Own ISP Block Score API.

What you'd own.

Every artifact below transfers to your accounts on day one. The whole engine.

• ●Scoring algorithm trained on streaming platform and anti-bot vendor detection patterns
• ●Pre-built landing page and copywriting targeting proxy provider CTOs
• ●Cold email outreach template and 500-contact Crunchbase prospect list
• ●Tiered pricing model spanning 10K to 1M IP/day volumes
• ●Free tier trial conversion playbook and onboarding sequence
• ●Financial model and unit economics for $36K to $600K Year 1 ARR
• ●SaaS business playbook: GTM positioning, customer acquisition channels, retention strategy

What Roll Digital builds for you.

Custom scope to take ISP Block Score API from MVP shell to operating business.

• ▸FastAPI backend with async scoring engine, Postgres data layer, Redis caching
• ▸Scoring data pipeline: daily ingest of Cloudflare, DataDome, streaming platform intelligence
• ▸API authentication with rate limiting, tiered access control, usage metering per tier
• ▸Stripe billing integration for $150-$500/mo tiers with usage-based overages
• ▸Dashboard for customers to monitor score accuracy, API health, audit logs
• ▸Alerting system for algorithm accuracy degradation, triggering data refresh workflows
• ▸Email-based customer onboarding automation, 30-day success email sequence

Why this could work.

Proxy providers face immediate, recurring problems: blocked IPs destroy conversion rates. Your cold email GTM targets a tight audience of 500 technical CTOs who understand the pain. Free trial lowers friction. Tiers scale naturally with provider size. $150-500/mo is predictable recurring revenue that sticks if accuracy stays current. Market size is capped but defensible for a bootstrapped operator.

What you'd risk.

Detection accuracy deteriorates weekly as Cloudflare and DataDome release new defenses. Your target customers are adversarial engineers who reverse-engineer scoring signals from API logs within a month, then cancel. Larger proxy platforms build this internally using open-source blacklists. TAM is genuinely small: maybe 800 buyers exist. Churn will be high unless you commit to a costly weekly data refresh cycle that erodes unit economics.

Who this fits.

A technical founder or small SaaS operator with API backend experience and familiarity with proxy, ad-tech, or anti-fraud spaces. Must be able to code FastAPI or hire a backend engineer immediately. Success demands both engineering chops and willingness to cold-email hundreds of CTOs per month. Best fit: solo operator or two-person founder team with some industry connections.

Timeline.

From contract signing to operating business.

1. Day 1
   Technical audit, data source identification, API spec drafted
2. Week 1
   Scoring engine MVP built, Postgres schema deployed, Redis cache live
3. Week 3
   Stripe billing integrated, three pricing tiers active, dashboard prototype
4. Week 6
   API public, landing page live, first 50 cold outreach emails sent
5. Day 90
   10-15 trial signups, 2-3 customers onboarded, score accuracy validated
