The allocation of a ticket in a startup does not fall under the same analytical framework as a listed investment. The risk-return relationship is asymmetrical by nature: the total loss of capital constitutes the modal scenario, while portfolio performance relies on a small number of lines that massively outperform. Structuring your exposure correctly from the start conditions everything else.
Secondary market and liquidity of startup shares in France
The main historical barrier to investing in startups was the almost total lack of liquidity. Before an exit (buyout or IPO), a business angel remained locked in for several years without the possibility of selling their shares to a third party under reasonable conditions.

This lock is beginning to break. Since 2023, platforms like Caption Market and Euronext Private have structured a secondary market for unlisted shares in France and Europe. In practice, an investor can now offer their shares for sale before a classic liquidity event occurs.
We recommend incorporating this data into any entry strategy: the possibility of partial exit changes the calculation of the investment horizon. An investor accessing an active secondary market is no longer forced to provision the entire ticket over a seven to ten-year horizon. Specialized resources, accessible for example on takethecapital.net, help better map the financing and exit mechanisms available.

However, secondary liquidity remains partial. The volumes traded depend on the maturity of the startup and the size of the initial round. For pre-seed or seed tickets, market depth remains low. It is better to consider this option as a safety net rather than a systematic exit strategy.
SPV and club deals: structuring a ticket via syndication
Investing directly in a startup requires having a sufficient ticket to access the round table, often several tens of thousands of euros in seed. Syndication via SPV (Special Purpose Vehicle) changes the game for individual investors.
Platforms like Angelsquare, Sowefund, or syndicates on AngelList Europe pool the tickets of several investors into a single vehicle. The SPV then becomes the shareholder in the startup’s capital, simplifying the capitalization table for the founder and granting access to the deal for profiles that would not have been able to enter alone.
Since 2023-2024, the majority of retail deals now go through these collective arrangements. We observe that this trend is accompanied by a professionalization of sourcing: the lead investor of the SPV conducts due diligence, negotiates terms, and ensures post-investment follow-up. The passive investor benefits from an additional filter, in exchange for management fees (carried interest and management fees).
Points of vigilance on SPVs
- Check the transparency of reporting: a serious SPV communicates at least once a quarter on the valuation and milestones achieved by the startup.
- Analyze the exit conditions of the vehicle. Some SPVs impose a lock-up that prevents any transfer of shares of the vehicle itself, even if a secondary market exists for the underlying startup shares.
- Evaluate the track record of the lead investor. Their deal history, follow-up rate in subsequent rounds, and ability to co-invest with recognized funds are reliable indicators.
Startup due diligence: weak signals to analyze before investing
Public guides emphasize the team and the addressable market. These criteria are necessary but not sufficient. We recommend digging into three often-overlooked dimensions.
Consistency between burn rate and runway
A founder who announces an eighteen-month runway but displays a monthly burn rate incompatible with the declared cash flow sends an alert signal. Always request the projected cash flow table, not just the pitch deck. The consistency between the recruitment plan, marketing expenses, and available cash reveals management rigor.
Dilution clause and shareholder agreement
The shareholder agreement conditions the real value of your participation. Pay particular attention to ratchet clauses (anti-dilution adjustment), drag-along clauses (forced sale obligation), and liquidation preference. A “participating preferred” liquidation preference can absorb the entire proceeds of a sale before ordinary shareholders receive anything.
Traction versus vanity metrics
The number of downloads or unique visitors says nothing about economic viability. The metrics that matter depend on the model: customer acquisition cost relative to lifetime value for a SaaS, thirty-day retention rate for a marketplace, unit gross margin for an e-commerce model. If the founder highlights volume indicators without relating them to an economic ratio, the displayed traction is likely hollow.
IR-PME taxation and tax reduction caps
The IR-PME scheme allows a fraction of the amount invested in an eligible SME to be deducted from income tax. The reduction rate can reach half of the subscribed amount in certain configurations, significantly improving the net risk-return profile of a startup ticket.
This tax lever should not drive the investment decision. A tax advantage never compensates for a bad deal. We regularly observe investors entering mediocre rounds to capture the reduction, only to suffer a capital loss far exceeding the tax savings realized.
- The overall cap on tax niches limits the real advantage. Check that your available reduction envelope is not already saturated by other schemes.
- The maintenance of the tax advantage is conditioned on a minimum holding period. An early sale, including via the secondary market, can trigger a reimbursement of the perceived advantage.
- The startup’s eligibility for the scheme must be confirmed by the company itself (tax certificate). Do not assume that a non-listed company is automatically eligible.
Building a startup portfolio relies on the repetition of calibrated tickets, rigorous sourcing, and a clear management of the exit horizon. The syndication and secondary liquidity tools available since 2023 facilitate access but do not exempt from a thorough analysis of each file. The best investment remains one that you understand well enough to explain your thesis in three sentences.
