We build Next.js applications with AI features that actually work in production. 15 years of engineering. Obsessed with performance and maintainabilitynumentechnology.co.uk/?utm_source=tw… United KingdomJoined October 2025
Quick way to check if AI makes sense for your product: can you calculate a payback period under 12 months? Support ticket deflection, conversion lift, time saved. If you can't tie it to a number, you're adding complexity without a business case.
Pattern I've noticed:
Agencies that show you beautiful mockups in week 1 tend to disappear by month 6.
Agencies that spend week 1 asking "why?" and "who are your users?" tend to stick around for years.
Flash vs substance.
The ones who take time to understand usually care about outcomes, not just deliverables.

Honest question for founders:
When you're choosing between two developers/agencies with similar pricing, what's the deciding factor?
(I'm curious what actually tips the decision beyond "who quotes lowest")
Your website is slow because of "invisible" code.
Example I found last week:
- Site loads in 9 seconds
- Content is 500KB
- JavaScript bundle is 3.2MB
Translation: User downloads 6x more code than content.
Modern frameworks fix this (code splitting, tree shaking, lazy loading).
Quick check: Open DevTools → Network tab → Refresh
If JS is bigger than your actual content, you have a problem.
What's your biggest fear about hiring a web agency? (Honest answers only - trying to understand what's actually holding people back from pulling the trigger.)
3 signs you DON'T need a custom Next.js site yet:
1) You haven't validated your offer (no sales = don't spend on tech)
2) You're pre-revenue and bootstrapped (Framer/Webflow will do)
3) You have under 1,000 site visitors/month (traffic first, then optimize)
Save the £15K. Use it for ads or hiring. Build custom when speed/scale actually matters.
@llm_san The "trying to socialize??" is too real. I've learned: Something gives. Either you accept that for this season, or you burn out trying to keep all plates spinning. For me it was: Pick 3 max, rotate the 4th monthly. Socializing became "gym with a friend" to double up.
@IAmPascio The hardest part is #1. Most people skip researching the community and jump straight to building. Then wonder why nobody buys. Spending time in the community before selling to it = unfair advantage.
@jonbrosio Spot on. I've seen agencies pitch "custom CMS" when the client's real need was "make changes without a 2-week delay." Same product, different framing. One sells features, the other sells freedom. The result is what they'll pay for.
Pro tip: Before hiring any web agency, ask:
"What happens if I need changes 6 months after launch?"
If they hesitate or say "we can quote you" → RUN.
You're not buying a website. You're choosing a partner who'll either stick around or disappear when you need them most.
