I'm 15 and built this solo. Freelancers typically juggle 5-6 disconnected tools to run what is essentially a one-person business. Helios puts CRM, contracts, invoices, proposals, time tracking and client outreach in one place. Free tier available, no card required. Pro is £29/mo founding rate. Also built three free tools that don't need an account: rate calculator, invoice template, and proposal template — helios.today/tools Built on React, Node.js, Supabase and Stripe. Currently pre-revenue and would genuinely appreciate brutal feedback.
