About us

Insider One is the #1 platform that brings everything marketing and customer engagement teams need in one place so they can reach their peak potential and become unstoppable. 

Our story began with six desks and a vision to create a single platform to make industry-first technologies and emerging channels accessible to marketers worldwide. Today, Insider One is powered by 1,500+ team members representing 50+ nationalities across 30+ offices.  With AI at its core and an integrated Customer Data Platform (CDP), Insider One unites data, personalization, and journey orchestration across the most extensive set of natively supported channels, including WhatsApp, SMS, Email, Web, App, and Site Search. 

We recently raised one of the largest funding rounds in the industry, a $500M Series E led by General Atlantic. We are backed by top-notch investors, including Sequoia Capital, QIA, Riverwood, and Endeavor Catalyst, and trusted by 2000+ customers from high-growth startups to the most prestigious Fortune 500 companies such as Samsung, Nike, L’Oreal, Singapore Airlines, Nestlé, Nissan, Lenovo, Puma, IKEA, Allianz, Domino's, and the list goes on.

Insider One was congratulated for becoming one of the only woman-founded, women-led B2B SaaS unicorns in the world. Loved by customers, recognized by analysts, we are the only vendor recognized as the #1 leader in all the capabilities marketing and customer engagement teams need. Don’t just take our word for it — see for yourself. We consistently outperform and continue our leadership, and the results speak for themselves.

From day one, Insider One’s mission has not only been to build a world-class product company, but also to create one of the most socially progressive technology communities in the world. Through our social responsibility initiatives like 100 Social Responsibility Projects, AI Training for Teachers, Code Academy, SheCodes, SheLeads, and SheMarkables, our community has committed to scaling its impact on our communities across 30+ countries, driving initiatives in health, education, farming, animal rights, and increasing women’s representation in STEM.

Behind all these achievements is an exceptionally talented, visionary team of overachievers that moves fast and agile, creating cutting-edge products, and focuses on making an impact. If you want to be a part of this journey, just keep reading.


We are looking for a driven, strategic Sales Development Representative based in Madrid to support our Southern Europe market. You will play a critical role in building and managing outbound pipeline, partnering closely with Account Executives to identify, engage, and qualify enterprise prospects. This is not a high-volume dial-and-smile role. It’s a strategic, account-based position where quality, personalization, and business acumen matter.

 

  • Execute strategic outbound prospecting across targeted enterprise accounts through personalized cold calls, emails, LinkedIn, and creative multi-channel sequences
  • Build relationships with prospects by researching their business challenges and tailoring outreach around Insider One’s value, not just features
  • Qualify and develop sales opportunities using an account-based approach, passing sales-ready leads to Account Executives for progression
  • Collaborate cross-functionally with AEs, Marketing, and leadership to identify key accounts, refine messaging, and align on go-to-market strategy
  • Leverage martech tools such as 6sense, Salesloft, and Salesforce (SFDC) to prioritize accounts based on intent signals, engagement data, and ideal customer profiles
  • Contribute to ABM campaigns and demand generation initiatives, understanding how SDR efforts fit into the broader marketing and SaaS buying process
  • Continuously learn and grow. You’ll join regular training sessions and work alongside experienced sales professionals and leaders who invest in your development
  • Experience in Sales Development, Demand Generation, ABM, or Marketing
  • Bachelor’s degree in Marketing, Business, or comparable education/experience (top university graduates and referrals preferred)
  • Good exposure to the e-commerce and/or digital marketing space
  • Excellent oral and written communication skills in both Spanish and English 

    • Beyond credentials, here’s what sets top performers apart:

  • Proactive self-starter with high initiative, critical thinking, and a bias toward action
  • Highly organized and efficient, able to develop and execute against an evolving plan while managing multiple workstreams
  • Marketing innovation mindset with hands-on experience in mainstream martech (6sense, Salesloft, Salesforce, generative AI tools, etc.)
  • Strategic thinker with exceptional attention to detail in execution. You see the big picture and sweat the small stuff
  • Strong project management, time management, prioritization, and organizational skills
  • Clear and confident communicator who can present new ideas, strategy, and campaign plans to internal stakeholders
  • Proven ability to achieve results working cross-functionally with sales and marketing teams
  • Team player who thrives both collaboratively and autonomously
  • Strong problem-identification and objection-resolution skills
  • A strong phone presence and comfort dialing dozens of calls per day to US-based prospects
  • Flexibility to adapt quickly in a fast-paced, startup environment
  • Be part of a diverse team that’s as global as it gets — where every voice is heard and 50+ nationalities build together.
  • Level up with internal trainings covering AI fundamentals, coding, foreign languages, and a wide range of personal development skills.
  • Feed your curiosity with access to Spotify, LinkedIn Learning, Blinkist, MasterClass, and CloudGuru.
  • Become a Shareowner through our eligibility-based “ESOP” and own a piece of what you build.
  • Help build the team you want to work with and enjoy rewarding referral bonuses.
  • Opportunities to give back to your community through volunteering and purpose-driven social impact projects.
  • From global retreats to team-building activities, expect year-round events that turn into lifelong memories.
