Michael Castellano and Garrett Schaefer have been moving at a dizzying rate all week, probably all month, perhaps since arriving at GigTank in late May after coming from Silicon Valley, where making a living, particularly of the startup variety, demands breathtaking stamina and a steadfast belief that you’re The Next Big Thing.

It’s a steamy mid-July afternoon, but Co.Lab’s offices are cool. The room is cramped and buzzing with a quiet energy, like the pressure from a storm before it cracks open the sky. Demo Day, Gig Tank’s denouement, is less than a week away, on July 28, when startups get a chance first to woo investors and then to win over the public.

Finishing a salad, Castellano, the 30-year-old CEO of Engajer, consults a local filmmaker on video production for one of his company’s clients, Providence College. Garrett Schaefer, Engajer’s 31-year-old project manager, taps away at a keyboard. Co.Lab is home base for 14 startups from across the country going through its business accelerator program, GigTank.

“Here’s what comes to mind for me: a virtual tour of the athletics department,” says filmmaker Robert Ashton Winslow, one of many local human resources Co.Lab has recruited to help the startups. Castellano listens. The clock is pushing 1 p.m., when the Engajer duo is scheduled to meet with their mentor Tony Perri.

A 20-second walk takes Castellano and Schaefer to Co.Lab’s conference room. Perri comes in a minute later. Talk starts swiftly regarding spreadsheets, payment methods and DocuSign. Order forms and invoices.
