Ulevel

What Ulevel does

Ulevel, operating as Tailf LLC, is a boutique platform engineering consultancy founded in 2015, operating from Belo Horizonte, Brazil with legal domicile in Cheyenne, Wyoming. The company delivers specialized consulting and managed services across Site Reliability Engineering (SRE), DevOps, Infrastructure as Code, Kubernetes orchestration, cloud engineering (AWS, Azure, GCP), and ML infrastructure provisioning. Its technology stack is Kubernetes-centric and cloud-agnostic, leveraging GitOps tooling (ArgoCD), observability (Prometheus, Grafana, Alertmanager), IaC (Terraform, Ansible, Helm), and GPU orchestration for ML workloads via the NVIDIA GPU Operator, Karpenter, and KEDA. The company also provides managed support for open-source AI/ML platforms including ComfyUI (Stable Diffusion workflows) and Comet Opik (LLM observability).

The firm monetizes through two streams: (1) professional services consulting delivered on a custom-engagement basis to enterprise clients, and (2) recurring managed services such as the Managed Prometheus Stack, publicly priced starting at $1,000/month with flat-fee billing and no cardinality limits. Named clients include Comet, Financial Times, CNH, Razorfish, and Anvil (YC), spanning financial services, media, agriculture, advertising technology, and startup segments. Target verticals include investment banks, financial institutions, cloud providers, streaming/media companies, and government entities with air-gapped or SOC 2 compliance requirements.

Ulevel is founder-owned and bootstrapped with no disclosed institutional funding. The company operates with two co-founders, Thales Ceolin and Fabricio Vieira, both with 20+ years of industry experience and CKA certification, delivering services through direct consultative sales via the company website, email, and LinkedIn. Go-to-market is exclusively direct with no channel partner or reseller model, and the firm's boutique positioning emphasizes specialized expertise over scale.

Revenue model

1. Platform Engineering Consulting Services: Professional services revenue generated from consulting engagements covering SRE, DevOps, Kubernetes implementation, cloud engineering, and infrastructure automation. Services are delivered through direct client engagements with enterprise organizations requiring specialized platform engineering expertise.
2. Managed Services: Recurring managed service revenue from Managed Prometheus Stack ($1,000/month starting price) and potentially other hosted offerings like Managed ComfyUI and Managed Opik. Client chooses between deploying on their infrastructure or ulevel-hosted fully managed instances.

Core offering

Ulevel is a boutique platform engineering consultancy providing SRE, DevOps, Kubernetes, and ML infrastructure services across AWS, Azure, and GCP. The company also sells recurring managed services (e.g., Managed Prometheus Stack) and open-source support services for ComfyUI and Comet Opik, helping enterprises build, operate, secure, and self-host cloud-native and AI/ML platforms.

Product overview

Ulevel is a boutique platform engineering partner offering specialized services rather than a unified software product. The portfolio consists of core platform engineering services (Cloud Engineering, Site Reliability Engineering, Kubernetes Services, and ML Infrastructure) augmented by specialized offerings (Managed Prometheus Stack, SaaS to On-Prem Deployments) and open-source support services (ComfyUI OSS Support and Comet Opik OSS Support). The core services provide cloud infrastructure management, SRE practices, Kubernetes cluster operations, and ML infrastructure provisioning, while the open-source support services specifically help clients deploy and manage ComfyUI for AI image/video generation and Comet Opik for LLM observability and evaluation.

Direct peers

• Jetstack: Jetstack is a Kubernetes-focused consultancy behind cert-manager and other CNCF projects, acquired by Venafi. Comparable as a specialist Kubernetes services firm working with regulated and enterprise customers on cert, security, and platform work.
• Replicated: Replicated provides tooling and services for SaaS vendors to deploy on-prem and air-gapped into enterprise environments. Directly comparable to Ulevel's SaaS-to-On-Prem service line and overlapping customer base (enterprise software vendors).
• Fairwinds: Fairwinds is a boutique Kubernetes platform engineering firm offering managed Kubernetes, GitOps, and cluster-hardening services to enterprises. Closest analog to Ulevel in team profile, open-source-first positioning, and Kubernetes-centric service catalog.

Emerging players

• Buoyant: Buoyant is the commercial sponsor of Linkerd, the CNCF service mesh, and provides enterprise support. Compares to Ulevel's open-source support service model (ComfyUI/Opik) and Kubernetes-native infrastructure focus.
• Plural: Plural is an open-source Kubernetes application deployment platform that automates cluster bring-up and GitOps workflows. Adjacent to Ulevel's Kubernetes and GitOps services, though delivered as a product rather than as a consultancy.
• Cast AI: Cast AI delivers Kubernetes cost optimization and autoscaling as a managed service. Adjacent to Ulevel's FinOps/cost-optimization and Karpenter-based autoscaling work, with a more productized delivery model.
• Loft Labs: Loft Labs (vCluster) provides Kubernetes virtualization and multi-tenancy tooling. Compares to Ulevel's Kubernetes management and platform-engineering offerings as an emerging productized alternative in the same space.
• Solo.io: Solo.io provides service mesh, API gateway, and Kubernetes-native networking tools (Istio, Envoy-based). Overlaps with Ulevel's Kubernetes platform and security-hardening work, particularly for regulated enterprise customers.

Broad incumbents

• Grafana Labs: Grafana Labs is the commercial steward of Grafana, Loki, Prometheus, and the LGTM stack. A natural incumbent against Ulevel's Managed Prometheus Stack offering, with broader product breadth and global scale.
• Sysdig: Sysdig is a broader cloud-native monitoring and security platform built on Prometheus and Falco. Competes indirectly with Ulevel's Managed Prometheus Stack and observability services, but offers a full SaaS suite rather than bespoke services.
