BIO
I've had the incredible opportunity to experience early and growth stage startups from various perspectives. I've been a founder leading Helloguru, where we launched a no code tool and successfully raised $1.5 million in capital. Prior to that, I served as Chief of Staff for the CEO at Drift, where I honed my skills in startup growth and product development. I also had the opportunity to incorporate cutting-edge technologies from startups in ABinBEV.
