Overview NYC B2B is a New York startup community built around a Tuesday newsletter that lists the week's best events for founders, operators and investors, and its 2026 media kit reported a 54.6% open rate over twelve months on a list of more than 15,000. Around the newsletter it runs monthly in-person events, dinners and meetups, and a community group chat of about 1,600 members split into sub-groups for Pre-Seed and Seed founders and investors, FinTech, Healthcare, and Bootstrapped and Indie SaaS. The list was built over two years of curating those rooms, one founder at a time. On site Each Tuesday issue carries one Primary slot above the fold, a 100 to 150 word advertorial that NYC B2B writes in its own voice from the advertiser's brief, with one image and one link, and one Secondary slot of 40 to 60 words placed mid-issue among the event listings. The advertiser approves the copy before it ships and gets a performance report within seven days. Some issues go deeper: in August 2026 NYC B2B sent The Pre-Seed/Seed List, 30-plus B2B founders raising at the time, with decks, traction and raise terms. At the events, a sponsor is named in the room and in the WhatsApp group, and is carried on the event page and the pre- and post-event emails. Audience The community's own count of who is inside: founders backed by a16z, Accel, Antler and Hustle Fund; operators at Hebbia, Ramp, Brex and Rho; and investors from Google Ventures, Lightspeed, CRV, Primary Venture Partners, Foundation Capital, 2048 Ventures and Forum Ventures. Readers subscribe for the event calendar, so the newsletter is how they decide which rooms to be in that week. Track record Across 139 placements in the 18 months before its 2026 media kit, the most repeated advertisers were Deel eight times, Attio and Morning Brew seven times each, Superhuman AI, The Rundown AI and Gamma six times each, and HubSpot five, many of them booked through the beehiiv ad network. Event sponsors have included Notion, Gamma, Nike, Artisan and Confluence VC. Brand presence Sponsors buy single sends, four-send runs for a launch, or an annual partnership of 52 consecutive Primary slots that comes with category exclusivity on the Primary position, a quarterly review of opens and clicks, and first refusal on renewal. Event partnerships run at three levels, from a spot on the event page up to access to the event sign-up list and a feature in the newsletter. Booking takes about two weeks from brief to send.
