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.
You’ll own the data and workflow systems that power Lapel: how we sync, parse, store, transform, permission, and retrieve information from the external systems our customers rely on to serve their customers.
The best version of Lapel feels simple on the surface because the platform underneath is thoughtful, durable, and extensible. Your job is to build that platform and enable a growing set of products built by our engineering team and by our customers themselves.
Contribute to our integration framework for how external systems authenticate, sync data, transform records, subscribe to events, and expose actions
Building permissioning infrastructure that keeps customer data isolated, secure, and correctly scoped across integrations, APIs, agents, and product surfaces
Designing event and subscription systems that let internal services, external integrations, and workflows react to changes across the platform
Building workflow infrastructure for long-running jobs, retries, orchestration, backfills, customer-specific automations, and agent-driven actions
Building the platform APIs, services, and abstractions that let product engineers move faster without re-solving data, permissions, or workflow problems each time.
Lapel is built end-to-end in TypeScript in a single monorepo.
React, Vite, and Tailwind on the frontend;
Node.js and Postgres on the backend;
Temporal and Pulsar to power orchestration.

A trillion-dollar problem hiding in plain sight. Companies spend over $1T a year on customer-facing teams and $150B on the tools meant to support them, yet every team still pieces context together across a dozen disconnected systems. We're rebuilding this from the foundation, and AI makes now the only moment it's possible.
The most interesting place to apply AI is where the work actually happens. Customer operations is one of the largest, most under-built surfaces in software. Every company runs on it, every team feels the pain, and the tools haven't been seriously reimagined in fifteen years. We think the next generation of category-defining B2B companies will be built here.
One platform, every customer-facing team. Sales, success, support, and ops all serve the same customer relationship, but each one buys a different tool to do it. Owning the foundation means the surface area grows with the company, from a single team to the entire revenue org to the whole business. That's the market, and the mission: better service at internet scale.
