Case Study: Founders' Agreement (90/10) for a Global Tech Platform Start-Up
This case study analyses an interim founders' agreement for a global tech platform start-up, focusing on how equity, control, incentives, and downside protection are structured at an early stage.
The agreement is designed to balance:
asymmetric founder contribution at inception
future commitment uncertainty
protection against early departure
long-term IP consolidation within the company
It combines vesting, dynamic equity adjustment, and strong leaver mechanics to manage risk while preserving upside alignment.
Gap Analysis (Pre-Agreement Risk)
Before this agreement, the structure would likely create material founder misalignment and downside exposure, particularly given the unequal contribution levels and initial 90:10 ownership. Care was needed to manage allocation of equity to a part-time or uncertain contributor, with no mechanism to adjust ownership if commitment never materialises. This creates a classic early-stage failure mode where one founder carries execution while the other retains disproportionate upside, leading to resentment, stalled decision-making, and difficulty raising capital due to an “unclean” cap table. There would also be no protection against early departure, meaning a founder could leave with meaningful equity despite limited contribution, creating long-term dead equity and governance friction.
Additionally, without formalised vesting, IP assignment, and leaver provisions, the business would face serious structural and investor risks. Intellectual property might remain fragmented or personally owned, undermining acquisition or fundraising readiness. There would be no clear mechanism to reclaim equity or enforce accountability, exposing the company to free-rider problems and potential disputes. Governance would also be weak, with no defined control rights, casting vote, or reserved matters framework—making deadlock highly likely. Overall, the pre-agreement state would be high-risk, informal, and misaligned with venture-scale expectations.
Resulting Structure (Post-Agreement Outcome)
Post-agreement, the structure introduces tight alignment between ownership, contribution, and control, significantly reducing early-stage founder risk. Equity is no longer static—it becomes conditional, time-based, and performance-linked, particularly through vesting and the full-time trigger. This ensures that the minority founder’s ownership scales only if commitment increases, while the majority founder is protected from premature dilution. The inclusion of early exit economics (75/25 override) further reinforces this logic by aligning payout with actual contribution during the most fragile phase of the company. As a result, the cap table remains clean, defensible, and investor-ready.
The agreement also creates a robust institutional foundation for scaling, consolidating all IP within the company and introducing clear governance, control, and dispute mechanisms. Strong leaver provisions eliminate dead equity risk and enforce accountability, while operational and reporting structures ensure ongoing engagement. Control is clearly centralised (via majority ownership and casting vote), avoiding early deadlock while still preserving minority participation. Overall, the post-agreement structure transforms the business into a controlled, scalable, and investment-grade entity, with clear incentives, protections, and long-term value capture mechanisms in place.
Case Study: Dynamic Founder Equity & Control Structure
1. Strategic Objective
The agreement is designed to:
formalise an imbalanced starting contribution (one original founder, one supporting founder)
create a pathway for future equity rebalancing based on commitment
protect the business from early-stage founder drop-off risk
ensure all value (especially IP) accrues to the company
Interpretation:
This structure treats one founder as the core operator, and the other as a conditional long-term partner whose ownership scales with commitment.
2. Commercial Model
1. Initial equity split
Founder A: ~90%
Founder B: ~10%
Implication:
Reflects pre-existing work, risk, and control
Establishes clear decision-making hierarchy from day one
2. Vesting structure
50% vests immediately
50% vests monthly over 4 years
Implication:
Rewards past work
Enforces long-term retention and contribution
Standard startup vesting, but with high upfront recognition
3. Conditional equity uplift (key feature)
If Founder B goes full-time:
Within ~6 months → increases to ~33%
Within ~12 months → increases to ~25%
Implication:
Equity is earned through commitment, not promised upfront
Creates a time-based incentive to join early
Protects majority founder from premature dilution
4. Early exit economics
If company sells within ~12 months:
~75% proceeds to Founder A
~25% to Founder B
All shares accelerate to full vesting
Implication:
Overrides cap table to reflect true contribution at early stage
Prevents windfall gains from short-term passive involvement
3. Operational Engine / Deliverables
Founder roles
Founder A: Managing Director (full operational control)
Founder B: Advisor (initially part-time)
Key operational expectations
Monthly reporting and updates
Regular strategy meetings (bi-monthly + quarterly deep dives)
Shared responsibility for growth and operations
Infrastructure
Accounting outsourced early
Compliance, insurance, and legal handled proactively
Interpretation:
Founder A = execution engine
Founder B = strategic support with optional escalation to operator
4. Ownership / Rights Structure
IP ownership
All business-related IP assigned to the company
Applies to:
pre-incorporation work
ongoing developments
Founder personal brand/IP excluded but:
licensed to company (revocable, ~180 days notice)
Key commercial point:
The company owns all scalable value (IP, product, systems)
Implication:
Enables:
future fundraising
clean acquisitions
cross-market expansion (e.g. UAE subsidiary)
Equity mechanics
Only vested shares carry voting rights
Unvested shares are at risk on exit
5. Exclusivity / Restrictions
Non-solicitation
~6 months post-exit restriction on clients
Non-poaching
~12 months restriction on team/suppliers
Business activity
Founders can pursue other ventures
Must avoid conflicts with company
Commercial purpose:
Protects:
early customer base
team stability
operational continuity
6. Governance / Control
Voting control
Voting aligned with shareholding
Founder A has casting vote during early phase
Board structure
Both founders can be directors
Founder A acts as chairman
Reserved matters
Key decisions require ~75% shareholder approval, including:
major transactions (~£20k+)
fundraising / dilution
structural changes
Interpretation:
Founder A retains effective control
Minority founder has limited blocking power
7. Risk Protection
Leaver framework (highly structured)
Three categories:
Good Leaver → fair value
Bad Leaver → discounted (~10–20%)
Horrible Leaver → nominal value
Unvested shares
Always forfeited on exit
Transferred at nominal value
Additional protections
IP assignment warranties
confidentiality obligations
misconduct and reputation clauses
Implication:
Strong deterrent against:
early departure
underperformance
misconduct
8. Termination Structure
Exit triggers
Voluntary departure
breach / misconduct
incapacity
mutual agreement
Share sale mechanics
Shares first offered to remaining founder
Company can buy if founder declines
Payment can be staged (~180 days)
Dispute resolution
Structured escalation:
internal discussion
independent third party
mediation (CEDR)
courts (UK)
Commercial implication:
Ensures orderly founder exit without destabilising the company
9. Strategic Takeaway
The deal combines:
heavily asymmetric initial ownership
performance-based equity scaling
strict vesting and clawback protections
Founder B’s upside is:
earned through commitment
time-sensitive (early join incentive)
Founder A retains:
control
downside protection
economic priority in early exit
IP structure ensures:
all long-term value sits at company level
Result:
This is a founder-first control structure with conditional partnership upside, turning the second founder into a probationary co-founder whose equity scales with execution and commitment.
