Software studio

We build software ambitious teams bet on.

Sagenly is a senior software studio. We design, ship, and scale web platforms, AI products, and design systems — from first commit to global launch. No agencies-in-between, no junior hand-offs.

01What we do

Six disciplines. One shipping team.

We cover the full product lifecycle — strategy, design, engineering, and operations — so you never stitch vendors together. Senior people, end to end.

Production-grade apps

Web Platforms

High-performance Next.js platforms, dashboards, and marketplaces engineered for scale — sub-second loads, edge-rendered, fully typed.

  • Next.js + React
  • Edge / Serverless
  • Design systems
LLM & RAG systems

AI Products

Custom copilots, retrieval pipelines, and agents wired into your data — shipped responsibly with evals and guardrails.

  • LLM apps
  • RAG pipelines
  • Evals & guardrails
Reusable at scale

Design Systems

Token-driven component libraries your whole org can build with.

  • Tokens
  • Component libs
  • Docs
Ship daily, safely

Cloud & DevOps

CI/CD, IaC, observability, and zero-downtime deploys on AWS, GCP, or Vercel.

  • CI/CD
  • IaC
  • Observability
One codebase, every device

Mobile & Cross-platform

React Native and Expo apps that feel native, shipped to iOS and Android from a shared core.

  • React Native
  • Expo
  • Offline-first
Pipelines & warehouses

Data Engineering

Streaming pipelines, warehouses, and analytics layers that turn raw events into decisions.

  • ETL/ELT
  • Warehouses
  • Realtime

Not sure which fits? Tell us what you’re building and we’ll map it back.

02How we work

A process that shows its work.

No black boxes. You see progress every week, with senior people on the build from day one to launch — and beyond.

011–2 weeks

Discover

We embed with your team, map the problem space, and pressure-test assumptions before a line of code. Output: a shared blueprint everyone signs off on.

  • Discovery workshop
  • Technical spec
  • Risk register
022–3 weeks

Design

Information architecture, flows, and a clickable prototype in your brand. We design the system, not just the screens — tokens, components, and motion.

  • Prototype
  • Design tokens
  • Component sketches
036–12 weeks

Build

Senior engineers ship in two-week increments against the plan. You get a working build every Friday, with demos and a live status board.

  • Weekly releases
  • CI/CD pipeline
  • Live status board
041–2 weeks

Ship

Hardening, load testing, observability, and a staged rollout. We don't call it done until it's in your users' hands and the dashboards are green.

  • Load tests
  • Observability
  • Launch runbook
05Ongoing

Scale

We stay on as a fractional engineering team — performance work, new features, and on-call support so you can keep momentum after launch.

  • Retainer
  • On-call
  • Roadmap reviews
03Selected work

Products that earn their keep.

05The studio

Senior people, no hand-offs.

Sagenly is a deliberately small studio of senior engineers and designers. The person who scopes your project is the person who writes the code. No layers, no juniors learning on your dime.

06Voices

The people who bet on us.

Founders and engineering leaders who put their roadmap in our hands — and came back for the next one.

Sagenly replaced a 12-person agency and shipped faster. They wrote the spec, the design system, and the platform — and they were the ones on the call every Friday. It's the most senior team I've worked with.

01

We'd been burned by AI prototypes that hallucinated in production. Sagenly built the eval harness first, then the product. Accuracy went from 61% to 94% in a quarter. They think like scientists.

CTO · Mosaic AI
02

Our patients can't tell the app was built by a small team, and that's the point. Offline-first, accessible, and on-brand. Lumen launched on time and we haven't had a P1 in eight months.

They treated our robotics fleet like a product, not a contract. The control plane is observable, tested, and documented well enough that our in-house team picked it up without a hitch.
