How Startup Tandem Was Born

Startup Tandem was born in 2017 from a vision and a conversation. At that moment Startup Tandem was just an idea, there was no clear business plan. The vision of creating a startup community where startups can support each other became clearer with experience. It was when Alejandra had the opportunity to work for one of the biggest financial consulting companies for startups that it all came together. It was at that moment that she realized the huge gap it exists between price, service and value for these businesses. Startup Tandem, Inc. was created to bridge the gap and to build partnerships. Our mission is to come together as partners to provide the best and most valuable service to the Startup Tandem’s community.
