Welcome back Data Under Glass, your weekly strategic intelligence extracted from real battlefield deployments, packaged for leaders who need to win, not just understand.
Over the past 8 years, I've rebuilt compensation structures for my startup and other startups hemorrhaging key talent. The pattern is unmistakable: 31% annual attrition in Lagos tech isn't a market reality you accept, it's an execution tax that caps your growth ceiling before you hit product-market fit.
Most founders budget replacement costs at 1x salary. The true number? $180,000+ per senior engineer. That's what walks out the door when you lose institutional knowledge, burn 6 months on recruitment, and train someone who leaves in 18 months with skills you paid for.
Today, you're getting the Retention Economics Playbook—why every cash-heavy compensation structure is doomed, how equity creates the four-year economic tether you actually need, and the operator story that cut churn from 45% to 18%, saving $2.1M in year one.

From The Operator's Desk
Case In Point: Cross-border fintech (Series A, venture-backed) scaling payments infrastructure
Problem: Lost 7 senior engineers in 9 months. Annualized attrition: 45%. At $180K per replacement, that's $1.26M in uncontrolled bleed.
Diagnosis:
Comp model: Cash-heavy, above-market base (80th percentile), guaranteed retention bonuses
Zero meaningful equity (token <0.05% grants perceived as insulting)
No vesting structure = no economic commitment device
Competing against remote offers at $3K-$7K USD monthly (3x local comp)
Intervention:
Eliminated short-term retention bonuses. Adjusted base from 80th to 65th percentile (still competitive). Freed 15% of comp budget to fund equity pool at 12% of fully diluted cap table. Allocated meaningful grants: 0.15% to 0.4% for senior engineers, 0.08% to 0.12% for mid-level.
Structure: 4-year vest, 1-year cliff, quarterly release. Documented option agreements with clear strike prices and exit scenarios. Monthly all-hands showing valuation trajectory and equity value projections.
Outcome:
Churn dropped 45% → 18% (60% reduction). Saved $2.1M in replacement costs year one. Zero senior departures in 18 months post-implementation.
The insight: Grant size mattered less than vesting expectation. Senior talent traded $5K USD monthly offers for 0.25% of a company they believed would hit $200M+ valuation. When employees calculate net worth in "shares owned" rather than "salary earned," you've built the economic tether that survives competitive poaching.
The $180K Replacement Reality
Median compensation for Senior Software Engineer in Nigeria: $22,636 USD annually. True replacement cost: $180,000+ (8x median salary).
Direct Recruitment: $15,000: Search fees, interview cycles consuming 40+ management hours, technical assessments.
Onboarding & Training: $25,000: Three months of reduced productivity, 250+ hours of senior engineer mentoring time at fully loaded cost.
