Founding Marketing Lead

Founding Marketing Lead - Open Mercato (20k PLN B2B | Remote (PL/EU))

Full-time | First marketing hire | Main market: USA

We built an open source ERP/CRM that developers actually star. 1,250+ times so far. 130+ contributors, 25 partner agencies, first enterprise customers paying. Nobody is doing marketing full-time. That's the job.

What is Open Mercato

An AI-supportive ERP/CRM foundation framework. TypeScript, Next.js, open source. The philosophy: 80% is ready, you build only your edge.

Agencies build client projects on it. Enterprises license our proprietary modules on top.

Behind it stands a founding team of four, with two exits behind them (Divante, EV ~$65M; Callstack, EV ~$125M). We just closed a ~$1M round.

The product grows on GitHub without ads. Imagine what happens when someone finally pours fuel on it.

What you'll own

• Everything with the word "marketing" in it. Seriously.
• Positioning and messaging. One clear story for three audiences: developers, agencies, enterprise buyers. The main battlefield is the US market.
• Content engine. Blog, case studies, comparison pages ("Open Mercato vs X"), launch posts. You write most of it yourself, with AI leverage.
• Video, lots of it. Product walkthroughs, launch videos, talking-head content in English. You're comfortable on camera and behind the script.
• Community and GitHub growth. Stars, contributors, Discord/X presence. Developers smell fake devrel from a mile away. Don't be fake.
• Partner co-marketing. 25 agencies want to sell projects on Open Mercato. Give them ammo: campaigns, materials, joint case studies.
• Leads and enterprise sales support. Our Enterprise Software Package (4 proprietary modules) is the long-term revenue driver. You generate the leads, mostly in the US, and arm sales with materials that close deals.
• The basics done well. Website, SEO, newsletter, webinars, conference presence, analytics.
• Year one goal: a repeatable marketing machine, from the first repeatable channel to numbers we can plan against. You define the metrics with us, then you own them.

You're a fit if

• You have 2+ years in B2B software marketing, including open source and enterprise software. You know how community turns into contracts.
• You know the US/global market. You've marketed software to American buyers and you get how they buy.
• You write in English at a level where founders stop editing your drafts.
• You're happy on camera. Recording a lot of quality English video is a feature of this job, and you like it.
• You sit between devrel and business marketing. You can demo a framework to engineers, then explain ROI to a CEO.
• You're wired for lead generation. Marketing here exists to feed enterprise sales, and you measure yourself by pipeline.
• You're AI-native. Agents, automation, content pipelines.
• You ship. Draft today beats perfect next month.

Nice to have

• You've marketed to agencies or through partner channels.
• You know the e-commerce/ERP world (Medusa, Odoo, commercetools - these names mean something to you).
• You've done devrel or developer marketing at a dev-tools company.
• Polish. Helps with the team, never required for the job.

What you get

• Real influence. You're the first marketing person, you set the playbook.
• Direct work with founders who built and sold companies before.
• Salary + equity. Ground floor of an open source company going global.
• Remote, async-friendly, zero corporate theatre.
