Definition

Built to Scale is a French-language morning event held on 16 June 2026 at IPGG (Institut Pierre-Gilles de Gennes), home of PC'UP, the deeptech incubator of ESPCI Paris, at 6 Rue Jean Calvin in the 5th arrondissement. It is co-hosted with RAISE Sherpas. The event gathered deeptech CTOs, CEOs and technical leaders to discuss how to grow and structure technical teams as a company moves from research to production and into hypergrowth, part of the wider VivaTech Side Events circuit and adjacent to other AI and Data circuit fixtures such as DeepTech Momentum in Berlin.

The 2026 edition: 16 June at IPGG

The agenda ran a welcome coffee (09:00), a panel discussion (09:15 or 09:30 depending on source) and breakfast networking (10:30). The discussion covered recruiting technical talent, structuring teams, technical governance and maintaining velocity through rapid growth. The event was hosted on site by Célia Peltier and Louise Colin of RAISE Sherpas, with Louise Colin serving as the fund's Startup Program Lead. The Luma registration page recorded 112 attendees signed up by the time registration closed, a figure that corrects an earlier estimate of around 40 carried in a prior verification pass of this fiche; the higher count reflects the actual Luma registration count rather than an early-stage snapshot.

Where it sits in the VivaTech week

The event ran on 16 June, the morning before VivaTech's business programme opened at Porte de Versailles, as one of the practitioner-focused sessions that cluster around the show alongside fellow founder and operator mornings such as Scaling Revenue. Its in-person, French-language format made it a local working session rather than an international showcase, consistent with the VivaTech Side Events pattern of pairing a small number of intimate, practitioner-only formats against the week's larger national nights and investor dinners.

The fourth panellist was listed as "to be announced" in an earlier verification pass; the Luma event page, re-checked at this verification, confirms Julien Vaïssette of Recupere Metals filled that slot.

What the format includes

FAQ · Identity and audience

What is the link with VivaTech?

It is a side event during the VivaTech week, on the morning of 16 June, co-hosted by PC'UP and RAISE Sherpas. It is independent of VivaTech ticketing and sits within the wider VivaTech Side Events circuit of founder and operator mornings.

In what language is the event held?

The event is held in French.

How many people attended?

The Luma registration page recorded 112 sign-ups by the time registration closed, well above the roughly 40 registered captured in an earlier snapshot of the same Luma page. Attendance figures for approval-based Luma events can shift materially between an early snapshot and the final registration count, which is what happened here.

Who is Built to Scale NOT designed for?

It is not designed for: non-French speakers, since the session is in French; the general public, since registration is approval-based; founders outside deeptech, given the technical focus; and those seeking investor matchmaking rather than a practitioner panel on team scaling.

The venue: IPGG, PC'UP Incubateur ESPCI

The event is held at IPGG, the Institut Pierre-Gilles de Gennes, which houses PC'UP, the deeptech incubator of ESPCI Paris, at 6 Rue Jean Calvin, 75005 Paris, in the Latin Quarter. The incubator setting fits a panel and breakfast for a focused audience of technical leaders, and its location places the event inside the same research-to-startup pipeline that produced several of the panellists' companies.

The organiser: PC'UP and RAISE Sherpas

PC'UP is the deeptech incubator of ESPCI Paris, a public engineering and physics school. As of this verification, PC'UP states it has accompanied 54 startups, contributed to more than 2,500 jobs created, supports 128 patents and licenses, and has helped its portfolio raise more than EUR 850 million in funding and grants since the incubator's founding. RAISE Sherpas describes itself as a philanthropic accelerator operating within the RAISE group: it has funded more than 250 startups and associations since 2015, drawing on a network of more than 200 large companies, SMBs and scale-ups, more than 150 mentors and operators, and more than 100 venture capitalists, angels and banks across Europe, all provided free of charge to the founders it supports. The pairing brings together a deeptech research-to-startup pipeline and an early-stage support structure, which is consistent with the panel's own subject: how a small research-origin team becomes an organisation built to scale.

Press interest and media coverage

This is an intimate, approval-based practitioner panel rather than a headline VivaTech fixture, and its media footprint reflects that scale honestly. FrenchWeb, in its roundup of the week's VivaTech side events, listed Built to Scale by name and described its premise directly: "Comment transformer une équipe de recherche en une organisation capable de soutenir l'hypercroissance ? Organisé par PC'UP et RAISE Sherpas, Built to Scale : How CTOs Grow Deeptech Teams That Last réunira CTOs, fondateurs et dirigeants techniques pour partager leurs retours d'expérience sur les défis du passage à l'échelle." This is a listing-style mention inside a broader side-events feature rather than a dedicated article on the panel itself, and no other named outlet coverage of this specific event was found as of this verification. No organiser-attributed quote from the panel itself is publicly available; RAISE Sherpas hosts Célia Peltier and Louise Colin are named on the event listing as the on-site contacts, but no on-record statement from either has been published. Given the event's approval-based, single-morning, French-language format, this modest footprint is consistent with its intended audience rather than a gap in research.

Editorial take

A practitioner morning on the hardest deeptech question: turning a research team into an organisation that can scale, told by four CTOs who have done it.

How to register and what it costs

Registration was free and handled through Luma, subject to host approval. The Luma page recorded 112 attendees registered by the time registration closed, well above the roughly 40 captured in an earlier snapshot of the same page. No next edition of Built to Scale has been announced as of this verification; readers tracking the format for a future VivaTech week should check the VivaTech Side Events index and the Upcoming EMEA events index for a successor listing.

The 2026 edition ran on 16 June 2026, from 09:00, at IPGG, PC'UP Incubateur ESPCI, 6 Rue Jean Calvin, 75005 Paris. A future edition, if organised, would be expected to align with a subsequent VivaTech week, tracked on the VivaTech Side Events page.

What should attendees expect?

A welcome coffee, a French-language panel with four deeptech CTOs, from Spore.bio, Calyxia, EverDye and Recupere Metals, and breakfast networking.

Is this event part of a wider circuit?

Yes.
