Software thatholds under load.

Sablestack is a software engineering studio. We build and run custom software, the cloud platforms it ships on, and the AI inside and alongside it — from agents to custom models. One senior team, no handoffs.

Born in South Africa. Working worldwide.

02Capability

Built in layers,owned end to end

Each layer is built by the team that runs the one beneath it — one contract, no integration seams.

01layer—01

platform engineering
cloud migration
kubernetes — terraform
ci—cd — sre

Cloud & infrastructure

Platform engineering, cloud migration, and the pipelines that keep it shipping.

02layer—02

product engineering
apis — integrations
data layer — schemas
design systems

Software development

Custom software, end to end — schema to service to interface.

03layer—03

ai agents
rag — retrieval
llm fine—tuning
evals — guardrails

Applied AI

AI systems in production — agents, retrieval, and the custom models behind them.

03Process

Three phases,no handoffs

The team that writes the spec is the team that ships it. What each phase produces is listed, not implied.

Spec

A written, reviewable specification. Scope is a document, not a vibe.

Output

spec.md
architecture
estimate

Build

Weekly increments deployed to a shared environment from day one.

Output

shared environment
weekly increments
day—one deploy

Ship

Production cutover, runbooks, and a handover your team can operate.

Output

production cutover
runbooks
handover

04Position

From idea to production, nothing changes hands.

05Contact
