About Leiko

Built because we needed it ourselves

Leiko started from a simple frustration: running a one-person business shouldn't require ten different tools and half your day spent on admin. So we built the assistant we wished existed.

Origin

The problem we kept hitting

As a freelancer and entrepreneur in Finland, the daily reality looks like this: invoicing in one app, tracking receipts in another, managing tasks in a third, checking calendar in a fourth, and manually copying data between all of them. Every month-end is a scramble of screenshots, spreadsheets, and “where did I put that receipt?”

We tried everything. Accounting software that was built for accountants, not entrepreneurs. Project tools designed for teams of fifty. CRM systems that needed a CRM system to manage. None of them talked to each other, and none of them understood that a solo founder's workflow is fundamentally different from a corporate one.

The breaking point came when we realized we were spending more time managing the tools than doing actual work. That's when the idea for Leiko crystallized: what if there was a single intelligent layer that sat on top of everything and just… handled it?

One conversation
What we believe

Principles that shape every decision

01

Conversation over forms

Business tools are built around databases. Leiko is built around a conversation. Tell it what you need. It handles the structure, the fields, the storage. You handle the thinking.

02

Confirm before acting

AI should draft, suggest, and prepare — but never send an invoice, book a meeting, or delete data without your explicit confirmation. You are always in the loop.

03

Your data stays yours

EU data residency. No selling to advertisers. No training third-party models on your data. You can export or delete everything at any time. Privacy isn't a feature — it's a constraint we build around.

04

Proactive, not reactive

A good assistant doesn't wait to be asked. Leiko surfaces what matters — unpaid invoices, upcoming deadlines, unbilled hours — before you have to think about it.

05

Built for one, not many

Most business software assumes a team. Leiko assumes you're alone. No seats to manage, no permissions to configure, no admin panel to learn. Just you and your business.

06

Ship weekly, learn daily

We're in beta and we ship every week. Every user conversation, every frustration, every “why can't it just…” becomes a line item in next week's sprint. Speed beats perfection.

Timeline

How we got here

November 2025
The idea takes shape
First prototype built over a weekend. A chat interface connected to a Supabase database with basic invoice creation. The “aha” moment: creating an invoice in 15 seconds by talking instead of 5 minutes filling forms.
December 2025
Core architecture
Built the AI agent framework with tool calling, intent extraction, and human-in-the-loop confirmation. Chose Expo/React Native for mobile-first. Integrated Anthropic Claude as the primary AI engine.
January 2026
Invoicing, receipts, tasks
Full invoicing pipeline: create, preview PDF, send via email. OCR receipt scanning with Google Cloud Vision. Task management with natural language deadlines and project hierarchy.
February 2026
Integrations and intelligence
Google Calendar two-way sync. Gmail integration with AI summaries. Time tracking with billable hours. AI memory system that learns client details, rates, and routines. Today view with proactive insights.
March 2026
Private beta launch
Opened private beta for early adopters. Iterating rapidly on feedback. Building multi-currency support, CRM features, and the web companion. This is where you come in.
Under the hood

How it's built

Mobile-first (React Native / Expo)

Your business lives in your pocket. Leiko is built natively for mobile, not adapted from a web app. Fast, smooth, always accessible.

Anthropic Claude + Google Gemini

Best-in-class AI for understanding context, executing complex multi-step workflows, and maintaining coherent conversation across sessions.

Supabase (EU region)

PostgreSQL database with row-level security. Your data lives in the EU. Real-time sync. Robust authentication. Open-source infrastructure.

Human-in-the-loop architecture

Every destructive or significant action requires your confirmation. The AI proposes, you approve. Built at the system level, not bolted on.
