Cerenovus
Cerenovus
AI operating partner that reads enterprise records to surface hidden inefficiencies and warn about breaking systems, every claim cited.
Key features
- Cited Findings: Every claim opens downward to the original document — a quote that cannot be found in its source never enters the record, so audit and legal can trust each line.
- Inefficiency Detection: Surfaces duplicate payments, missed discounts, zombie software seats, dormant vendors, stalled receivables, and process patterns that quietly drain margin.
- Early-warning Signals: Flags promises past deadline with no fulfilling event, accounts whose rhythm broke, renewals about to close at last year's usage, and processes that stopped running.
- Time-aware Ledger: Answers what was believed vs what was actually true at any past date, so last quarter's company is still queryable — critical for audits and post-mortems.
- Independent Review Loop: Every finding is checked against its sources before it reaches the user; anything unresolved goes to a human reviewer instead of being silently dropped.
- Numbers With Workings: Each figure ships with the calculation and the source documents behind it, so any line can be rerun, checked, or opened for evidence.
- Zero-install Ingestion: Reads the records a company already produces with no installation and no user interviews required.
- Segmented Solutions: Purpose-built jobs for Enterprise, Middle Market, Private Equity, Consulting, Secondaries/Continuation Vehicles, and Corporate M&A/Integration teams.
Best for
- Margin Recovery Sweeps: Find duplicate vendor payments, missed early-pay discounts, and idle SaaS seats in weeks-of-history without a consulting engagement.
- Process Bottleneck Discovery: Identify approval chains that reject nothing but add weeks, or work items that always route through one bottleneck person.
- Executive Early Warning: Give CEOs, CFOs, and COOs a standing early-warning system so problems reach them while they're still small and cheap to fix.
- Deal-side Due Diligence: PE, M&A, and integration teams can query years of a target's records for hidden risk with every claim cited to the source document.
- Consulting Delivery Acceleration: Advisory firms use Cerenovus as their inspection layer so questions that used to take weeks of digging get an evidence-backed answer in minutes.
- Complex Exit Support: Secondaries and continuation-vehicle sponsors get a time-aware record they can defend to LPs and auditors.

CubeSandbox
TencentCloud
Open-source, hardware-isolated sandbox service for AI agents — sub-60ms cold start, <5MB overhead, E2B-SDK compatible.
Key features
- Sub-60ms Cold Start: Average <60ms boot time and <5MB memory overhead per instance, so a single node can run thousands of agents.
- Hardware-Level Isolation: Each sandbox gets its own Guest OS kernel on RustVMM/KVM — no Docker shared-kernel escape surface for LLM-generated code.
- E2B SDK Compatibility: Drop-in replacement for the E2B SDK — swap one URL env var and existing agent code runs unchanged.
- AutoPause / AutoResume: Idle sandboxes automatically suspend and wake on the next request for aggressive cost optimization.
- Snapshot, Clone & Rollback: CubeCoW copy-on-write engine takes 100ms-granularity checkpoints so agents can fork, roll back, or replay any saved state.
- Credential Vault: Agents call LLMs and external APIs through a proxy — keys never enter the sandbox, model context or logs.
- Egress Control: Per-sandbox domain allowlists with instant block on unauthorized egress and full audit logs for compliance.
- Web Console & Templates: In-browser dashboard at :12088 for managing sandboxes, nodes, version matrix and OCI-image-based templates.
Best for
- Running Untrusted LLM Code: Execute Python/shell that a model wrote without risking the host through hardware isolation.
- E2B Migration: Move existing E2B-based agent workloads to on-prem/self-hosted infrastructure with zero code changes.
- High-Density Agent Fleets: Host thousands of concurrent agent sandboxes on a single node thanks to sub-60ms boot and 5MB overhead.
- Agent Snapshotting: Save state before a risky tool call and roll back on failure using CubeCoW snapshots.
- Compliance-Sensitive Agents: Enforce egress domain allowlists and audit logs for regulated environments.
- Self-Hosted Agent Infra: Deploy a multi-node cluster with the built-in Terraform module for private-cloud AI agent workloads.
