Python Development for US Startups & SMBs
We build Django and FastAPI applications, data pipelines, and AI backends that ship. AI-assisted engineering gets working software in your hands in weeks, not months, with senior engineers you talk to directly and full ownership of all code and IP.
What We Build in Python
End-to-end Python development (from a first MVP to modernizing a legacy Django product) across the frameworks and data tooling US teams ship on.

Django or FastAPI? How to Choose
The two frameworks solve different problems, and many products use both. Here's the honest version, so you pick the right tool instead of the trendy one. We help you make the call in discovery, before any budget is committed.
Choose Django when…
- You want a full-featured web app with admin, auth, and ORM out of the box
- You're building a SaaS, portal, marketplace, or content-driven product
- You value a batteries-included framework and a large, stable ecosystem
- Team velocity and convention-over-configuration matter more than raw async throughput
Choose FastAPI when…
- You need a high-performance, type-safe API or microservice
- You’re serving AI/LLM features, RAG endpoints, or heavy async I/O
- OpenAPI-first contracts and Pydantic validation are priorities
- You want a lightweight service rather than a full web framework
How We Start: Fixed Scope, Fast
We don't lead with open-ended retainers or an hourly meter. Every engagement starts with a focused, fixed-scope sprint, so you get a clear deliverable and a real estimate before any long-term commitment.
Discovery Sprint
- Scope, architecture & stack recommendation
- Django vs. FastAPI decision
- Timeline & fixed estimate
MVP / Product Build
- Launchable Python app or API
- Core flow, data model & integrations
- Deployed, instrumented & documented
Modernization & Audit
- Full codebase & security audit
- Performance & dependency fixes
- Stabilized build + modernization roadmap
Every engagement starts with a fixed-scope sprint and a clear deliverable. You get a concrete estimate before any long-term commitment.
Why US Teams Choose MicroPyramid
You're not hiring a 500-person body shop with a rotating bench. You get a focused, senior Python team that ships.
AI-Assisted, Weeks Not Months
We build with AI across coding, testing, and review, so working software lands in weeks, not the months a traditional agency quotes.
Senior Engineers, Direct
You work with the people writing the code, not account managers or a rotating bench of juniors handed your project.
You Own Code & IP
Full source code, IP, and infrastructure are yours from day one. We sign NDAs and IP-assignment before work begins.
US Time-Zone Overlap
Daily overlap with ET/PT for standups, demos, and reviews. Async-friendly, but reachable when you need a real conversation.
How We Build Your Software
A proven four-stage process with weekly demos and senior review, so you always know exactly where your project stands.
Discovery & Scope
Requirements, data model, framework decision, and a fixed estimate before a line of code is written.
Architecture & Design
API contracts, data architecture, and the infrastructure your app will run on, agreed up front.
AI-Assisted Build
Sprint-based development with weekly demos, CI/CD, automated tests, and senior review on every change.
Deploy & Support
Production deployment on AWS or GCP, monitoring, and ongoing iteration after launch.
The Python Stack We Build On
Current, well-supported tools across web frameworks, data, AI services, and the cloud your app runs on.

Python Development FAQs
Straight answers to what US founders and CTOs ask us before starting a Python project.
What drives the cost of Python development?
The main drivers are scope and feature count, the complexity of your data model, the number of third-party integrations, and any compliance or security requirements. A focused MVP or API costs far less than a moderately complex SaaS app, which in turn costs less than a large multi-team or enterprise platform. We give a fixed estimate after a short discovery sprint rather than an open-ended hourly meter.
How do you keep costs efficient?
We run senior-only teams with no junior bench, so you are not paying people to learn on your project. We use AI-assisted engineering across coding, testing, and review, which reaches the same outcome in fewer hours, and we work in fixed-scope sprints with a clear deliverable. You own all code and IP from day one.
How long does it take to build a Python application?
We ship a launchable MVP or API in roughly 4-8 weeks and larger platforms in a few months, faster than the 6-12 months traditional agencies quote, because we use AI-assisted engineering across coding, testing, and review with senior oversight on every change.
Should I use Django or FastAPI?
Choose Django for full-featured web apps and SaaS. It gives you admin, auth, and an ORM out of the box with a large, stable ecosystem. Choose FastAPI for high-performance, type-safe APIs, microservices, and AI/LLM or RAG service layers where async I/O and OpenAPI-first contracts matter. Many products use both: Django for the app, FastAPI for the AI and high-throughput services. We help you decide in discovery, before any cost is committed.
Why choose Python for my project?
Python gives you fast development, a huge ecosystem, and the strongest path to AI and data features of any mainstream language. Django and FastAPI cover everything from full web apps to high-performance APIs, and the same stack scales from MVP to enterprise, so you avoid a costly rewrite as you grow.
Can you build AI features into a Python backend?
Yes. Python is the default language for AI, and we build LLM features, RAG pipelines, and AI agents directly into FastAPI or Django backends, adding AI chat, search, and automation to your product rather than bolting on a separate system.
Can you rescue or modernize an existing Django or Python codebase?
Yes. We audit the codebase, security, and dependencies, fix performance issues, upgrade Django and Python versions, and modernize the architecture incrementally, without a risky full rewrite. Many engagements start as a modernization and audit sprint.
Do you work with US companies and what about time zones?
Yes, most of our clients are US-based startups and SMBs. We keep several hours of daily overlap with US time zones (ET/PT) for standups, demos, and reviews, and you work directly with the senior engineers building your software.
Have a Django product that needs modernization or rescue?
We offer focused Django Modernization Sprints: codebase audits, architecture cleanup, and performance or security improvements for existing Django products.
