Symptom 01
The frontend is in your way
Ten-minute builds. A codebase your team's a little scared of. Most weeks go to keeping it alive instead of shipping the thing on the roadmap.
Senior engineering
for product teams
who can't afford
to get it wrong.
Old frontend. Mobile app that never shipped. AI feature stuck at the demo. That's the work we take. Small senior team, fixed prices, no PM in the middle.
02The problem
Most agencies can't ship what product teams actually need.
An old React app, a half-built mobile version, an AI feature that fell over the first time a real user touched it. None of this gets fixed by a shop with 40 engineers rotating on and off the project. It gets fixed by people who've shipped this kind of thing before and stay until it works.
Symptom 02
Mobile keeps slipping
Features land on web months before mobile. Sometimes never. It feels like two different products under one logo, and customers notice.
Symptom 03
The AI feature breaks in prod
The demo went great. Then a real user typed something weird and it fell over. No evals, no guardrails, no idea what the model is doing.
03What we build
Four kinds of work. Same way of doing them.
Each one is fixed scope, fixed price, and run by a senior engineer from day one. Pick the shape that matches what you're trying to ship.
Engagement 01 · Web
Frontend & Backend Modernization
Rebuild the old React or Angular app and the services behind it. Design system first so the team can keep shipping while we go. Usually 90–120 days to a clean release.

Engagement 02 · Mobile
Cross-Platform Mobile
One codebase, iOS and Android in sync. Works offline. Logs the things compliance asks about. A good fit if your app handles money, health, or regulated data.

Engagement 03 · Data
Modern Data Pipelines
Streaming and batch on a stack that won't surprise you at the next bill. Kafka, Flink, Snowflake, dbt. Lineage and audit trails come standard, not as an upsell.

Engagement 04 · AI
Production-grade AI Agents
Ship AI agents into a product that already has customers, without them leaking data or making things up. Evals, guardrails, run traces, and the dashboards you'll want the first time something goes weird.

04Where we go deep
Focused on purpose. Honest about the rest.
These are the kinds of teams we work well with. The playbook is mostly the same across them, and we'll say so when we're outside it.

Focus · SaaS
SaaS scale-ups
B2B SaaS, Series A through C. Usually a frontend that's getting in the way, or a mobile app that's been on the roadmap for two years and never quite shipped.
Focus · AI
AI-enabled products
Teams putting LLMs, agents, or RAG into a product that already has paying customers. Evals are mandatory before we ship. The demo can't be the test suite.
Focus · Data
Data-heavy B2B tools
Products where the data UI is the product. Real-time charts, big grids, query builders that have to stay snappy when there are millions of rows underneath.
Focus · MVPs
Funded-stage MVPs
Seed and Series A teams who want a real v1 in weeks, not months. Built well enough that you're not throwing it away when you raise the next round.
05Why Hotreloads
Three things we do differently.
Not slogans. They're the actual reason we turn down a fair amount of work and the reason the work we take usually ships.
Principle 01
The people who quote are the people who code
Whoever shows up on the first call is the one writing the commits. No bait-and-switch staffing, no junior-led team, no project manager between you and the engineer doing the work.
Principle 02
Priced on outcomes, not hours
Fixed scope, fixed price, tied to something we can both measure: time to first release, latency cut, dollars saved. You know the number on day one. So do we.
Principle 03
We'll tell you if we're not the right fit
FinTech is where we go deepest. There's a handful of areas we know well next to it. Outside that, we'll say so, and we usually know someone who'd be a better fit.
06Proof
Working code speaks louder than decks.
Three things you can read or actually run before we ever get on a call. Same standard of work we'd ship to a paying client.
Proof 01
Anonymized case study
A payments console audit-trail refit that took client-side coverage from 62% to 100% across six regulated surfaces, in fourteen weeks, without disturbing the live system. The first regulator query landed three months later and was answered in four hours.
Proof 02
Open-source UI kit
The React starter we reach for on day one of a build. Accessibility, i18n, audit logging, the patterns we use in regulated work. MIT, no strings.
Proof 03
Where we go deep
FinTech is our anchor, with SaaS scale-ups, AI-enabled products, data-heavy B2B, and funded MVPs as the adjacencies. We tell you which side of that line we're on, every time.

We hop on a call, look at the stack and what you're trying to ship, and write up what we'd actually do. No slides.

If it makes sense to keep going, we write the scope, the price, and the timeline. You see exactly what gets built and when.

A small senior team works in your repo. Demos every Friday, shared Slack, you see every commit as it lands.

Your call
Hand off or stay on
We hand it off cleanly, or stick around to run it. Either way the code is yours and your team can extend it the next day.
08About
Why Hotreloads exists.
We started Hotreloads after watching too many good roadmaps stall behind vendors who didn't understand the product, the codebase, or what "urgent" meant in the week before a board update. We'd seen it from both sides: as engineers inside companies trying to ship, and as the people called in afterwards to fix what someone else built.
So we built the kind of team we wished we could hire: small, senior, and direct about what we know how to do well, and what we don't.
