This week: New meetups get their legs under them. And don’t forget about this week’s Startup Grind, which features Clutch CEO Ned Moore.

Maker Entrepreneur Happy Hour & Informal Show and Tell: This new meetup is for entrepreneurs that make and sell physical goods. Alli Blum, who runs a coloring company called Hooley, said she started the meetup to fill a gap: “Things like supply chain, sourcing, and ethical and/or American manufacturing don’t get a lot of play at tech or startup events. Neither does non-ecommerce distribution.” If you’re an entrepreneur who fit into this category, fill out this survey to help shape the meetup. Wednesday, 5:00 p.m. Perch Pub, 1345 Locust Street. Center City. RSVP. Free.
