Pro is at parity with the dominant Singapore tutoring AI - same monthly number. We're not undercutting on price; price isn't the wedge. The wedge is depth, configurability, transparency. If we priced lower, we'd signal "cheaper alternative," which is the wrong frame for a product built for the people who actually engineer their own learning. Parity says: the value is comparable, the substance is different.
Free is invitation-only because it's a relationship signal, not a marketing channel. Most consumer products use a free tier to maximise top-of-funnel - get as many sign-ups as possible, convert what you can. We use it to build a relationship with the first hundred serious learners we choose to onboard personally. Fifty interactions a month is enough to study seriously with Haiku, not enough to substitute for Pro. The constraint is part of the offer.
There is no third tier.No "Enterprise - talk to sales" placeholder. Institutional pricing is a Wedge-2 conversation that gets formalised when the tuition-centre pilot validates, not a marketing-page promise we can't yet deliver on. If you're a tuition centre, a JC, or a school that wants to white-label, we'd rather have the conversation directly than pre-build a tier we'd have to explain away later.
