Case Study: Founders' Agreement (90/10) for a Global Tech Platform Start-Up

Case Study: Founders' Agreement (90/10) for a Global Tech Platform Start-Up

April 05, 20267 min read

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.
