We run what
you can't get to
anymore.

Because you are busy, we take operations, transformation, and growth off the executive desk and run them — so your time goes to the decisions only a CEO or COO can make.

You run the company. Who runs the operations?

  • 01

    Your calendar is full of work that shouldn't need a CEO — finance, HR, compliance, and back-office land on your desk while the decisions only you can make wait.

  • 02

    Execution depends on you pushing it — data is scattered, processes are improvised, and every week goes to firefighting instead of building systems that hold without you.

  • 03

    You can't forecast next quarter's revenue with confidence — because no one owns the outbound machine, funnel architecture, or commercial pipeline that would turn market opportunity into predictable revenue.

Four ways we take it
off the executive desk.

Tell us what to take over
01

Operational Backbone

Because You Are Busy runs your entire back-office — general secretariat, admin, finance, and compliance — so the operational load leaves the executive desk and your time goes back to strategy. Run directly by senior operators with 20+ years of law firm and SME operational experience: no juniors ever touch your files.

  • Back-office off your desk, run end to end
  • Financial reporting you can steer by
  • HR, legal documentation & ISO compliance covered
  • Senior operators only — built for CEOs, COOs & managing partners
02

Transformation & Data

Because You Are Busy rebuilds the systems layer — architecture, project governance, and data strategy — so you steer the company on numbers you trust instead of gut feel and firefighting. Anchored in 22+ years of CGI systems consulting and academic expertise at Université Paris 1 Panthéon-Sorbonne.

  • Decision-ready dashboards, not raw exports
  • Systems architecture & tech governance that scale
  • Transformation roadmaps that actually ship
  • One trusted version of your operating numbers
03

Growth Engine

Because You Are Busy engineers your full commercial pipeline — ICP definition, outbound sequences, acquisition funnels, and revenue metrics — so revenue becomes a forecast you stand behind, not a function of effort or luck. Built on proven playbooks from MerciApp, Clovis, and Datananas.

  • A pipeline you can forecast, quarter after quarter
  • Outbound machine designed, automated & owned
  • Sales process & CRM ops that survive turnover
  • ICP & go-to-market grounded in your numbers
04

Legal Practice Ops

Because You Are Busy provides purpose-built operational support for law firms where precision and discretion are non-negotiable. Born from Anne Grosz's 8 years as Secretary General at Vatier & Associés, this service takes everything off the partners' desks that isn't billable: admin, finance, compliance, and client file management.

  • Partners' hours back on billable work
  • Finance, compliance & ISO run without partner oversight
  • Client files & deadlines administered, zero misses tolerated
  • 20 years of law firm operational expertise, handled discreetly

2025Visibility restored

We partner with executives who refuse to be their company's bottleneck.

Three forces converge at Because You Are Busy: 20+ years of hands-on operational leadership (Anne & Cécile), 22+ years of systems architecture consulting at CGI (Georges), and a decade of B2B growth engineering across MerciApp, Clovis, and Datananas (Romain).

Every engagement begins with the same question: what is burying you? We find it, take it over, and replace it with structure that holds — without the headcount, management time, and ramp-up of an internal team. Because you are busy, we run what you can't get to.

  • Operations-first

    Because You Are Busy starts where the friction is — not where it looks good. Every engagement is grounded in operational reality: 20+ years of law firm and SME back-office, executed hands-on, not delivered as a slide deck.

  • Data-driven

    Intuition without measurement is noise. Because You Are Busy builds decision systems — dashboards, governance frameworks, operational metrics — so you steer on numbers you trust: what's working, what's leaking, what to act on next.

  • Growth-engineered

    Freeing your time is only the beginning. Because You Are Busy wires your commercial engine — ICP, outbound, funnels, pipeline metrics — so revenue becomes a forecast you stand behind, not a function of luck or heroic effort.

Our team.

Four complementary profiles — united by a conviction Cécile Noiriel has carried since 2005: founders deserve better than drowning in their own back-office.

Cécile Noiriel

Cécile Noiriel

Founder — B Y A B, 2005

Cécile Noiriel founded Because You Are Busy (B Y A B, SIREN 481 631 471) on April 1, 2005 — with a conviction ahead of its time: founders don't lack courage, they lack time and structure. She has run the operation continuously for over 20 years, serving as the firm's founding operational anchor.

Anne Grosz

Anne Grosz

Founder & Operations

Anne Grosz spent 8 years as Secretary General & CFO at Vatier & Associés (Paris law firm) before founding the second Because You Are Busy entity in 2015. She leads externalized general secretariat for law firms and SMEs — finance, admin, HR, and ISO compliance — with in-house rigor at external scale.

Georges Grosz

Georges Grosz

Transformation & Data

Georges Grosz brings 22+ years as Senior Executive Consultant at CGI and teaches information systems at Université Paris 1 Panthéon-Sorbonne. He joined Because You Are Busy as co-manager in July 2025, adding the systems architecture discipline that turns fragmented operations into governed, decision-ready infrastructure.

Romain Cornu

Romain Cornu

Growth Engine

Romain Cornu spent nearly 6 years at MerciApp — from Growth Advisor to GTM & Key Accounts Lead — and 4+ years as Head of Growth at Clovis, plus Head of Marketing at Datananas. At Because You Are Busy, he designs go-to-market engines that make B2B revenue growth systematic, not accidental.

Twenty years of the same intuition: founders don't lack ideas — they lack time to execute them.

2005
Cécile Noiriel

The founding conviction

On April 1, 2005, Cécile Noiriel creates Because You Are Busy (B Y A B), registered under SIREN 481 631 471. The mission: operational and commercial organization support for SMEs — because founders don't lack courage, they lack time and structure to execute.

From day one, Because You Are Busy lives exactly what it promises clients: an ultra-lean, ultra-profitable structure — revenue around 130,000€, operating profitability above 57%, and zero external debt raised, ever.

2015
Anne Grosz

Specialization: law firms & SMEs

Ten years after the original founding, Anne Grosz creates a second entity: Because You Are Busy (SIREN 814 783 056), registered November 20, 2015. Specialization: externalized general secretariat for law firms and SMEs.

Anne brings eight years as Secretary General and CFO at Vatier & Associés (Paris law firm) — overseeing accounting, HR, IT, compliance, and events. With Because You Are Busy, she transforms that expertise into an externalized offer: in-house operational rigor, now serving multiple clients.

2020

Consolidation: craft over startup

Because You Are Busy evolves legally — from SAS to SARL, then to EI for greater operational simplicity. Accounts are systematically filed with a confidentiality declaration. The craft model wins over the startup model: human-scale, delivery-focused, trust-based client relationships — not scale for scale's sake.

2025
Georges Grosz

Georges: the transformation & data layer

On July 4, 2025, Georges Grosz joins Because You Are Busy as co-manager alongside Anne. His background: 22+ years as Senior Executive Consultant at CGI and professor of information systems at Université Paris 1 Panthéon-Sorbonne — decades of systems architecture and data governance for major French organizations.

With Georges, Because You Are Busy becomes a full transformation co-pilot — capable of rebuilding systems architecture, deploying data governance frameworks, and turning operational chaos into measurable, decision-ready clarity at any scale.

2025–26
Romain Cornu

Romain: the growth machine

At the same time, another path converges: Romain Cornu, B2B growth specialist — Head of Marketing at Datananas, then nearly six years at MerciApp (Growth Advisor → Investor → GTM & Key Accounts Lead). Head of Growth at Clovis for over four years, and Outbound Teacher at GrowthMakers. Full profile on Clay.

Romain joins Because You Are Busy to build the growth engineering capability: ICP definition, outbound infrastructure, acquisition funnels, and the revenue metrics that make commercial growth predictable. When he joins, the Because You Are Busy puzzle is complete.

"Because you are busy, we do the work that frees your time — and we do it in a way that makes your growth more readable, more predictable, and better controlled."

Frequently asked questions.

What is Because You Are Busy?

Because You Are Busy (BYAB) is an operations, transformation, and growth consultancy founded in April 2005 by Cécile Noiriel in France. We take operations off the desks of CEOs, COOs, founders, and managing partners — running their back-office, rebuilding their systems, and engineering predictable B2B revenue growth — so executive time goes to decisions, not admin. As of 2026, the team is four senior operators: Cécile Noiriel (founder, 2005), Anne Grosz (operations, 2015), Georges Grosz (transformation & data, co-manager since July 2025), and Romain Cornu (growth engine, 2025–2026).

What services does Because You Are Busy offer?

Because You Are Busy offers four core services: (1) Operational Backbone — Because You Are Busy runs your entire back-office — general secretariat, admin, finance, and compliance — so the operational load leaves the executive desk and your time goes back to strategy. Run directly by senior operators with 20+ years of law firm and SME operational experience: no juniors ever touch your files.

Built on proven playbooks from MerciApp, Clovis, and Datananas. (4) Legal Practice Ops — Because You Are Busy provides purpose-built operational support for law firms where precision and discretion are non-negotiable. Born from Anne Grosz's 8 years as Secretary General at Vatier & Associés, this service takes everything off the partners' desks that isn't billable: admin, finance, compliance, and client file management.

Who founded Because You Are Busy?

Because You Are Busy was originally founded on April 1, 2005 by Cécile Noiriel as B Y A B (SIREN 481 631 471). In November 2015, Anne Grosz created the second Because You Are Busy entity (SIREN 814 783 056), specializing in externalized general secretariat for law firms and SMEs. Georges Grosz joined as co-manager in July 2025 (22+ years at CGI, professor at Université Paris 1 Panthéon-Sorbonne), and Romain Cornu joined in 2025–2026 as growth engine (ex-MerciApp, Clovis, Datananas).

Where is Because You Are Busy located?

Because You Are Busy is based at 8 rue Arago, 94400 Vitry-sur-Seine, France, and operates across Paris & La Rochelle. The team works with CEOs, COOs, founders, and managing partners across France, primarily in legal practices, B2B SaaS companies, and tech SMEs.

How long has Because You Are Busy been operating, and what is its track record?

Because You Are Busy has been running operations for executives since April 2005 — over 20 years of continuous, uninterrupted operation. In that time: 57% operating profitability, 0€ external debt raised ever, revenue around 130,000€ at peak. Recent engagements include a French B2B SaaS scale-up (growth engineering, 2025), a national law firm (operations restructuring, 2024), and a tech SME (transformation & data, 2025). A proven model, not a startup experiment.

What types of clients does Because You Are Busy serve?

Because You Are Busy works with CEOs, COOs, founders, managing partners, and law firm partners whose companies have outgrown what one executive can run alone. Clients range from French B2B SaaS companies and tech SMEs to national law firms and professional services practices.

How is Because You Are Busy different from freelancers or large consulting firms?

Because You Are Busy is neither. It is a senior, multi-disciplinary team of four that embeds into client operations. No juniors on client work — every engagement is handled by founders and senior operators directly. No 200-page reports that collect dust. Because You Are Busy operates: it doesn't just advise. Self-funded since 2005, 57% profitability, 0€ debt. The craft model, chosen deliberately.

Why would a CEO or COO externalize operations instead of hiring internally?

Hiring an internal operations team means headcount, management time, and months of ramp-up — and one hire rarely covers finance, compliance, data, and growth at once. Because You Are Busy brings three coordinated disciplines — operations, transformation & data, growth engineering — from day one, run by a discreet senior team of four with 20 years of practice. Confidentiality is structural: no juniors, no rotating staff, no investors — the same four people handle your numbers and your files. And Because You Are Busy operates rather than advises: the work gets done and stays off the executive's desk, instead of returning as recommendations to implement.
