Startup Incubators and Accelerators in Toulouse: The Guide [2026]

Toulouse, a winter morning, in the Montaudran district. Beneath the century-old Latécoère halls, where aircraft were assembled back in the 1920s, deeptech startup founders are hard at work on prototypes in AI, space, and low-carbon energy. This is no coincidence: Toulouse ranks third among French cities for startup density in specialized sectors, driven by aerospace (Airbus, CNES) and deeptech. From Nubbo (a regional incubator with a €50,000 repayable advance) to Bizlab by Airbus (a global aerospace accelerator), more than twenty organizations support founders across Occitanie. This guide reviews the best incubators and accelerators in Toulouse in 2026 and explains how to apply.

The Toulouse startup ecosystem in 2026

Toulouse, capital of aerospace and deeptech

When people think of startups in France, Paris comes first. Then Lyon, Bordeaux. Toulouse often ranks lower in generalist listings. Yet in aerospace, space, deeptech, and AI, the "pink city" plays in a league of its own. The reason is simple: Airbus, CNES (the French National Centre for Space Studies), Thales Alenia Space, and dozens of research labs have been based here for decades. This concentration creates a unique breeding ground for specialized B2B startups.

Occitanie is home to more than twenty incubators and accelerators covering aerospace, digital, and social innovation (source: Les Échos Entrepreneurs). This dense network lets founders find the right kind of support, whether their project involves space propulsion or the circular economy.

French Tech Toulouse and La Cité (Halles Latécoère)

French Tech Toulouse brings together the players in the ecosystem: startups, investors, large companies, and public institutions. The movement runs monthly gatherings hosted by an ecosystem member and makes national programs like French Tech Tremplin and French Tech 2030 easier to access.

The physical symbol of this momentum is La Cité. Opened by the Occitanie Region in the former Latécoère halls in Montaudran, this 9,000-plus-square-meter site has become the beating heart of innovation in Toulouse. Co-working, meeting rooms, a 200-seat conference hall, a Fablab, a restaurant: everything is designed so young companies can grow without friction. It is also where Nubbo, the region's leading incubator, set up its offices. The result: incubated startups rub shoulders every day with other entrepreneurs, investors, and experts.

Tech and deeptech incubators

Nubbo (Occitanie regional incubator, 3 programs, €50,000 advance)

Nubbo is the mission-driven incubator of the Occitanie Region, founded in 2000 and led by Anne-Laure Charbonnier. It targets high-potential tech and B2B startups. Its positioning: support founders from pre-incubation all the way through to a Series A round.

The offering is built around three programs:

Pre-incubation: to test the economic viability of an idea. A first filter before full commitment.
Incubation (12 months): personalized coaching, targeted workshops, funding for external services through a repayable advance of up to €50,000, and introductions across the regional ecosystem.
Acceleration (6 months): aimed at more mature or high-potential companies. The goal: grow commercial activity or close a Series A round, with a further €50,000 in support.

In March 2026, five new startups joined Nubbo: Kepplair Evolution (a European water bomber), Swan-H (low-carbon ammonia), Vecteur (AI-driven space design), Alyzai (operational AI for industry), and Practicle.ai (AI-powered compliance). Each one reflects the incubator's deeptech focus.

Why is it the first choice for a tech startup in Toulouse? Non-dilutive funding (a repayable advance, no equity stake), a home base at La Cité, and direct access to the Occitanie ecosystem.

Bizlab by Airbus (aerospace and space startups)

Are you developing technology for the aerospace industry? Bizlab by Airbus is the only accelerator in France that opens the doors of a 130,000-employee group. Launched in 2015 in Toulouse, the program has since expanded to Hamburg, Bangalore, and Madrid. Its hybrid concept: accelerate external startups and Airbus intrapreneurs side by side over a six-month program.

Since its creation, Airbus BizLab has accelerated more than 90 startups and nearly 70 internal projects, including seven spin-outs valued at €104 million in total. Startups gain access to Airbus coaches, technical and business experts, networking, and co-working spaces.

The program has recently shifted toward a "startup engagement" and company-building model, broadening its scope beyond traditional acceleration. For a founder in aerospace, space, or defense, it is a one-of-a-kind springboard to a first world-class industrial customer.

TBSeeds / Toulouse Business School

TBSeeds is the incubator of TBS Education (Toulouse Business School), open to the school's students and alumni. It has supported nearly 150 projects since its launch. The approach is educational but hands-on: more than 50 hours of group workshops, individual coaching from specialized consultants, and full logistical support (equipped offices, databases, meeting rooms, a podcast and video space).

TBSeeds also operates on the Paris and Barcelona campuses, with remote support available. For a student or recent graduate looking to launch a first company, it offers a structured setting backed by a network of more than 300 founders and business buyers from TBS over the past 25 years.

Impact and social-economy incubators

Incoplex Toulouse (INCO Entrepreneurs, social/environmental impact)

Incoplex Toulouse is the accelerator dedicated to startups with strong social and environmental impact, run by INCO Entrepreneurs (formerly INCO Incubators). The program lasts nine months, is entirely free, and takes no equity stake. A rare model in the ecosystem.

The first cohort, launched in December 2022, selected 12 startups committed to the environmental and social transition in Haute-Garonne: inclusivity, soft mobility, low-carbon solutions, social connection. Support includes strategic guidance from the INCO teams, group and individual training, fundraising support from INCO Ventures, impact-measurement coaching, and workspace in the heart of Toulouse.

If you are building an impact-driven project and want solid support without giving up equity, Incoplex is the most competitive program in Toulouse in this category.

Première Brique (social innovation, backed by Toulouse Métropole)

Première Brique is the social-innovation incubator jointly run by Toulouse Métropole and France Active MPA Occitanie. It is aimed at founders offering an innovative product with strong societal impact and the potential to create 5 to 10 jobs within three years.

Support covers proof of concept, service design, commercial and financial strategy, and connections to the local ecosystem. The incubator regularly launches calls for projects (the seventh was under way in 2022). Its strength: institutional roots and access to local public-sector markets through the Toulouse Métropole network.

Alter'Incub Occitanie (social economy, free program)

Alter'Incub is the national network of social-innovation incubators run by the cooperative movement. In Occitanie, it operates two branches (Pyrénées and Méditerranée) and offers a structured nine-month program: group sessions (market research, business model, governance, funding, legal) and individual support.

The program is free and open to anyone with a social-innovation project, whether entrepreneurs, collectives, associations, or professionals in career transition. The first 2026 cohort was welcomed in January. For a project in the social and solidarity economy, Alter'Incub offers a proven framework with more than ten years of experience.

Specialized incubators

Le Semoir / Purpan (food and agriculture)

Are you working on a food or agriculture project, from production to market? Le Semoir is the incubator of the Purpan engineering school, launched in the summer of 2018. It supports Purpan students and recent graduates in building companies tied to life sciences, agriculture, and food.

It is a niche incubator, rooted in Purpan's century of expertise in agronomy. Founders benefit from the school's network of engineers and its applied research. An obvious choice if your startup touches on food, precision agriculture, or food processing in Occitanie.

Toulouse Bar Association Incubator (legaltech)

Launched in June 2017, the Toulouse Bar Association Incubator is dedicated to innovation in the legal field across the Occitanie Region. It targets legaltech projects led by lawyers or non-lawyers seeking to transform legal practice: document automation, access to justice, management tools for law firms.

It is a niche incubator, but Toulouse, with its law schools and its concentration of firms, offers fertile ground for legaltechs. The program connects founders to the bar's network and to the region's legal professionals.

La Mashine (platform + expert network)

La Mashine describes itself as a "Startup OS": a structured online platform combined with a network of hand-picked experts to help founders go from idea to recurring revenue. Founded in 2024, the organization claims more than 200 projects supported.

The approach is pragmatic and execution-focused: time-boxed steps, concrete deliverables, coaching from experts across a range of fields (strategy, tech, sales, finance). La Mashine is aimed at founders who want to move fast and test in the field without getting bogged down in theory. Its hybrid format (platform + human) sets it apart from traditional incubators.

Ethics Biotope (ethical projects)

Ethics Biotope is the incubator launched by Ethics Group from its offices in Blagnac. Across 1,000 square meters of dedicated space, it hosts around fifteen young companies that have reached a key stage in their development. The positioning: to offer a supportive, innovative environment, halfway between the classic incubator and full independence.

The incubator draws on ten local partners and offers twice-monthly expertise days (the "Starter days"), access to an in-house design and video agency, free services (a law firm, a chartered accountant, Google Cloud), and active networking. Startups such as Gisaïfa (aerospace data visualization), Digikare (health data), and Samares Engineering (engineering consulting) have all been through the program.

How to choose your incubator in Toulouse

Selection criteria (aerospace/deeptech vs. generalist, stage, equity)

Not all incubators are equal, and the best choice comes down to three criteria:

Your sector. If you are in aerospace or deeptech, Nubbo and Bizlab by Airbus are the obvious picks. For social impact, Incoplex or Alter'Incub. For food and agriculture, Le Semoir. For legaltech, the Toulouse Bar Association. For a generalist or digital project, La Mashine or Ethics Biotope.

Your stage. An idea still in the testing phase? Nubbo's pre-incubation or Le Starter by La Mêlée. A working prototype and first customers? Nubbo's incubation or Incoplex. Already growing and chasing a Series A? Nubbo's acceleration or Bizlab Airbus.

Equity. This is the criterion many founders underestimate. Nubbo works through a repayable advance (no dilution). Incoplex and Alter'Incub are free and take nothing in return. Other organizations ask for an equity stake. Check this point before you sign.

A quick comparison of Toulouse programs

Here are the main organizations to compare:

Nubbo: 12-month incubation + 6-month acceleration, €50K repayable advance, tech/B2B, no equity.

Bizlab Airbus: 6 months, aerospace, access to the global Airbus network, no equity.

TBSeeds: variable, TBS students/alumni, free, educational.

Incoplex Toulouse: 9 months, social/environmental impact, free, no equity.

Première Brique: variable, social innovation, backed by Toulouse Métropole.

Alter'Incub: 9 months, social economy, free.

Le Semoir: variable, food/agriculture, Purpan students/graduates.

La Mashine: variable, generalist, platform + experts, 200+ projects.

Ethics Biotope: variable, growth-stage companies, 10 partners, Blagnac spaces.

Preparing your application

Three elements come up again and again in the selection criteria of Toulouse incubators:

A clear problem and an identified market. Selection committees want to see that you have talked to potential customers, not just read market studies. Nubbo and Incoplex place particular emphasis on field validation.
A complementary team. A lone technical founder will struggle. Incubators look for pairs or trios with complementary skills (tech, business, domain).
Scaling potential. This is what separates a startup from a small business. Can your model grow beyond the region? Organizations like Nubbo and Bizlab explicitly look for this potential.

Practical tip: apply to several organizations at once. Call-for-project schedules vary, and each program has its own criteria. A rejection from Nubbo does not mean a rejection from Incoplex.

FAQ

What are the best incubators in Toulouse?

The three most recognized organizations in Toulouse are Nubbo (Occitanie regional incubator, tech/B2B, €50,000 repayable advance), Bizlab by Airbus (global aerospace accelerator), and Incoplex Toulouse (impact startups, free). For students, TBSeeds (TBS Education) is the go-to. The right choice depends on your sector, your stage of development, and your tolerance for dilution.

How do you join Nubbo?

Nubbo recruits its startups through regular calls for projects. Visit nubbo.co to check the upcoming application dates. The process involves submitting an application, an initial screening, and then a pitch before a selection committee. If your project is chosen, you join a cohort with 12 months of support and up to €50,000 in a repayable advance.

Are there aerospace-focused incubators in Toulouse?

Yes. Bizlab by Airbus is the reference accelerator for aerospace startups. Launched in 2015, it has accelerated more than 90 startups across its four global sites (Toulouse, Hamburg, Bangalore, Madrid). Nubbo also supports deeptech startups tied to aerospace and space, such as Kepplair Evolution (a water bomber) and Vecteur (AI-driven space design).

What is the difference between an incubator and an accelerator?

An incubator supports projects in the creation phase: from idea to first product, with a focus on structuring (business model, market validation, first rounds of funding). An accelerator steps in later, once the product already exists, to speed up commercial growth or prepare a fundraise. In Toulouse, Nubbo offers both (12-month incubation followed by 6-month acceleration), while Bizlab Airbus is a pure accelerator (6 months for startups with an existing product).
