g- and r-band lightcurves of SN 2020bqj (in green and red) and Type Ibn SN 2018bcc (in lime and magenta) from Karamehmetoglu et al. (2021) and Type Ibn R/r-band template lightcurve from Hosseinzadeh et al. (2017) at early phase. The lightcurve of SN 2020bqj in g- and r-band in its first fifteen days is consistent with those of Type Ibn SNe, albeit relatively fast in its rise. SN 2020bqj reached a r-band magnitude of the plateau consistent with the peak magnitude of the Ibn template, with a risetime constrained to < 5.7 days in rest-frame by pre-discovery upper limits. While this is fast compared to the template, it matches well with the risetime of SN 2018bcc.
