About Shash Tandon

Head of Sales at Proton

Hi, I'm Shash and I have 15+ years of experience in B2B SaaS sales, customer success, and go-to-market leadership. I scaled a sales team from 1 to 10+ at Proton, drove 125% net revenue retention as a Senior Enterprise CSM and built go-to-market functions from scratch as advisor. I mentor GTM professionals through the two hardest jumps in the career: individual contributor to team lead, and team lead to senior leadership, plus the move into GTM from somewhere else entirely.

Sessions with Shash Tandon

• Career Growth: IC to Team Lead & Beyond (30 min): For GTM, sales, and customer success professionals working through a specific move: building the case for a promotion to team lead, stepping into senior leadership, managing people who used to be your peers, or moving into GTM from a different background entirely. I've spent 15+ years hiring, promoting, and building teams in B2B SaaS, most recently scaling the sales team at Proton from 1 to 10+. Come with a real, specific situation, not a general "give me career advice" ask, and we'll work through it directly.
• Team Lead to Senior Leadership (30 min): For team leads and managers working toward VP, Head of, or senior leadership roles. The jump from running a team to running a function needs a different kind of credibility than the one that got you here, forecasting and board-level reporting, org design, hiring at scale, and influence across product, marketing, and finance rather than just your own team. I've spent 15+ years building and scaling revenue teams, most recently as Head of Sales at Proton. Come with a specific situation, a role you're targeting, a gap you know you need to close, and we'll work through it directly.
• Career Change: Into GTM, Sales & CS (30 min): For people moving into sales, customer success, or GTM from a completely different background. The hardest part usually isn't lack of ability, it's not knowing which of your existing skills genuinely transfer and which gaps are real. I've hired into these roles for 15+ years, including building go-to-market functions from scratch as an advisor at Apify and Resistant.ai, so I can tell you plainly what actually gets someone hired versus what just feels important. Come with the specific role or company type you're targeting, and we'll map what transfers and what doesn't.
• Managing Former Peers as a Manager (30 min): For new managers whose team includes people who were their peers last month. This is one of the most specific, least-talked-about transitions in a GTM career, the relationships don't have to break, but they won't stay the same by default either, and most new managers find that out the hard way. I've hired and promoted people into exactly this position multiple times over 15+ years in B2B SaaS. Come with what's actually happening on your team right now, not a hypothetical, and we'll work through it.
• Corporate to Startup Career Move (30 min): For professionals with a long enterprise or corporate career, in any function, not just sales or GTM, who are trying to move into a startup or scale-up and don't know how to position themselves to a founder or CTO instead of an HR screening process. I haven't worked inside a large corporate myself, but I've spent 15+ years hiring for, selling into, and building startups, so I know exactly what a founder or CTO is actually listening for when someone from a traditional background pitches themselves. This is a newer area I'm actively testing, so come with your specific situation and we'll figure out together whether this is genuinely useful for you.
