November 4-5th, 2021

The Big Transaction is a two-day, single track virtual conference dedicated entirely to the art of payments engineering. Join us in November and learn the best strategies, architectures, tips, and tricks for building high quality payment systems that work at scale!

Our Conference Focus

Surviving Payments

Building a payment system is no easy feat given the ever-changing needs and regulations for businesses. Yet almost all companies need to deal with these challenges in some form. As such, we want to create a series of talks focused on the monitoring, testing, and architectural strategies that will ensure you can always sleep at night after shipping.

Our conference will feature 12 speakers, with each talking about their own experience on wrangling complexity, solving real-life scenarios, and creating robust and flexible payment systems.

Would I Like This Conference?

The Big Transaction is all about sharing knowledge and exploring how to create better payments and billing systems. We feel strongly that the best way to do this is to bring people together in a common space to talk and learn from each other. If any of the examples below sound like you, we think you would really enjoy this conference:

  • Your company has an antiquated payment system you want to improve, but you're not sure where to start.
  • You work in the payment space and want to learn the latest in payments engineering methodologies and best practices.
  • You find the constant changing in payment laws and compliance in different parts of the world difficult to follow and are looking for clarity.
  • You love working in payments and want to share your thoughts and learn from others to take your skillsets and ideas to the next level.
  • You prefer conferences where you are intentionally given time and opportunities to build real connections with like-minded developers in the payments space.

We Are Now Fully Virtual!

Our dream was for The Big Transaction to be an in-person conference. But with the rise of COVID Delta variant, we no longer felt we could put on an event in November and still keep our attendees safe. And yet, our planned speaker lineup turned out to be so strong that canceling the conference altogether felt like it would be a huge waste of knowledge to the payments engineering community.

So we made the call and turn The Big Transaction into a virtual conference. And though we'd love to meet everyone in person, running a virtual conference comes with some unique benefits. Specifically, without the overhead of a venue, we can pass those savings in ticket costs back to you! As such, our General Admission ticket prices have been reduced to just $30.00!

Our conference will be hosted on AirMeet, which provides many features and options for attendees, speakers, and sponsors alike. We recommend taking a look at this video to get an idea what it's like from the attendee perspective and their features to directly engage with other attendees, speakers, and sponsors.

Refund Policy

We support refunds until October 15th, 2021.

Code of Conduct

All attendees must agree to follow our Code of Conduct to ensure our conference is safe and welcoming for everyone.
