About OpenSpindle
Built From the Shop Floor Up
OpenSpindle was born from a problem Tom Petrini experienced firsthand: finding the right manufacturing partner shouldn't be so difficult.
Our story
Built From the Shop Floor Up
Pick your length. We won't be offended.
After more than 20 years in manufacturing, from global supply chains to running his own CNC fabrication business, Tom Petrini saw the same problem from both sides: finding the right manufacturing partner was too hard, while capable shops had capacity to fill.
He met Bryan Petro through competitive cycling. Bryan had helped scale GetMyBoat into a global marketplace, connecting fragmented supply with demand.
Together, they founded OpenSpindle to bring that marketplace model to manufacturing — connecting people who need parts made with qualified shops that have the capabilities and capacity to make them.
Born from the shop floor. Built to connect manufacturing.
What we believe
Principles behind the marketplace
Sourcing shouldn't be a second job
Tell us what you are building and we match your parts to the right manufacturers, so you can stay focused on your product, not chasing quotes.
Trust is the whole point
Quality, price, timelines, NDAs, and escrow, built into every job, so you are never guessing about a shop you have never met.
Built by both sides
We have sourced manufacturing for a hardware startup and run a shop ourselves. The marketplace is built around how both sides actually work.
A network, not a directory
Hundreds of independent manufacturers across processes and geographies, matched to your job, not a list you have to sift through.
The team
Two founders, one mission
Tom Petrini
Co-Founder
20+ years across the manufacturing value chain. Started at SAP building supply-chain systems for Fortune 500s. Founded Evive, a hardware startup that raised $10M+, holds patents, and deployed nationwide at 99.9% uptime, personally onboarding manufacturing partners worldwide. Then founded Siena Built, a CNC and fabrication shop he grew for over a decade and sold in 2024. Tom has lived every side of the build — enterprise systems, product development, and the shop floor.
Bryan Petro
Co-Founder
OpenSpindle is his fourth marketplace. As the first employee and eventually CEO of Getmyboat, Bryan grew it into the world's largest boat rental and charter marketplace, connecting millions of boaters to hundreds of thousands of boats across 184 countries, before selling the company in 2022. Earlier, he drove iSport.com past a million users on organic growth alone. He knows how to build the trust and liquidity a two-sided marketplace needs to scale.

We're just getting started
We're building the sourcing partner we wish we'd had: a place where a company or hardware startup can bring their whole bill of materials and get matched with manufacturers they can trust, from first prototype through full production.
Our goal is simple, connect the world's manufacturing capacity with the companies that need it. Whether you're sourcing custom parts, run a shop that wants better work, or just want to help shape where this goes, we'd love to hear from you.
