Keysender helps vendors distribute digital products-game codes, gift cards, software licenses-across multiple platforms with minimal friction. Think of it as the connection between a vendor’s inventory and the marketplaces where they sell.

Example: A game-key vendor lists on Shopify and marketplaces like Kinguin and Eneba. Keysender auto-delivers keys to buyers, syncs inventory counts across channels, handles refunds, and logs everything for support. Vendors avoid manual sending, overselling, and support back-and-forth, while keeping more margin thanks to our low credit-per-distribution model.

We’re hiring our first dedicated sales hire to build a repeatable vendor-acquisition motion. You will run the show, own the sales vision, set the strategy, and execute. You’ll have autonomy, and the expectation is you know what you’re doing.

The mandate

Our Ideal Customer Profile (ICP) exists but is still evolving. You will find the value, refine the ICP, and build a qualified pipeline-especially in video games, keys, and broader digital goods. We are bootstrapped and generating revenue, but we’ve never had a formal sales function-there’s clear untapped potential.

Responsibilities

• Own vendor acquisition end to end: prospect, qualify, pitch, close, and hand off to onboarding.
• Define and iterate ICP using win/loss signals, roles, inventory types, margins, and channel mix.
• Build the engine: outreach workflows (email, social, calls/DMs), lightweight collateral, and clean CRM processes from zero to repeatable.
• Manage conversion and early vendor health; surface expansion opportunities.
• Track the market and position Keysender vs. Gumroad, SendOwl, Automater, Easy Digital Downloads, and adjacent spaces (e.g., eSIM/Andalu).
• Collaborate closely with the CEO (onboarding and customer success) and with developers in Ukraine, Poland, and Palestine.
• Lead with ownership: set the sales vision, establish targets, and be accountable for results.

Qualifications

• Sales, outreach, or business development experience in SaaS or digital products.
• Supply-side/vendor acquisition experience for a platform or marketplace.
• Comfort setting up greenfield sales processes and lightweight tooling.
• Domain familiarity with video game keys, digital codes, or similar distribution (highly valued).
• Data-driven, organized, succinct communicator; self-starter who moves from talk → test → iterate.
• Operates with autonomy and accountability; can architect the plan and execute it.

Why Keysender

• Aligned pricing: low credit-per-distribution model instead of ~5%+ commissions, so vendors keep more margin and we win when they do.
• Real impact: first sales hire shaping strategy, ICP, and growth story while working directly with the CEO.
• Bootstrapped with revenue: proven product, no formal sales to date, and room to grow.
• Lean, global, pragmatic team with remote flexibility.

Compensation

• Base (full-time): 2,000 USD per month. Flexible for the right person based on experience and impact.
• Part-time: possible, with likely conversion to full-time.
• Incentives: performance-based upside (% of revenue from vendors you bring in).
• Growth: path to build and eventually lead the function.
