Capacity closed a Series E of more than $54M, bringing total funding past $159M, right after crossing $100M ARR in June — a 20x increase in 3.5 years. This is enterprises consolidating budgets from scattered point AI-support tools into a single platform, and Capacity is betting its unified 'train once, use everywhere' knowledge layer beats purpose-built, siloed agents.
Wonderful closed a $550M Series C led by Insight Partners, with Salesforce making its first investment in the company, at a $5B valuation — 2.5x its $2B Series B mark from less than six months ago. This is VCs betting on a unified enterprise-wide 'AI operating system' layer, rather than continuing to fund a pile of disconnected point agents.
Runable raised a $21M Series A co-led by Susquehanna Venture Capital and Nexus Venture Partners, at a $65M post-money valuation. The Bengaluru startup's agent doesn't just build your website or app — it also runs your ads, posts to social, and handles SEO, folding 'build' and 'grow' into a single agent.
Agent Platform uses a Cloudflare-first architecture: local `npm run dev` runs Node-based simulations, while production maps to Workers + Workers Assets + D1 + KV + R2 + Vectorize + Queues + Workflows + Durable Objects + Workers AI. The Runtime interfaces stay the same (InMemory → Cloudflare implementations), so upper layers migrate without noticing. Deployment requires only `wrangler login` → create resources → fill in IDs → `wrangler secret put` → `wrangler deploy`. CI/CD watches the main branch and runs typecheck + build + dry-run + migration + deploy.
Evaluation is Agent Platform's quality immune system: instead of collecting statistics only after a run, it enforces checks throughout Pre-run, In-run, and Post-run execution. Seven eval categories cover Flow → Step → Skill → Artifact → Evidence → Policy → Regression. A Skill release must pass five gates—Trigger, Functional, Policy, Regression, and Human Review—and any failure blocks it. The Learning Loop moves from Run signals through Proposal, Human Review, Sandbox Eval, Quality Gate, and Publish, under one strict rule: agents propose, humans review, and eval gates decide whether a change can ship.
Flow Runtime is the heart of Agent Platform: a Flow becomes immutable when published, each Run is bound to a specific version and preset, Steps move through a DAG according to edge conditions, every boundary saves a checkpoint, and resume/retry-step preserves the complete trace history.
Observability is a first-class capability, not logging added after the fact: a structured trace connects FlowRun→StepRun→SkillInvocation→ProviderCall→ToolInvocation→GuardResult→EvidenceItem→ArtifactVersion. The Evidence Store traces every claim back to its source, excerpt, citation, confidence, and conflicts. Artifact versioning supports approve/reject/regenerate without deleting history. Context Snapshots allocate token budgets by category and record automatic compression when a block exceeds its budget. Procedural, episodic, and semantic memory can be written only through proposals reviewed by a human.
Agent Platform turns AI agents from a blank chat window into a structured workflow platform whose behavior can be defined, versioned, observed, verified, and improved. Its built-in Deep Research seed flow demonstrates the complete feedback loop.
The Policy Engine acts as the Agent Platform's constitution and enforcement layer: policies are versioned and bound to flows and presets; four guard layers enforce rules at step boundaries; budgets cap cost, tokens, runtime, iterations, and tool calls; external writes require human approval; loop detection trips circuit breakers; and escalation records provide an auditable trail. Rules are configuration-driven, so adding one means changing JSON rather than hard-coded logic.
The Provider Router is Agent Platform's model and tool gateway: it unifies 30+ providers, MCP tool discovery, step-local permission control, fallback chains with RRF fusion, and an OpenAI-compatible Proxy that existing SDKs can use without code changes. It is configuration-driven rather than hard-coded, with provider-health-aware routing.
A Skill is a versioned, installable, and auditable capability package. Its dual-file architecture separates metadata from instructions, explicit binding replaces model-driven routing, and every invocation is recorded. The Learning Loop turns run signals into proposals, sandbox evaluations, human review, and publication while enforcing the principle: agents propose, humans review, and evals serve as the gate.
Not everyone should use a coding agent to modify code directly. AI Native teams need interface specs, test-first development, monorepo, security guardrails, human-in-the-loop, and token budget controls. Building an agent platform layer on top of coding agents and clearly redefining developer roles is the right path forward.
