Spencer Darr.
Product & Operations Leader Brooklyn, NY AI-Native Operator

I build B2B SaaS from 0→1 — and own the outcome.

The short version: ten years turning messy customer workflows into products people actually adopt, and lately working nearly every seat in the business — product, solutions, support engineering, partnerships, and the commercial model. Equally comfortable writing the spec on day one and owning the P&L on day 365. I've lived inside these integrations, not managed them from a slide.

→ These days I run it AI-augmented — agentic tools let me deliver the daily impact of a small team as a single operator.

What I own

Four things I bring to a growth-stage team — the rare combination is the operator who can do all four.

0→1 Product

Discovery through roadmap, engineering handoff, launch, and iteration — products that get adopted and paid for, not just shipped.

Owns Economics

Pricing, margin, portfolio rationalization, profitability. The GM-track differentiator that's rare in a PM.

Integration Depth

HubSpot, NetSuite, ConnectWise, ERP/CRM — messy enterprise workflows turned into integrations that run like a silent helper, not a fire drill.

AI-Native Execution

Daily, advanced use of AI and agentic tooling to expand what one operator can deliver. The 2026 edge.

Selected Work

Two chapters of professional work — the products I built and owned, and how I operate across the business now — plus two I built on my own time.

Chapter I — I built it

Chapter II — Across the business, AI-augmented

On my own time

Why they're here: the clearest proof of how I think and build — real users, end-to-end data work, honest validation, and shipping discipline — done on my own time, with AI.

How I Work in 2026

Working AI-native isn't just a workday thing; it's how I keep the skills sharp. Here's what I build on my own time.

I learn by building.

The fastest way I know to understand a new technology is to build something real with it. So on my own time, with AI as the pair I learn alongside, I've been teaching myself the things that aren't in the job description — statistical modeling, data pipelines, front-end craft.

None of it was assigned. The projects on the right are what I reach for when the workday ends; each one started as a way to push a new skill until it stuck.

A little of what's playing, screening, and hanging on the wall while I work. Guitarist of 20 years, cinephile, sports diehard, mountain-town transplant.

Let’s build.

Product & operations leadership roles at growth-stage B2B SaaS — PM through Director of Product, and on the operations side, BizOps through GM. If you're building something in that space and want an operator who's lived inside the work, let's talk.
