About
Übungszeit is a platform for German learners to practise with an AI tutor named Helfen.
We built it out of our own frustration. My partner and I are from India, and we struggled to find consistent ways to practise German. So we thought, why not have a tutor available whenever you need one? Helfen can spot your mistakes, help you practise speaking, and support you with reading, listening, and writing.
That’s how Übungszeit came to life. We’re building it with genuine care for German learners and hope it makes practising German a little easier and more accessible.

Pick from nine recurring-revenue models, not one
Most SaaS founders default to a flat monthly seat fee because it's the only model they've seen. Steal from the Automatic Customer's nine recurring models — including the insurance model (customers pay to never think about compliance, backups, or uptime). The right pricing model can double LTV without changing the product. (John Warrillow, The Automatic Customer.)
We were pre-seed investors in Supabase which I think the company's done an incredible job of really leaning into what's happening in AI... the speed at which they ship features, they ship a new feature every single day and so they I think they set the bar for what product velocity should look like.
Supabase Ships A Feature Every Day — That Velocity Is The Bar For Product Teams Now
Jeff's biggest portfolio win highlight is Supabase — not just for the category dominance, but for the velocity standard they've set. A new feature every single day. He frames this as the new bar every product team should measure itself against, calling out that founders who overthink before shipping are losing ground as markets move faster than ever.
There's a play for whatever you're stuck on.
