Case Studies
Daylight.xyz was a Web3 discovery platform backed by Union Square Ventures and 1kx. Our team joined after their seed round and was responsible for their backend data platform, recommendation system and REST APIs. We stayed on after the initial launch, scaling the platform to power the "Explore" screens of the largest names in crypto including Rainbow and Zerion.
To deliver real-time crypto recommendations, our team built data pipelines providing low-latency streams of NFT mints and on-chain function execution using raw transaction data from Ethereum, EVM L2s, and Solana. This data was rolled up into first-party user profiles using data from Farcaster and other address verification networks, and then analyzed to identify each person’s habits and activity on-chain.
The system identified trending mints on-the-fly and used a multi-faceted model to provide each user with personalized suggestions based on their past mints, social follows, dapp interactions, and more. A key challenge was doing this on a short TTL: crypto trends moved fast, and users received push notifications within minutes of recommended actions going live on chain.
Our team used extensive Postgres partitioning and sharding to scale Daylight, and Grafana, Prometheus, and PgAnalyze for careful index tuning and performance management as large wallet partners came onboard. In 2025, the API was serving more than 4,000 recommendations / second to partners and we helped Daylight recruit and onboard two more engineers. In 2026, Daylight was acquired by Consensys, the team behind MetaMask.
Snappt is a Los Angeles–based proptech company providing fraud and income verification software for multifamily property managers, backed by $152M in funding. In 2024, Snappt approached Foundry 376 with a challenge: the core of their system was an aging, monolithic Elixir application, and they needed to expose internal capabilities as formalized, partner-facing APIs to support a growing enterprise business.
Our team built a new Node.js backend designed to be a drop-in replacement for the Elixir API surface. It connected to the same databases and data providers and was extensively verified to serve identical responses. This allowed internal systems to adopt it immediately without disrupting workflows. With this foundation deployed, we added formal enterprise APIs and high-quality OpenAPI documentation.
Over two years, our team made performance optimizations across their systems to support large enterprise customers, replaced aging PDF reports, added robust webhook delivery infrastructure, and more. The compatibility-first approach was critical to the project’s success—we were able to deploy our solution quickly, swap it into place, onboard enterprise partners onto a modern API surface and reduce the scope of the Elixir codebase.
Team
Ben started his career building award-winning apps for iOS, led front-end engineering at Nylas in San Francisco and started Foundry 376 to scale his passion for 0-1 product engineering. He's an avid builder and a hobbyist furniture maker.
Joe spent six years as a mobile developer, launched and sold a computer-vision parking startup, then joined Foundry to build web applications. He's picked up deep expertise in Node, Postgres, and scaling demanding web applications.
Sean joined Foundry in 2022 and works across front-end and backend features. When he's not writing code, he's traveling the southeast for his band, Kid Pastel.
Manila brings a user-centric focus and eye for detail honed during her career in architecture. When she isn't at a big screen, she can be found at a smaller one.
Adam built Android apps early in his career, then co-founded a computer vision startup. He led development of registration systems at Paralon before joining Foundry.
Trent builds component libraries, design systems, and polished React interfaces. When he's not at his desk, he's traveling.
An experienced CTO and full-stack engineer, Russ is also a co-organizer of NashJS, Nashville's JavaScript community.
Open Source
A free, native desktop email client for Mac, Windows, and Linux trusted by over 800,000 users. Built with Electron and C++, Mailspring features advanced search, unified inbox, snoozing, and send later with an optional Pro tier.
Codako is a game programming tool designed for young learners ages 6-12. Built with contributors from MIT CSAIL and Dave Smith — a pioneer of programming-by-demonstration at Apple's Advanced Research Group in the 1990s — it’s a re-imagination of KidSIM, Cocoa, and Stagecast Creator, tools that Ben first programmed with.
