Commercial Development Intern

About Firsty

At Firsty, we’re on a mission to blow up the boring world of international roaming and become the first telecom provider people actually love. Founded by two Adyen alumni with innovation in their DNA, we’re backed by investors with serious industry know-how and a powerful network. Our buzzing office in the heart of Amsterdam is where creativity, ownership, and fun come together every day.

Firsty APAC launched from Singapore earlier this year. Since then, we’ve been embedding telecom directly into the digital apps people use every day: e-wallets, ride-hailing apps, digital banks, and super apps. With a fast-growing partnership pipeline and multiple launches ahead, this is an exciting time to join the journey.

The Role

This is not a “watch and learn” internship. This is a build-the-engine role. We’re looking for a sharp, resilient, and commercially curious intern who’s excited to support the full partnership funnel, from prospecting and outreach to ops, CRM hygiene, and keeping deals moving.

You’ll work closely with the founders and the commercial team to turn market signals into real conversations and structured revenue opportunities.

What you will do:

Prospecting & Intelligence

• Define and refine our Ideal Customer Profile (ICP) by segment (banks, travel platforms, super apps, etc.)

• Identify target accounts and map out the Decision-Making Unit (DMU)

• Build and verify contact lists using tools like Apollo and LinkedIn Sales Navigator

• Track market news and partnership triggers to create timely outreach angles

• Monitor competitor offerings and pricing signals to strengthen our sales hooks

Sales Development & Outreach

• Set up SDR cadences across email and LinkedIn

• Draft and iterate cold outreach sequences (with a focus on clarity, relevance, and conversion)

• Personalize outreach based on each account’s product and customer journey

• Own the first draft of key external comms (intro emails, follow-ups, partnership notes)

Pitch, Proposals & Sales Ops

• Create and refine pitch decks and one-pagers (client-ready formatting matters)

• Customize proposals and decks by segment, use case, and pain point

• Help run the “CRM police” function: keeping Attio clean, consistent, and up to date

• Support invoicing workflows and payment follow-ups when needed

• Identify bottlenecks in our sales process and suggest automations to speed things up

Who you are:

• Currently pursuing a degree in Business, Marketing, Economics, or a related field

• Strong skills in presentation building, proposals, and deck polishing (you notice misalignment)

• Comfortable with commercial numbers and basic deal economics

• Excellent communication skills (English essential)

• High “figure-it-out” energy: proactive, resourceful, and not afraid to roll up your sleeves

• Thick skin and curiosity: you take feedback as fuel and enjoy improving fast

Why Firsty?

• Work directly with our founders and APAC launch team

• Hands-on exposure to real partnership execution and startup sales operations

• Collaborate with a global, cross-functional team

• Learn and use modern sales tooling (Attio, Apollo, Sales Navigator, Google Suite, Slack)

• Real ownership from day one

• Competitive internship allowance

• Ideal for anyone entrepreneurial and eager to learn how high-growth startups actually scale
