# Growth Hack

The SCF Growth Hack program is an 8-week, competition-style GTM/PMF program for Stellar mainnet projects happening on a quarterly basis. Each cohort funds 10–15 teams with **$20K (in XLM\*)** to run a **4-week acquisition + 4-week retention** campaign; top performers share **up to $200K (in XLM\*)** in performance awards. The program bridges SCF Build to eligibility for additional marketing support (including SDF Marketing Grants and SDFMatching Fund).

\**To determine the number of XLM equal to the USD value of any Award, the USD valuation of XLM shall be calculated using the CF Stellar Lumens-Dollar Settlement Price as administered, maintained, and reported by the cryptocurrency index provider CF Benchmarks Ltd. (using the ticker “XLMUSD\_RR”) (available at <https://www.cfbenchmarks.com/indices/XLMUSD\\_RR>), or, if such settlement price is unavailable or reasonably suspected by SDF to be unreliable, the settlement price as reported on a substantially similar and equally reputable cryptocurrency index provider as determined by the SDF in its discretion. The USD valuation of XLM for any particular Award shall be calculated using the CF Stellar Lumens-Dollar Settlement Price (or other agreed upon settlement price) reported on the day such Award is paid. The Participants acknowledge and understand that XLM is a highly risky and volatile asset, and that SDF does not provide any representations, warranties, or guarantees of its value.*<br>
