Head of Go-To-Market / Commercial Co-Founder
Moonsong Labs
London, UK
Posted on Nov 20, 2025
The company
Memco is building the memory layer for AI agents. Agents today are stateless — they forget everything between sessions, can't learn from past interactions, and have no way to share context across tools or teams. Our product, Spark, fixes that. We've already demonstrated 42% performance improvements with shared memory, showing smaller models with Spark outperforming larger models without it.
We’re at seed stage - a small team (3), with active enterprise design partnerships and a growing pipeline of pilots. The technical foundations are strong — now we need the commercial engine to match.
The Role
This isn't a hire. It's a founding team seat.
We're looking for the person who completes the trio alongside our CEO (2x former startup founder - raising $120M+, and former Global Head of AI at a $320B asset manager) and CTO (former Amazon Alexa Lead Scientist). You'll own the entire commercial side of Memco — strategy through execution — and have genuine ownership of the company's trajectory.
You won't be "reporting in" and waiting for direction. You'll have a seat at the table from day one, shaping company strategy, influencing product decisions, and representing Memco to the market. In return, we expect you to be the person who wakes up thinking about pipeline, pilots, and revenue — so the rest of the team can focus on building the best product in the space.
We'll structure equity and compensation to reflect the seniority and commitment this role demands. If you're the right person, we want you to have real skin in the game.
Why now
The AI agent market is moving fast. We have the technical product and the enterprise relationships — but we need someone who can turn design partnerships and early pilots into revenue and signal into a scalable commercial engine. The right person here doesn't just accelerate Memco; they shape what it becomes.
If this sounds like you, or you know who it should be - hit apply or reach out.
What You'll Own:
- The full commercial motion. Pipeline generation through to signed pilots through to repeatable revenue. Design partners, enterprise, mid-market — you figure out what works and you run it.
- Every customer conversation. Discovery, demos, pilots, commercial negotiations. You are Memco to the market. No six-day response times — you're the person who replies in five minutes because you know someone in San Francisco is trying to eat your dinner.
- Go-to-market strategy. Build on what exists, but make it yours. Outbound, community, partnerships, PLG — you design the playbook and then you execute it.
- Positioning and narrative. Work with the founders to refine messaging, ICP, and competitive positioning as the AI agent space shifts underneath us. You're close enough to the market to know when our story needs to change.
- The bridge between market and product. Translate customer signal into product priorities. You sit between buyers and engineering and you earn the trust of both sides.
What you'll bring:
- Sold developer tools, AI/ML platforms, or infrastructure software to technical buyers — and can point to the deals to prove it
- Built pipeline from zero at an early-stage company (Seed–Series B). Not inherited a team and a CRM full of leads
- Can hold a technical conversation with developers and platform engineers. You don't need to write code, but you need to understand APIs, integrations, and how developers evaluate tools
- Operator, not just strategist. You set up the CRM, write the sequences, book the meetings, run the demos, close the deal. You don't need a team to be dangerous
- Comfortable with ambiguity and moving fast. You've done the scrappy early-stage thing and you liked it
- Sold into AI/ML teams, platform engineering, or DevOps organisations
- Background in community-led or product-led growth alongside direct sales
- Experience at companies like LangChain, Vercel, Supabase, Warp, LaunchDarkly, PostHog, Snyk — or similar dev tools at a similar stage
- Existing network in the AI/agent ecosystem
- Closed $50K–$500K+ ACV deals with enterprise or mid-market
- You've been a commercial co-founder or founding GTM leader before and want to do it again with stronger technical co-founders behind you
- What won't work here:
- Pure strategist who wants to define the motion but not execute it
- Needs a large team, SDR support, and marketing budget before they can be effective
- Corporate sales background only — hasn't lived the early-stage reality
Must have:
Strong signals:
Perks and Benefits:
- 100% Remote
- Flexible vacation policy
- Continuous learning & development
