Jen Foley.

Product leader by trade.
Obsessive investigator by nature.

I've spent 20 years turning ambiguous problems into shipped products — the last six as a fractional PM. Outside of client work, I apply the same instinct for close observation to 57 tomato varieties, the trail network in my backyard, and whatever I'm currently overthinking on Substack.

What I'm building

Client work, community projects, and a few things that started as a hobby and refused to stay one.

Consultancy

Ballast Advisory

Fractional product management for teams that need senior PM thinking without a full-time hire. Recent work spans regulated-industry software, e-commerce, and consumer products — usually somewhere in the messy middle between strategy and shipping.

Jen Grows Tomatoes

57+ heirloom varieties, documented with the same rigor I'd bring to a product roadmap — plus a running experiment in AI-augmented growing and selling.

South Shore Trails

A directory of the trails I actually walk, built because the good ones are scattered across a dozen town websites and nobody had stitched them together yet.

What it's like to work with me

In their words, not mine.

A rare ability to stay calm and clear in complex, high-stakes situations — bringing structure, momentum, and thoughtful decision-making when it mattered most. Any company engaging Jennifer for fractional product leadership will benefit from her experience, judgment, and ability to deliver real progress.

Joanne DomeniconiCo-Founder, The Grommet

She helped us identify and correct several long-standing organizational inefficiencies within the product team and improved the collaboration between product and engineering. I would bring her back in an instant.

Diego ConchaConsulting CTO

As an engineer working with Jen, I always had clear direction for specific tasks as well as a sense of the overall product direction. Stakeholders always had a clear picture of deliverables, timeline, and progress. I would work with Jen again in a heartbeat.

The short version

I've worked product at companies where "ship it" meant a warehouse full of furniture (Wayfair) and companies where it meant a baby registry someone's entire extended family would use (Babylist). Six years ago I went fractional, and haven't looked back — there's something I like about walking into a new team's mess, understanding it fast, and leaving it better than I found it.

That instinct doesn't turn off at 5pm. It's why I've catalogued 57 tomato varieties with more discipline than some product backlogs I've inherited, why I sit on my town's Conservation Commission, and why I can't resist mapping every good trail within twenty minutes of my house. I'm also a longtime food and travel writer, a 30-year South Shore transit rider, and — depending who you ask — either deeply curious or a little too online about all of it.

If you're looking for a fractional PM, start at Ballast Advisory. If you're just curious what a product person does with the rest of their attention, you're already in the right place.
