If an entrepreneur "adopted" this product today, here's the realistic math.

Fermi summary

If you land 145 teams at $20/mo by month 12, that's $35k ARR - but GitHub Actions is a free 20-line substitute, so you're selling convenience, not capability, and that's a rough sell to engineers.

Market size (TAM)

$4.2M

~210k GitHub-org engineering teams with 5+ devs who actively manage PR workflow; ~5% would pay a dedicated tool at ~$400/yr avg rather than write a free Action script

Year-1 ARR range

$7k - $108k

midpoint $35k

Gross margin

92%

Investment to production

$19k

Dev: $7k for Stripe billing, GitHub App hardening, webhook retry logic, and multi-org support. Marketing: $8k for GitHub Marketplace SEO + o

Probability of success

17%

P(reaching mid case in 12 months)

Expected take-home Y1

$-13551

probability-weighted, after investment

Go-to-market motion

GitHub Marketplace organic listing + cold LinkedIn outreach to VPs of Engineering at 50-500 person startups, targeting teams that already mandate PR size in their eng handbook but enforce it manually.

Key risks

GitHub Actions makes this replicable in 20 lines of YAML for free - senior devs will DIY rather than pay, and juniors follow their lead
GitHub itself is rolling out more native code-review guardrails (merge queues, rulesets) that eat directly into this feature surface
Single-feature moat: if a competitor bundles PR size enforcement into a broader code-review analytics suite at similar price, GitGuard has no defensible wedge
GitHub Marketplace discovery is opaque and dominated by incumbents like PullRequest, Graphite, and LinearB - organic acquisition is slow without a community strategy
