About OSG
One Strategy Group (OSG) is a leading career consulting firm with a global footprint across the U.S., U.K., and APAC Regions. We specialize in helping ambitious students launch careers at top-tier finance and consulting firms, including Goldman Sachs, McKinsey, Blackstone, Bain Capital, and many more.
Through highly personalized mentorship, a structured and rigorous curriculum, and access to an exclusive network of industry professionals, we empower our students with the knowledge, skills, and confidence to succeed in the most competitive global job markets.
But our mission goes beyond mentorship. OSG is committed to closing the information gap in the recruiting process. We offer tailored strategies, individualized timelines, and hands-on support that reflect each student’s unique background, strengths, and career aspirations. From one-on-one job interview coaching to in-depth career consulting, every student benefits from our customized approach to professional development.
With full-time teams based in both the U.S. and the U.K., we provide global, around-the-clock support. Our mentors are not only professionals at top investment banks, hedge funds, private equity firms, and consulting firms—they are also trained educators selected for their ability to mentor, motivate, and teach effectively. This combination of real-world expertise and coaching acumen ensures that every OSG mentee receives practical, up-to-date, and results-oriented guidance.
We are selective in how we define and measure success. We only count offers for front-office roles with strong full-time conversion potential, excluding off-cycle, unpaid, or non-convertible internships. Despite these high standards, our students continue to earn more elite offers than we can publicly showcase, which is a testament to the integrity and impact of our methods.
At OSG, we don’t believe in shortcuts. We believe in personalized guidance, ethical practices, and results that speak for themselves.
OSG’s Story
Each year, thousands of students aim to break into elite finance, consulting, and business roles—but many fall short. The recruiting process is complex, high-pressure, and often unclear. Due to this, students often turn to career coaches and consulting firms—yet many are met with overpriced, ineffective, or even unethical services.
From “pay-to-intern” schemes to promises of “guaranteed referrals,” these shortcuts rarely lead to real success. They can damage a student’s credibility and long-term career trajectory by bypassing skill-building and violating industry compliance standards.
We founded One Strategy Group to offer a better path, one grounded in integrity, transparency, and sustainable success. Our goal has always been to provide mentorship and strategy that empowers students to earn their achievements the right way. Every roadmap is personalized. Every success is earned.
At OSG, we don’t promise shortcuts. We provide real support, designed to last. Our work is about more than landing a job—it’s about leveling the playing field and redefining what meaningful, high-impact career coaching should look like.
Since 2018, OSG has led the way in premium career consulting. We are known for our unique mentorship model, exceptional success rates, and customized strategies that deliver measurable results.
