Company profile
researched Aug 2026LoopPerfect is a developer-tools company that describes itself as building software for C and C++ engineers. Its principal product is Buckaroo, a package manager for C/C++ that lets developers add third-party modules to a project in a controlled, cross-platform way. Buckaroo packages are built with Buck build, which the company states delivers fast and reproducible builds (source 1). The project is described on the company's GitHub organization as "the decentralized package manager for C++ and friends" (source 2).
Beyond Buckaroo, the LoopPerfect GitHub organization hosts a set of open-source C++ libraries and tooling, including neither (Either and Maybe monads for error handling), valuable (a smart pointer with value semantics), conduit (coroutine-TS-based high-performance streams), rxterm (functional reactive terminals), a Homebrew tap for installing Buckaroo, a Visual Studio to Bazel project converter, Skylark packaging utilities, a Buckaroo package-request wishlist repo, and archived Buckaroo documentation. Repositories are largely MIT-licensed; the organization lists 23 repositories in total (source 2).
At Entrepreneur First's sixth demo day in London in September 2016, the company (listed as "Loop Perfect") presented a different framing of its mission: streamlining C++ development using a just-in-time compiler that allows a user to update program logic without closing the running application (source 5). The company appears in the Entrepreneur First portfolio directory (source 4).
Founding story
LoopPerfect emerged from Entrepreneur First, a London-based "talent first" investor that recruits technical founders pre-team and pre-idea and puts them through a six-month programme that includes a living stipend, GBP 10,000 in pre-seed funding, office space, and legal, administrative and mentoring support. The company was among the 21 teams that presented at the EF6 demo day in September 2016.
Business model
LoopPerfect positions itself as a dev-tools vendor for C/C++ engineering teams, distributing Buckaroo and associated libraries as open-source projects on GitHub under permissive licenses (mostly MIT, with one AGPL-3.0 repository). The sources do not describe pricing, a commercial product tier, or how the company monetizes.
Traction
Traction visible in the sources is limited to open-source engagement metrics on GitHub: Buckaroo has about 946 stars and 30 forks, rxterm 267 stars, neither 258 stars, conduit 149 stars and valuable 132 stars. Buckaroo shows 59 open issues (14 flagged as needing help) and the buckaroo-wishlist repo lists 81 open requests. The most recently updated repository shown is Buckaroo, last updated December 2022; several other repositories were last updated between 2019 and 2021, and the documentation repo is archived.
Latest developments
The most recent activity evidenced in the sources is the December 2022 update to the Buckaroo repository on GitHub. The company website continues to describe LoopPerfect as a dev-tools company building Buckaroo, and it remains listed in the Entrepreneur First portfolio.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
LoopPerfect operates in the developer tools and infrastructure segment, specifically C/C++ build and dependency management, and is an Entrepreneur First portfolio company. The sources provide no market-share, ranking, or competitor comparison data.
Technology
Buckaroo is a decentralized package manager for C/C++ that resolves and installs modules cross-platform, built on top of the Buck build system to produce fast, reproducible builds. The Buckaroo client itself is implemented in F#, while the company's supporting open-source libraries are written primarily in C++ (including monadic error-handling types, a value-semantics smart pointer, and coroutine-TS-based stream primitives). Additional tooling includes a Visual Studio-to-Bazel project converter and Skylark (Starlark) packaging utilities.
Go-to-market
Distribution is developer-led and open-source oriented: Buckaroo and related libraries are published on the LoopPerfect GitHub organization, with installation supported via a dedicated Homebrew tap and a public wishlist repository through which users request additional packages.
C and C++ software engineers and development teams that need to consume third-party modules and maintain consistent, reproducible cross-platform build environments.
Geography
Associated with London and the Entrepreneur First programme in London, where the company pitched at EF's sixth demo day in September 2016. No other locations are indicated in the sources.
History
The company pitched at Entrepreneur First's sixth cohort demo day, held at Facebook's UK headquarters in London on 6 September 2016, alongside 20 other startups; at that time its stated mission was to streamline C++ development via a just-in-time compiler allowing program logic to be updated without restarting a running application. Its later and current public positioning centres on Buckaroo, the C/C++ package manager. Public repository activity spans roughly 2018-2022 based on last-updated dates, with the Buckaroo documentation repository archived and Buckaroo itself last updated in December 2022.
Risks & controversies
Publicly visible development appears to have slowed: the flagship Buckaroo repository was last updated in December 2022 and most other LoopPerfect repositories were last updated between 2019 and 2021, with the documentation repository archived. The GitHub organization has no public members listed. No funding, revenue or customer data is available in the sources, and no controversies are reported. Note that several similarly named entities exist (Loopt, Loop Commerce, and an unrelated audio-loop tool at loopperfect.app) and should not be conflated with this company.
