SonOf

SonOf is an agentic engineering service that transforms your stagnant backlog into shipped production code—paying only when features actually deploy to production. Built by Fulcrum, a studio with 8 years and 100+ products shipped, SonOf combines AI-powered development with senior engineer oversight to eliminate the 70% of backlog items that never get completed.

Product Highlights

• Zero-Risk Pricing Model: Pay exclusively for shipped code with no retainers, setup fees, or lock-in contracts—if it doesn't deploy to production, you don't pay
• 24-Hour Agentic Audit: Proprietary AI system reads your entire codebase, tickets, documentation, and team communications to generate a comprehensive readiness report with security findings, tech debt analysis, and architecture assessment
• Human-Gated Quality Control: Every ticket passes through a senior tech lead for review and story point assignment before development begins, ensuring production-grade code without AI slop
• Full-Stack Integration: Seamlessly connects with GitHub, Jira, Linear, ClickUp, Notion, Slack, Figma, Miro, and Fireflies to ingest complete context in minutes rather than months
• Flexible Engagement Options: Choose pay-as-you-go at $100 per story point or commit to monthly tiers (50-200 SP) with discounts up to 30%—roughly equivalent to 1-8 in-house engineers without the hiring overhead

Use Cases

• Founder-Led Companies: Replace an entire engineering function without hiring a CTO or giving up equity—SonOf audits your product, manages the backlog, ships approved tickets, and reviews every line of code while you maintain full control
• Mid-Stage Startups with Hiring Constraints: Add 1-8 engineer equivalents of throughput without restructuring your organization or navigating months of recruiting; integrates alongside existing teams as additional capacity
• Teams Inheriting Legacy Codebases: Onboard to complex, undocumented, or "unreadable" code in 24 hours instead of 2-4 weeks—the proprietary audit handles projects of any size or messiness level
• Post-Agency/Freelancer Transition: Take over products built by external developers who have disappeared, leaving you with running code you cannot maintain or extend

Target Audience

SonOf serves non-technical founders who need a complete engineering replacement, technical teams of 10-20 people seeking backlog relief without headcount expansion, and any product with proven traction that has more code than current capacity can ship. The service specifically targets organizations that have outgrown vibe-coding prototypes and need production-grade results without traditional agency retainers or freelance hourly rates.
