Legacy

The founder’s story · from the public record

Acme Lock was founded in Cincinnati in 1933 by Herman and Florence Woods and stayed in the Woods family for four generations. For decades it was a downtown fixture: after a 2007 fire forced a move it added a hardware section, and in 2017 the family's Matt Woods reopened the hardware side as Woods Hardware in an 8,000 sq ft space at 125 E. Ninth Street, telling WCPO that downtown's growth meant 'we didn't have a choice but to grow'. Cobalt announcement, May 21, 2025 · WCPO, Jan 2017: Acme Lock and Hardware expands

In December 2020 Tom O'Brian bought the lock-and-door business with a group of partners. He is careful to say he did not start Acme, only that he 'had the privilege of being part of its story'. What he found, he says, was a smaller company whose team had 'a rare ability to tackle complex access challenges' and 'an absolute obsession with taking care of customers'. In the early days, he says, 'we made things happen and kept customers happy through sheer force of will'; the systems came later.

Between 2020 and 2025 Tom and John O'Brian built out the infrastructure and scaled quickly, folding in two Cincinnati shops, Larry's Lock in 2022 and Fortress Safe & Lock in 2024, and growing Acme to 70 people. The company consolidated at a 25,000 sq ft showroom, shop and dispatch centre on Este Avenue and now describes itself as the region's largest team of door and lock technicians and sales engineers, handling everything from safe openings and rekeys to storefront glazing, access control and fire-door compliance under one roof.

By 2024 the O'Brians were looking for a partner to fund the next stage. Tom calls the decision 'one of the toughest decisions I've had to make': the company had momentum, but keeping it up 'would require more resources and infrastructure than we could provide on our own'. Others could have filled that gap, he says, but Cobalt shared the belief that 'if you take care of your people and your customers, the rest takes care of itself'. Tom and John transitioned out gradually; COO Bradley Drury became CEO at close, and Cobalt's Tyler Hoffman called Acme 'among the most well managed operations we've encountered'.

The team

The people who built it

Acme's site has no team page; customer reviews on it name technicians Wayne, Daryl, Dan and a manager, Mike. Cobalt's announcement names Tom O'Brian, John O'Brian (described there as Tom's father) and COO-turned-CEO Bradley Drury; Cobalt's team page adds GM Dan Lumpkin. Founders Herman and Florence Woods and later owner Matt Woods are named in the announcement and 2017 local press. The family rule is applied strictly: Acme's own site lists no family.

The sale

As both sides told it · on the public record
Announced May 21, 2025 By Cobalt (own newsroom) Deal #14 for Cobalt Service Partners Founder left Cobalt, May 21, 2025
What Cobalt Service Partners said

Cobalt announced Acme on May 21, 2025 as its 14th acquisition and third of 2025. Tyler Hoffman said Cobalt was 'thrilled to partner with Tom, John, Bradley, and the Acme team' and called Acme 'among the most well managed operations we've encountered'. Cobalt's company page dates the acquisition to April 2025.

What the founder said

Tom O'Brian said the O'Brians began looking for a partner in 2024 to support ambitious growth that needed more resources and infrastructure than they could supply alone. Other partners could have filled the gap, but Cobalt was 'sharp, driven' with a clear vision and, more importantly, shared his belief that taking care of people and customers takes care of the rest; that gave him confidence Acme's culture, team and legacy were in good hands. He and John transitioned out gradually.

Terms on the record: Nothing public. No price, structure, rollover or earn-out disclosed. (The Blue Book directory lists an annual volume band, but that is a self-reported directory entry, not a release.) Advisors: None named on either side.
