Peter showed us how enterprise sales really work - from procurement to contract negotiation. This gave us the confidence to close POSCO’s agentic workflow pilot.

why they chose OUTSOME

Real-time clarity and founder insight.

“Outsome compressed our learning curve by years. In just days, our ICP became crystal clear, our outbound started converting, and our pricing finally made sense. Outsome’s founder feedback is hands-down the smartest decision we made this year.”

Hyunji R.

CEO & Founder, Fitculator

“As a YC founder, I rarely see programs that understand early-stage velocity this well. Outsome doesn’t give generic advice, we give operator-level direction you can execute that same afternoon. Many Korean founders finally get the global-standard coaching they’ve been missing.”

Olof M.

Outsome Mentor, Co-Founder of Alixia (YC W22)

“Founders think their bottleneck is strategy—it's usually pressure. Outsome trains founders to operate under load. By the end of US Track, they pitch cleaner, decide faster, and execute with the calm of someone who’s been tested.”

Ajay J.

US Track Mentor, Former U.S. Navy SEAL

"I joined both Founder Sprint and the US Track because Outsome compresses years of U.S. learning into weeks. Peter’s enterprise sales coaching—from procurement to pricing psychology—was something you can’t find in books or MBA programs. The program saved me from multiple wrong hires and gave me a U.S.-ready narrative that actually resonates."

Go C.

Founder, MarkAny (HBS Graduate)
