About Second Brain

One workspace for everything freelancers need. No more juggling five apps to run your business.

The Problem We're Solving

Freelancers and small business owners are stuck with a painful trade-off: use a patchwork of tools (Notion for docs, Trello for tasks, FreshBooks for invoices, a spreadsheet for finances) — or pay for expensive enterprise software designed for companies 100x their size.

The first option means scattered data, constant context-switching, and a monthly bill that adds up fast. The second means drowning in features you'll never use, fighting software that wasn't built for how you work.

Neither option is good. We built Second Brain because freelancers deserve better.

Free Business Tools

    Designers, developers, writers, consultants — anyone running a one-person business who needs professional tools without enterprise complexity.

  • 2

    Small Business Owners

    Agencies, studios, and small teams who want a unified workspace instead of paying for 5 separate SaaS subscriptions.

    New Entrepreneurs

    People just starting their freelance journey who need professional tools from day one — without a budget for premium subscriptions.

Our Principles

Simplicity over features

We don't add features for the sake of a longer feature list. Every feature solves a real problem for real freelancers.

One app, not fifty

Context-switching between tools kills productivity. We build everything you need into one workspace so your data and workflow stay connected.

Fair, transparent pricing

Everything is free during beta. When we introduce paid plans, pricing will be simple, public, and fair. No hidden fees, no surprise charges, no dark patterns.

Your data is yours

We don't sell your data. We don't show ads. Your invoices and documents can be exported anytime. We earn your trust by building a product worth paying for, not by locking you in.

Where We're Headed

We're in beta, and we ship improvements every week. Upcoming features include recurring invoices, time tracking, online payment collection, and more. Check our changelog to see what we've shipped recently.

Our goal is simple: become the only tool a freelancer needs to run their business. Not by adding everything, but by doing the essential things better than anyone else.
