1. The Challenge: Fast Capital Without Valuation

Early-stage startups face a fundamental dilemma. The product is still in development, the market remains uncertain, and revenue is non-existent. Meanwhile, the bank account is draining, especially for bootstrapped companies.

A classic equity round would bring clarity, but it also demands significant time and resources:

a well-founded company valuation (pre-money valuation);
negotiations covering vesting, governance, and shareholder rights; and
term sheets, due diligence, and legal advice.

Early-stage startups simply don't have these resources, or would be better off investing them in product development and market entry.

CLAs circumvent this problem. As a debt instrument, they are legally streamlined, faster to execute, and push the valuation question into the future. But this postponement is not a solution; it's merely a delay. And it can become expensive.

2. What is a CLA? Definition and Functionality

Legally, a CLA is a loan that converts into equity upon the occurrence of specified trigger events:

(Qualified) financing round
Exit or M&A transaction
Initial Public Offering (IPO)
End of term (Maturity Date)

Conversion occurs at the request of either the startup (borrower) or the CLA investor (lender). In practice, CLAs typically convert automatically at the next equity round.

Economically, CLAs differ fundamentally from traditional loans. The conditions under which investors later become shareholders are already set at closing:

Valuation Cap: Maximum valuation at which the CLA converts
Discount Rate: Discount applied to the next round's valuation (typically 15–25%)
Interest: Accrued interest that increases the conversion amount
Conversion Price: Price at which CLA investors receive shares

These parameters act like a hidden valuation with profound implications for founder dilution.

3. Why Convertible Loan Agreements Are So Attractive

From a founder's perspective, CLAs primarily offer speed:

No valuation debates
No shareholder agreements
No governance negotiations
Lower transaction costs
Rapid execution (days to weeks instead of months of negotiation)

Especially in the pre-seed phase, when vision is more important than hard KPIs, CLAs save time and hassle.

From an investor's perspective, the appeal lies in the protection:

Entry at favorable terms (via discount and cap)
Downside protection (loan repayment remains possible)
No immediate shareholder commitments
Optionality: conversion becomes attractive only upon success

This alignment of interests is legitimate. But it also means CLAs are rarely economically neutral. In most cases, CLA investors benefit disproportionately at the expense of founders.

4. The Economic Levers: Where CLAs Become Expensive

The true costs of a CLA only become apparent in the next financing round. Four parameters are critical:

Valuation Cap: The Hidden Ceiling

The valuation cap determines the maximum valuation at which the CLA converts, regardless of the actual valuation achieved in the subsequent financing round.

Example:

CLA of EUR 200,000 with a pre-money valuation cap of EUR 3 Mio.
Series A raises at a EUR 6 Mio. pre-money valuation
CLA converts at EUR 3 Mio. (not EUR 6 Mio.)
CLA investor receives twice as many shares for their CLA amount as a Series A investor investing the same amount

The problem:

An overly low valuation cap locks in a cheap entry price, even if the startup has since achieved substantial growth.

Discount Rate: An Additional Markdown

The discount rate grants CLA investors a discount on the next round’s valuation. Standard discounts range from 15-25%.

Example:

Series A with EUR 5 Mio. pre-money valuation
CLA with 20% discount
CLA converts at EUR 4 Mio. (20% cheaper)

Combination with valuation cap: Many CLAs include both a cap and a discount. The investor selects whichever option is more favorable (usually the cap).

Interest: The Underestimated Multiplier

CLAs accrue interest, typically at 5–8% per annum. This interest isn't paid out but increases the conversion amount.

Example:

CLA of EUR 100,000.00
Interest: 8% p.a.
Term: 2 years (until Series A)
Conversion amount: EUR 116,640.00

With multiple CLAs and extended terms, interest can accumulate substantially.

Term and Conversion Mechanisms

CLAs typically have a 12–36 month term but what happens if no financing round materializes?

Repayment: The startup must repay the loan (often impossible during a crisis)
Extension: Renegotiation under (usually worse) new terms
Forced conversion at investor-friendly emergency valuation term

Additionally, conversion mechanisms may allow investors to delay conversion or attach conditions.

Cap Table Opacity

Many startups sign multiple CLAs with varying terms, creating:

An unclear cap table
Unpredictable dilution
Conflicts between CLA investors and subsequent equity investors
Complicated Series A negotiations

Series A investors typically require full conversion of all outstanding CLAs. The cumulative dilution often catches founders off guard.

5. Equity Financing as an Alternative: When an Equity Round Makes More Sense

Classic equity financing is more elaborate but it also delivers clarity:

Transparent valuation: Everyone knows what the company is worth
Clear dilution: Founders know exactly what they are giving up
Defined shareholder rights: Governance, veto rights, and participation are fromatlized
Clean cap table: No hidden conversion claims

This transparency is especially valuable heading into Series A. Series A investors prefer clear structures. A messy CLA stack can complicate negotiations or even cause them to fail.

The supposed advantage of CLAs therefore lies less in superior economics, but in but in deferring difficult decisions. Deferral, however, doesn't solve problems, it merely postpones them

6. When Is a Convertible Loan Agreement Appropriate?

CLAs can be an effective tool—under the right circumstances:

True bridge financing: The next equity round is already in concrete planning (6–12 months out)
Limited Volume: CLA volume is managable (max. 10–20% of anticipated Series A)
Consolidated investor base: Few CLA investors with standardized terms
Fair terms: Realistic valuation caps (2–3× current valuation), moderate discounts (15–20%)
Strategic investors: Business Angels or corporates bringing real added value beyond capital

CLAs become problematic when:

They substitute for structured financing
Multiple CLAs with divergent caps and discounts accumulate
The next equity round is still distant or uncertain
The valuation cap is unrealistically low
CLAs roll forward across multiple financing rounds

In these scenarios, risks compound. The consequence: unexpected dilution, weak negotiating position in Series A, and conflicts within the investor base.

7. CLAs Are Not Fast Money, but Deferred Fundraising

Convertible Loan Agreements are a useful instrument, not a panacea. Founders entering into a CLA are making economic decisions with long-term consequences even if those consequences aren't immediately visible.

CLAs shouldn't be treated as standard boilerplate, but as serious negotiation topics. The critical questions are:

Is the valuation cap realistic and fair?
What is the total dilution from CLA plus next equity round?
Which conversion triggers are defined, and what happens if they don't occur?
How will the CLA impact Series A negotiations?

Early legal and strategic structuring pays off, at the latest when the loan actually converts into equity.

FAQs

What's the difference between a CLA, SAFE, and Convertible Note? CLAs (Germany) and Convertible Notes (USA) are interest-bearing loans. SAFEs (Simple Agreements for Future Equity) are not loans but pure conversion rights without interest or repayment obligations. In Germany, CLAs are the market standard.

When does a CLA convert into equity? Typical triggers: qualified financing round, exit, M&A, IPO, or maturity. Conversion usually occurs automatically.

What is a valuation cap? The maximum company valuation at which the CLA converts, even if the actual valuation in the subsequent financing round is higher. A low cap increases founder dilution.

How much dilution is caused by CLAs? It depends on the discount (15–25%), valuation cap, and accrued interest. With a 20% discount and low cap, dilution can significantly be significantly higher than for Series A investors.

Are CLAs common in Germany? Yes, especially in pre-seed and seed. From Series A onwards, classic equity rounds with transparent valuations and shareholder agreements dominate.

What happens if no follow-on financing materializes? The startup must either repay the loan (often impossible), convert at investor-friendly emergency terms, or face insolvency.
