Mission
CLL Global's mission is to abolish chronic lymphocytic leukemia (CLL) as a threat to the life and health of patients by accelerating CLL research.
As stated on its FY2025 Form 990.
Programs
RESEARCH GRANTS: The CLL Global Research Foundation's primary activity is to accelerate research. The need is urgent to accelerate promising, untapped areas of research. CLL Global provides grants through several mechanisms to fund novel, patient-oriented concepts. The intention is to fund the best CLL science in the world. In particular, CLL Global targets monoclonal antibodies, prognostic factors, vaccines & gene therapy, CLL survival pathway, genetics, molecular targets, and drug development. Continued on Schedule O A Scientific Advisory Board (SAB) develops the research priorities and oversees the development and implementation of the submission, evaluation and funding process for grant application cycles. SAB members have extensive experience in treating CLL patients, developing new drugs and other tools, and studying various aspects of the disease. The research grant section also allows support of postdoctoral fellows conducting a CLL-specific project. In 2025, CLL Global awarded new research/individual grants ranging from $100,000-$250,000. Applicants intially submit proposals for grants up to $150,000 in funding for one year. Applicants identify project milestones. Upon…

The members are divided into working groups focusing on one of five big ideas in CLL research (refractory disease, immune dysfunction and restoration, novel therapeutic targets and approaches, Richter's transformation, high risk and genomically complex disease). The Alliance was built to encourage close collaboration between and among working groups. As such, meetings are held annually to bring investigators together to collaborate.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2021 to 2022, from $12M to $11M (−12%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
81% of CLL Global Research Foundation’s revenue is contributions — more donation-reliant than the typical peer (51% for the typical peer).

Who funds it, year by year
2017 → 2023: the base broadened from 7 funders to 13 funders, grant income rose $1.2M → $2.3M.
9 of 25 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 7% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of CLL Global Research Foundation’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
CLL Global Research Foundation leans on a few funders — its largest provides 82% of grant income and the top three 93%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
Largest funder’s share by year: 2017 84% · 2018 78% · 2019 71% · 2020 78% · 2021 82% · 2022 79% · 2023 88% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
63% of CLL Global Research Foundation's funders are still giving 3 years after their first grant; 76% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
CLL Global Research Foundation draws 99% of its grant income from funders outside Texas, across 12 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.0M arriving through sponsors registered in 8 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
