IPOLyst

Our Approach

Two constraints shaped every decision. First, no single GMP source could be trusted on its own, so the headline number had to be derived rather than copied from somewhere. Second, nothing could depend on a person remembering to update it: every IPO moves through its lifecycle on its own schedule, and a stale status is worse than no status at all. That pushed us toward deriving state from the underlying dates rather than storing it by hand, and toward automation as the default rather than something added later. We also treated speed as a correctness problem rather than polish, because a page that stalls mid-session is one the investor closes.

The Solution

The platform aggregates GMP from multiple sources and computes a consensus average, surfaced through an interactive chart that tracks day-by-day movement for each IPO so the trend is visible rather than just the current figure. A date-driven status engine derives Upcoming, Ongoing and Closed from real subscription and listing dates, so listings move through their lifecycle without anyone touching them, and a GitHub Actions pipeline refreshes the data hourly through trading hours. One-click deep-links drop investors straight into the registrars' allotment checkers, cutting a fiddly multi-step lookup down to a tap, and an SEO-focused blog on Sanity CMS lets the team publish against high-intent IPO search terms without waiting on a deploy.

Impact

IPOLyst launched in four weeks across twelve screens, and runs without a maintenance rota: status transitions are derived rather than entered, so no one has to be watching on listing day, and the hourly pipeline keeps GMP current on its own. Consensus averaging removed the single-source dependency that made the original brief risky in the first place. Pages are prerendered and incrementally revalidated at the edge from Vercel's Mumbai region, which is what makes it quick enough to check mid-session on mobile, the use case the whole platform is built around. The Sanity-powered blog gives the team an owned channel to compete for IPO search traffic on their own schedule.
