Pre-Seed to Series A — What to Build at Each Stage
| Stage | Funding Range | What to Build | What NOT to Build | ClickMasters Recommendation |
|---|---|---|---|---|
| Pre-seed / Bootstrapped | £0–£250K | Landing page + waitlist, proof of concept, design prototype | Full production application | Validate demand before any code — use Typeform/Webflow first |
| Pre-seed / Friends & Family | £50K–£500K | MVP (core loop only, 3–5 features) | Admin portal, billing, advanced analytics | ClickMasters MVP: £12K–£45K fixed price |
| Seed | £500K–£3M | Product-market fit iteration, 8–12 features, basic billing | Microservices, admin portal v2, mobile app (unless core) | Continue MVP iteration — do not rebuild yet |
| Series A | £3M–£15M | Scale the product — performance, reliability, new features | Full rewrite (unless truly necessary) | Staff augmentation to scale your team — not another agency |
| Series B+ | £15M+ | Hire in-house engineering team | Remain dependent on agency | Transition to in-house — agency for specific skills gaps |
