Attune

What do they actually do

Attune provides a drop-in build acceleration service. Developers swap their existing build command (for Rust, replacing cargo build) with Attune’s wrapper, which runs the build remotely and reuses previous outputs so repeated builds are faster. The service aims to deliver speed-ups without migrating to a new build system or rewriting build files, and it’s positioned as a one‑line change to existing workflows Attune homepage.

The product is live with a cloud‑managed Pro plan, an open/community edition on GitHub, and an Enterprise option that supports on‑prem installs and priority support. Pricing for Pro starts at $100/month with included build minutes; additional usage is billed by CPU/memory tier pricing, GitHub repo. Today, Rust is supported; Docker, CI runners (e.g., GitHub Actions), Swift, and Python are listed as “coming soon” Attune homepage. The team has shared demos claiming large build-time reductions during YC (e.g., 10 minutes → 26 seconds) YC Launch, LinkedIn demo.

Who are their target customer(s)

• Individual Rust developers (solo or small contributors): Slow local builds break focus and slow iteration. They want faster edit–build–test loops without learning or migrating to a new build system Attune homepage.
• Small engineering teams: They lose CI minutes and developer time to repeated builds and want quicker feedback with minimal setup and no build-config rewrites pricing.
• Platform/DevEx engineers: They need a broad, non‑invasive build speedup across many projects but can’t risk large migrations; it must work with existing commands and toolchains GitHub.
• Security- and compliance‑conscious organizations: They cannot send code/builds to third‑party clouds and need a self‑hosted or on‑prem option with enterprise support pricing.
• Teams relying on Docker or multiple languages: They face slow image builds and CI bottlenecks and want the same drop‑in caching/remote‑execution benefits for Docker and other languages (listed as coming) Attune homepage.

How would they acquire their first 10, 50, and 100 customers

• First 10: Founder‑led Rust pilots with YC demo respondents and active Rust contributors; hand-hold onboarding to swap cargo build for Attune, measure speedups, and gather quotes. Offer free credits and fast support to ensure successful installs Attune homepage, GitHub.
• First 50: Convert small teams via practical case studies and quick-start guides shared in Rust meetups, Discord/Slack, and GitHub threads. Provide a low-friction trial that minimizes CI minutes, plus referral credits for teams that bring in new projects.
• First 100: Target platform/DevEx and security‑sensitive orgs with self‑hosted trials and deployment playbooks; prioritize Docker and CI integrations so Attune fits existing pipelines. Run short enterprise trials with a clear migration checklist and use case studies to de‑risk procurement.

What is the rough total addressable market

Top-down context:

There are about 27M developers worldwide (2024) Evans Data. Third‑party reports place the CI/CD or continuous‑delivery market in the low single‑digit billions (e.g., ~$2.8B–$4.4B in 2024) MarketIntelo, Yahoo Finance/Astute Analytica, with high adoption indicated by the CD Foundation’s State of CI/CD CD Foundation.

Bottom-up calculation:

Seat model: If 1%–10% of the 27M developers adopt a $100/mo Pro seat, that’s 270k–2.7M seats → $324M–$3.24B ARR at list price Evans Data, Attune pricing. Enterprise model: Capturing 1%–5% of a ~$2.8B–$4.4B CI/CD market implies ~$28M–$220M ARR, depending on the baseline MarketIntelo, Yahoo Finance/Astute Analytica.

Assumptions:

• Only a minority of developers have build‑heavy workflows and would pay for acceleration; adoption scenarios (1%/5%/10%) illustrate range, not forecasts.
• The $100/mo Pro price and usage model remain representative at scale; discounts and overages will alter realized ARPA.
• Broader language/CI coverage is required to access most of the TAM; today’s reach is limited primarily to Rust and early adopters.

Who are some of their notable competitors

• sccache: A compiler cache for Rust and other languages that speeds repeated compilations by caching compiled outputs. It does not run full builds remotely or offer a managed remote‑execution service like Attune sccache.
• Bazel (remote caching/execution): A full build system with built‑in remote caching and execution. Powerful at scale, but typically requires adopting Bazel and rewriting build files rather than swapping a single command Bazel remote caching, remote execution.
• Gradle build cache / Gradle Enterprise: Speeds Gradle builds by reusing task outputs and, in enterprise editions, adds centralized cache servers and insights. Focused on the Gradle ecosystem, not a drop‑in for arbitrary build commands Gradle docs.
• Turborepo / Vercel Remote Caching: Remote cache for JavaScript/TypeScript monorepos that shares task outputs across machines and CI. Optimized for JS monorepos and repo‑level config rather than language‑agnostic command replacement Turborepo docs.
• BuildBuddy (enterprise RBE): Enterprise remote execution and caching (often via Bazel/RBE). Suits large orgs but usually expects Bazel/RBE‑compatible clients and more setup than a one‑line swap; Google’s RBE offers similar capabilities BuildBuddy, Google RBE.
