I want to talk about how I built @MCPCore - a cloud platform where developers create, deploy, and manage MCP servers from their browser - and what 10+ years of backend experience taught me about using AI in production work. Not the hype version. The honest one.
Every idea is already taken. So what?
I'm a backend engineer. I've spent most of my career building server-side systems, and I currently lead a backend team at my company. At some point I wanted to build something of my own. A product. Something real.
With AI bots getting harder to detect, there s been growing discussion around platforms using biometric verification (like face scans) to confirm real users.
Cool in theory... Reddit is full of bots, fake accounts and garbage engagement. But let s be real
You shouldn t need to open five dashboards just to change pricing.
Now you don t.
Plug Cursor, Claude Code, VS Code, Gemini, Windsurf or any MCP-compatible client directly into your Flexprice workspace and prompt your billing infrastructure like it s code.
Startup land rewards motion. Announcements, launches, funding headlines, feature drops - it all looks like acceleration.
But visible activity isn t the same as real progress.
Shipping fast doesn t mean you re building the right thing. Raising capital doesn t mean you found product-market fit. Talking about scale doesn t mean you solved anything painful.
A lot of ecosystems reward velocity because it s easy to measure. Markets reward outcomes because they re impossible to fake.
Subscription pricing struggles when value is variable. Pure usage pricing is accurate, but messy to explain, messy to predict, and easy to hate when the bill surprises you.
Credit-based pricing sits in the middle:
Simple for customers: I bought 10,000 credits
Flexible for teams: bundle tokens, GPU time, storage, calls into one unit
Better for finance: prepaid revenue, clearer burn, fewer billing shocks
Better for product: you can experiment with packaging without rebuilding billing every time
The bigger trend is this: We re moving from pricing as a plan to pricing as a runtime.
If I want to remove one company, I remove it everywhere. If I pause outreach, I double-check multiple tools to make sure nothing accidentally goes out.
I've been talking to founders across different stages and ICPs, and here's what's surprising: there's no consensus anymore. 1. Cold email is crushing it for some teams and completely dead for others. 2. LinkedIn DMs are either goldmines or ghost towns. 3. And somehow, cold calls are quietly working for a subset of B2B companies.
It feels like the best practice playbooks don't account for how much this varies by your specific ICP, deal size, and market maturity.
So I'm curious about your experience, not what you think should work, but what's actually generating pipeline for you right now. Is it cold emails? Calls? LinkedIn outreach? Or have you found success with a completely different motion?
Would love to hear what's working in your world. What outbound channel is moving the needle for you?
A lot of people read YC RFS Spring 2026 as a trend list. It s not. It s a signal of where work inside companies is quietly breaking.
Here s how this shows up in real teams:
Product teams YC references @Cursor , but the opportunity isn t coding faster. It s helping PMs synthesize interviews, metrics, and feedback to decide what to build next.
Finance and hedge funds Firms like Renaissance, Bridgewater, and D.E. Shaw won by systematising decisions. AI-native hedge funds push this further with continuous, machine-driven strategies.
As more teams build AI agents, search, and personalized feeds, one problem keeps surfacing. Not generation. Not model quality.
It s retrieval and ranking. Deciding what information should show up and in what order.
Most teams solve this by stitching together systems. Vector search for meaning. Keyword search for precision. Custom logic for business rules. Over time, relevance logic spreads everywhere and becomes hard to change.
