^redacted‌ BizBuySell has the most robust deal flow, albeit with plenty you’ll skip right over. It’s good for discovering the listings and often I’ll see the broker name and then find their website and request info / trigger an NDA through there as opposed to directly in BizBuySell. Knowing your focus area in NYC you should also check out Baton Market they have decent stuff that comes up and they don’t always cross post to BizBuySell. For listings on Baton you can sign an NDA on their platform per listing and immediately see a data room + seller interview questions which I find to be very helpful (covers what I often have to ask other sellers in an initial seller meeting).

As a sell-side Advisor, I usually connect my CIM to the associated platform (Axial, BizBuySell, Dealstream, etc) and the CIM is forwarded to the potential Buyer upon completion of an NDA.
