Congrats to both teams. As a side note, last summer my startup joined Angelpad's accelerator program.. during that time I reached out to @alexsalazar with a laundry list of questions about B2D sales strategy and how he was thinking about the difference and similarities to a traditional b2b sales team structure. He was incredibly supportive and willing to share knowledge and his experience! Thanks again Alex!
Congratulations, it takes a lot of work and time to get this far and launch a set of polished features like this.
Consumer identity offers a very large market segment to sell to and is growing very quickly as an area of focus in enterprises that provide technology to earn dollars from their customers. For those of you unfamiliar with identity management, think of loginbox as twilio for authentication. Historically, companies like Janrain and Gigya have dominated this segment and have focused on selling into Marketing teams with IT as a supporting buyer. Companies like OneLogin are building consumer identity features like this to compliment their internal SSO and provide unification of identities across external and internal user groups.
The name of the game is uptime, be prepared to handle any and all conversations/questions around your architecture, technical operations, strategic decisions to support uptime, and what makes you unique.
Identity is based on open protocols, SAML, OpenID Connect, JWT's etc.. so products start to look very similar, differentiation is difficult but still possible, you'll need to craft your story early or find yourself constantly answering "How are you different from vendor X?".
The payments integration looks great. Companies like segment.io and zapier have proven that ubiquity of integrations can provide huge wins for end users of your product. Start thinking about which ISV's will help propel you into customer bases you wouldn't be able to reach otherwise!!
