  • Why do 75% of AI agent tasks fail on basic business operations?
  • How does compound reliability math create structural demand for purpose-built primitives?
  • Which primitives (browser, search, memory, compute, payments) are growing fastest?

💎 Why It Matters

The bottleneck in AI shifted from intelligence to execution.


🔍 Problem

AI agents break when they touch the real world.

Each integration is custom, fragile and expensive.

More steps, more failure.


💡 Solution

Agent-first companies that build ready-made blocks for agents to operate in the real world.

One block per action: browse, email, pay, compute, remember, speak, search.


🏁 Players

Compute and Sandboxes

  • Daytona • Agent-first compute infrastructure with sub-30ms sandbox provisioning
  • E2B • Sandboxed cloud environments for agents
  • Agent Computer • Cloud virtual sandboxes with sub-second spin-up for persistent agent workloads

Browser Access

  • Browserbase • Headless browser infrastructure for agents
  • Browser Use • Open-source browser automation for agents
  • Hyperbrowser • Browser API with built-in scraping, session recording and agent orchestration

Search and Web

  • Exa • Neural search API built for agents
  • Firecrawl • Web crawling API converting any URL to LLM-ready data


🔮 Predictions

  • Cloud providers will acquire Agent-First startups as the category proves out. The pattern mirrors cloud-native acquisitions.
    • IBM spent $11B on Confluent to solve the “agentic AI puzzle”. Agent-First companies are natural next targets.
    • E2B has 88% of Fortune 100 signed up. Exa hit a $700M valuation. These are acquisition-ready assets.
    • AWS, Google and Microsoft all have agent infrastructure gaps that organic development won’t close fast enough.
  • MCP will become the de facto integration standard. It will commoditize connections and shift value to execution quality.
    • MCP grew from 100,000 downloads (Nov 2024) to 97M monthly SDK downloads by 2026.
    • Tens of thousands of MCP servers exist. A standardized plug doesn’t make all appliances equally good.
    • OpenAI, Google DeepMind and every major provider adopted it. The Linux Foundation accepted it as vendor-neutral.
  • Usage-based pricing will replace per-seat as the default for agent-adjacent software. Per-seat breaks when an agent does the work of 10 people.
    • Intercom already charges $0.99 per resolved issue instead of per seat.
    • Software companies anchored to seat counts will face margin compression as agents handle more work.
    • Every Agent-First company uses usage-based or per-API-call pricing. Browserbase bills by session minutes.


☁️ Opportunities

    • Launch an observability platform for multi-primitive agent workflows. When an agent uses browser, search, memory and email in one workflow, debugging has to check 4 dashboards.
      • This is the Datadog opportunity for agents. A single platform tracing execution across multiple primitives.
      • The compound reliability problem (85% per step = 20% success at 10 steps) makes end-to-end tracing essential at production scale.
      • Build an OpenTelemetry-compatible trace layer for agent workflows. Offer it free to Agent-First startups, upsell enterprises on the dashboard.
    • Ship an agent cost management platform. Usage-based pricing across a dozen providers creates a cost attribution problem that didn’t exist for human users.
      • The wedge: show teams what their agents actually cost per task. Own the billing data, own the optimization recommendations.
      • This is the CloudHealth opportunity for agent infrastructure: track per-workflow cost across providers, set budgets, alert on anomalies.
      • A single agent workflow might burn through sessions (Browserbase), search queries (Exa), memory calls (Mem0) and email sends (AgentMail). Each billed separately.
    • Build an identity and access management layer for AI agents. Every enterprise deploying agents needs to answer: who is this agent, what can it access, who authorized it?
      • AI leaders cite compliance and risk management as primary adoption barriers.
      • Current OAuth flows assume a human at a browser. No standalone company owns this layer and the compliance gap will widen as agent deployment scales.
      • The wedge: OAuth-compatible agent credentials. Start with companies already deploying agents (E2B’s Fortune 100 customers, Browserbase’s 1,000+ orgs).
    • Own vertical agent primitives for regulated industries. Current players build horizontal primitives. Healthcare, legal, financial services and real estate need domain-specific ones.
      • Start with one regulated industry where agent adoption is high and integration pain is acute.
      • Healthcare agents need HIPAA-compliant patient record access. Legal agents need court filing APIs. Financial agents need trading APIs with compliance controls.
      • Each vertical has regulatory requirements that horizontal providers will likely skip. The vertical player builds compliance once and sells to every agent in that industry.


    🏔️ Risks

    • Model Provider Bundling • OpenAI, Google and Anthropic could build agent primitives into their platforms, squeezing margins for standalone providers.
    • Integration Fatigue • Enterprises already drowning in APIs may refuse to add 5-10 more agent-specific vendors.
    • Regulatory Freeze • AI laws could slow enterprise agent deployment, shrinking demand for agent infrastructure across the board.
    • Pricing Volatility • Usage-based revenue is hard to predict, making enterprise procurement and investor valuation difficult.


    🔑 Key Lessons

    • The bottleneck shifted from intelligence to execution. Models can reason, plan and write code. The $52B opportunity is in making them act.
    • The execution gap widens as agents get smarter. Every leap in model capability increases demand for execution infrastructure. Agent-First companies are long the capability curve.
    • Usage-based pricing is on the rise but hybrid is the path to enterprise.Twilio, Stripe and AWS all navigated this transition. The playbook is well-documented.


    🔥 Hot Takes

    • The first company to reach $1B in revenue selling exclusively to AI agents (zero human customers) will come from this category.
    • “Agent Platform Team” will become a standard enterprise role within 3 years, mirroring the DevOps and Platform Engineering trajectory.
    • The real money in this space won’t be in primitives. It’ll be in the orchestration layer that stitches them together. Whoever builds the “Kubernetes for agents” captures the platform tax.


    😠 Haters

    “These are just APIs with a buzzword. What makes them ‘Agent-First’ instead of just APIs?”
    Agent-first companies are fundamentally different when the user is a machine instead of a human. Adding an MCP server to an existing API isn’t Agent-First. Rebuilding from scratch for non-human users is.

    “Agents don’t build habits or loyalty. They’ll switch providers with a config change.”
    True for commoditized connections. False for execution quality. Finding a provider that maintains 99.99%+ success rates at scale is hard. Switching costs live in reliability, not integration.

    “The more capable agents become, the larger the blast radius when something goes wrong.”
    This is the value of purpose-built blocks. They include guardrails: rate limits, spend caps, audit logs and human-in-the-loop checkpoints. The liability concern drives demand for exactly this infrastructure.
