The project and the problem.
End-to-end fundraising platform with investor dashboards, Stripe payments, and global compliance flows.
The Capitalista team needed a fundraising platform that could handle global investors, multi-currency Stripe payments, and a real-time investor dashboard all with the polish that financial users expect.
- Accept global investment in multiple currencies without manual reconciliation
- Give investors a real-time view of their portfolio
- Satisfy region-specific compliance before any money moves
The approach and process.
We built a Next.js platform optimized for trust signals, performance, and a clean dashboard experience that scales with investor count.
- 01
Mapping the Compliance Maze
2 weeksCapitalista's biggest unknown wasn't engineering. It was figuring out what each region actually required before money could move. We sat with the team's compliance advisor for a full afternoon and walked out with a checklist that turned into the onboarding flow's branching logic.
Region-by-region compliance checklist · Currency + payment-method matrix per region · Data model for investors, positions, and documents · Roadmap with the compliance gates marked in red

A Design That Sells Trust
3 weeksFinancial users decide whether they trust you in the first three seconds. We spent more time on the marketing hero, the typography, and the empty-state copy than any other visual decisions in the project. "It looks expensive" was a real, intentional design goal.
Marketing site, dashboard, and onboarding in one Figma file · A type system the client could not break · Empty / error / pending states for every dashboard view · Motion notes. Restrained, never bouncy
- 03
Building the Foundation
3 weeksNext.js with mostly server-rendered pages because investors arrive from Google searches and decide in seconds. We split the marketing site (static, edge-cached) from the dashboard (server-rendered, authenticated) so neither side compromised the other.
Marketing pages on the edge, dashboard behind auth · Session model that survives plan and currency changes · Base UI from the design system · Staging environment that mirrors production exactly
- 04
Stripe, KYC, and the Live Dashboard
4 weeksWe wired Stripe in two layers. The checkout for new deposits and the webhook handler for everything that happens after. The dashboard pulls from the same ledger Stripe writes to, so an investor's view is never more than a few seconds out of date. The KYC flow saves on every field. Investors can close the tab and pick up where they left off.
Multi-currency Stripe checkout (14 countries at launch) · Webhook handler with reconciliation report · KYC flow with progress persistence · Real-time portfolio dashboard + activity feed
- 05
Launch and the Funnel Work
2 weeksWe instrumented every step of the funnel before launch so the team could see, on day one, which step lost the most investors. The first two weeks of data led to copy changes on the deposit page that lifted conversion by a noticeable margin without us writing a line of code.
Production launch at capitalista.info · Funnel instrumented from landing to first deposit · Monitoring + alerting for payment failures · A short ops runbook for the founders

What changed.
A side-by-side of what the client had before we engaged, and what we shipped.
- Investor onboarding ran on email, PDFs, and a Google Form that asked the wrong questions for half the countries it served
- Founders manually emailed a screenshot of investor balances every Friday. Sometimes Sunday
- Wire transfers came in with mystery references; reconciling them took half a day per week
- KYC documents lived in someone's Drive folder, sorted by whoever uploaded last
- The marketing site was a Webflow template, which read like a Webflow template
- Anyone outside the EU effectively couldn't invest. Currency conversion was on them
- The team had no idea where in the funnel investors dropped off
- A guided KYC flow that asks region-specific questions and saves progress if the investor steps away mid-form
- Investors open a dashboard and see their position, returns, and last activity. Refreshed without a reload
- Stripe handles every deposit in the investor's own currency; reconciliation is automatic and the founders haven't touched a wire reference since
- All compliance documents encrypted, versioned, and tied to the investor record with an audit log
- A marketing site we wrote from scratch around the trust signals financial users actually respond to
- Investors in 14 countries can fund their position without leaving the platform
- Funnel events instrumented end-to-end. The team knows exactly which step is leaking and why
Technology stack.
The tools behind the build, and the reasoning behind each choice.
Marketing pages on the edge, dashboard behind auth. One framework, two very different performance budgets.
Money math and webhook payloads are both type-checked. We have not had a single "wrong currency" bug in production.
A type system the client cannot break by accident. Trust-first design needs consistency more than it needs flair.
Investors check out in their own currency. Reconciliation that used to take half a Friday now happens in a background webhook.
Stripe is the only thing that writes to the ledger. The dashboard reads from it. Disagreements are impossible by construction.
Server cache invalidates on the events that actually matter. Deposit, position change, payout. Investors never see stale data.
Backed by an append-only event log so the investor's view is just a projection. We can replay history if anything ever looks off.
Investors arriving from Google get a sub-second TTFB anywhere in the world. Trust starts before the page even loads.
