About OTOT

Our Team

• 

  CEO

  Tian Xia

  

  Tian brings the best of both worlds—the strategic rigor of major consulting firms and the scrappy, get-it-done speed of start-up life. Having led federal technology modernization projects and built products from the ground up at nimble startups, Tian knows what it takes to move fast without cutting corners. OTOT was founded with exactly that mentality: big-firm expertise, start-up hustle.

  • Fluent in ‘solutioning,’ ‘ideation,’ and other made-up consulting words, but the results are very real.
  • Has used the word, “framework,” so many times it lost all meaning, yet keeps building them, breaking them, and making them better anyway.

  Senior Manager

  Ann Foley

  Ann uses her operator mindset and strategic perspective to build plans and make sure they actually get executed. She’s led automation efforts, written executive speeches, fixed broken processes, and often steps in to figure out what the problem is in the first place. Her work at OTOT drives improved audit performance and large-scale financial corrections (adjustments exceeding $1B). She’s known for cutting through noise, aligning the right people, and getting things moving, without overcomplicating it.

  • PMP, Six Sigma, Tableau—yes, all the certifications you’d expect
  • Comfortable walking into ambiguity and leaving with a plan (and a timeline)
