Co-Founder

AI AGENTS ARE ENTERING PRODUCTION. MOST COMPANIES STILL DO NOT KNOW WHEN THEY ARE WASTING MONEY. HELP US SELL THE LAYER THAT TELLS THEM WHY. Costile is an AI agent diagnostics platform for companies building with AI agents. It shows teams which agents are healthy, which are burning budget, what caused the issue, and what action to take next. The product is live. The problem is real. Now I’m looking for a commercial co-founder who can help turn early product validation into customers, pipeline, positioning, and repeatable sales. This is not a normal sales hire. You would help shape the company from the beginning: who we sell to, how we position the product, which buyers care most, how we run outreach, and what enterprise customers need before they trust us. You’ll work directly with me, the technical founder. No layers, no politics, no pretending the playbook already exists. We need to build it.

WHAT YOU’LL OWN

• Go-to-market strategy — define the first ICPs, buyer personas, messaging, channels, and sales motion.
• Outbound sales — build and run targeted outreach toward AI-heavy startups, SaaS companies, consultancies, and enterprise teams using agents.
• Customer discovery — speak with CTOs, product leaders, founders, and engineering teams to understand pain, urgency, budget, and buying process.
• Enterprise sales process — qualify leads, run meetings, follow up, handle objections, and help move interested companies toward pilots or paid plans.
• Positioning and packaging — turn technical product value into language buyers immediately understand.
• Partnerships — explore relationships with AI consultancies, agencies, and teams helping companies deploy agents.
• Commercial product input — bring market feedback back into the product roadmap so we build what customers will actually pay for.

WHAT I’M LOOKING FOR

• Experience with B2B sales, ideally SaaS, infrastructure, developer tools, AI, or technical products.
• You understand long sales cycles and know that enterprise buyers need trust, clarity, proof, and follow-up.
• You are comfortable selling something early, where not everything is polished and part of the job is learning what resonates.
• You can write strong outreach, run discovery calls, and think strategically about positioning.
• You are motivated by ownership, equity, and upside rather than a fixed corporate path.
• You care about building something from zero, not just optimizing something that already works.
• Fluent English is required. Danish is a plus.

Nice to have

• Experience selling to CTOs, engineering leaders, product leaders, or founders.
• Experience with AI, SaaS, cloud, observability, DevOps, data, or technical infrastructure.
• You have helped bring an early-stage product to market before.
• You understand enterprise procurement, pilots, security concerns, and stakeholder mapping.
• You can contribute beyond sales: pricing, positioning, partnerships, fundraising, hiring, or customer success.

WHAT I VALUE

People who take initiative before being asked. People who can turn a vague opportunity into a concrete next step. People who follow up. People who are honest about what is not working. People who care more about learning fast than looking right. This probably is not for you if:

• You need a finished sales playbook before starting.
• You only want to sell a product with existing brand recognition.
• You dislike technical products.
• You are uncomfortable with uncertainty.
• You expect a large team, big budget, or polished internal processes from day one.
• You want a traditional employee role rather than a true co-founder setup.

THE SETUP

Role: Co-founder. Location: Copenhagen preferred, remote is also fine. Stage: Early-stage, product live. Compensation: Equity to be negotiated, with vesting over 5 years. Team: You would work directly with me, the technical founder. Product: AI agent diagnostics, cost visibility, haywire detection, alerts, audit logs, and enterprise reporting for companies deploying AI agents.
