10 Best Python Development Companies in 2026

Is Python Just an AI Language Now?

Python is the home of machine learning and artificial intelligence, with the entire tooling layer—TensorFlow, PyTorch, scikit-learn—built on Python first.

However, Python is also a mature web app & data backbone, with Django and FastAPI having powered household names for years. Think of Instagram and Spotify, both scaled on Django well before the generative AI era.

The strong dual identity makes hiring a Python development company a strategic advantage for a startup. 

The same ecosystem provides data science and clean API development, along with a production-grade backend. As a result, your MVP can grow into an AI-driven product easily when you need it.

At Lemon.io, we know Python, the teams who choose it, and what founders need. For this list, we focused on Python-only or Python-first shops to let you discover top players of different sizes, specializations, price tags, and time zones, and choose those that work for you. 

Want more control over your project rather than outsourcing the development entirely? Hire dedicated Python developers on our engineers marketplace and start building next Monday. 

Quick Top 10 Python Firms Comparison

Python might not be your only contender—if you’re comparing ecosystems, we’ve done the same deep dive for the top Ruby on Rails dev companies and Java development firms for startups.

#1. Torchbox

Best for: content-heavy platforms of impactful non-profits needing a proven CMS

Industries: non-profit, higher education, government

Achievements: creators of Wagtail; NASA, Google, the NHS, Oxfam, the Red Cross, US and UK government sites

Source: Torchbox website

Founded in 2000 in the UK, Torchbox’s claim to fame is enormous: it created Wagtail, the leading open-source Django CMS, used by NASA, Google, the NHS, Mozilla, and the US and UK governments—arguably the single largest contribution to the Python ecosystem by any agency, with profits reinvested into the project.

Beyond content platforms, Torchbox’s engineers build custom web apps with data visualization, third-party API integrations, and PostgreSQL persistence layers. Caveat: it’s a broad digital agency (Drupal, SEO, video too), so Python-strong rather than Python-pure. One more nuance, the firm is focused on impactful projects and non-profits.

#2. STX Next

Best for: ML-heavy MVPs and digital transformation that needs one partner from strategy through delivery; good for well-funded scaling projects

Industries: FinTech, HealthTech, retail, IoT development

Achievements: Financial Times 1000, Deloitte Fast 50, repeat Clutch 1000 (top 1% globally)

Source: STX Next website

Founded in 2005 in Poland by Maciej Dziergwa, now on the advisory board following a private-equity investment. Twenty-one years on the market, 500+ people across eight Polish offices, the Netherlands, and a delivery center in Mexico. STX Next makes the top of this list on scale alone: it’s the rare Python software development company large enough to staff a full team while keeping deep bench strength. Its main asset is real machine learning muscle—it acquired ML firm Ermlab, whose CEO now heads its data engineering practice.

#3. Django Stars

Best for: founders who want a discovery-first partner and product ownership

Industries: FinTech, travel, healthcare, insurance

Notable clients: MoneyPark, PADI Travel, Molo Finance

Source: Django Stars website

Founded in 2008, now listed in Alicante, Spain, though Ukrainian-founded. Eighteen years in, Django Stars remains the purest play here: a monostack shop whose engineers have worked exclusively in Python since day one, which is why it anchors any serious conversation about outsourcing Python development.

The proof is unusually strong for its size—PADI Travel acquired the product the team built, kept them on, and named them a strategic partner. That’s the clearest signal on this page that a startup MVP can grow into something acquirable. The team of 100–150 leads with discovery and owns architecture decisions, according to Clutch reviews.

#4. Six Feet Up

Best for: architecture audit, big-data systems, and predictive analytics work on cloud infrastructure

Industries: enterprise, higher education, non-profit, government

Clients & achievements: Capital One, NASA, Purdue University, UNEP; AWS Community Hero (Calvin Hendryx-Parker), founder of IndyPy, hosted DjangoCon Europe

Source: Six Feet Up website

Founded in 1999 in San Francisco, relocated to Indiana in 2003, and at 27 years old, the oldest firm here. 

This woman-owned, certified consultancy specializes in high-end Python architecture and AI on AWS, and carries a 5-star Clutch referral rating. Its distinctive asset is community leadership: CTO Calvin Hendryx-Parker is an AWS Community Hero and founder of Indiana’s largest tech meetup, and the team built the platform that hosted DjangoCon Europe. 

Six Feet Up is consulting-forward—they sell strategic technology planning as its own service, which suits founders who need advice before code.

#5. REVSYS

Best for: architecture audit, performance reviews, and a second opinion before you commit to the budget

Industries: emerging technologies, education, high-traffic web platforms

Achievements: the team is now led by Jacob Kaplan-Moss (one of Django’s two original creators) and Frank Wiles (former DSF President); clients include Netflix and Sony 

Source: REVSYS website

Founded and led by Frank Wiles, former President of the Django Software Foundation and now a member of the Django Steering Council. US-based, distributed, around 10 people—the highest concentration of Django authority per capita anywhere. 

REVSYS is deliberately not a greenfield build shop; its distinctive value lies in deep IT consulting on performance, scaling, and code review, backed by testimonials from Django’s own co-creator. The smart play is to hire them for a few days to audit whoever else you choose, or to rescue a system straining under growth.

#6. Lincoln Loop

Best for: performance tuning and scaling of existing Django products that need to handle serious traffic

Industries: publishing, non-profit, education

Clients & achievements: Mozilla, Wharton, University of Delaware, NOLS

Source: Lincoln Loop website

Founded in 2007, US-based and fully distributed. Across 19 years, Lincoln Loop has claimed to be the first company focused solely on Django application development, and it remains a corporate member of the Django Software Foundation. 

Lincoln Loop’s distinctive asset is published expertise: the team wrote High Performance Django (a free online book) and built AppPack, a PaaS layer on AWS. The culture is unusual—remote-first, asynchronous, with open financials—and the work spans end-to-end delivery, including UI/UX design. Note that their rates sit at the premium end of the US market.

#7. Caktus Group

Best for: complex, mission-critical custom software development where reliability outranks speed

Industries: higher education, non-profit, government, HealthTech

Clients & achievements: Mozilla, UChicago, PBS; Libya’s SMS voter-registration system; Philadelphia’s COVID contact-tracing platform

Source: Caktus Group website

Founded in 2007 in North Carolina, and structured as a worker cooperative. Nineteen years in, Caktus earns its place through raw Django authority: co-founder Tobias McNulty helped build the messages framework shipped in Django itself, and the firm’s pitch is to optimize your architecture with you rather than build to spec. 

The distinctive achievement is a track record on high-stakes, data-intensive public systems—the kind of software engineering where correctness is critical. Expect thorough discovery and honest scoping over fast, cheap output.

#8. Sunscrapers

Best for: data-heavy products and teams that want strong senior-only expertise

Industries: FinTech, healthcare, logistics

Clients & achievements: Clutch #1 Python/Django firm under 50 people, maintainer of djoser, organizer of Warsaw’s Python meetup, DjangoCon, and Django Girls contributor

Source: Sunscrapers website

Founded in 2010 in Poland. At 40+ people, Sunscrapers stays deliberately small so clients reach senior engineers directly, with no account-management layer in the middle. Clutch has ranked Sunscrapers the #1 Python/Django firm worldwide with fewer than 50 people. 

The firm has strong open-source credibility: the team maintains djoser, a widely used Django authentication library with thousands of GitHub stars, and runs Warsaw’s monthly Python meetup. The stack spans Python, JavaScript, and AWS, with a serious data engineering practice built on tools like pandas, NumPy, or SciPy—Python-first rather than strictly Python-only.

#9. Fusionbox

Best for: US-based teams wanting senior-only delivery and a try-before-you-commit start

Industries: cutting-edge technology, professional services, education

Clients: Colorado Lottery, Emotional ABCs (used by 200,000 educators in 120 countries), Paterson Center

Source: Fusionbox website

Founded in 2002 in Colorado, an exclusively Python web development company and is strict about it. Fusionbox has been built with Django exclusively since 2013, keeps every engineer at a senior level, and never outsources: the team is 100% US-based. 

The distinctive feature is the lowest-risk entry model on this list—sprint-by-sprint engagement, so you can buy a single sprint to test the fit before committing further. They also sell standalone code review for security and design decisions, with real cybersecurity depth baked into their approach.

#10. PLANEKS

Best for: budget-conscious MVP and proof-of-concept builds that still need senior judgment

Industries: SaaS, eCommerce, eSports, fleet management, HealthTech

Clients & achievements: Spontivly, Upcomer, DigitalPlant, Santé.app; Clutch Global & Clutch Champion Winner; Top Python/Django firm on CodeUA and Techreviewer

Source: PLANEKS website

Ukrainian, startup-focused, and the most affordable credible option here. PLANEKS has delivered 150+ projects across SaaS, marketplaces, and data platforms—some serving 250,000+ users—and positions itself squarely as an MVP development partner for early-stage founders. 

PLANEKS’ strength lies in breadth within the Python web stack: the team works fluently with Django, Flask, and FastAPI, choosing the right tool for each build. Clients describe it as proactive, with the client showing up weekly with concrete proposals.

Lemon.io, the Resource-Effective Alternative

Vetting agencies take weeks—discovery calls, proposals, and rate negotiations. After that, you face another risk: vendor-owned domain knowledge, not yours. If you’d rather skip both issues, Lemon.io lets you hire Python developers directly: pre-vetted engineers matched to your stack, available within days. 

How does it differ from a traditional Python development company? 

You get the engineer, not the account-management layer, whether you need one senior backend developer or a small pod spanning API work, front-end development, and DevOps. Our human matchers can cover all your needs and advise on a winning combo of experts to get into your team.

The economics are worth understanding before you commit to any route. 

Lemon.io’s 2024–2026 benchmark, built on 2,500+ verified contracted engagements across 71+ countries, puts a senior Python developer (5–8 years) at $48.7/hr on average, and a strong senior (8+ years) at $58.7/hr—with European rates for a senior landing in the $18–54/hr band. 

Source: Software Developer Rate Benchmark Report (2024–2026) by Lemon.io

A Django specialist runs slightly lower—about $43/hr at a senior level—while an AI engineer commands $60.3/hr, and a strong senior reaches $79.2/hr, a reminder that machine learning and generative AI talent sits at the top of the market.

Source: Software Developer Rate Benchmark Report (2024–2026) by Lemon.io

Set those individual rates against the $100–300/hr an agency charges, and the gap is the agency’s margin, coordination, and delivery guarantee—sometimes worth it, sometimes not. 

Which route fits you? Three honest options, based on what you need:

• A Python development agency—best when you want someone else to own the delivery end-to-end: project management, QA, and accountability bundled in. Right for a complex build, or a non-technical founder who wants zero staffing burden.
• A fractional Python-focused CTO—best when your gap is judgment and architecture decisions. A few hours a week of dedicated senior oversight to challenge the spec, own architecture, and review whoever builds. Affordable leverage relative to its impact and the ideal complement to either of the other two.
• A tech talent marketplace (Lemon.io, Toptal, and similar)—best when you can direct the work yourself and want senior engineers without a premium markup or long contracts handled by you. The middle path: more control than an agency, more support than raw freelancing.

One shift worth internalizing before you choose. AI coding tools have made coding faster and cheaper—but the throughput gain has shifted the bottleneck downstream. When output doubles, review and accountability become scarce resources. That reframes what you’re buying from any of these routes: a correct technical decision and a named owner who stands behind it.

And in case of Lemon.io, you also get your Python developer onboard fast—with no headache on extra vetting, document work, and negotiations on developer payments.
