We demonstrate the synergy between observations of the sky-averaged 21-cm signal from neutral hydrogen and interferometric measurements of the corresponding spatial fluctuations. By jointly analysing data from SARAS3 (redshift $z\approx15-25$) and limits from HERA ($z\approx8$ and $10$), we produce the tightest constraints to date on the astrophysics of galaxies 200 million years after the Big Bang. We disfavour at $95\%$ confidence scenarios in which power spectra are $\geq126$ mK$^2$ at $z=25$ and the sky-averaged signals are $łeq-277$ mK.
