Welcome to Horizon Labs. I can help you scope a build, compare package options, talk through existing codebases, or point you to the right next step when you're ready to talk to a human at /contact.
Your Get-Things-Done Engineers
Horizon Labs is a product development agency for teams that need to move fast without breaking things. Founded in 2019 out of YC, we partner with engineering leaders, SMB owners, marketplace operators, and startup founders to ship products their customers love.
Use our AI agent to explore our case studies, tech stack, capabilities, pricing, and resources. Every engagement is backed by clear estimations, 6-month code warranty, US hours (6am-6pm Pacific), with contracts and IP protections under US law.
Building something new?
Fixed-price packages. No hourly billing disputes. Clear scope, clear timeline. 6-month warranty. Prices are ~50% below our standard hourly equivalent — made possible by senior engineers using AI to cut time without cutting quality.
Our fixed-price guarantee applies to net-new code we write from scratch. Already have a codebase? We'll review it free and tell you honestly whether we can work with it under the same terms, or if a different approach makes more sense. Otherwise we prefer being able to control the codebase from start to finish.
Dev-Ready Product Wireframes
Fixed price · 14-day turnaround
We turn your idea into a working Figma file and clickable prototype app that founders can test with users, investors, and their own team before development starts. We document screens, workflows, user flows, interaction logic, and edge cases so engineers can follow the blueprint instead of guessing. Credited in full toward MVP Launch if you continue — your remaining MVP scope is reduced by $2,500. Payment: $1,250 at signing, $1,250 after delivery and approval.
Custom MVP Built with AI
Fixed price · Launch within 60-90 days
A production-ready web app built from scratch by senior engineers, with AI woven in where it moves the needle, not bolted on for show. Documented, security-reviewed, and SEO-ready at launch. 6-month warranty on all delivered code. Payment: 6 × $2,500-$5,000 — first sprint 2 weeks after signing, last after delivery and approval.
Launch + Go-to-Market
Fixed price · Launch with advanced SEO in 60-90 days
Everything in the Custom MVP, plus the GTM engine that lands your first users: ICP definition, advanced SEO, weekly human-written posts paired with AI content, automated social publishing, and behavior-targeted analytics. Payment: 6 milestone-based installments matched to final scope — first sprint 2 weeks after signing, last after delivery and approval.
Already have a product or need something more demanding?
Senior specialists on demand. Hourly, scoped by sprint, with a 6-12 month warranty on all delivered code.
Front-end / Back-end / Full-Stack
Startup and small-business rate
Senior full-stack engineers on demand for net-new builds, experiments your team is too busy to run, or backlog you need cleared. 10+ years average experience, overlapping US hours, direct Slack access. You own every line in your GitHub org. Code only touches AI in secure environments.
Custom AI Engineering
MAANG + YC Engineers
Senior AI specialists for teams shipping real systems — voice and real-time speech, multi-agent orchestration, and local or on-prem LLMs on open-source stacks (Llama, Whisper, vLLM, LangGraph, LiveKit). We own the eval loop and leave you with a system your team can run without us.
Go-to-Market Engineering
Flat monthly retainer · 3-month engagement
For launched products that need a real growth engine. We audit what you already have, fix the gaps, or build the system from scratch: ICP clarity, technical SEO, content strategy, human-written posts paired with AI workflows, analytics, and automated distribution. Goal: kickstart organic traffic or help existing traction grow 2x-4x within 3 months, with systems that keep running after the engagement ends.
