Small businesses are important players in the enterprise ecosystems of emerging markets. Given this situation, researchers and policy makers have been examining how to lift certain constraints in the hopes of enabling small businesses to enhance performance and stimulate economic growth. In particular, the focus has been on the design of managerial capital interventions (e.g., training, mentoring, consulting) aimed at building entrepreneurs’ capabilities and confidence.
To understand the mechanisms and main effects of interventions that intend to improve the performance of small businesses, we propose to measure the impact of an innovative business accelerator that combines training and mentorship on ‘lean startup’ approaches with growth-focused financing for small-scale entrepreneurs in Kenya and Uganda.

Experimental Details
One key element of this business accelerator intervention is to help entrepreneurs to identify a profitable business model with less risk and more speed, thereby raising the chances of developing and scaling up a minimum viable product (MVP). For this purpose, the intervention focuses entrepreneurs on implementing ‘lean startup’ tools that emphasize product experimentation, customer interaction, field-testing and refinement to uncover customer needs/problems and obtain product-market fit as quickly as possible. The intervention also includes a financing component in which entrepreneurs leverage market/demand data – from their own experimentation and interaction activities – to ‘pitch’ to an investment panel for funding to grow the sales of their MVP.

Primary Outcomes
Primary Outcomes (end points)
Main effects will be measured on firm sales, firm profits and an overall performance index.
Primary Outcomes (explanation)
Secondary Outcomes
Secondary Outcomes (end points)
In addition, we will also try to identify the mechanisms or processes through which the intervention impacts firm sales and profits. In particular, we will focus on product experimentation measures (i.e., quantity, quality, and related outcomes) and also on customer interactions measures (i.e., frequency, intensity, and related outcomes).
Secondary Outcomes (explanation)
Experimental Design
Experimental Design
Our sample consists of 1,024 entrepreneurs. We used the sampsi command in Stata for our a priori power calculations. The baseline data was collected and verified for this set of firms (N = 1,024), and the participants were randomly assigned into two experimental groups:

1. Group 1 (Treatment): 512 entrepreneurs will be offered the business accelerator intervention, consisting of training and mentorship on ‘lean startup’ approaches, as well as the opportunity to pitch for growth-focused financing at the end of the program.

2. Group 2 (Control): 512 entrepreneurs will form a comparison group who do not receive any intervention during the study period.

Randomization Method
Randomization done on a computer, using statistical programming software (Stata; randtreat command).
Randomization Unit
The randomization unit is an individual firm/entrepreneur (N = 1,024 units).
