Social media

About

NSI supports companies and organisations in designing and deploying their social media strategy, in France, Europe and around the world. Through tailor-made programmes, NSI grows engaged communities and turns social media into a genuine driver of reputation and influence.

Social media plays a central role in building the image of an organisation, company or brand. It shapes how audiences perceive you, carries the voice of your leaders, fuels brand awareness and, in times of crisis, acts as a decisive echo chamber.

Social media: a driver of reputation and influence

We are committed to working with you to define your platform for expression, develop your key messages and turn them into native content designed for each platform and each audience (LinkedIn, X, Instagram, TikTok, YouTube, Facebook, Reddit, etc.). With an international outlook and consultants and directors who are experts across a wide range of sectors (industry, technology, health, energy, finance, services, education, tourism, NGOs, etc.), we craft editorial and creative programmes that give your brand a voice and build connections with your communities.

Our work supports your positioning and growth, and aims to help you gain influence and impact with all your stakeholders. Our mission is to turn your social presence into positive, consistent and engaging communications that enhance your reputation.

What guides us:

  • Supporting, advising and challenging you – in short, being your partner in making social media a strategic asset for your organisation.
  • Helping you address your image, reputation and transformation issues, whether organisational or digital, CSR, employer branding, thought leadership, etc.
  • Building strong, engaged communities by creating genuine platforms for expression through trust, information and emotion.
  • Liaising effectively with all your influence initiatives: media relations, marketing, advertising, influencer marketing, public affairs, internal communications, etc.

Our approach:

  • Define and editorialise your communications through a tailor-made content strategy, adapted to each platform and audience, aimed at reaching your various stakeholders.
  • Act within the framework of a comprehensive and ongoing action plan built in structured stages and combining organic and paid, tailored to your challenges and visibility with a view to achieving impact.
