Tech Stack Cost by Company Size: From Seed to Enterprise
What companies should actually be spending at each stage, with specific tool recommendations and the common mistakes to avoid.
Stage Overview
| Stage | Engineers | Monthly Total | Per Engineer/Mo |
|---|---|---|---|
| Seed | 1-5 engineers | $800 - $2,000 | $150 - $400 |
| Series A | 5-20 engineers | $3,000 - $12,000 | $400 - $1,000 |
| Series B | 20-80 engineers | $15,000 - $80,000 | $1,000 - $2,500 |
| Growth | 80-300 engineers | $80,000 - $400,000 | $2,000 - $4,000 |
| Enterprise | 300+ engineers | $400,000 - $2,000,000+ | $3,000 - $8,000 |
Seed (1-5 engineers)
$150 - $400/engineer/moRecommended Tools
Vercel/Railway ($0-$20), GitHub free, Linear free tier, Sentry free tier, basic AWS/GCP ($200-$500), VS Code (free), Slack free
Strategy
Use free tiers aggressively. Do not pay for anything you can get for free at this scale. Your hosting bill should be under $500/month. Your entire SaaS bill should fit on one credit card statement.
Common Mistakes
Over-engineering with Kubernetes or complex microservices. Buying enterprise-tier tools. Spending time evaluating tools instead of building product.
Real-World Example
$20/mo Vercel + $0 GitHub Free + $0 Linear Free + $0 Sentry Free + $300/mo AWS = $320/mo total ($80/engineer/mo for a 4-person team)
Series A (5-20 engineers)
$400 - $1,000/engineer/moRecommended Tools
GitHub Team ($4/user), Linear ($8/user), Sentry Team ($26/user), AWS/GCP ($1,000-$4,000), Datadog Infrastructure ($15/host), Copilot ($10/user), Slack Pro ($8.75/user)
Strategy
Start paying for tools that save engineering time. GitHub Team for code review. A real monitoring solution. A project management tool the whole team uses. But avoid per-seat tools with enterprise pricing.
Common Mistakes
Signing annual contracts too early. Buying tools you do not need yet (APM, CSPM). Hiring a platform engineer before you have a platform to manage.
Real-World Example
12 engineers: $0 GitHub Team + $96/mo Linear + $312/mo Sentry + $1,200/mo AWS + $180/mo Datadog + $120/mo Copilot = $1,908/mo ($159/engineer/mo)
Series B (20-80 engineers)
$1,000 - $2,500/engineer/moRecommended Tools
GitHub Enterprise ($21/user), Datadog APM + Logs ($31+/host), Snyk Team ($52/dev), Copilot Business ($19/user), Slack Business+ ($12.50/user), Notion Business ($10/user), dedicated CI/CD budget
Strategy
This is the stage where costs start compounding. Every per-seat tool now costs 5-10x what it cost at Series A. Invest in a FinOps practice early. Negotiate annual contracts with volume discounts. Consider a SaaS procurement tool.
Common Mistakes
Letting every team choose their own tools without coordination. Not negotiating contracts. Running production on default instance sizes without right-sizing. No cost governance.
Real-World Example
50 engineers: $1,050/mo GitHub Enterprise + $3,100/mo Datadog + $2,600/mo Snyk + $950/mo Copilot + $12,000/mo AWS + $4,500/mo data platform = $24,200/mo ($484/engineer/mo visible, ~$700 with hidden)
Growth (80-300 engineers)
$2,000 - $4,000/engineer/moRecommended Tools
Full enterprise tooling suites, dedicated platform team, FinOps practice, SaaS management platform (Zylo/Productiv), custom internal developer platforms, enterprise security (Wiz, CrowdStrike)
Strategy
At this stage you need dedicated cost management. Hire or assign a FinOps engineer. Implement approval workflows for new tool purchases. Run quarterly vendor audits. Negotiate multi-year enterprise agreements for volume discounts.
Common Mistakes
No centralized tool governance. Shadow IT proliferating. Not renegotiating contracts at scale. Paying per-seat for tools that should be usage-based at this volume.
Real-World Example
150 engineers: $3,150/mo GitHub + $15,000/mo monitoring + $8,000/mo security + $45,000/mo cloud + $18,000/mo data platform + $12,000/mo collab = $101,150/mo ($674/engineer/mo visible)
Enterprise (300+ engineers)
$3,000 - $8,000/engineer/moRecommended Tools
Multi-cloud infrastructure, enterprise license agreements, custom internal platforms, dedicated security operations center, compliance tooling (SOC 2, ISO 27001, HIPAA), vendor management team
Strategy
At enterprise scale, the tool is not the cost; the people managing the tool are the cost. Focus on platform engineering to reduce per-engineer toil. Consolidate wherever possible. Run a formal vendor management program.
Common Mistakes
Tool sprawl (400+ apps with no governance). Not leveraging scale for volume discounts. Over-customizing vendor solutions instead of adapting processes. Running cloud resources without auto-scaling.
Real-World Example
500 engineers: $10,500/mo GitHub + $50,000/mo monitoring + $35,000/mo security + $180,000/mo cloud + $65,000/mo data + $40,000/mo collab = $380,500/mo ($761/engineer/mo visible, ~$1,200 with hidden)
Scaling Inflection Points
At certain team sizes, new tools and practices become necessary. Missing these inflection points creates technical debt that compounds over time.
Dedicated CI/CD pipeline, basic monitoring, structured code review process
APM and distributed tracing, security scanning in CI, on-call rotation tooling
Data platform (warehouse + BI), FinOps practice, SaaS governance, dedicated platform team
Internal developer platform, enterprise security tooling, vendor management, formal change management
SaaS management platform, dedicated FinOps engineer, multi-cloud strategy, compliance automation
