What are the responsibilities and job description for the GTM Engineer position at Harper (YC W25)?
The Problem
36 million businesses in America need insurance—it’s not optional. 77% are underinsured. 40% have no coverage at all. The distribution system failed them: too slow, too opaque, too confusing.
Over 90% of commercial insurance is still human-led. We’re building the inverse: 90% AI-led, pushing toward the higher 90s. Not by patching legacy workflows—by building AI that makes humans more effective, improves the customer experience, and eliminates friction at every step.
We’re adding ~1,000 customers per month. We’ve grown 100x since last year. We’re looking to do even more this year—and that’s why we’re hiring.
To grow that fast, we need to understand—with precision—what’s working, what’s not, and why.
The Thesis
This is a founding role. You'll own the insight layer behind growth from day one—shaping how marketing dollars are spent, how campaigns are optimized, and how we scale. Every model you build, every experiment you run, every insight you surface becomes company DNA. Winning in 6-12 months means measurable revenue impact AND a growth analytics engine that runs itself.
The Role
You're a commercial data scientist who sits at the intersection of marketing, analytics, and product—but make no mistake, this is a growth role, not a research role. You work closely with the Head of Marketing to answer the questions that matter: what's working, what's not, why, and what to do next.
You work directly with founders. No committee. No approval chain. You surface it, you influence it, you own the outcome.
What You’ll Do
Data talks. Narratives walk. If you prove things instead of just believing them—send your resume and an example of analysis that drove a business decision.
Compensation Range: $130K - $190K
