How leading teams are using Lightster
  • Oz N.
    I’ve been working with Lightster since their earliest days, and they have proven to be an invaluable partner in our work at PMF Studio. Most senior product people know that the hardest, and the most unpredictable, part of user research is recruiting. It always takes longer than you expect, it’s tedious so few people take joy in doing it, and quality is hard to maintain. Lightster managed to take away this headache for a number of our projects, as they deliver to spec quickly and efficiently. I’ve used them across most of our projects in 2023 and 2024, and they’ll continue to be my go to when we need to recruit across both B2B and B2C use cases.

    Compared to other sources we have used to target potential customers for feedback, (UserInterviews,, Lightster is much better at targeting and getting us people able to provide valuable feedback.
  • Cameron Howe
    Product development is a very hard task, especially as a newly launched startup. You want access to a pool of potential customers to come in and get feedback. Often times the ones you do acquire naturally don't want to give this feedback. Lighter has been instrumental for us in talking to customers, hearing their pain points around investing and building a product that fit their needs. We continue to come back throughout our product development lifecycle to access willing new testers for our investment app.

    Baoba team was very happy with the Lightster solution! Their platform has been supporting us in validating new product directions by matching us with professionals working in the insurance industry whom we could interview. The process was easy and we received 5 quality matches to conduct interviews with - Lightster has contributed to our validation process tremendously! I would recommend to use the solution to all startup founders whether it’s seeking to validate product directions or a pivot, conduct ongoing solution validation or simply matching you with relevant advisors!
  • Jaime Aoyagi
    Lightster was a great way to conduct user testing before writing a single code line. With Lighster, I was able to talk to more than ten people within a week to learn more about their WFH dynamics. What impressed me the most is that not only was I able to find users that fit our criteria but also the fact that I was able to talk to them directly through their app. I highly recommend Lightster to anyone looking to gain insights into their market.

    Before Lightster, I had to pay thousands for an external firm to find potential participants and then pay again for gift cards. With Lightster, I get to choose the participants and only pay once… by the minute!
