Founder's Associate

TL;DR\ Langfuse is looking for a Founder’s Associate (Full‑Time, on‑site in San Francisco or Berlin) to work directly with the three founders—Max, Marc, and Clemens—on both the nuts‑and‑bolts of running the company and on high‑velocity initiatives that unlock our next stage of growth. \ Roughly one‑third of your time will be spent building durable processes (finance, accounting, hiring ops, reporting), while two‑thirds will be devoted to “speedboat” projects such as rolling out a new CRM for sales, launching new billing flows, hiring for and advertising new positions, prepping fundraising materials, and validating new customer segments.

This role is perfect for an ambitious, hands‑on generalist with a technical bent—you’re likely a recent graduate or early in your career—who blends technical fluency (you can use and demo Langfuse) with commercial intuition.

Why Founder’s Associate at Langfuse?

• Ride Shotgun with Marc & Clem: Work day‑to‑day with Marc (CEO, product/marketing) and Clemens (COO, sales).
• 10× Learning Curve: Rotate across ops, product, sales, and finance in a single role
• You Ship: Your projects go live immediately—no ivory‑tower slide decks.
• Own Outcomes: You will see your work move revenue, burn, or product velocity.
  
  

Your Mandate

• Operational Backbone (One Third)
• Finance & Accounting: Stand up lightweight accounting tools, streamline invoicing, manage monthly closes, and prepare investor reports.
• People Ops: Run the end‑to‑end hiring pipeline, schedule interviews, craft JD’s, and ensure stellar candidate experience.
• Investor Comms: Own reporting, draft updates, and keep our metrics data room ready.
• Speedboats (Two Thirds)
• CRM: Implement Hubspot; design pipelines, dashboards, and automation.
• Billing & Pricing: Roll out a better billing process for our Enterprise customers, coordinate with engineering, and validate pricing experiments with customers.
• Market Expansion: Lead quick‑and‑dirty tests of new customer segments—cold outreach, pilot design, aggregate feedback & results.
• Fundraising Prep: You help build the narrative, model the numbers, and assemble materials for our next round.
  
  

You Might Be a Fit If…

• Commercial & Tech Background: Hybrid Skill - You’ve mixed coding with commercial acumen – tell us about this! This could be a side project, a prior role or something else.
• Technical Fluency: You can spin up Langfuse, build a demo with an LLM API, and explain our value prop to a CTO.
• Process Builder: You thrive on turning chaos into a documentation page and sprinkle some Zapier and SQL on top so we can tackle the next problem.
• Bias to Action: You’d rather bring an 80 % solution live today than perfect it over the next quarter.
• On‑Site Mindset: You’re excited to join us in SF or Berlin fully on-site.
• We can sponsor visas for both locations
  

Compensation & Benefits

• Salary: 60-90k EUR or (x 1.4 USD in SF)
• Equity: 0.1% - 0.35%
• Hardware & software of your choice
