FAQ
Questions we often get
How long does it take to see results?
The first meetings usually come between week 4 and week 6 — the time to build the database, calibrate the message and launch the first wave. A full B2B sales cycle then plays out over 3 to 9 months depending on the complexity of your offer. We tune the steering to maximise ROI at every step.
What is the difference between "prospecting" and an "outsourced sales force"?
Prospecting stops at booking a qualified meeting — your salespeople take over from there. An outsourced sales force goes further: we qualify, negotiate and move the opportunity forward in your CRM all the way to signature. You choose the scope based on your internal resources.
How do you choose the best prospecting agency?
Choosing a prospecting agency comes down to a few key criteria. • The agency’s clients: an agency with experience of companies like yours (consulting firm, SaaS company…) will adapt its techniques and tools to your specific needs. • Multichannel expertise: some agencies specialise in a single channel (LinkedIn), others take a multichannel approach — better suited to organisations that want to reach their targets through several touchpoints. • Your targets’ profile: if you address senior decision-makers, choose an agency able to combine several channels, especially the phone, which remains a very effective prospecting channel in 2025. • The team’s profiles: depending on your organisation, choose experts who match your needs (Business Developers, Inside Sales, Growth Hackers…) and fit your company’s DNA. • Data intelligence: mastering data is at the heart of sales performance in 2025. Challenge your contacts on their CRM tools and certifications… You would be surprised how unequal agencies are on this crucial topic. • Transparency and reporting: choose an agency that plays it straight and lets you follow results in real time. MESSOR is the ideal agency for consulting firms, service companies and software vendors. We offer a team of experts trained in sales 5.0, made up of young talent or experienced profiles, graduates of top business schools and based in France.
What role does AI play in business development in 2024?
Artificial intelligence (AI), and generative AI in particular, is transforming business development with concrete, varied use cases. Common applications include automatic transcription of interviews and writing and proofreading emails. Going further, AI can use big data from APIs and CRM tools to analyse thousands of LinkedIn profiles and personalise your prospecting campaigns at scale, or summarise thousands of job ads to better understand your targets and their needs. With its dual expertise in business development and advanced data management (APIs, tools, properties), MESSOR designs custom AI solutions to boost your sales productivity and optimise your prospecting efforts.
Do you only work in French?
No. Our team covers FR, EN, DE and IT. We regularly support expansion into DACH, Italy, Benelux and the UK, with team members native to the target countries.
How do you integrate my CRM and tools?
We work in your stack, not ours. HubSpot, Salesforce, Pipedrive, Attio — we plug in and operate from your CRM. We are Make Advanced certified to automate the syncs and enrichment you need.
