At Lapel, we believe the most hospitable companies win. We're building the data, infrastructure, and tools that help customer-facing teams understand every customer and act on that insight at scale throughout the entire customer lifecycle.

Most internet businesses want to treat customers well, but their tools work against them. We’re building the layer that makes every interaction feel personal again: unifying context, coordinating action, and closing the gap between intent and experience.

It’s a technically ambitious challenge spanning data infrastructure, AI, and systems design – with a deeply human outcome: helping software companies serve people better. We call it hospitality at scale.

We’re well-funded, backed by top-tier investors, and already working with exceptional companies, from fast-growing startups to large enterprises. We’ll share more details when we talk.

About This Role

At the core of Lapel are well thought-out and abstracted primitives. You'll own the object models, contracts, and abstractions that every product experience is built on top of: customer records and threads, workflows, permissions, and actions.

Great primitives make Lapel feel powerful, coherent, and obvious. Poor primitives lead to complexity everywhere else. You’ll be responsible for making the foundations simple enough to build on, flexible enough for enterprise customers, and opinionated so that Lapel never becomes a blank canvas.

What You’ll Do

Build the state, history, permissioning, and event models that make every Lapel primitive reliable and extensible

Design an extensibility model that gives customers power without turning Lapel into an unstructured blank canvas

Make primitives usable by both people and agents, with clean actions, histories, permissions, and memory surfaces

Help decide what should become a Lapel default, what should be configurable, and what should remain fully custom
