WhatA managed build service specifically for Haskell projects that handles cross-compilation (ARM Mac to x64 Linux), static linking, dependency caching, and produces small deployment-ready binaries — eliminating the painful Docker-based build workflows.
SignalHaskell developers are frustrated that cross-compilation is effectively broken, static linking is a nightmare, Docker-based builds are painfully slow even with caching, and the whole experience is terrible compared to Go's seamless cross-compilation — and this is blocking adoption.
Why NowApple's ARM transition has made cross-compilation from dev machines to Linux servers a universal pain point; companies like Mercury proving Haskell works at scale are driving renewed interest; cloud build services (Depot, Namespace) have proven the managed-build model works.
MarketNiche but high-value: ~5,000-10,000 professional Haskell developers and their companies willing to pay $50-500/mo; adjacent Rust/OCaml communities expand TAM; competes with DIY Docker setups and generic CI — no Haskell-specific solution exists.
MoatDeep Haskell/GHC toolchain expertise is rare and hard to replicate; accumulated dependency cache across customers reduces build times for everyone (shared cache network effect).

Haptic Feedback Layer for Automotive TouchscreensC6/10A screen-overlay or software-hardware module that adds precise tactile feedback and raised-edge zones to existing car touchscreens, making them usable without looking.
Automotive UX Testing Platform with Driver Safety MetricsC7/10A SaaS platform that lets automakers test infotainment designs with real drivers, measuring eyes-off-road time, task completion errors, and cognitive load before committing to production.
Observable-by-Default API Client SDK PlatformP6/10A platform that generates fully instrumented, observable API client libraries for third-party services — with built-in tracing, timeout controls, and fault injection — so engineering teams don't have to write their own.
Type-Driven Authorization Middleware for Web AppsP5/10A language-agnostic middleware and code-generation tool that enforces authorization state transitions (anonymous → authenticated → access-controlled) through the type system, making auth bugs impossible to compile.
Personal Finance OS With Programmatic Account ControlC7/10A personal banking layer (or Mercury-like neobank for consumers) that lets individuals create unlimited named sub-accounts, per-category virtual cards, automatic allocation rules, and a full API for programmatic access and plaintext accounting sync.
