Custom Software Development for businesses in Greater Los Angeles
Los Angeles is the most expensive place in the country to hire an agency and one of the easiest places to get a vague quote. The large shops start engagements in the high five figures and staff them with a bench you never meet; the offshore alternative is cheap until you realize you've become the project manager. We sit in the gap: a senior, founder-led team that scopes honestly, prices fixed, and ships real products — more than twenty of them across entertainment, e-commerce, hospitality, insurance, fintech, and consumer apps.
The work looks like this: a self-serve sponsorship platform with an interactive vehicle configurator and a live tracking demo that follows a car across LA (Kestrel Fleet), a headless storefront and custom admin app for a growing Shopify brand (Blushing Bee), a nightlife operations platform for high-end venues (On Stage), and a full operations system that replaced a Monday.com + n8n stack for a sales organization (Refuge Memorial). Custom web apps, internal tools, CRMs, and the AI features that now belong inside all of them.
Every engagement starts with a short paid discovery, ends with a fixed-fee estimate you own regardless of who builds it, and ships in two-week sprints to a GitHub org in your name. We meet clients in person across LA County — Silicon Beach, Downtown, Pasadena, the Valley — and work remote-first with everyone else in California.

The software your Los Angeles business is missing
From a first customer-facing product to a full operations platform, we build the systems that let an LA company scale without hiring a department to manage the tools.
Custom Web Applications
Customer portals, self-serve sales tools, dashboards, and SaaS products — React and TypeScript with a real backend.
Internal Tools & Operations Software
The systems your team runs the business from: approvals, scheduling, reporting, content pipelines, job tracking.
CRM & Sales Systems
Pipelines built around how you actually sell — sponsorships, memberships, wholesale, bookings — with forms, email, and calendar wired in.
Mobile Apps
iOS and Android apps in React Native or native Swift — consumer products, companion apps, and field tools.
AI Agents & Automation
LLM-powered workflows that draft, classify, transcribe, summarize, and route — grounded in your own data.
Media & Content Systems
Video processing, transcription, captioning, asset management, and publishing pipelines for studios, streamers, and creators.
Integrations & APIs
Stripe, Shopify, QuickBooks, Google Workspace, Twilio, HubSpot, and the platforms you already run — connected properly.
Fractional CTO
Architecture, code review, vendor decisions, and hiring help for LA founders raising or scaling without a technical co-founder.
Built for the way Los Angeles businesses operate
Studios, creators, DTC brands, venture-backed startups, and hospitality groups — different industries, the same gap between what they need and what they can buy off the shelf.
Startups and venture-backed product companies
Pain
You have a term sheet or paying design partners, a deadline, and quotes from LA agencies that would eat half the round before you've shipped anything.
Solution
A fixed-fee MVP with a senior team, a transparent scope, and a codebase you own when it's time to hire your first in-house engineers.
Studios, streamers, and creator businesses
Pain
Content pipelines, rights tracking, talent coordination, and publishing live in spreadsheets and a dozen SaaS tabs that don't talk to each other.
Solution
Purpose-built internal tools and AI-assisted media pipelines — transcription, highlight detection, captioning, asset workflows — that fit how your team actually produces.
DTC and e-commerce brands
Pain
The Shopify theme is slow, marketing wants things it can't do, and operations manages orders, inventory, and wholesale across four systems.
Solution
A headless storefront for speed and control, plus a custom admin app that puts orders, products, customers, and wholesale in one place.
Hospitality, nightlife, and events
Pain
Reservations, ticketing, staffing, promoter tracking, and performer check-ins are scattered across tools that were never built for a venue group.
Solution
Operations platforms built for multi-venue hospitality — we've shipped ticketing, venue check-in, and event sites for exactly this.
Built for ownership, scalability, and the long haul
A software partner priced for LA founders, not LA agencies.
Local and accountable
A team you can meet in person in Los Angeles. No offshore hand-offs, no account managers between you and the engineers.
You own everything
Full IP assignment, your GitHub org from day one, and infrastructure in your accounts — never locked in to us.
Senior engineers only
The people who scope the project are the people who build it. 20+ shipped products, 5+ years, no junior bench.
Opinionated, but not married to a stack
We default to a tight set of tools we trust in production, and pick the right one for each layer.

Questions about software development in Los Angeles
What Greater Los Angeles businesses usually ask before kicking off a project with us.
Still unsure what you need?
Book a 30-minute technical discovery call. We'll help you clarify scope and the right next step.
Are you located in Los Angeles?
KeyesCode is headquartered in Tampa, Florida, and serves Los Angeles as one of our two focus markets. We work on-site with LA clients — kickoffs, working sessions, and reviews across Los Angeles County — and run day-to-day collaboration remote-first over Slack and video, the same way most LA teams already work with their own engineers.
How much does custom software development cost in Los Angeles?
Scope drives it, which is why we don't quote off a phone call. A short paid discovery (usually 1–2 weeks) produces a fixed-fee estimate you own whether or not we build it. Focused internal tools and MVPs typically start in the low five figures; full operations platforms and multi-platform products are larger. That is well under what most Los Angeles agencies open with, and we'll tell you early if an off-the-shelf tool would do the job for less.
How long does a typical project take?
Most focused builds ship a usable first version in 6–12 weeks. Larger platforms are staged so something is live and generating value within the first couple of months, then extended in two-week sprints. Average kickoff after signing is about two weeks.
Who owns the code and the accounts?
You do. We assign all IP on delivery, push to a GitHub organization in your name from day one, and deploy into cloud accounts you control. If you raise a round and hire in-house, or switch vendors, nothing is held hostage.
Do you work with entertainment and media companies?
Yes. We've built AI-powered video pipelines — highlight detection, transcription, captioning, vertical clip export — as well as operations software for hospitality venues and self-serve sales platforms. For studios and creators the work is usually internal tooling and content automation rather than a public product, and we're comfortable with NDAs, unreleased content, and strict data handling.
Can you take over software another Los Angeles agency built?
Often. We start with a paid code and infrastructure audit, tell you honestly whether it's worth stabilizing or replacing, and if we take it on we modernize incrementally so your business keeps running the whole time.
