGPT

  • Valuation expectations are sky-high

  • Heavy dependence on hyperscaler partnerships for compute

Opportunities

  • Win government and regulated industry contracts (finance, healthcare, defense)

  • Expand developer ecosystem around Claude Code and APIs

  • Leverage safety reputation to become the default enterprise AI choice

Threats

  • Competitive breakthroughs from OpenAI, Google, or open-source challengers

  • Regulatory scrutiny as a “safety-first” company if failures occur

  • Risk of spreading too thin across enterprise, developer, and consumer segments

What Could Kill This Company?

If Anthropic fails to translate its safety-first edge into clear enterprise dominance, it risks being overshadowed by OpenAI’s consumer moat or Google’s infrastructure firepower.

With $183B valuation pressure, even slight growth misses could be costly.

Final Takeaway

Anthropic just raised one of the largest private rounds in history to prove that safety and scale can coexist. If they succeed, Claude could become the backbone of enterprise AI worldwide. If they stumble, they risk becoming a very expensive “second place” in the frontier model race.
