We help startups and teams launch AI products, automate data work, and ship production-grade software — fast, senior-built, and fixed-scope. You own the code; we own the outcome.
# From idea → production def ship(idea): mvp = build(idea, stack="FastAPI + LLMs") mvp.test().scale() return deploy(mvp, to="cloud") # shipped ✅ result = ship("your_vision")
No vague hourly billing. Pick the outcome you need — we scope it, price it, and ship it. You own 100% of the code and IP.

A look at how we turn messy, manual problems into reliable systems that run themselves.
A client needed structured infrastructure-project data across 27 countries — impossible to gather and keep current by hand.
Built a large-scale pipeline on SerpApi (Google Search + AI Overview) with automated CAPTCHA handling, structured parsing, and OpenAI batch processing into a queryable database.
2,046 queries across 27 countries turned into one clean, queryable dataset — replacing weeks of manual research with a repeatable engine.
Foreclosure lead generation meant manually checking dozens of US county court & sheriff sites every single day.
A daily Playwright (stealth) pipeline with proxy rotation that harvests filings, dedupes them, enriches via skip-trace APIs, and auto-pushes qualified leads into GoHighLevel CRM — with daily summaries and failure alerts.
A fully unattended lead engine — enriched, qualified leads land in the CRM every day with zero manual work.
Engineering teams had no single, live view of pushes, PRs, deploys, and incidents as they happened.
An event-driven platform on FastAPI + Kafka streaming events into PostgreSQL & OpenSearch with Valkey caching, pushing updates to dashboards over Server-Sent Events.
Sub-second live observability — teams see every deploy and incident the moment it happens, not minutes later.
Clinicians lose hours to manual note-taking and documentation after every consultation.
A voice-first Django platform integrating AssemblyAI speech-to-text with Claude, Groq, and Gemini for clinical entity extraction, multi-turn chat, and auto-generated summaries.
Consultation notes generated automatically from voice — turning hours of admin into seconds.
Founders who need to launch an AI product fast, validate it with real users, and iterate — without burning the round on a slow agency.
Product teams bolting on copilots, RAG search, or automation — who want it done right, integrated cleanly, and shipped to production.
Businesses drowning in manual data work who need reliable scraping, enrichment, and automation pipelines that just run.
We're honest about fit: if you want the cheapest possible developer or a quick throwaway demo, we're probably not your team. If you want it built to last and shipped on time, we are.
How we de-risk your project from day one.
You work directly with the engineer building your product — no juniors learning on your budget, no account-manager wall.
100% of the source code and IP is yours on delivery — clean repos, documentation, and a deployment runbook included.
Agree the scope and the number up front. No surprise invoices, no scope creep on your dime.
Evals, monitoring, guardrails, and tests — built for real users from day one, not just a demo that looks good.
Real production systems behind us — LLM platforms, data pipelines across 27 countries, and real-time event systems.
Free strategy call with a clear scope and quote — and if we're not the right fit, we'll tell you straight.
We scope the problem, define success, and map the simplest architecture that gets you there.
Tight iterations with working software each week — typed, tested, and reviewed.
Containerized deploys with CI/CD, monitoring, and a runbook so it stays up.
Performance, observability, and iteration as your usage and team grow.
Kortex Labs is led by Saif Ur Rehman, a senior Python engineer with 5+ years building AI-powered products, multi-tenant SaaS, and production-grade APIs. The work spans LLM APIs, RAG, vector databases, event-driven streaming, and deep roots in web scraping and ETL.
Remote-first and product-minded — you get direct access to the person doing the engineering, not a layer of account managers. We translate complex systems into clear, shippable software.
Everything you need to know before starting a project with us.
We build AI & LLM products (RAG, agents, semantic search), backends and APIs on FastAPI/Django/NestJS, multi-tenant SaaS platforms, web scraping & data pipelines, modern React/Next.js frontends, and cloud/DevOps — end to end, from MVP to scale.
Yes. We're remote-first and work with founders and teams worldwide, with overlap across US, EU, and APAC time zones. Communication is clear, async-friendly, and direct with the engineers building your product.
It depends on scope. We offer fixed-scope project quotes and flexible monthly engagements. Send us your project details through the form below and you'll get a free quote within 24 hours.
We're currently available for new projects and can usually kick off discovery within a few days of your first message.
OpenAI, Claude, Gemini and open-source LLMs with LangChain and RAG; FastAPI, Django and NestJS backends; React, Next.js and TypeScript frontends; PostgreSQL, Redis and Kafka; deployed on AWS, GCP and Fly.io.
You do. On delivery, all source code and intellectual property are 100% yours, with clean repositories, documentation, and a deployment runbook.
