Teploy

• Managed platforms make deployment easy, but teams give up infrastructure ownership, flexibility, and cost control as they scale.
• Self-hosted tools give teams ownership, but provisioning, deployment state, HTTPS, rollback, monitoring, and provider management become operational burden.
• Deployment dashboards can drift from what is actually running on the server, especially when CLI, SSH, and web UI state are separate sources of truth.
• Observability is fragmented across analytics, APM, error tracking, and uptime tools, creating more services to integrate and pay for.
• The gap: cloud convenience without giving up server ownership.

Teploy is the company being funded. Developers get free deployment and observability tools; teams that need managed provisioning and operations — across infrastructure they still own — move to Teploy Cloud.

The raise — Teploy

Free: Neutron + Nucleus — one framework and one database covering what teams usually split across several specialized stores. The Teploy toolkit (CLI, Dash, Observe, and Ship, an autonomous coding agent) is what developers adopt first.

Paid: Teploy Cloud — provider aggregation, provisioning, and operations for teams that want ownership with less operational drag.

The proof — a built portfolio

Fylun — built and live in early access: an AI-native productivity suite running on the stack. Its builder, Fylun Studio, generates user sites on Neutron, so every site someone builds in Fylun is a live Neutron deployment — a second route to Neutron adoption beyond developers who pick it directly.

Tebian — built and live: a full operating system on GNU/Debian.

Infrastructure is the wedge; the portfolio is proof, not this round's focus. Long-term, the same design principle scales into a fully integrated stack — Teploy is where it starts monetizing.

The missing proof is intentionally clear: design partners, pilots, and first paid Teploy Cloud customers.

Teploy Cloud is the single paid product. The free stack — Neutron, Nucleus, and the Teploy toolkit — is what developers adopt and run themselves; Teploy Cloud is the upgrade for teams that want those operations managed, without giving up the servers underneath. The metric that matters is free-to-Cloud conversion.

Fylun and Tebian are optionality, not competing uses of capital — proof the same infrastructure holds up in production, with room to become their own line of business if either earns its own market.

Developer infrastructure is a proven, well-funded market — these outcomes are the size-of-prize proxy, not just comps: Vercel was valued at $9.3B in 2025, IBM acquired HashiCorp for $6.4B in 2025, and Netlify was valued at $2B in 2021. A platform with real developer adoption is venture-scale on its own. Teploy targets a narrower wedge inside it: teams that want cloud convenience while owning the underlying infrastructure.

Teploy's competitive field. Teploy sits between self-hosted deployment tools such as Dokploy, Coolify, and Kamal — where dashboard and server state can drift apart — managed platforms such as Heroku, Render, Railway, and Vercel, which trade ownership for convenience, and cloud-management products such as Cloudways. Observe consolidates into one self-hosted binary what teams usually buy as separate tools — error tracking (Sentry), product analytics (PostHog), web analytics (Plausible, Umami, GA4), and APM (SigNoz).

Why now. Smaller teams ship more software with fewer people, but infrastructure stays split across providers, dashboards, and monitoring tools. Teploy turns that operational surface into one open-core workflow.

One person designed and built every layer this company runs on — framework, database, deployment and observability toolkit, an autonomous coding agent, operating system, and a live AI product on top — as one system built to fit together, not separate tools bolted on. The throughline, earned across every product shipped: the infrastructure underneath is always the bottleneck, and Teploy is the company built to monetize the fix. The work today is deliberately narrow — Neutron and Teploy, the infrastructure this round funds; Fylun and Tebian are already shipped.

Range — Tebian

A free operating system on GNU/Debian with a guided setup menu — bare server up to containers, VMs, and security tooling. Proof the founder works at every layer, not just the parts customers see.

Rigor — Babel Bible

A curriculum that carries concepts from plain intuition up to fully verified Lean 4 proofs — the same exacting standard the founder brings to building the stack.

The capital is meant to buy validation time: design partners, pilots, first revenue, and a repeatable path to Cloud conversion.
