The modern alternative to Zendesk, Freshdesk, Intercom, and Front. Connect your database and Stripe. Our AI support agent resolves tickets across email, forms, and other channels.
We grew our last product, Martin, to 100k users. At one point, we'd get 50 support requests every day:
"How do I use this feature?"
"Can I get a refund?"
"I can't log into my account."
I had to hire a virtual assistant in the Philippines to reply to users and solve billing issues.
I had to use Zendesk, which was built 20 years ago and designed for a VP of Support, not a founder.
None of this made sense, so we built our own modern, AI-native support platform. We integrate with your database, knowledge base, and Stripe, and our AI auto-prepares resolutions to every ticket.
We’ve already replaced Intercom, Zendesk, Zohodesk, Helpscout, and Freshdesk for many fast-growing companies in YC.
If you’re building a B2C or self-serve B2B product, give it a try or book a demo at: https://letterbook.ai
P.S. Unlike Zendesk, which takes days to set up (a friend literally hired a consultant to teach him), Letterbook takes 5 mins. And if you need help, you better believe we have top-notch customer support!
the database + stripe integration is what makes this actually useful, most ai support tools just search a kb but can't answer "why was my charge different this month" without pulling real customer context. :)
curious how it handles tickets that genuinely need a founder decision though, does it escalate automatically or does it just draft and wait?
I'm exactly your ICP (as the founder who is replying to every single CS ticket)!
I actually chose Zendesk because it also supports a Help Center. Does Letterbox also come with a Help Center? If not, what are the usual ways you see your users setting them up and connecting to Letterbox?
Went through the signup flow. The 15 minutes to first resolved ticket claim on the landing page is the right hook, that's exactly what a founder dealing with support volume wants to hear.
The gap is that Signup asks for the organization name before showing any evidence that the 15 minutes is real. For a founder evaluating whether to commit, that's a small friction at exactly the wrong moment. The stronger move would be showing one resolved ticket in a demo state before asking for anything, let the claim prove itself before the founder has to name their organization. What does drop-off look like between landing page and completed signup?
Congrats on the Launch, this is one of those products where I wish I knew about it way sooner!!
Congrats Dawson!! That's incredible that it can even process the refunds on stripe as well. Excited to try it out!!
Support tooling for founders is usually an afterthought - either paying for Intercom before you have revenue, or handling everything manually through email threads. The AI angle makes sense here. What does Letterbook do when it doesn't know the answer - does it hand off to you, or does it try to figure it out?
The Stripe + database integration is what sells this for me. Running a B2B SaaS with self-serve billing, and 60% of our support tickets are "where's my invoice" or "cancel my subscription" — exactly the kind of thing AI should handle autonomously. How does the AI handle edge cases where it's not confident? Does it escalate to a human automatically or does it attempt a response anyway?
Good one @darweenist I want to ask if there is a provision for seamless migration from existing support platforms to Letterbook. This will be a game changer for companies with large user database on their existing platforms instead of starting over. The homepage could also do with some relevant FAQs. Good luck with the launch.
Letterbook is the best support platform ever. We love it at Respan. Congrats on the launch Dawson and team!!
Dawson this is so real. We're two founders building WTMF and support has been one of those things that just quietly eats your time. Never felt like Zendesk was made for teams like ours.
The auto-prepared resolutions thing is what caught my eye. Going to try it out. Congrats on the launch and honestly 100k on Martin is a tough act to follow, excited to see where Letterbook goes.
Hey Dawson, that line about Zendesk being built for a VP of Support, not a founder, really stands out. Was there a specific day where you were drowning in those 50 daily tickets, juggling a VA and a tool that felt way too complicated, and thought why do I need enterprise software just to answer basic questions?
Congrats on the launch! Support is one of those things that sneaks up on you, and can eat away at your hours. Once you connect Stripe, how much customer context does the AI actually pull in when it's drafting a reply?
