Deals & Cases[VC/Startup] Advising a Data-Driven Technology Startup on a Shareholders’ Agreement to Secure Founder Retention and Governance Stability

SOMA Law Group advised a data-driven technology startup on the structuring and drafting of a shareholders’ agreement aimed at reinforcing founder alignment and securing long-term governance stability.

The engagement arose from a clear commercial risk. For an early-stage company whose value is closely tied to a small group of founders, the loss of key individuals - or their transition to competing ventures - can fundamentally undermine the business. The client therefore sought a shareholders’ agreement that would do more than document ownership: it needed to bind the founders into a durable, enforceable framework supporting the company’s continued growth and future investment plans.

In technology- and data-centric startups, human capital is often the most critical asset. Yet general corporate law offers limited protection against founder exits, opportunistic share disposals, or competitive spin-outs. Against this backdrop, the client recognised the need to hard-wire commitment, continuity and alignment into its internal equity structure at an early stage.


SOMA designed a shareholders’ agreement calibrated to these priorities.

  • Non-compete obligations were drafted with particular care, extending beyond generic industry restrictions to define prohibited activities by reference to the company’s actual business model, with clearly articulated temporal and geographic scope. This approach was intended to meaningfully reduce the risk of technology leakage and rival ventures.

  • Ongoing service obligations required principal shareholders to remain actively involved in the business for a defined period. Breach or early departure triggered compulsory transfer of shares - at par value or another agreed benchmark - to the company or remaining shareholders, creating a strong disincentive to premature exits.

  • Transfer restrictions (lock-ups) were introduced to preserve stability in the company’s ownership and control, complemented by carefully balanced rights of first refusal and tag-along rights to manage future liquidity events and mitigate shareholder disputes.

  • To ensure that these provisions operated in practice rather than in name only, key obligations were supported by meaningful contractual penalties, strengthening enforceability and deterrence.


The resulting framework established a clear alignment of interests among the founding shareholders, while also providing external investors with comfort around governance discipline and founder retention.

For startups, a shareholders’ agreement is not simply a record of share ownership. When structured effectively, it is a strategic tool for protecting core talent and laying the foundations for sustainable, long-term growth.
