What Sherman Street Capital buys
Sherman Street Capital is a New York investment firm that says it has direct access to capital and partners with founders, managers and employees. Managing partners Danny Baker and Grant Perelman met at Northwestern. Its site names no fund and no size range. In practice it builds platforms and adds to them.
Its active platform is Atlas Power Partners, formed in 2025, which Baker and Perelman co-founded and Sherman Street backs. Atlas buys residential generator and electrical service companies and says it is looking across the country. It added Always On Generators in Southwest Florida in 2025, Trademark Electric in North Central Florida in 2026 and Boyland Electric in Maryland in November 2026. Atlas does not publish a minimum size. Owners can keep running the company with Atlas handling the back office, or plan a handover on an agreed timeline. Sherman Street's homepage also lists Squire Dental, a dental group Perelman co-founded. An owner of a generator or electrical business would most likely meet the firm through Atlas.

Greymont’s take
How Sherman Street Capital fits a seller
Sherman Street suits an owner of a residential generator or electrical service company who wants a partner to carry the back office. Through Atlas, an owner can stay in charge or plan an exit, and Atlas says most companies keep their names. Boyland Electric's founder stayed on as president in November 2026. Owners speak directly with the leadership, and Atlas says a deal usually takes weeks or months rather than years.
There is little public detail behind that. Sherman Street names no fund, size range or investors, and Atlas is young, with three companies. Ask where the equity for each deal comes from, how much cash is paid at closing, whether you would hold shares in Atlas, and what happens to those shares if the platform is later sold.
Questions owners ask
Is Sherman Street Capital connected to Atlas Power Partners?
Yes. Atlas's November 2026 release says Danny Baker and Grant Perelman of Sherman Street co-founded Atlas, which formed in 2025, and that Sherman Street backs the platform. Sherman Street's own website does not mention Atlas.
What companies does Atlas Power Partners buy?
Residential generator and electrical service companies that sell, install or maintain backup power. It says it is seeking partners across the country, and it does not publish a minimum size.
Does the owner have to leave after joining Atlas?
No. Atlas describes two paths: keep running the company or step away on an agreed timeline. At Boyland Electric, founder Doug Boyland stayed on as president after the November 2026 deal.
What size company does Sherman Street Capital look for?
It does not say. Its site names no size range or fund, and Atlas says it leaves out minimums because it would rather talk with the owner first.
