CTO Advisory Playbook: MVP to Production in 90 Days
Speed without discipline is rework. This playbook compresses discovery, delivery, and readiness into a 90-day operating cadence that boards respect and engineers enjoy. It leans on Vercel deployment and hosting services for frontends, a cloud-native core for APIs, and a Swift and Kotlin development team for mobile parity, all under a Full-cycle product engineering model where the team owns outcomes, not tickets.
Days 0-14: Strategy, guardrails, and the "one metric"
- Define a One Metric That Matters tied to revenue or retention; e.g., "qualified activations per account within 7 days."
- Decide rails: budget, compliance scope (SOC 2 Type I), data boundaries, supported regions, and SLOs (p95 latency, uptime).
- Architecture decisions: edge-rendered web on Next.js with Vercel deployment and hosting services; managed Postgres; an event bus; and opinionated CI from day one.
- Write the "anti-roadmap": what you will not build before launch. Ruthless focus keeps 90 days realistic.
Days 15-30: Thin-slice MVP with production bones
Ship a vertical slice that proves value, not a demo. Build the smallest workflow that earns willingness to pay, while laying foundations you will not rip out later.
- Web: Next.js app with edge functions for auth, image optimization, and preview deployments on every pull request.
- API: a single bounded context, versioned REST or GraphQL, with contract tests and rate limits from the start.
- Mobile: staff a Swift and Kotlin development team only if mobile is a growth unlock; otherwise ship responsive web plus native wrappers for push and deep links.
- Data: one canonical user table, one analytics stream; resist ad hoc stores.
Days 31-45: CI/CD, environments, and quality gates
- Pipeline: trunk-based development, required code owners, and ephemeral test environments. Each commit gets an automated security, lint, and unit test gate.
- Environments: dev, staging, production. Staging mirrors production infra, no exceptions.
- Secrets/IaC: everything in code-Terraform, OpenAPI, and schema migrations with rollback plans.
Days 46-60: Hardening, scale, and cost truth
- Load rehearsal: run k6/Gatling to 2× expected launch traffic. Validate p95 and p99, not averages.
- Chaos drills: terminate pods, inject latency, rotate keys. Produce a crisp on-call runbook.
- Cost profiling: measure per-tenant cost at idle and under load. Kill or batch expensive fan-out patterns.
- Security passes: SAST/DAST, dependency audits, and PII classification. Encrypt at rest and in transit, prove it.
Days 61-75: Beta, feedback loops, and pricing signals
- Private beta with 10-20 design partners. Weekly deployment cadence with release notes they can forward internally.
- Instrumentation: task-level analytics, cohort retention, and feature flags tied to entitlement tiers.
- Support: a shared slack channel, <24h response SLO, and a close-the-loop template for PMs.
Days 76-90: Launch readiness and ops handoff
- Game day: simulate a launch with traffic spikes, incident escalation, and rollback practice.
- Compliance: evidence packets for SOC 2 controls; access reviews recorded and automated.
- Commercials: usage meters that drive invoices; self-serve upgrades; clear limits baked in error messages.
- Handoff: who owns what after day 90-on-call rotations, change approval policy, and a simple roadmap for the next 60 days.
Case snapshot: From mockups to paying users
A B2B scheduling startup followed this plan. Web landed on Vercel deployment and hosting services; the backend ran on a managed Postgres plus worker queue. In 82 days they went from Figma to production with 18 pilot accounts. Results: 98.9% week-one retention for trial users, p95 page render at 180ms, and $0.41 marginal cost per active user per month. The trick wasn't heroics; it was picking a single conversion path, instrumenting it mercilessly, and running two performance rehearsals before beta.
Hiring and capacity: get serious, fast
Under Full-cycle product engineering, you hire for ownership. You need a staff-level tech lead, a product-minded designer, two strong full-stack devs, and access to a Swift and Kotlin development team if native is truly critical. If you lack this bench, bring in vetted help. Partners like slashdev.io provide remote engineers and agency expertise that slot into your cadence without ceremony, preserving velocity while you hire permanently.
How Vercel accelerates the 90-day plan
- Preview environments on every pull request make product reviews continuous, not theatrical.
- Edge functions push personalization close to the user, dropping p95s without exotic caching.
- Out-of-the-box CDN, image optimization, and ISR reduce infra toil so the team builds product.
Executive checklist you can copy
- One metric, three SLOs, zero secret spreadsheets.
- Product doc: problem, user, thin slice, anti-roadmap, pricing hypothesis.
- Tech doc: architecture diagram, data model, CI gates, runbook.
- Beta plan: 15 accounts, weekly notes, explicit exit criteria to GA.
