Our Team


Indraneel Mukherjee
Founder & CEO

Indraneel loves to apply mathematical insights to solve hard real life problems. Prior to LiftIgniter, he worked in a small team at Google that pushed the boundaries of machine learning research and infrastructure by building one of the world’s largest personalization engines. Ever the geek, he participated in major programming competitions in high school, and went on to get a PhD in theoretical machine learning from Princeton. His research in boosting can be found here. He won the “Outstanding Student Paper” award at NIPS 2010 and had the high honor of an invitation to lecture at the same conference. In his spare time, he enjoys running and playing soccer.


Adam Spector
Co-Founder & Head of Business

Excited about building & creating, Adam joins LiftIgniter from Henge Docks where he was Chief Operating Officer. Adam previously ran his own social data science company, and did business development at Clearwell Systems, an e-discovery company that sold to Symantec for $400m. Before moving to California, Adam worked at Neustar, a trusted, neutral provider of real-time information. Adam holds a JD & MBA plus dual-majored with minor in undergraduate from the University of Miami and Vanderbilt. In his free time, Adam can be found scuba diving (he’s a board member of the Coral Restoration Foundation), reading, and skiing.


Vipul Naik
Head Data Scientist

Passionate about math since childhood, Vipul has won top medals, multiple times, at the prestigious International Math Olympiad, and holds a PhD in Math from the University of Chicago where his thesis was in group theory. His work in machine learning involves applying powerful math tools to achieve immediate real world impact. At LiftIgniter, he is developing cutting edge algorithms for massive datasets that provide dramatic improvements in cost as well as performance. In his spare time, he enjoys contributing to Wikipedia, reading about economics and psychology, and composing music.


Eric Johnston
Software Engineer

Eric enjoys the challenges that come when merging the mathematics of machine learning with the technical problems of building high performance, distributed systems. At Stanford, he double majored in physics and electrical engineering before focusing on machine learning for his masters degree. Prior to working at LiftIgniter, Eric built out a distributed platform for analyzing and classifying massive numbers of malicious files at FireEye. Outside of work, he enjoys rock climbing and biking and trying not to twist his ankle.


Eugene Lee
Software Engineer

Eugene likes math…enough to finish BSc. in Applied Math and BA in Pure Math at Brown University. He started programming in high school at a University lab in Korea Advanced Institute of Science and Technology, where he developed Android applications related to Ubiquitous Computing. Eugene lived throughout Denmark, Korea, and Rhode Island until he came to San Francisco Bay area and found an awesome home at LiftIgniter. Outside of work, Eugene likes playing video games and watching animations. He plans on going outdoors in the near future.


Yonathan Randolph
Software Engineer

Yonathan likes to make things more efficient and dive in to get to the bottom of problems. He finds infrastructures (and their speed & scalability) fascinating. Prior to Liftigniter, Yonathan made data capture programs at Acuitus and worked on book search at Google. He holds a BS in Electrical Engineering and Computer Science from the University of California, Berkeley. He loves coupons and deals and cooks a fair amount when time allows.

Our Advisors

David Blei

David Blei is a Professor of Statistics and Computer Science at Columbia University. His research is in statistical machine learning, involving probabilistic topic models, Bayesian nonparametric methods, and approximate posterior inference algorithms for massive data. He works on a variety of applications, including text, images, music, social networks, user behavior, and scientific data.

David earned his Bachelor’s degree in Computer Science and Mathematics from Brown University (1997) and his PhD in Computer Science from the University of California, Berkeley (2004). Before arriving to Columbia, he was an Associate Professor of Computer Science at Princeton University. He has received several awards for his research, including a Sloan Fellowship (2010), Office of Naval Research Young Investigator Award (2011), Presidential Early Career Award for Scientists and Engineers (2011), Blavatnik Faculty Award (2013), and ACM-Infosys Foundation Award (2013).


Tony Jebara

Tony Jebara is Associate Professor of Computer Science at Columbia University and Director of Machine Learning Research at Netflix. His research intersects computer science and statistics to develop new frameworks for learning from data with applications in social networks, recommendation, spatio-temporal data, vision and text. Jebara has founded and advised several startups including Sense Networks (acquired by, Evidation Health, Agolo, Ufora, MagikEye, and Bookt (acquired by RealPage NASDAQ:RP). He has published over 100 peer-reviewed papers in conferences, workshops and journals including NIPS, ICML, UAI, COLT, JMLR, CVPR, ICCV, and AISTAT. He is the author of the book Machine Learning: Discriminative and Generative and co-inventor on multiple patents in vision, learning and spatio temporal modeling. In 2004, Jebara was the recipient of the Career award from the National Science Foundation. His work was recognized with a best paper award at the 26th International Conference on Machine Learning, a best student paper award at the 20th International Conference on Machine Learning as well as an outstanding contribution award from the Pattern Recognition Society in 2001. Jebara’s research has been featured on television (ABC, BBC, New York One, TechTV, etc.) as well as in the popular press (New York Times, Slash Dot, Wired, Businessweek, IEEE Spectrum, etc.). Esquire magazine named him one of their Best and Brightest of 2008. Jebara will be General Chair for the 34th International Conference on Machine Learning (ICML) in 2017and was a Program Chair for the 31st International Conference on Machine Learning (ICML) in 2014.

I’ll Be Back: The Return of Artificial Intelligence: “Behind much of the proliferation of AI startups are large companies such as Google, Microsoft Corp., and Amazon, which have quietly built up AI capabilities over the past decade to handle enormous sets of data and make predictions, like which ad someone is more likely to click on.”

Siri Is Savvier, but Still Not Smarter Than a Fifth Grader: “Siri and other virtual assistants are designed for a more useful purpose: To reduce the time mobile users spend performing everyday tasks.”
LiftIgniter official press release/launch: “LiftIgniter dramatically increases website visitors’ click through rates with automated personalized recommendations for additional content at every interaction point.”
Customer Engagement Through Personalization Heads to Next Level in 2016: “We expect personalization to go to the next level in 2016. Websites and apps will be forced to personalize more as competition grows even stronger. Time is a zero sum game and each shopper (or user) has a multitude of options. If your site or app is unable to show users exactly what they want at the right moment, then they will leave and find a competitor who does.”
Creating a personal experience: Misconceptions, why data is a critical element : “Personalizing the retail consumer experience is a must for retailers given what shoppers and potential customers have come to expect given personal experiences with social networks, mostly notably Facebook.”

LiftIgniter prides itself on our team.

First and foremost – that means a group of people who enjoy spending time together. We work hard but we’re also friends. Second – brains. It’s almost cliched to say but we truly only want to work with the best. We push each other and expect you, as our new teammate, to push us too.

At the same time, a few extra points in improvement can mean millions in incremental revenue, and the difference between success and failure. So we innovate, at the cutting edge. Our current team of ex-IMO, IOI, Phds from MIT, Stanford, Berkeley, Princeton love the challenges. If you’re excited by the problem and team, we should talk!

Key requirements:

  • Strong background in linear algebra, analysis and statistics
  • Very strong software design skills
  • Solid foundations in algorithms and data-structures
  • Good performances in IMO / IOI / ACM-ICPC a plus
  • PhD in Math / Statistics / Machine learning a plus
