EARLY STAGE INVESTOR FOR
technology startups focused on
data, analytics, and AI

OUR ROLE

Successful Angel Investing is really difficult so we work extremely hard with entrepreneurs to build customer traction early. We are typically the first investor in a SaaS company and many times we bring in additional investors although that is not our mission. 

INVESTMENT FOCUS

B2b companies with recurring revenue that sell to large retailers and brands with an emphasis on marketing technology that drives real-time decision making through analytics and data, and artificial intelligence.

TARGET INVESTMENT

Mack Capital is usually the first investor in most of its portfolio companies but definitely in the first round of financing. The typical investment in that initial round is $100k-$300k. Mack Capital participates in most follow-on rounds of financing until the enterprise reaches $150mm to $200mm.

Ralph is not just an investor but he becomes a friend, confidant and loyal person that you ALWAYS want on your side. He is always available to lend a helping hand with advice and will always get his hands dirty. He considers no project beneath him and brings an energy that is unmatched to work with. The availability that he shows to his companies is hard to even understand unless you have been in that experience. He shows up when he says he will and makes sure to always bring energy. He has been indispensable in my career and to the team at Sightly. We thank him for all the contributions and we know that he will be so important throughout every stage of our future. Companies would be lucky to have him on their side.

Lots of people can provide capital, lots of people can provide advice, but Ralph does so much more for every company he has invested in. As an advisor to several companies Ralph has invested in, I can tell you every one of them have only the best things to say about Ralph.

Bryan Eisenberg – OneSpot, Sightly

Good customer introductions, and good talent introductions,
what more can you want from one of your angels. Stays involved but doesn’t meddle.
Thanks for everything Ralph.
