About Us

Our nonprofit clients tell us their biggest challenge is 'building capacity' for fundraising, board development, volunteers, and more. Perhaps you're like our clients? You are not alone.

The Foundation Center studied this issue in 2000, and again in 2010, and came up with some recommendations on how to help nonprofits build their capacity. Things like webinars and seminars and conferences. How many of THOSE have we attended?

And yet a decade later, capacity building is STILL an issue that keeps nonprofits from success.  

What isn’t working?

Our firm, Harvest Development Group, has studied this issue for four years. We have worked with over 1000 prospective clients in trying to establish a solution that met their needs and their budget, helping them gain more control over their operations and success in fundraising, board development and more.

What we have learned is that for each nonprofit, where the process of capacity building fell apart was in execution.

Good ideas, strategy, recommendations, action steps- all of these concepts are excellent in theory but will NOT WORK if you feel unable to execute. Some obstacles to execution are time and resources, confidence and experience, and accountability.


When we realized the scope of this problem, we thought, what if we could create a learning lab, curating the best of educational videos, podcasts, journal articles, and books, in which nonprofit executives could reliably and affordably access these tools in an online workspace, at any time?

And what if we supported each learner with a private coach, who would have complete access to their learning progress in the lab, evaluating and mentoring them through assignment completion and assessments, and help the learner achieve REAL TIME results?

And then what if we could provide an upfront assessment for the learner, one which could help the learner and the coach identify one looming key performance issue in the organization at a time, one in which they want to affect change.  

And finally what if we assembled six learners in a team, where they could interact, share ideas, and have rich discussions around topics relevant to the nonprofit industry effecting their organizations?

Around these assumptions we built BLOSSOM e-Learning.
